[ViewVC] Annotation of: cvs/rxvt-unicode/Changes

rxvt-unicode changelog <= google-friendly title

TODO: xcopyarea pass broken, fix and improve
TODO: event mechanism that replaces on_user_command with something more scalable.
TODO: slipwheeling needs a keyboard grab to get key release events.
TODO: overlays collide with the way the out-of-focus cursor is being drawn
TODO: "slow" rendering mode for bidi and scripts, pango!
TODO: read property sequence is broken with respect to utf-8 etc.
TODO: slow drag selection on remote display - other things seem fast (rxvt illness, motion hints?)
TODO: better resource handling for tabbar in -pe tabbed.
WISH: investigate -pe tabbed -g 80x25 being 23 not 24 or 25 lines
      => when setting the constraints, the wm might (correctly)
         resize the outer window, which might result in a smaller window overall.
         or something like that. guys, send me a patch.
WISH: coloured pastebin
WISH: load system-wide config file even if we don't have one
WISH: look into XAddConnectionWatch, does anybody need that?
DUMB: support tex fonts
TODO: perl-shell-window? perl-unix-socket?
TODO: command line editing when icanon?
TODO: split ROW into a ROW_fast (0..total*2-1) and ROW macros?
TODO: catch exceptions when calling perl hooks
TODO: xdbe
TODO: optimise bg reeval for resize for common patterns (pixmap bigger than window?)
TODO: pack rxvt_fatal messages into the exception object
TODO: load must not cache, but global image cache must be cleaned
TODO: description into --help output?
TODO: rxvt -help => (see rxvt-XXX(1))?
TODO: xor_rect should shift right
TODO IMPL: recalc bg only when not fully covering (no alpha, repeat|extend etc..)

TODO IMPL: colour-change event with index
TODO IMPL: recalc bg always on bg colour change

TODO: document typical actions in rxvt.1.pod keysyms
TODO: warn with a graphical message when env has been modified
TODO: c&c perl socket via daemon-ext mechanism
TODO: simplify extension metainfo cache, cache on disk
TODO: URxvt::Ext::Name installs urxvt ext name and provides pod/manpage for URxvt::Ext::Name
TODO: pixel droppins idenrasm,ll,scrollup
TODO: cuu/cud and probably others default to 1 when arg is 0, not just missing, in xterm/vt102, but not in rxvt
TODO: clean up the resource vs. long option mess, especially in the manpage.
TODO: think about daemon delaying urxvt client exit.
IDEA: use harfbuzz to render combining sequences, maybe also complex scripts
TODO: rclock horribly time-biased
TODO: rclock iso date mode?
TODO: printf "\e[4:3m" - "undercurl" - should probbaly be interpreted as underline, rather than \e[43m

TODO: nmeum reports that when the wm resizes urxvt while it opens, the prompt is now somewhere in the middle
of the window, rather than near the top. this behaviour change wss part of the wrapmode fix, and should normally
prevent from readline jumping around on resizes. running urxvt with the exact geometry that the wm will assign "fixed" this.
https://github.com/exg/rxvt-unicode/commit/1eb2c326cb88ee7bae01e995a16829746bfe374e

        - fix reference counting of values returned by some perl bindings.
        - fix OSC responses with 7-bit ST (reported by Stuart Henderson).
        - change the encoding of buttons 8-11 in mouse reporting
          sequences to match xterm's and enable reporting of release
          events for them (patch by Pierre-Marc Fournier).
        - clamp coordinates in mouse reporting sequences to the number
          of rows and columns (patch by Nick Hanley).

9.31 Mon 02 Jan 2023 18:13:16 CET
        - implement a fix for CVE-2022-4170 (reported and analyzed by David Leadbeater).
          While present in version 9.30, it should not be exploitable. It is exploitable
          in versions 9.25 and 9.26, at least, and allows anybody controlling output to
          the terminal to execute arbitrary code in the urxvt process.
        - the background extension no longer requires off focus fading support
          to be compiled in.
        - the confirm-paste extension now offers a choice between pasting the original
          or a sanitized version, and also frees up memory used to store the paste text
          immediately.
        - fix compiling without frills.
        - fix rewrapMode: never.
        - fix regression that caused urxvt to no longer emit responses
          to OSC color queries other than OSC 4 ones.
        - fix regression that caused urxvt to no longer process OSC 705.
        - restore CENTURY to be 1900 to "improve" year parsing in urclock (or at
          least go back to the old interpretation) (based on an analysis
          by Tommy Pettersson).
        - exec_async (used e.g. by the matcher extension to spawn processes) now
          sets the URXVT_EXT_WINDOWID variable to the window id of the terminal.
        - implement -fps option/refreshRate resource to change the default 60 Hz
          maximum refresh limiter. I always wanted an fps option, but had to
          wait for a user requesting it.
        - new clickthrough extension.
        - perl now also requires Xext.
        - X region and shape extension functionality has been exposed to perl
          extensions.
        - RENDER extension no longer depends on ENABLE_XIM_ONTHESPOT.

9.30 Sat 27 Nov 2021 21:07:09 CET
        - the background extension did not initialise properly when automatically
          loaded via the OSC.
        - new "on_attach" hook type implemented, to initialise late-loading
          extensions.

9.29 Mon 22 Nov 2021 18:07:14 CET
        - libptytty (http://dist.schmorp.de/libptytty/) is now a required
          external dependency.
        - enable confirm-paste extension by default, can be disabled by e.g.
          URxvt.perl-ext: -confirm-paste
        - Key bindings specified with the -keysym option or with resources of
          the form URxvt*keysym work again. Such resources, as opposed to
          resources of the form URxvt.keysym, were not officially allowed but
          accepted, so ignoring them is considered a regression.
        - new option/resource -rm/rewrapMode, which sets the line rewrap
          mode to auto, never or always.
        - new option/resource -dpb/disablePasteBrackets, which can be used to
          disable bracketed paste mode sequences, as more and more programs
          abuse these sequences (typically in the name of security, but these
          sequences are not improving security). Also, bracketed paste mode
          is now under frills.
        - add manpage for urclock.
        - confirm-paste wrongly considered brackets as ctrlchars (patch by
          Jakub Wilk, debian bug #995244).
        - if urxvt cannot detect a good estimate for font width (because a font does
          not contain latin characters at all for example), it will now fall
          back to xft's max_advance_width, which works well with some fonts. It
          currently will warn about this.
        - do not render variation selectors in the default font as boxes, treat
          them as zero-width characters.
        - change combining character architecture to allow fonts to handle
          combining sequences on their own. This could allow future renderers
          to be more intelligent about these sequences.
        - use the previous enhancement to allow unicode characters outside of the
          BMP to be rendered even without --enable-unicode3, as long as an
          xft with the character is configured.
          It's recommended to stay with disabled unicode3 even more now.
        - freetype/xft have been verified to return nonsensical offsets for
          combining characters. urxvt tries to compensate to some extent,
          but diacritics will be slightly off in many cases, and far off in
          some cases (e.g. input mono).
        - when checking for overlap/careful handling, take non-basefont
          character shifts into account.
        - extensions can now request autoloading on OSC and Perl OSC sequences,
          implement this for the background, clipboard-osc and overlay-osc
          extensions.
        - the background extension will now be autoloaded when the OSC 20 or 705
          sequence is received.
        - added OSC 776 sequence to return character cell width, height and font
          ascent, which is useful when using urxvt as slave to calculate window
          size form or to row/column count.
        - matcher extension documentation now points out some requirements for
          regular expressions. the default url matching regex will now try
          to match IRLs in addition to URLs.
        - The view_start perl method now scrolls to the bottom also when the
          argument is greater than 0.
        - eval scroll actions now scroll to the bottom when scrolling down and
          there are less lines to scroll than the ones requested (reported by
          Stephen Talley).
        - allow perl-ext and perl-ext-common to override autoloaded extensions.
          this allows tabbed to disable itself in subtabs, avoiding recursive
          loading.
        - update precompose table to unicode 13.0.
        - update charset conversion tables to perl 5.32 (this only affected
          cs_koi8_u_from_unicode).
        - unicode characters > 0x100000 were not handled correctly w.r.t.
          font rendering.
        - replace bitstream vera by dejavu sans, as it has replaced the former
          almost everywhere.
        - urxvt will now try tic -x first and only fall back to tic without -x
          when tic -x fails.
        - fix urclock not erasing the old date on the clock face, causing
          overdraw, plus a host of other small fixes and improvements.
        - shave off over 1K of code size from urclock by replacing the sine table
          with a slightly less accurate fixed point approximation.
        - do not specify indentation with =over in pod, this is no longer
          needed with semi-modern pod tools and gives the formatter more
          stylistic freedom.
        - background extension did not set the "size-sensitive" flag
          when repeat mode wasn't normal.
        - extensions are now subjected to "use strict 'subs'".
        - avoid crashing when xft successfully opens a font but then somehow
          can't lock the face.
        - locale_decode/encode api methods now pass through undef unchanged.
        - fix undefined behaviour in the perl hook function, as diagnosed by clang.

9.26 Fri May 14 19:14:14 CEST 2021
        - ev_iouring.c was wrongly required during compilation, and wrongly
          not packaged.

9.25 Fri May 14 15:51:36 CEST 2021
        - for the 17.5th anniversary, and because many distributions seem to
          remove rxvt in favour of urxvt, this release resurrects rclock as
          urclock.
        - add support for systemd socket-based activation - debian bug #917105,
          freebsd bug #234276.
        - do not destruct perl on exit anymore: this might fail for a variety of
          reasons, and takes unnecessary time.
        - remove any macros from urxvtperl manpage(s), should fix debian
          bug 858385.
        - the old bg image resources are now provided by the background
          extension, and perl is thus required for bg image support. No
          configuration change is needed: urxvt autoloads the background
          ext if any bg image resource/option is present (for OSC sequences to
          work you need to enable it explicitly). The old bg image
          resources are also now deprecated; users are encouraged to
          switch to the new bg image interface (see man urxvt-background).
        - confirm-paste now checks for any ctlchars, not just newlines.
        - searchable scrollback will now ignore bracketed paste mode sequences
          (prompted by Daniel Gröber's patch).
        - drop ISO 2022 locale support. ISO 2022 encodings are not supported in
          POSIX locales and clash with vt100 charset emulation (the luit
          program can be used as a substitute).
        - perl didn't parse rgba colours specified as an array correctly,
          only allowing 0 and 100% intensity for each component (this affected
          fill and tint).
        - when iterating over resources, urxvt will now try to properly handle
          multipart resources (such as "*background.expr"), for the benefit
          of autoloading perl extensions.
        - ESC G (query rxvt graphics mode) has been disabled due to security
          implications. The rxvt graphics mode was removed in rxvt-unicode 1.5,
          and no programs relying on being able to query the mode are known.
        - work around API change breakage in perl 5.28, based on a patch by
          Roman Bogorodskiy.
        - improved security: rob nation's (obsolete) graphics mode queries
          no longer reply with linefeed in secure/default mode.
        - ISO 8613-3 direct colour SGR sequences (patch by Fengguang Wu).
        - xterm focus reporting mode (patch by Daniel Hahler).
        - xterm SGR mouse mode.
        - implement DECRQM. Patch by Přemysl Eric Janouch.
        - add missing color index parameter to OSC 4 response. Patch
          by Přemysl Eric Janouch.
        - in some window managers, if smart resize was enabled, urxvt
          erroneously moved the window on font change - awesome bug
          #532, arch linux bug ##34807 (patch by Uli Schlachter).
        - fix urxvtd crash when using a background expression.
        - properly restore colors when using fading and reverse video
          is enabled while urxvt is focused and then disabled while it
          is not focused, or vice versa (patch by Daniel Hahler).
        - fix high memory usage when an extension repeatedly hides and
          shows an overlay (reported by Marcel Lautenbach).
        - expose priv_modes member and constants to perl extensions
          (patch by Rastislav Barlik).
        - fix a whole slew of const sillyness, unfortunately forced upon
          us by ISO C++.
        - update to libecb 0x00010006.
        - disable all thread support in ecb.h as we presumably don't need it.
        - slightly improve Makefile source dependencies.
        - work around bugs in newer Pod::Xhtml versions (flags incorrect formatting codes
          in xhtml/html sections but does not interpret correct ones).

9.22 Sat Jan 23 21:07:33 CET 2016
        - NOTICE: this release updates terminfo.
        - add terminfo capabilities for various ctrl and shift-ctrl key variants
          (patch by Sebastian Schmidt).
        - fix longstanding core font encoding bug where some character
          ranges could not be mapped from unicode to the font: affected
          encodings are big5, gb2312, iso8859-8 (hebrew), jis0201 and
          ksc5601 (reported by Mikachu).
        - fix crash when the number of columns is 1 and a 0 width character is inserted
          (reported by Kuang-che Wu).
        - fix a crash when parsing an invalid color specification (reported by Kuang-che Wu).
        - fix a buffer overflow in font name parser (reported by Kuang-che Wu).
        - do not start blinking cursor if the window is unfocused (reported by
          Devin J. Pohly).
        - change the width of underline and i-beam cursor to 2 pixels (based on
          a patch by Omar Sandoval).
        - add pointerShape resource to change the mouse pointer shape
          (based on a patch by Brian Watson).
        - a keysym resource for a key which is already bound to an
          action now properly rebinds the key.
        - do not report mouse motion events if Shift is active (patch by Daniel Hahler).
        - put the alpha component last in responses to OSC color queries
          (patch by Benjamin Herr).
        - the key_press hook is now invoked before processing the
          event, as documented. This change was done in 9.21 but not
          announced and fixes debian bugs #511377, #531751 and red hat
          bug #1105069. Note that this change breaks a few scripts,
          such as mark-yank-urls, which rely on the previous buggy
          behaviour that urxvt processes the event (in particular
          keysym bindings) before invoking the hook.
        - the tabbed extension now properly refreshes the active tab
          on a key press when the mouse pointer is outside the terminal
          window.
        - add 'lookup_keysym' perl method to lookup the action bound
          to a key combination.
        - a key combination bound to 'matcher:select' can now be used
          to cycle through the matches in matcher.
        - change perl integer accessors (->width et al.) into mutators.
        - this version has been verified to work with perl 5.8.3.

9.21 Wed Dec 31 14:50:03 CET 2014
        - the "moa redraw 8-bit british vintage colour management" release.
        - NOTICE: this release updates terminfo.
        - fix pixel droppings on overdraw when a secondary core font has the
          same height but different ascent.
        - implement cvvis in terminfo as blinking cursor, to distinguish it
          from cnorm (emacs uses cvvis which is commonly a blinking cursor).
        - when xft support was compiled in, colour queries erroneously returned
          premultiplied values, this also affected internal queries, for example
          when calculating faded colour. alpha is now divided out when possible,
          which is more correct but loses colour resolution.
        - add DECSCUSR xterm extension to set the cursor to a vertical bar.
        - add 'extension:string' action, and associated on_action perl
          hook, for keysym resources that invokes actions provided by
          perl extensions. The 'perl:string' action and
          on_user_command hook are deprecated but still supported.
        - add 'builtin-string' action for keysym resources that restores string
          mappings for keys that have predefined actions in urxvt.
        - add -k option to urxvtc for killing the daemon process.
        - document urxvtd's -e/--eval option that was implemented in 9.16,
          but not documented.
        - add -dockapp option to make the wm treat urxvt as a dockapp.
        - add -mc option and multiClickTime resource to set the maximum time
          between multi-click select events (patch by Joe Peterson).
        - new 'eval' extension to evaluate arbitrary perl code with keysym
          bindings. The extension also provides methods that implement basic
          actions, such as pasting selections and scrolling.
        - the macosx-clipboard and macosx-clipboard-native extensions have been removed.
        - kuake extension now uses the kuake.hotkey resource to specify the hotkey.
        - new 'matcher:select' mode of matcher to iterate over the matches with the keyboard.
        - the 'matcher:list' feature of matcher now honours the launcher
          associated to a matched pattern.
        - speed-up matcher underlining on very long lines (reported by Edward Z. Yang).
        - fix up/down commands of searchable-scrollback so that they always move
          to the previous/next logical line with a match, if any.
        - searchable-scrollback resource has been deprecated (use keysym instead).
        - extension parameter passing is deprecated (use resource mechanism instead).
        - upgrade to GPLv3 (see COPYING).
        - compile out of the box on Solaris 10, again.
        - fix height and position of the stippled area in next scrollbar (patch
          by Thomas Otto).
        - fix off-by-one bug causing the iso14755 window not to jump out of the
          way properly.
        - fix crash that may happen if a lib to which urxvt is linked to calls setenv.
        - fix memory leak in special_{encode,decode} perl methods.
        - fix refresh bug that occurs when reverse video is set on a cell
          containing a space and with the same bg and fg colour, red hat bug
          #830236.
        - fix crash that may happen if an x error is received after a terminal
          window/popup has been destroyed already.
        - removed superfluous 0 digit from sgr terminfo sequence.
        - greatly improve colour allocation on colour-starved pseudocolour
          displays to avoid read-write cells instead of simply failing
          (this is only relevant for antique 8bpp frame buffers).
        - do not free fade colours when not doing fading (this is likely
          only relevant for antique 8bpp frame buffers).
        - do not specialcase 2 or 4 colour visuals, leading to
          simpler and actually more correct code.
        - hopefully no longer leak colours on !truecolour visuals.
        - use consistent method names (scr_recolour => scr_recolor).
        - use simpler (but slightly less bogus) formula for nearest
          colour choice (this is likely only relevant for antique 8bpp
          frame buffers).
        - remove fallback behaviour when initialising colours - the
          behaviour was inconsistent between startup vs. later and
          was only effective when valid colours couldn't be allocated.

9.20 Sat Apr 26 16:22:27 CEST 2014
        - (libptytty) fix bug that prevented urxvtd from writing utmp
          entries when using --fork (reported by Ryan Kavanagh).
        - security bugfix: window property values could be queried even
          in secure mode (reported by Conor McCarthy).
        - fix build when perl is enabled and fading is disabled.
        - fix regression that broke continuous scrolling when pressing
          and holding the scrollbar up or down button, gentoo bug #493992.
        - increase the maximum length of a command sequence to 32k bytes,
          to allow longer OSC sequences (previous limit was 2k).
        - new Ctrl-Meta-c and Ctrl-Meta-v bindings to interact with
          the CLIPBOARD selection.
        - new extension: selection-to-clipboard.
        - the extensions macosx-clipboard and macosx-clipboard-native
          are deprecated and will be removed in the next release.
          Support for the clipboard on OS X can be more generally
          enabled by setting the XQuartz preference to sync the OS X
          pasteboard and the X11 clipboard.

9.19 Sun Oct 27 17:16:07 CET 2013
        - work around perl 5.18.0 breakage in tabbed extension
          (reported by Karol Blazewicz) and in pod (Dominic Hargreaves).
        - fix regression that caused the double-click word selection to
          erroneously include a tab on the left of the selected word.
        - implement FOCUS variable and focus_fade function in background
          expression, to allow focus-sensitive background images.
        - add support for the set cursor style (DECSCUSR) control
          function.
        - honour cursorColor also when the cursor style is underline.
        - export some Color_xxx constants to Perl.

9.18 Sun Mar 24 15:33:35 CET 2013
        - fix regression that caused artifacts on resize.

9.17 Fri Mar  1 13:46:08 CET 2013
        - add shade operator in background perl extension.
        - avoid starting or ending the selection in the middle of wide
          characters to avoid artifacts (reported by Tiago Resende).
        - fix artifacts that may occur if the character in the cursor
          cell has width > 1 (reported by Tiago Resende).
        - fix regression that causes artifacts on scrolling if
          saveLines is 0 and the window is resized (reported by Bert
          Münnich).
        - fix build when perl is enabled and pixbuf and transparency
          are disabled.

9.16 Thu Dec 27 11:56:43 CET 2012
        - the "so much new stuff your eyes will pop out" release.
        - INCOMPATIBLE CHANGE: renamed urlLauncher resource to url-launcher.
        - fix processing of DEC private mode save sequences (patch by Patrick
          Hemmer).
        - perl extensions now have their own manpages, installed as urxvt-NAME(1),
          e.g. urxvt-background(1) - see urxvt-extensions(1) for a list.
        - fix disabling of cursor blink with the option-popup menu (based on a
          patch by Jan Larres).
        - the font height is not augmented anymore when lineSpace is non zero.
        - fix "new pagemap" vs. "delete pagemap" mismatch ([] vs. non-[]),
          as diagnosed by clang.
        - fix height mismatch between active and inactive cursor when
          lineSpace is non zero (patch by Stanislav Seletskiy).
        - make it compile with LOCAL_X_IS_UNIX again (reported by
          nickfailure@gmail.com).
        - completely redone background pixmap support - users can now
          specify arbitrary expressions (And programs) that calculate
          new terminal backgrounds. see the urxvt-background manpage
          for details.
        - xrender is now required for background pixmap support.
        - perl extensions can now provide commandline switches and resources
          which show up in -help etc.
        - iso14755 51 mode window now displays row and column.
        - implement a -visual switch and move that and -depth to frills, also
          warn when we can't get the requested visual.
        - new env variable: RXVT_PERL_LIB.
        - allocate all screen memory in one go and let the virtual memory
          subsystem sort it out. this simplifies code, improves access
          locality, saves a bit of ram and makes things a bit faster, too.
        - remove support for libafterimage.
        - update to CVS version of libev, for a whopping 11kb size decrease.
        - do not ship yet another copy of ecb.h, use the one in libev or
          libptytty instead.
        - selectively mark some methods as cache-hot/cache cold, which
          might speed up execution but definitely decreases codesize.
        - Fix regression that prevented the scrollbar trough color
          from being applied (reported by Derek B. Noonburg).
        - Fix the scrollbar size for rxvt style (patch by Mark Robinson).

9.15 Sat Jan 21 13:36:56 CET 2012
        - remove "using namespace std" because clang erroneously
          thinks thats an error.
        - finding a matching font (e.g. bold version of the base font)
          was broken (reported by Eamon Walker).
        - fix parsing of bg image styles. They really work now.
        - fix blurring of bg image borders when using xrender.
        - fix xrender blur on common xrender implementations that do
          not behave correctly when the same pixmap is used as source
          and destination in composite operations.
        - fix regression that caused tabbed to compute the wrong size
          for tabs.
        - allow again an empty suffix in a keysym list spec (patch by
          Sung Pae).
        - unsupported support for sun studio's CC added.
        - fix -C option on solaris.

9.14 Wed Dec 21 18:40:33 CET 2011
        - INCOMPATIBLE CHANGE: the urxvtd default socket path is now
          $HOME/.urxvt/urxvtd-<nodename>.
        - INCOMPATIBLE CHANGE: the "list" keysym expansion now requires
          loading of the "keysym-list" perl extension.
        - INCOMPATIBLE CHANGE: A scale value of 0 in the bg image
          geometry no longer enables tiling, so as to make it possible
          to disable both scaling and tiling.
        - overhaul of the bg image operations. The old operations have
          been deprecated in favour of elementary operations and
          styles built on top of the new operations and scale/position
          settings. (Emanuele Giaquinta).
        - support for libafterimage is deprecated and will be removed
          in the next release.
        - fix a crash caused by selection_check not properly resetting
          out-of-bounds mark values (can happen when extending a selection
          while scrolling up in curses programs for example).
        - do not move the selection when scrolling up and the selection is
          outside the scrolling region (Emanuele Giaquinta).
        - fix display of bold bright black (reported by Ben Winslow).
        - fix memory leak when urgentOnBell is set (patch by Nathaniel
          Filardo).
        - fix a redraw bug that occurs when a bg pixmap is set and the
          wm does not honour the size hints set by urxvt. Now urxvt
          forces the size of the terminal window to be a multiple of
          the cell size.
        - sanitise the argument of SD / SU sequences. Fixes a possible
          crash when the argument is big enough, red hat bug #711137
          (Emanuele Giaquinta).
        - correctly split long lines when scrolling.
        - urxvt now looks for perl extensions also in $HOME/.urxvt/ext.
        - add bell-command perl extension to execute a command when a
          bell event occurs (Ryan Kavanagh).
        - add set_urgency perl binding to set/reset the urgency hint.
        - consume button release event in matcher (exg).
        - keyboard accessible list of recent matches in matcher
          (Bob Farrell).
        - properly process 'keysym' sequences in tabbed when using
          'focus follows mouse' and the focus is on the main window
          but not on the active terminal window (patch by Martin
          Pohlack).
        - support for the freedesktop startup-notification protocol (patch by
          Michael Stapelberg).
        - the direction of VPR and VPB commands was reversed.
        - fix alignment of inherited root pixmap when it is a different size
          than the root window and the terminal window is off the left or top
          edge (Mikachu).
        - make $self visible in "eval perl expression" popup action, also
          handle exceptions better.
        - fix parsing of '-e' when it occurs as an option argument, such as in
          'urxvt -title -e' (Emanuele Giaquinta).

9.12 Wed Jun 29 14:34:28 CEST 2011
        - fix regression in processing of SelectionNotify events.
          urxvt would fail to request a selection if the owner did not
          support the UTF8_STRING target.
        - fix rendering of double width chars in certain circumstances, more
          likely to happen if urxvt is compiled with 256 colors support as
          urxvt runs out of fonts much earlier then. Fixes gentoo bug #358151
          (Emanuele Giaquinta).
        - restore support for 'list' syntax in keysym resources (requested by Sung Pae).
        - always premultiply colour values - while this increases differences between
          core fonts and xft, it is "more correct" in practical situations.
        - disable PTYTTY_REENTRANT option - not needed for urxvt and saves a bit of code.
        - remove lucidatypewriter from the list of fallback fonts, it was the only
          non-xft non-cellfont in the list anyway.

9.11 Mon May  2 10:34:46 CEST 2011
        - fix compilation on GNU/Hurd, debian bug #624736.
        - remove 'list' syntax for keysym resources, as it serves no useful purpose.
          If you need it, poke us and provide a use case.
        - fix alpha channel support. Premultiply alpha in colours if the visual
          supports an alpha channel, as xrender expects premultiplied alpha
          (Emanuele Giaquinta).
        - fix reply to a selection request sent by an obsolete client
          such as syncterm (patch by Marcin Cieslak).
        - fix crash when the window is resized and the overlay is active
          (Emanuele Giaquinta, reported by Ryan Kavanagh).
        - match character-wise rather than byte-wise in selection
          extension again. perl 5.8.9+ is required to avoid extreme
          slowdowns. Fixes debian bugs #523072, #616463.
        - fix a possible crash if the INCR transfer process for a
          selection property timeouts and at least one chunk is
          received. (Emanuele Giaquinta)
        - work around a memory corruption bug in xorg's XrmSetDatabase (apparently
          broken since http://lists.freedesktop.org/archives/xorg-commit-diffs/2004-March/000239.html).
        - fix memory corruption bug when custom command sequences bound to keys
          were injected into an already-full pty input buffer.
        - gdk-pixbuf is autodetected by default and preferred over libafterimage.
        - do not prepend a newline to the selection text when the starting line
          of the selection is not highlighted (Emanuele Giaquinta).
        - don't swap perl env with real env, save and restore it, just in case
          we ever get recursive perl invocations. also saves a bit of codespace
          with gcc.
        - fix various memory leaks (Emanuele Giaquinta).
        - fix typo in kIC terminfo capability, debian bug #446444.
        - document 'thickness' resource.
        - fix debian bug #504817, to the extent possible.
        - try to detect byte order at compile time, saves a couple of
          hundred bytes, if your compiler is smart enough.
        - add support for previewing the pasted data in confirm-paste
          (Emanuele Giaquinta).
        - added "newlines to spaces" option in selection-popup.
        - actually enabled solaris event ports backend (was disabled by accident).
        - revert to 38400 baud max., mission accomplished.
        - no longer create scary "pty_fill: PLEASE REPORT" message, instead,
          silently drain the input (problem is well understood now).
        - no longer swallow rob nation's own graphics mode commands.

9.10 Mon Dec 13 17:43:52 CET 2010
        - the "schmorp=north korea dickey=south korea" release.
        - INCOMPATIBLE CHANGE: make OSC 20 simpler and more correct
          (Emanuele Giaquinta).
        - if options were compiled out, this could lead to the option
          count to be defined wrongly. This is likely behind the
          failures with gcc 4.5.
        - explicitly depend on fontconfig and xrender when xft support
          is enabled. Although the public Xft api uses types from
          both, in Xft 2.2.0 these libs are private
          dependencies only thanks to an idiotic behaviour of
          pkg-config that was added to workaround cases like this one.
          Fixes linking when using GNU ld with --as-needed or GNU gold
          (based on patch by Jan Palus).
        - fix minor memory leaks in urxvt and urxvtd.
        - fix regression in urxvtd that prevented options from being correctly
          set (reported by Michal Vaner).
        - implement xterm's horribly broken 1005 mouse reporting mode,
          and an alternative 1015 mode that works in non-utf-8 locales
          and has fewer limitations.
        - fix a possible bug where mouse notifications didn't work after
          startup for the upper left corner.
        - implement our own pixbuf to pixmap rendering to get rid of
          dependency on buggy gdk-pixbuf-xlib. Only truecolor visuals
          are supported (Emanuele Giaquinta).
        - apply tinting before shading when both operations are requested.
          Previously they were intermixed when lightening and the result
          was inaccurate and confusing. Note that now a black tint yields a
          completely black image, regardless of shading (Emanuele Giaquinta).
        - avoid spurious redraws of the bg image when bg is transparent or
          when using 'root' mode (Emanuele Giaquinta).
        - fix build on XFree86.
        - dynamically number options according to compiletime requirements.
          For the extra saved byte. Or so. Yay.
        - start options at one, not zero. Wastes a bit per terminal. Maybe.
          saves 50 instruction bytes. Possibly.

9.09 Sat Nov 13 01:39:07 CET 2010
        - NOTICE: this release updates terminfo/termcap.
        - the bestest release ever.
        - it was verified that urxvt handles µ and μ correctly.
        - add support for blending and blurring with XRender (Emanuele Giaquinta).
        - add support for using gdk-pixbuf as image backend (Emanuele Giaquinta).
        - cleanup and minor fixes of the image code (Emanuele Giaquinta).
        - new perl extension "confirm-paste" (Emanuele Giaquinta).
        - new on_tt_paste perl hook and tt_paste perl binding (Emanuele Giaquinta).
        - new on_bell perl hook (Emanuele Giaquinta).
        - searchable-scrollback no longer ignores the first line
          (Emanuele Giaquinta).
        - properly set VSTATUS in termios for *BSD (reported by Ed Schouten).
        - fix utmpx detection on upcoming FreeBSD 9.
        - Use COMPOUND_TEXT encoding for WM_NAME/WM_ICON_NAME value when it
          is not fully convertible to STRING (patch by James Cloos).
        - fix a buffer overflow that would cause wrong key sequences to
          be generated for numpad keys (introduced in 9.05).
        - fix definition of sgr0 to work around limitations in luit.
        - extend ISO 14755 5.4 mode to also print the font name of the
          characters other than first one in the selected cell
          (Emanuele Giaquinta).
        - new iso14755 option to disable ISO 14755 at runtime
          (Emanuele Giaquinta).
        - make sure pagewise scrolling scrolls at least one line
          (found by Mikachu).
        - remove deprecated OSC 18 / 19 and make OSC 17 / 19 apply to
          highlightColor / highlightTextColor (Emanuele Giaquinta).
        - add highlightTextColor resource to change the foreground colour of
          highlighted characters (Emanuele Giaquinta).
        - make highlightColor apply also to selected cells with reverse video
          but not to non selected cells with reverse video (Emanuele Giaquinta).
        - remove colorRV resource (it was enabled only with frills off).
        - fix numlock handling, the most longstanding bug to date (Emanuele Giaquinta).
        - reduce the number of custom bits to 4, to make room
          for 256 colours.
        - add support for 256 colors (Emanuele Giaquinta, Marc Lehmann).
        - add rxvt-unicode-256color terminfo and use it by default in 256 colors mode.
        - update rxvt-unicode terminfo to state 7744 colour pairs to cover all
          88*88 possible pairs.
        - actually added macosx-clipboard-native, which should have been in
          the 9.07 release but had been forgotten.
        - fix hang if DECAWM is not set and there are not enough columns to insert a
          character (Emanuele Giaquinta).
        - cub1 ("backspace") will now respect wrapping when past the rightmost column,
          working around a shortcoming of most tty line discipline's line editing.
        - add support for grabbing the clipboard selection and extend
          selection{_clear,_grab,} perl bindings to optionally work
          on the clipboard selection (based on patch by Dana Jansens).
        - no longer force CERASE to BACKSPACE - use the system default. affects
          default value for VERASE only when no compatible setting for
          backspacekey was given.
        - use higher than 38400 baudrate setting, if detected.
        - erase screen would clear to the wrong background when blinking
          was enabled (which selects high intensity under some circumstances).
        - scr_kill_char didn't touch the line.
        - upgrade and port to libev-4.01.
        - enabled solaris event ports and kqueue backends (if available).

9.07 Wed Dec 30 07:07:18 CET 2009
        - port to glibc-2.10 changes (strchr etc. returning const char *
          in C++), based on patches by Milos Jakubicek and Oliver Mader.
        - the binary search algorithm to find precomposed characters
          was faulty, skipping some possible combinations (found by
          Mikachu).
        - new -letterspace option, patch by Mark H. Wilkinson.
        - enable --mlock option for urxvt with frills on
          systems supporting it (patch by Russell Harmon).
        - urxvt did not compile without frills enabled
          (analysed by Matthew Rosewarne).
        - correctly reset the mbstate after an illegal
          input sequence when handling terminal output (Emanuele Giaquinta).
        - avoid redrawing wide characters with combining enabled on every
          refresh (reported by Mikachu).
        - fix a typo preventing the ISO-646.1991 character set from being
          recognized (http://achurch.org/patch-pile/).
        - better warning for x11 font encoding detection failures, also,
          try to deduce encoding from both font properties and name
          (adapted from http://achurch.org/patch-pile/).
        - resizing the window with the scrollbar disabled via the escapes
          sequence could make the window bigger again (Mikachu).
        - make sure the alignment for fd passing control messages
          is correct and work around some NetBSD issues (Taylor R Campbell).
        - update to libptytty 1.3.
        - replace macosx-clipboard by a nicer version by Reza Jelveh, and move
          the old version to macosx-clipboard-native.
        - document the -uc option (Emanuele Giaquinta).
        - assertions in libev are now enabled depending on frills.
        - update AnyEvent implementation to version 5.23 API.
        - work around arrogant bsd idiocies again: netbsd spills the default
          namespace with lots of symbols "for gnu/gcc compatibility" even
          though neither of them does it, and then calls the rest of the world
          in need of fixing. go figure.
        - on_keyboard_command is on_user_command (patch by Michael Witten).
        - setting the selection from perl will now reset the selection screen
          to the current screen. the screen can be manipulated using
          the new ->selection_screen method.
        - implement --enable-assert configure option and get rid of DEBUG_STRICT
          (based on patch by Emanuele Giaquinta).
        - fix printpipe data output (patch by Emanuele Giaquinta).
        - allow `xxx' quoting style for perl selection.
        - upgrade to libev-3.9 prerelease.
        - updated compose tables to unicode 5.2.0.

9.06 Sat Nov  8 17:47:18 CET 2008
        - NOTICE: this release updates terminfo/termcap.
        - updates libev to 3.48.
        - the aterm code now frees the as visual and image manager objects
          when a window was closed.
        - do not (wrongly) adjust the virtual line length inside
          scr_insdel_chars/ERASE (Miroslav Lichvar).
        - fix an issue where wide tab characters caused character shifts
          when part of them was deleted (tracked down by Miroslav Lichvar).
        - artificially enlargen the previous character at the end of a line
          when trying to output a character that doesn't fit. looks ugly, but
          makes copy&paste work.
        - remove bogus "setuid/setgid security issues" from rxvt.1.pod, they
          no longer apply.
        - the urgency hint is now cleared on both focus in and focus out.
        - cache urgency hint locally to avoid server rtt on every focus change.
        - perl 5.10 needs PERL_SYS_INIT3 on hppa.
        - ignore byte-order marks and do not treat them like combining characters.
        - fix build issue when CURSOR_BLINK is not defined (Emanuele Giaquinta).
        - do some µ-optimisations to the character fast path.
        - use a less cunning, but more robust algorithm to avoid one terminal
          monopolising the whole process by outputting a lot of text.
        - try to work around linux first breaking sched_yield and now breaking
          the only known workaround.
        - new option -icon to set _NET_WM_ICON (based on patch by Frank Schmitt).
        - initialise the as visual only on demand, instead of unconditionally,
          to save memory in the common case of not using visual gimmicks.
        - try to work around bugs in a few wm's that erroneously resize
          client windows on hint property updates by temporarily
          disabling size hints.
        - implement the DECSTR soft reset sequence and use it for tput init,
          and make hard RIS and DECSTR both reset more private modes, such
          as mouse reporting.
        - redundantly clear mouse reporting and a few other states in
          tput init/tput reset, for older urxvts.
        - partial/full clear screens did cause flickering and possibly pixel
          droppings when urxvt viewed the scrollback buffer.
        - use current rendition style in DCH sequence.
        - the 132/80 mode switch no longer forces a screen reset.
        - add an osc sequence to change the border colour (Emanuele Giaquinta).
        - new perl extension "overlay-osc", for status displays and the like.
        - fix some minor cursor drawing issues with overlays by allowing
          overlays to modify screen flags (to disable the cursor themselves).
        - work around programs not restoring rstyle before rmcup
          (analysed by Miroslav Lichvar).

9.05 Sun Jun 15 20:09:20 CEST 2008
        - new option --cd/chdir to set the starting working directory.
        - tabbed extension now starts in the "correct" working directory.
        - work around fedora 9 providing isastream but not the relevant
          header file for it (report by Tuncer Ayaz).
        - upgrade libev, fixing a bug in the select backend.
          with more than 31 file descriptors on non-linux 64 bit systems.
        - correctly reset the multibyte state to the initial one
          after EILSEQ (patch by Neil Booth). This fixes the
          issue of rxvt-unicode not properly displaying text after an illegal
          sequence on NetBSD and probably other systems.
        - more intelligent property handling with -pe tabbed, works around
          broken window managers (kwm et al.), saves bandwidth and should
          help working window managers as well.
        - made tabs moveable (based on a patch by Petr Machata).
        - implement ESC [ 3 K as a more rational alternative to ESC [ 0 K.
        - support relative paths for RXVT_SOCKET in urxvtd.
        - the tabbed extension now blindly copies over all (rxvt-) resources
          from the toplevel window to the children.
        - better diagnostic on 0x0 window geometries.
        - update AnyEvent API to version 3.4 and above.
        - document the default value of :0 for DISPLAY.
        - rename perl method XChangeWindowProperty to XChangeProperty.

9.02 Tue Jan 29 11:58:36 CET 2008
        - the "exg makes everybody happy" release.
        - fix build with !xft.
        - always compile in plain style scrollbar (simplifies code and looks great).

9.01 Sat Jan 26 20:49:27 CET 2008
        - be more aggressive about handling X events, this seems to be required
          with newer xlibs (should fix the "screen stays black until event is
          received" problem, again :)
        - add buffered resource to control xft double-buffering.

9.0  Fri Jan 25 19:34:04 CET 2008
        - fix a crash bug where urxvtd would crash when urxvtc was called
          with wrong arguments (I wish debian maintainers in general would
          report bugs and their proposed fixes to the original package maintainers
          instead of sitting on them for good measure to see if anybody notices).
        - drawing xft compose characters was causing garbage to be drawn.
        - correctly clear xft character background in all cases.
        - implement bracketed paste mode (xterm private mode 2004).
        - improve documentation on alpha channel handling, make urxvt
          work better on servers lacking the RENDER extension when alpha
          channels or background images are used.
        - check for refresh after initialising to avoid staying blank
          till the first event arrives. or so.
        - the FORCE_UNBUFFERED_XFT feature macro works again.
        - continuously update transparency while moving/resizing now.
        - OSC 39/49 are deprecated and aliased to OSC 10/11.
        - cub1 now acts as advertised (and ignores the "wrapped" state).
        - the 132/80 mode switch now forces a height of 24, too, and
          resets the terminal.
        - scrollbar code cleanups.
        - stopping children is no longer confused with children exiting.
        - removed (undocumented) #aarrggbb format.
        - updated to libev 3.0.

8.9  Mon Dec 24 07:51:40 CET 2007
        - fix the issue where urxvtd would not immediately close a window
          when the command exited but only on the next X event.
        - changed terminfo file not to use application keypad mode.
        - fix the issue where making a selection in one urxvtd window
          would not clear it visually in another.
        - fix an issue of urxvt not getting background pixmap updates
          and flickering after bg pixmap changes (reported by Mikachu).
        - fix redraw bug in xterm scrollbar with -sr (reported by Mikachu).
        - correctly provide dependencies for libev (µikachu).
        - minor code reorganisations and cleanups.
        - be more robust in case the urxvt-popup extension cannot be loaded.

8.8  Sat Dec 15 19:40:39 CET 2007
        - option -C was aliased to all unsupported options, activating
          options that shouldn't be compiled in, leading to interesting
          effects.
        - updated libev, working around a bug in linux 2.4, curing the
          symptom of urxvt not closing its window on shell exit. also
          fixes a problem with urxvt not refreshing.
        - the text blink callback was called even when no blinking
          text was visible.
        - pre-8.4 slipwheeling behaviour has been reinstated, with
          some minor improvements.
        - streamlined x events processing to only flush once per
          display and not once per terminal window.
        - quite a bit of minor code cleanups and codesize optimisations.

8.7  Sun Nov 25 10:23:49 CET 2007
        - update libev with an important bugfix that would cause crashes
          when closing windows (when using rxvtd, and update is recommended).
        - do not compile in the block builtin graphics with --disable-frills.

8.6  Fri Nov 23 14:10:57 CET 2007
        - upgrade libev to disable kqueue on anything but netbsd as it
          seems to be broken everywhere else w.r.t. ptys.
        - allow for spurious event notifications, as at least epoll and
          especially solaris ports like to lie about them (symptoms:
          urxvt "hangs" until there is some x11 related activity).
        - -keysym command line options are now subjected to xlib parsing.
        - add 'xrm' option analogous to Xt one.

8.5a Wed Nov 21 10:16:33 CET 2007
        - make it compile with --disable-transparency.

8.5  Wed Nov 21 05:19:20 CET 2007
        - expect major portability issues in this release: please test and report.
        - converted from the veritable io manager event loop to
          the high performance libev (http://software.schmorp.de/pkg/libev).
        - minor tuning to the perl selection (include single words and more quoting chars).
        - fix memory leak in pixmap code.
        - fix a serious bug while setting the XIM destroy callback
          on (typical) 64 bit systems.
        - automove-background functionality re-implemented internally using :root op in pixmap
          geometry string. For example: rxvt -pixmap "image.jpg;:root"
        - do not link rxvtc against every lib on the planet anymore.
        - parallel builds should work once more.

8.4  Sat Oct 27 14:02:13 CEST 2007
        - overhaul of the transparency/pixmap code (sasha).
        - fix possible race between visual bell and poweron.
          (reported by Martin von Gagern, gentoo?).
        - urxvt -e no longer crashes the child.
        - fixed some minor memleaks on incorrect usage or
          missing DISPLAY.
        - implement xterm 1002/1003 mouse tracking modes (exg).
        - source code organisational cleanups (exg).
        - updated io_manager.

8.3  Wed Aug  1 20:21:31 CEST 2007
        - new option: skipScroll/-ss, enabled by default.
        - go with the times and expect x11 library files in /usr/lib, not
          /usr/X11R6/lib.
        - initial transparency improvement/afterimage support
          patch by Sasha Vasko.
        - add urgentOnBell resource to set the urgency hint
          (patch by Philip Paeps).
        - do not process focus events caused by grabs
          (patch by Mikachu).
        - add iso14755_52 resource to disable iso14755 5.2 (exg).
        - add binding for backspace in iso14755 5.1 to remove the last
          digit (exg).
        - better option handling, support more than 30 options (exg).
        - nuke reconf script, serves no purpose anymore.
        - fixed and documented matcher/on_user_command processing in matcher
          extension (tpope).
        - compile out of the box on Solaris 10 (exg).
        - fix MappingNotify events (reported by Stephan Walter).
        - zero-initialise mwmhints, this seems to solve all sorts of minor
          problems.

8.2  Sat Feb 17 21:35:28 CET 2007
        - fix make depend in src/, reported by exg.
        - fixed typo in urxvt::GET_CUSTOM, causing the result to be wrong.
          (patch by Sergey Vlasov).
        - unbundled iom perl interface somewhat.
        - scrollbar-xterm now uses the selected scrollColor instead of fg
          (found by Aiviru).
        - disabled linux kernel bug workaround again: disabling it gives
          a 50% speed hit on affected machines, while enabling it gives
          a similar speed hit to screen, which is likely the more common
          case to work around for :/
        - urxvt::rend2mask perl function, and utilization of it by matcher
          (patch by Moshe Kamensky).
        - use perl:matcher on a keysym to open most recently displayed URL.
        - with matcher, when multiple patterns match, last wins, not first.
        - fix make and make install with srcdir != builddir (exg).
        - updated bundled libptytty to fix a bug where the tty would be kept
          open (see the libptytty ChangeLog for details).
        - delay setting the IUTF8 flag to after the tty settings have been
          set so its value does not get lost (reported and analysed by Andrei
          Paskevich).
        - rip out support for obsolete sgtty.h interface.
        - rip out support for non-POSIX termios variants.
        - update libptytty.
        - update iom.C, make it call ptytty::sanitise_stdfd on init.
        - when !XFT, change rounding of colours to use a less correct formula to
          meet user expectancies (#aaa becomes #a000a000a000 not #9f9f9f9f9f9f).
        - change the starting offset of the pixmap set with backgroundPixmap
          from (50,50) to (0,0) (exg).
        - fix a typo in button_release, now meta-button2 request the value of
          the Clipboard selection as it should (patch by Serge Koksharov).
        - fix a bug in drawing a cell with a nonspacing char when using an xft
          font with inheritPixmap and tintColor (exg).

8.1  Thu Dec  7 22:27:25 CET 2006
        - ｹﾘｽﾏｽﾌ゚ﾚｾ゙ﾝﾄ - zomg!!1, it's too early!!!
        - fix the assumption that chars < 256 are single-width. Now
          only assume this for codepoints 32 to 126 (reported by Dai.H.).
        - $term->strwidth returned wide chars as width 1, because some jerk
          confused min and max. Fixing this also fixes xim-onthespot.
          Reported by Takano Akio.
        - secondaryScroll is now enabled by default (as per the manpage),
          reported by exg.
        - correct the description of [percent]color rgba format in the manpage.
        - incorporated macosx-clipboard extension by Samuel Ljungkvist.
        - ignore (some) useless focus events (reported by mmc).
        - updated compose table to unicode 5.0.0.

8.0  Thu Nov  2 18:35:19 CET 2006
        - combining characters cleared the area instead of creating an overlay,
          thus losing the ability to draw combining characters properly in most
          circumstances (reported by exg).
        - specified fonts were incorrectly morphed to bold/italic according to the
          basefont, even if explicitly specified (tracked down by tpope).
        - fixed urxvt::strwidth to calculate width in the same way as screen.C.
        - fix a crash caused by passing negative widths to overlay functions.
        - added 'matcher' extension by tpope, replacing the mark-urls extension.
        - improve url regex to match anything www.* (tpope).
        - fixed bug with outline cursor color being wrong after xft fonts.
        - update to libptytty-1.0.
        - give proper diagnostic when RXVT_SOCKET is too long instead of
          corrupting the stack (patch by exg).
        - display current terminal locale in option menu.
        - urxvtd no longer crashes when the client sends an inaccessible
          working directory (reported by Roland Baer, possibly fixes gentoo
          bug #143985).
        - fixed many minor issues reported by Roland Baer.
        - Leonid Khramov spotted a minor glitch in rxvtfont.C that
          should not have any consequences, but was buggy nonetheless.
        - manpage fix by exg.

7.9  Mon Aug  7 18:16:07 CEST 2006
        - fix the crashing bug people encountered with 7.8 + urxvtd + perl
          + transparency. Ought to fix debian bug #380348.
        - fix urxvtc.1.pod: it actually claimed -pty-fd would not work. But
          it does! :->
        - rxvt_fatal() in case the locale string is too long for our static buffer.
        - fixed many, many, typos in the manpages (patch supplied by ves).

7.8  Mon Jul 17 21:00:46 CEST 2006
        - INCOMPATIBLE CHANGE: this version will always read ~/.Xdefaults,
          earlier versions only read it if display-resources (usually from
          .Xresources) are not set. This avoids the #1 FAQ ("why isn't my
          resource used") and seems to be logical behaviour, too. .Xdefaults
          resources have a lower priority than display-specific resources.
        - add "kuake" perl extension that does a similar thing to the kuake
          terminal emulator (see man urxvtperl).
        - use less "correct" color scaling that is compatible with libX11 and
          Xft (avoids off-by-one colors resulting in striped backgrounds).
        - the "depth" resource is now respected.
        - preset the searchable-scrollback pattern with "(?i)" to default search
          to case-insensitivity. Will automatically be cleared when typing an
          uppercase character.
        - add FORCE_UNBUFFERED_XFT define to features.h.
        - re-enabled highlightcolor support with --enable-frills, based on
          a patch by Martin Stubenschrott.
        - double-buffered xft drawing did suffer from pixel offset issues
          when pixmap transparency was enabled.
        - strategically add # to the url-match regexes, as we really want to
          match common URIs not common URLs. Reported by Aaron Griffin.
        - moved on_osc_seq to on_osc_seq_perl and added a more
          generic osc_seq.
        - fix a bug causing double callback invocations when perl hooks
          were invoked recursively.
        - the automove-background extension now properly works when the
          pixmap gets reset with an osc sequence (sqweek).
        - selection-pastebin did not work properly with non-latin1-characters.
        - apply colorUL only when the text colour is the default fg
          (patch by Wu Fengguang).
        - removed rxvtlib.h from the tarball, it had no reason to be there
          (spotted by Decklin Foster).
        - fix compiling with TRANSPARENT but !XPM_BACKGROUND, as reported
          by omatunto_.
        - slap in a using namespace std, might help on platforms that don't
          follow C++ closely enough.
        - fix mailto url regex, spotted within milliseconds by Jost Krieger.
        - applied fade_color_update_func.patch by WU Fengguang.
        - fix a bug where (due to an optimisation in av_delete), hiding the
          bottom-most overlay would hide two overlays.

7.7  Tue Feb 21 12:32:49 CET 2006
        - use double-buffered drawing (xft fonts only). On many driver/hardware
          combination this actually increases xft drawing speed, at the expense
          of more network bandwidth and slight nausea on the side of the author.
        - readline perl extension now requires shift-click instead of a normal
          click, and eats the click.
        - tabbed perl extension now supports -e.
        - disabled graphics-exposures on the main drawing GC, report any
          refresh bugs please.
        - improve property handling for -pe tabbed: avoid unnecessary property
          changes (for kde's benefit) at the expense of extra round-trips,
          improve size hint setting.
        - modified XIM according to a patch sent by Takano Akio that sets
          the preedit rectangle for OverTheSpot, which helps some input methods
          to correctly position their preedit window.
        - un-optimise the line clearing on newly scrolled-in lines a bit: the
          former reasoning was that any fg colour on default bg looks the same
          in empty spaces, but that's not true when reversing (e.g. selection),
          so also check for matching fg colours. This fixes the problem where
          selecting newly scrolled-in lines would exhibit wrong colours.
        - fix a bug in the perl interface causing focus in events to generate
          focus out perl events, causing bad focus effects with -pe tabbed.
        - fix a race resulting in a crash on exiting.
        - fix a with --disable-xft that caused xfreecolors to be called on
          colors never allocated, resulting in aborts (reported by Paco-Paco).
        - resources on non-initial screens weren't refetched correctly
          (reported by Paco-Paco).
        - fix a bug in xcopyarea pass and _disable_ it, as it seems not to be
          working in either rxvt-unicode nor in the original rxvt.
        - removed undocumented -exec alias for the -e option.

7.6  Fri Feb 10 08:52:36 CET 2006
        - changed interpretation of [alpha] colour prefix.
        - +option now really sets the option to default, instead of using the
          resource value.
        - options that require an argument now really _require_ an argument.
        - the tabbed extension now forwards focus and key events to the
          relevant tab window.
        - tab colours are now configurable and have sensible defaults
          (initial patch by hednod).
        - option menu is extendable, readline, selection and
          selection-autotransform can now be disabled/enabled at runtime.
        - forcing a configure event to tabbed subwindows with -pe tabbed, for
          the benefit of automove-background.
        - the automove-background extension added a wrong constant offset.
        - force refresh of XA_RESOURCE_STRING on virtual reconnect.
        - return exit status 2 in urxvtc when urxvtd couldn't be contacted.
        - the linux yield hack is back, now using usleep, and enabled only on
          __linux__.
        - further round trip eliminations in the !XFT case by remembering
          the colour components.
        - plain scrollbar works better with -sr.
        - fixed half-shadow scrollbar look.
        - more colour rtt optimisations.
        - properly(?) free colours on window close.
        - reorganised the FAQ into multiple sections.
        - add ISO646.1991-IRV to the list of supported codesets.
        - minor libptytty update.

7.5  Tue Jan 31 15:15:43 CET 2006
        - further improvements to the careful mode detection, and font width
          detection:
          - fully double-wide fonts will now be correctly treated,
          - overlap detection was improved.
          - detect totally broken fonts (usually synthesized by xft).
          - careful mode forced refresh sometimes clashed with blinking,
            causing unnecessary screen redraws.
        - better handling of XFT combining characters.
        - enable antialiasing for some replacement fonts, as they
          might get used for other encodings which really need it, later.
        - remove spacing=100 from all default fonts, as this creates totally
          weird spacing (5 times normal) with xft.
        - removed iso10646 fallback, as xorgs iso10646 encoded fonts are mostly
          broken.
        - removed gnu unifont fallback, all combining characters are broken.
        - replace named colours by xorg's rgb.txt equivalents, to
          reduce round trip time on startup, and short-cut allocation
          of rgb:rr/gg/bb for xft.
        - short-cut allocation of rgb values in the xlib case
          (patch by Paco-Paco).
        - overhauled color management: smaller codesize, alpha support.
        - support "rgba:rrrr/gggg/bbbb/aaaa" color specifications and
          an "[alpha]" prefix.
        - try to work around Xft and Xrender forcing everything to be 100%
          transparent. Long Live Xft!
        - do not include X11/Intrinsic.h anymore, directly use
          Xlib/Xutil/Xresource directly.
        - try to find a nearest matching color when color allocation fails
          on a pseudocolor screen.
        - SYNCCVS: compared to rxvt-cvs 2006-01-28, no relevant changes.
        - fix version report (DA) (which was unfortunately broken).
        - changed version number report again, now to emulate xterm closer.
        - added the OSC sequence 702 to detect the urxvt version number.
        - small configure updates.
        - further RTT optimisations.
        - backported clean-up patches for makefiles and documentation from
          the debian package.
        - updated doc/rxvt-unicode.spec file. It's still not maintained here,
          but much newer than the old one.

7.4  Sat Jan 28 15:26:27 CET 2006
        - screen background wasn't always erased properly when scrolling,
        - re-enabled clearing optimisation disabled in 7.4pre.
        - small configure updates for libptytty.
        - fixed version options: line output.
        - removed stoopid debugging message left in the code.

7.3  Wed Jan 25 22:47:35 CET 2006
        - don't let iso14755 or mouse reporting get into the way of perl
          (could lead to global grabs never being cleared).
        - experimental OnTheSpot editing support (-pe xim-onthespot).
        - moved Shift-Button2 paste combination to Meta-Button2.
        - the cutchars resource will now be respected and used by the
          selection extension.
        - added the "remote-clipboard" extension which just runs external
          commands to fetch and store the selection data.
        - added -depth switch that tries to get a different visual depth
          than the default (replaces the old PREFER_24_BIT logic).
        - removed (unused) arabic presentation form composing sequences.
        - be more strict when deciding that a core font glyph is too wide and
          needs the careful rendering mode.
        - allow more leeway for italic fonts when deciding that a character is
          too wide and needs careful mode.
        - redraw even more characters around characters using careful mode.
        - made selection-pastebin fully asynchronous.
        - reduced number of server turnarounds at startup by allocating
          atoms only once per display.
        - renamed on_keyboard_command to on_user_command.
        - changed version sos (ESC [ > c) response to be more compatible with
          xterm.

7.2  Sun Jan 22 21:58:16 CET 2006
        - bugfix: urxvt (not urxvtd) did not correctly handle multiple
          environments necessary, which resulted in segfaults within
          getenv (reproducible: urxvt -fn 9x15, open a menu once,
          ctrl-shift-672c).
        - bugfix: the selection speedup in in 7.1 unfortunately caused
          non-ascii characters to enlarge/move the selection.
        - bugfix: resizing sometimes leaked lines from the secondary to
          the primary screen.
        - bugfix: reducing window size while large amounts of text were output
          could lead to an assertion failure.
        - added "tabbed" extension that provides a crude tabbed terminal.
        - added "readline" extension that allows cursor positioning
          via mouse clicks.
        - now it is possible to insert the value of the CLIPBOARD selection
          with shift - mouse button 2.
        - fixed the automove-background extension to ignore coordinates
          in non-synthetic events.
        - created a separate libpty for portable and secure
          pty/tty/utmp/wtmp/lastlog handling, and include it in rxvt-unicode.
        - the non-terminfo visual bell now works asynchronously, so
          continuous ASCI BELs in one terminal do no longer monopolise the
          whole urxvt[d] process.
        - support some *BSD makes (for the time being, gnu make is a safe bet).
        - work around bugs in FreeBSD's gcc.
        - implemented some *BSD fixes in configure.
        - removed support for obsolete offix dnd protocol.

7.1  Thu Jan 19 20:25:34 CET 2006
        - setuid/setgid operation is now _encouraged_: security has been
          improved by moving privileged operations into a separate process
          and permanently dropping privileges within the terminal. This
          makes it possible to remove security checks from the perl code
          and gives a much safer feeling when urxvt needs to run with
          special privileges.
        - perl taint checking disabled, as urxvt no longer runs setuid/setgid
          itself.
        - new perl extension automove-background that can be used to get
          the same effect as pseudo-transparency with any pixmap.
        - new perl extension example: perl/selection-pastebin, can be used to
          e.g. upload the selection to a webserver and generate a url, or
          similar stuff.
        - use the scrollback buffer even when the scroll region doesn't
          span the whole screen, as long as it starts at row 0. Helps
          for programs displaying a status line at the bottom.
        - selection popup now shows selection in dec/hex/oct.
        - perl/selection: matching on unicode characters in the selection
          code was O(n²), which equals infinity in some degenerate cases
          :-> Matching is now done on UTF-8, which makes it almost instant.
        - perl/selection, perl/selection-autotransform: regexes are now
          being interpreted in the locale urxvt was started.
        - implemented override-redirect option and enabled it on menus,
          as kwin puts our windows behind the terminal (what a shoddy wm).
        - fixed struct utmp check in configure for OpenBSD.
        - complete overhaul of the pty/utmp management stuff and configure
          (Emanuele Giaquinta=exg).
        - add tsl/fsl and related capabilities to the terminfo description,
          to set the window title.
        - swap the environment in some more cases. This hopefully fixes
          some segfaults that might be caused by xft asking for env variables
          at the wrong time.
        - removed src/strings.C and src/menubar.C. No menubar support
          anymore.
        - removed all traces of SMOOTH_REFRESH.
        - nuked QNX support.
        - made some fixes to xpm offset and scaling code.
        - perl-overlays and refresh hooks were not applied in correct order.
        - changed coordinate-system of view_start/nsaved to be top to bottom.
        - iom extended to support listening for child exits.

7.0  Fri Jan 13 14:02:18 CET 2006
        - added sections for DISTRIBUTION MAINTAINERS and about
          SETUID/SETGID to the FAQ.
        - selection, searchable-scrollback, selection-popup and
          option-popup extensions enabled by default.
        - increased xft drawing speed for problematic fonts. The effect
          will likely be small as 99% of the xft slowness is server-related.
        - perl: much increased functionality, better overlays, popup support
          and much much more.
        - perl: urxvt::line now can set via ->t and ->r.
        - perl: changed interpretation of --perl-ext-common and -pe.
        - perl: finally implemented --perl-eval.
        - perl: non-blocking anyevent support.
        - perl: run tainted and ignore perl-eval/perl-lib if started
          setuid/setgid.
        - free the resource database: this plugs a massive memory leak. As a
          side effect, it also gets rid of XGetDefault calls.
        - free one of the cursors, fixes a small memory leak.
        - built-in (as opposed to terminfos) visual bell was broken/too fast.
        - applied minor cleanups by Ladislav Michnovic.
        - applied pty handling cleanups and improvements (Emanuele Giaquinta).
        - mark-urls launch-on-click by jepler.
        - removed "small" resource parsing function, as it wasn't really
          compatible, and not really small either.
        - removed PATH_ENV and PATH file search support.
        - removed support for locale-specific app-defaults file.
        - fixed a bug where out-of-bounds colour sequences could lead
          to crashes.
        - limit colour changing to the standard 88 palette instead of all
          colours.
        - XTerm_Color01 sequence returned wrong results in query mode.
        - iom.C now checks against destructed io_manager when unregistering.

6.3  Wed Jan  4 22:37:10 CET 2006
        - SECURITY FIX: on systems using openpty, permissions were
          not correctly updated on the tty device and were left as
          world-readable and world-writable (likely in original rxvt,
          too), and were not restored properly. Affected are only
          systems where non-unix ptys were used (such as most BSDs, not
          GNU/Linux). (found, patched and debugged by Ryan Beasley).
        - meta8 support was forcefully enabled in most configurations.
          restored configurability of this (useless) feature (reported
          by Mikachu).
        - optionally embed a perl interpreter, which can be used for more
          intelligent/customized selection support, visual feedback,
          menus, tabs etc. See the the urxvtperl manpage, the -pe option,
          perl*-resources and keysym resources. Not everything is there yet.
        - try to be more clever about differing font sizes and their ascent.
          Not guaranteed to work, but works better in most cases now.
        - fix directory permissions on install.
        - implemented option to disable built-in line drawing characters
          and fall back to the font ones (patch by Martin Pohlack).
        - disabled sched_yield support: the linux version is just too useless
          (it schedules nice'd processes before the own one for extended
          periods). Too bad, it could reduce system time by a factor of 5 here.

6.2  Mon Jan  2 16:03:01 CET 2006
        - implemented intensityStyles option which enables/disables bold/blink
          selecting high intensity foreground/background colours, suggested by
          Chuck Blake.
        - move iso14755 character feedback box out of the way if it would
          obscure the mouse cursor position.
        - replaced callback.h by a fixed version from gvpe that correctly
          returns the callback result (affects new -pty-fd semantics in urxvtc
          on a few architectures). Reported by darix.
        - include one trailing space in rectangular selections to indicate
          the inserted newline (yeah, weird, but visually more pleasing).
        - try to use sched_yield to (drastically) improve terminal data
          transfer efficiency.
        - further minor cleanups.

6.1  Tue Dec 27 13:23:40 CET 2005
        - update iso8859-7 table (euro and drachma round-trip et al.).
        - fix a crash when the selection scrolls out of the scrollback
          while the user still drags.
        - selections that were partially scrolled out of the window were
          not drawn correctly.
        - lines newly scrolled in were not initialized properly, leading
          to extremely long lines and (hopefully) some segfaults.
        - iso14755 overlay position was wrong.
        - iso14755 overlay now displays rendition info, too.
        - use unicode white space class instead of hardcoded values for
          stripping whitespace.
        - do whitespace stripping on rectangular selections.
        - slight cleanups in src/features.h.

6.0  Sat Dec 24 13:58:56 CET 2005
        - make it compile without SMART_RESIZE again.
        - enable slow link support by default.
        - fix relative cursor-positioning not respecting scrolling regions
          (also a bug in original rxvt).
        - initialize termios structure to zero when fetching it fails
          (see http://www.freebsd.org/cgi/query-pr.cgi?pr=84647 for a
          partial patch).
        - bump max columns/rows to 10000 each.
        - bump max savelines to 10000000.
        - -pty-fd now passes the urxvtc fd to the urxvtd process.
        - avoid linking against -lnsl/-lsocket/-lxpg4 unless necessary.
        - major code cleanup (still not complete, though).
        - implement -hold option.
        - _major_ rewrite of internal buffer handling:
        - re-flow on resize, lines get wrapped instead of winged.
        - circular line buffer (substantially speeds up scrolling).
        - slightly less code + data memory usage per terminal.
        - slight overall speed improvements.
        - considerably improved code clarity.
        - partial-screen scrolls no longer end up in the scrollback
          buffer.

5.9  Sat Dec 17 21:53:17 CET 2005
        - fix a bug in the menu code of unknown impact, found by darix.
        - clean up signal handling to be global, not per terminal
          (matters only for rxvtd).
        - fix small typoe in rxvt.1 (found by Mike Fabian).
        - don't crash when broken xft/fontconfig/freetype versions return
          bogus data, ignore the xft font instead (experienced on suse).

5.8  Tue Oct 25 22:21:45 CEST 2005
        - INCOMPATIBLE CHANGE: many configure options are now on by default.
          If you want the old behaviour, try:
          configure --disable-everything <your enable options>
        - INCOMPATIBLE CHANGE: -fade changed its meaning to comply with
          the documentation and common sense: when upgrading, replace your
          percentage by 100-percentage.
        - integrated "fade to specific colour" patch by Martin Parm.
        - slow down the internal visual bell (delay by 20ms) and update
          the terminfo flash code to use the same delay.  This is
          synchronous, so many bells might inhibit screen updates in other
          windows.
        - text with background==foreground colour gets displayed with default
          bg/fg now when in reverse video, so it can be seen when selecting.
        - allow koi8r* as x11 encoding name for koi8r (Nikita Danilov).
        - removed undocumented inheritPixmapforce option.
        - replaced INSTALL file.

5.7  Wed Jul 13 04:46:33 CEST 2005
        - implement some useful (hopefully) options for rxvtd.
        - separate and improved rxvtc(1) and rxvtd(1) manpages.
        - fix a bug that caused segfaults on startup on systems that do
          not support local unix connections, e.g cygwin. (btw, I didn't
          even know about the -rootless and -multiwindow Cygwin/X modes).
        - large amounts of text without control sequences or newlines
          could almost freeze output. This has been fixed by adding extra
          refreshes in these cases (also a problem in original rxvt).

5.6  Sun Jun 26 22:11:13 CEST 2005
        - R_SB_RXVT bitset value was 0, so rxvt scrollbar was initialised
          every time resulting in display errors (original rxvt also affected).
          Reported by Jasmin Buchert.
        - font names are now considered to be utf-8 encoded (xft apparently
          uses this convention. X Core fonts might not, but it should be rare).
          Affects display in iso14755 box.
        - rewrote the low-level xft drawing function ("xft backend" for the
          hipper parts of the world) to hopefully cope better with proportional
          chars mixed with fixed-width ones.
        - rxvt is now much more careful (read: slower) with potentially
          overlapping xft characters. It usually overshoots and redraws
          more than required, but that's better than undershooting and
          cutting pieces off of characters.
        - rxvt is now more restrictive in what font heights it accepts for
          fonts that will likely overshoot or undershoot lines.
        - fix a cosmetic problem with the unfocused cursor on a wide character
          at the end of the line (reported by Mikachu).
        - wide characters not fitting into the end of the line will be
          output in the next line (reported by Mikachu).
        - added doc/solaris9.patch by Ewgenij Starostin.

5.5  Sat Apr 23 22:31:36 CEST 2005
        - re-enabled modifier state matching as in 5.3, but implement
          a new builtin: keysym style that simply reverts to the built-in
          meaning of the given key.
        - use scrollcolor for next scrollbar instead of hardcoded antiquewhite
          (patch by Martin Edlman).

5.4  Mon Apr 18 00:33:31 CEST 2005
        - match modifier state exactly in custom keyboard code.
          this is necessary because it has no knowledge about
          built-in mappings and so will overwrite them. the priority-code
          will be re-enabled when this has changed, so watch out.
        - cursor blinking now depends on frills.
        - underline cursor mode (frills, -uc).
        - implement special value (*g*) for pointerBlankDelay
          to disable it.

5.3  Sun Mar 13 00:20:44 CET 2005
        - fix a bug that allowed to overflow a buffer via a long
          escape sequence, which is probably exploitable (fix by
          Rob Holland / Yoann Vandoorselaere / Gentoo Audit Team).
        - Custom key mappings no longer confuse mouse buttons
          with modifiers.
        - use XmbSetWMProperties instead of XSetWMProperties.
        - properly update WM_LOCALE.
        - implement _NET_WM_PING protocol.
        - implemented escape sequences to move the scrollback buffer view
          and clear the scrollback buffer.

5.2  Sun Feb 20 01:48:59 CET 2005
        - new option -pty-fd that makes the terminal a slave
          that uses an existing pty for I/O instead of starting
          a command.
        - implement enough of XEMBED to allow for correct focus.
        - added doc/embed-tk, an embedding example in Perl/Tk,
          and doc/rxvt-tabbed, a primitive tabbed shell implemented
          in Perl/Gtk2.
        - fix assertion failure ("crash") on mousewheel-scrolling
          when the terminal height is small, by removing the assert.
          (reported by Mikael Magnusson=Mikachu).
        - SYNCCVS. backported bugfixes done to rxvt
          (sourceforge bugs #1028739, #1028732), except for
          pts/%s fix as it seems to collide with freebsd,
          and sourceforge bug #954654, which is not necessary.
        - change terminfo file to not clobber G1 when using
          line-drawing characters, as this seems to mess
          with EUC-JP (it will clobber G0, but G0 practically
          needs to be US-ASCII all the time).
        - toggle default application keypad/cursor mode to help
          some apps who fail to set the correct mode.
        - check for WM_PROTOCOLS type in ClientMessage as to
          not destroy the window for other types of messages.
        - remove shared library (or any library) support - it is
          of no use currently (and -embed is a better way to embed
          rxvt-unicode).
        - get rid of the intpro files.

5.1  Tue Feb 15 17:13:27 CET 2005
        - fix a bug when parsing fontnames and another one
          for empty keymaps which could result in crashes
          (Kuang-che Wu).
        - new option: -embed (frills). somebody could write a simple
          tk script to make a tab'able terminal now...
        - only warn on X errors and _try_ to continue (frills).
        - add COPYING back, which got lost somehow.
        - after deciding that LSM is dead, remove all traces of it,
          along with other, similar, cleanups.
        - _try_ to react sensibly to some non-monotonic time changes.
        - don't crash in urxvtc when getcwd fails (reported by Paco-Paco).
        - tweak font searching algorithm a bit to be faster and more
          compatible with older rxvt-unicode versions when multiple fonts
          match (reported by Paco-Paco).
        - urxvtd tries to stay in "/" whenever possible.

5.0  Fri Feb 11 18:31:48 CET 2005
        - document a race-free hack to start urxvtd.
        - document all(?) environment variables used and set by rxvt.
        - bring xgetdefault-style resource file ordering more in line with
          Xt, and document it in rxvt(1).
        - correctly use screen-dependent resources when --enable-xgetdefault,
          and also fix some memory bugs (thanks to Thierry Reding for
          his patience and time in tracking this down).
        - bring own resource parsing more in line with X resource parsing,
          most notably, don't remove double quotes.
        - compile fix for freebsd (no ut_id) (Thierry Thomas).
        - clean up utmp and pty on X I/O errors and signals (idea
          by Joël Riou).
        - "un"document -xrm, it never really worked, was only
          available with --enable-xgetdefault, is not necessary
          and is surprisingly hard to implement.
        - shaved off some code segment size.
        - various code cleanups.
        - more keysym-mapping fixes.

4.9  Thu Feb  3 09:52:03 CET 2005
        - nuke out utmp entries completely. Should be fixed in
          original rxvt, too. (reported by James Michael Fultz).
        - resizes will now correctly refresh the displayed text when
          -pixmap is active.
        - new option/resource imFont.
        - document --tripleclickwords/-tcw.
        - select logical instead of physical lines when doing a triple-click.
        - reordered help listing to group similar options together.
        - handle SIGINT the same way as SIGTERM (reported by Joël Riou).
        - fix a bug introduced while applying the keyboard patch
          (WU Fengguang).
        - document all window-op sequences (rxvt.7.) and more keysym
          examples (rxvt.1).
        - removed src/test completely.
        - renamed keysym 'proto:'-prefix to 'command:'.

4.8  Tue Jan 18 02:23:57 CET 2005
        - added a patch by WU Fengguang that makes the keyboard
          highly configurable (e.g. locale changes, custom escape
          sequences, and more). See keysym resource in rxvt(1).
        - remove default key sequence for unknown keys again, as this
          can be achieved by customizing the keyboard now.
        - fix some freeing problems when destroying the rxvt_display,
          resulting in segfaults.
        - don't crash when the saved cursor position doesn't fit on the
          screen (wrong assert in original rxvt, reported by ikaro).
        - fix signed/unsigned bugs on wc<->mb conversions.
        - reset slipwheel scrolling speed when reaching the top or bottom
          (Mikael Magnusson).
        - for core fonts, use ascent + descent when a font is loaded,
          and PIXEL_SIZE when not. when loading a font, iterate until a
          font has been found that _really_ fits the height (reported and
          tested by Olivier Wittenberg).
        - set IUTF8 input flag, when defined (linux-2.6.5+).
        - only define _XOPEN_SOURCE on solaris.
        - autogenerate src/* dependency list.
        - fixed linespace option, which ought to work now (and is dependent
          on frills, not on its own configure option).
        - include pty.h, if available (cygwin).
        - removed W11 directory from dist, it wasn't used anyway.
        - initialize the locale much earlier.
        - fixed two tiny per-instance memory leaks.

4.7  Wed Dec 29 20:54:24 CET 2004
        - fix a bug in the event logic that could cause the terminal to be
          black on initial startup.
        - do NOT call XCloseIM, ever. This causes way to many crashes due to
          races in the protocol and within Xlib.
        - map iso-left-tab to the same sequence as shift-tab.
        - generate a unique escape sequence for many unknown keys, such as
          additional multimedia keys.
        - mask out high (non-unicode) bits on wide characters, to cope with
          implementations that store tag info in the high bits.

4.6  Thu Dec 16 07:54:23 CET 2004
        - try very hard not to exhaust the kernel tty buffers, even
          if it slows down large pastes and is only cosmetic.
        - streamline atom and xft color allocation to reduce startup
          time (12.8s -> 7.8s on my dsl). Still, doing it with only 2-3
          turnarounds would be much faster, but impossible to implement(?).
        - implement underlineColor resource when ENABLE_FRILLS.
        - iom left its signal pipe handle open in the child
          process. Fortunately not security-relevant as the pipe data gets
          ignored.
        - do not use XSETROOTPMAP_ID anymore, support ESETROOT_PMAP_ID
          instead.
        - fix a crash in rxvtd when the last window was being closed
          (reported by hednod).
        - fix an unlikely memory leak.
        - fix atom name enumeration.

4.5  Mon Dec 13 07:47:16 CET 2004
        - fix an extremely nasty bug in utf8-conversion. upgrade is advised.
        - completely re-wrote selection pasting. This should fix garbled
          incomplete characters at 32k boundaries and too-short INCR
          selections, and more. Increases memory requirements considerably
          for large selections, but that seems unavoidable.

4.4  Sun Dec 12 22:10:06 CET 2004
        - rewrote handling of default-char width.
        - implement _NET_WM_NAME et al., and also use UTF8_STRING
          for the xterm property esc. sequence. Allows i18n window
          titles etc.
        - SMART_WINDOW_TITLE removed, pls. complain if you need this.
        - added GBK encoding (formidable patch by WU Fengguang).
        - fixed a bug in the transparency code.
        - upgraded iom.[Ch].
        - force slower (but more responsive) transparency update.
        - fix off-by-one bug with wide characters at the end of a line,
          which got partially overwritten by spaces.
        - as xlib is completely broken with respect to utf-8 handling
          and nobody is going to fix it, that part has been re-implemented.
          should fix most paste problems between apps that use UTF8 encoding
          and rxvt running in a lesser-supported locale (thanks to Robin Redeker
          for writing utf8towcs). Only enabled with ENABLE_FRILLS.
        - darwin compile fix by Ethan Blanton.
        - fix the colour of the underline, which was rather random before.

4.3  Sat Dec  4 04:58:37 CET 2004
        - unapply the "emulated graphical chars. respect wcwidth" patch.
          obviously in locales not having these characters they should
          still have a width. Solve it correctly by not relying on wcwidth.
          Note to self: do not ever apply patches without checking them
          thoroughly.
        - updated .spec file, it's included in the release tarball
          now, too.

4.2  Wed Dec  1 03:30:22 CET 2004
        - make emulated graphical characters respect wcwidth (Kuang-che Wu).
        - remove debugging code that caused major slowdowns
          on high-latency networks.
        - wide characters shift the correct number of characters
          in insert mode now. Reported by Gunnar Ritter.
        - doc/rxvt-unicode.spec file contributed by Ville Herva.
        - make storage of tab movements as characters optional
          on the -ptab option and pastableTabs: resource. On request
          by Gunnar Ritter.
        - fix a bug where :size= argument for xft fonts was ignored
          or used incorrectly. Reported by Ville Herva.

4.1  Sun Nov 21 21:10:19 CET 2004
        - save and restore cursor position in secondary screen regardless of
          -ssc/-ssr settings.
        - fix some 64-bit bugs that lead to crashes with certain other
          programs like vncviewer (original rxvt also affected).
        - added doc/podtbl to the dist tarball.
        - add compile fix for darwin.
        - configure fix for transparency without tinting.
        - changed CN to ZH _really_ everywhere.
        - upgraded iom.[Ch].

4.0  Mon Sep 13 01:10:26 CEST 2004
        - turn off autohinting for some badly-hinted fallback fonts.
        - mnaapge tpyo crorcetoins by Bastian Kleineidam.
        - implemented rectangular selections (button+meta), experimental.
        - implement race-free signal handling in iom.C.
        - use iom.C signal handling to avoid races in signal handling.
        - use default action on SIGINT and SIGQUIT, instead of terminating.
        - "the return of the 100 times per second refresh bug".
          ... terminated by a fix.
        - new supported preeeditType "None".
        - added FAQ about possible compose key problems.
        - changed CN to ZH everywhere (sorry for the confusion).
        - move XFilterEvent up, as some input method seem to want events
          for windows not requesting XIM. Please report if this change
          causes any harm (specially with pointerblanking)
          (patch by Kuang-che Wu).
        - send the input method spot position on every refresh, not just
          when rxvt thinks it should (which was not often enough...).
        - fix double-wide combining characters (it might look a bit ugly,
          though, but common cases are handled by normalization anyways).
        - moved FAQ to rxvt(7), also made a copy into README.FAQ.
        - fix a bug(?) in the XIM destroy callback.
        - be more conservative when trying to register new input methods,
          as Xlib races might make rxvt crash. When two or more
          input methods are active, killing one probably still crashes rxvt
          due to that bug :( Thanks a lot to Kuang-che Wu for immense help
          in tracking this down.
        - manpages (but not .txt and .html versions) will be patched (during
          make install) with the correct program name and other info.

3.9  Wed Aug 25 19:24:04 CEST 2004
        - the change to unsigned int from unsigned short broke
          many signed comparisons, resulting in failed assertions.

3.8  Wed Aug 25 05:46:56 CEST 2004
        - WARNING: TERM=rxvt-unicode is now *default* unless compiled
          differently. A terminfo entry will automatically be compiled and
          installed if tic is available.
        - fixed some --disable switches that didn't work.
        - tweaked src/features.h a bit.
        - removed README.unicode.
        - support select&paste of tab characters.
        - fixed a segfault when trying to load nonexistent fonts (reported
          by Eduard Bloch and Mikael Magnusson).
        - fixed a long-standing rxvt bug in which rxvt failed to save
          and restore the correct cursor position on the secondary screen.
        - reworked rxvt-unicode terminfo to allow more efficient and less flickering
          screen updates with curses.
        - wide characters that are being halfway overwritten are now replaced
          by spaces.
        - urxvtc now transmits urxvt as default name, not urxvtc anymore
          (likewise for other names chosen at configure time).
        - disabled the automatic font lookup for unknown characters. xft
          is just too slow for this to work.
        - changed realbold code, implemented _real_ bold and italic support,
          where _real_ means the symbiosis of what I want with what I can
          implement. use --enable-styles.
        - removed 256 color mode, but enable 88 colours in all modes
          (88 to be compatible with 88 colour xterm which is widely
          supported, and most programs assume a non-iso colourtable
          for terminals with "odd" number of colours).
        - added doc/etc/rxvt-unicode.terminfo which is a big overhaul
          compared to the old rxvt terminfo.
        - sped up xft rendering by 30% *iff* the font allows it (i.e. is
          monospaced "enough") *and* matches the base font in width.
        - implement positive and negative character-font caching, which
          speeds up output immensely in case a character cannot be found
          (only for non-bold right now).
        - fix segfault in fading code on certain escape sequences.
        - better default font size and style.
        - rxvt-unicode is now much more picky about fonts not fitting
          into the base font, but to offset this it will check each
          single character against the base font extents and will only
          use the characters fitting into the bounding box (+ some fudge).
        - characters not fitting into the base boundary box will now often
          be used anyways, but the following characters will be redrawn
          more often to avoid pixel-droppings. This is like the original
          rxvt pixel-dropping pass but it's much faster.
        - scrollColor now affects plain scrollbar (Mikael Magnusson).
        - fixed segfault in overlay code when height was larger than the
          screen height.
        - cursor no longer shines "through" the overlay.
        - 7-bit ST marker detection was broken.
        - scrollbar didn't come back sometimes when switching it
          off/on using escape sequences (Mikael Magnusson).
        - fix lots of colour problems with focus fading.
        - $COLORFGBG was not set as documented.
        - fix iso 14755 5.1 support when --enable-frills but --disable-iso14755.
        - removed OSC 702.
        - disabled MOUSE_REPORT_DOUBLECLICK by default, as programs seem to be
          confused by it rather than using it.

3.7  Tue Aug 17 04:22:25 CEST 2004
        - new configure option --enable-iso14755.
        - full iso 14755 conformance (at least I claim so :).
        - extended the FAQ section in the manpage.
        - fix OverTheSpot and OffTheSpot editing, which was broken since ages,
          due to no fontset being available. The fontset used is a very rough
          approximation to the rxvt font, though. This fixes the
          "cannot create input context" in most cases.
        - fix coordinates used for Over && OffTheSpot editing to fit directly
          at the cursor (Over) or into the top line (Off).
        - reset SIGHUP and SIGPIPE handlers to default values (they were
          previously being ignored, causing programs not to exit on window
          close).
        - implemented simple overlays for feedback messages. believe it or
          not, this was a major blocker in implementing tabbed terminals.
        - fix compiling with --disable-frills (Adam Sampson).
        - clarify bold docs in README.unicode (Adam Sampson).
        - fix crash on window close when the input method or context
          could not be created.
        - add work around for badly written programs (see debian bug
          #202497). This is _not_ a bug in rxvt but rather a race
          condition in other programs (e.g. jed). It works by forcefully
          sending SIGWINCH when rxvt sees the first output from the
          command. This workaround isn't perfect (a slight cost to
          wellbehaving programs who need to resize twice), but it usually
          works.
        - set correct pixel size in struct winsize.
        - document more escape sequences.
        - fix leftover macros and a few minor doc glitches in rxvt(1).
        - work around bash's assumption that stepping into the middle of a
          character is a sensible operation.
        - fix some corner cases in autowrap handling.
        - remove various useless make cruft, renamed files to better
          reflect on their function, renamed many variables.
        - fixed printscreen functionality, as noted by Jinesh Choksi.
        - fix a problem where redraws of double-width characters sometimes
          made the last character draw with normal width (especially visible
          with selections).

3.6  Sat Aug 14 04:55:26 CEST 2004
        - SECURITY FIX: rxvtd kept open filehandles to other terminal
          windows when spawning children. Actual risk is low (attacker
          needs access to a local shell window).
        - implemented parts 5.1 and 5.2 of ISO 14755 (i.e. hold down
          Ctrl+Shift and enter hex numbers. space commits it as a unicode
          character, or press and release Crl+Shift and then enter a
          function key to get its picture). patches for 5.3 (or 5.4 with
          a little window or so) would be welcome.
        - fixed large pastes (INCR selections, debian bug #191456).
        - fixed longstanding bug in which rxvtd crashed when
          a message was logged after startup (a rare case).
        - got rid of yodl completely by converting to pod.
        - integrated the FAQ into the manpage. In the future, more will be
          added there.
        - reference documentation is now installed as rxvt(7).
        - rxvt(7) now contains README.configure, which is autogenerated.
        - fix memory leak in insecure mode on certain display echos.
        - report sequences now report empty strings in secure mode
          instead of being ignored.
        - enable some report sequences even in secure mode, such as colour
          queries, as they are harmless(tm).
        - rxvt-unicode will now try to find a matching xft font if it can't
          find a matching font from the fallback list. It might look ugly,
          but if a xft font with our character exists, rxvt will find it.
        - moved FreeMono to the very back of the fallback list, as some
          people complain it looks ugly. This is a no-win situation, though.
        - fixed sourceforge bug 998970, reported against aterm:
          "crash on -sl 0 on super small windows".
        - decreased memory and code size when !--enable-transparency.
        - SYNCCVS. backported changes done to rxvt, except for Color_ufbg,
          which I think is better done through fading, and libW11, which
          needs testing anyways.
          - more complete compile options help output.
          - Provide linear scaled colour cubes for 256 colour mode.
            Pass them through as rgbi rather than rgb so that Xlib can
            provide gamma (from per visual intensity lists) rather than
            providing constant gamma ourselves.  Noticed by and ideas from
            Christopher Casey <realchriscasey@hotmail.com>
          - minor doc fix.

3.5  Wed Aug 11 00:31:34 CEST 2004
        - UPGRADE ADVISED: rxvt did wake up 100 times per second. did not
          show in my top (linux...), but it's extremely annoying that I
          released it with that bug. :( Fixed.
        - use memove instead of for-loop for large scrollback buffer copies.
          speeds up large scrollback buffers (on systems with reasonable
          memmove :)
        - minor cleanups.
        - removed ~ from default cutchars, in accordance with the manpage
          (debian bug #169415).
        - fix a race condition on exit (debian bug #197265).
        - change prio/next scrolling modifier handling (debian bug #226386).
        - updated configure script to current autoconf standards.
        - updated config.guess.

3.4  Fri Aug  6 19:34:29 CEST 2004
        - fix inheritpixmap transparency border code.
        - fix tinting transparency border code, also experimentally
          make some scrollbars transparent (e.g. plain, my favourite style :).
        - imported aterm shading code (faster and still portable).
        - changed interpretation and usage of shading (-sh).
        - fixed blinking underlined and negative text.
        - disable slow link support on connections using unix domain sockets,
          speeding up scrolling immensely.
        - various other optimizations.
        - new borderLess switch (ewmh-compliant), by Mikael Magnusson.

3.3  Sat Jul 31 15:15:59 CEST 2004
        - some doc updates (Eduard Bloch).
        - use faster inheritpixmap method when tinting color not set.
        - fix pixmap offset when tinting (reported by Eduard Bloch).
        - new -sh option by Mikael Magnusson.
        - off-focus-fading (--enable-fading) support (patch by
          Mikael Magnusson, based on aterm code).
        - cursor now set correctly on --disable-blank (reported by
          Mikael Magnusson).
        - better (and non-crashing) slipwheeling (Mikael Magnusson).
        - solaris 2.8 portability changes (reported by Colin Marquardt).
        - disable-xim now really disables xim code.

3.2  Mon Jul 26 19:57:32 CEST 2004
        - support real bold fonts (patch by Adam Sampson <azz@us-lot.org>),
          if specified in the font list (and enabled by -rb).
        - fixed --enable-keepscrolling and --enable-selectionscrolling, which
          was broken since 1.8. Patch by Hans de Goede <j.w.r.degoede@hhs.nl>.
        - fixed --enable-slipwheeling, see above.
        - sequences ended by ST can now contain any octet by quoting it
          with ^V (SYN).
        - 8-bit-controls disabled by default (compiletime option).

3.1  Sat Jun 26 23:38:07 CEST 2004
        - set default backspace sequence to "DEC" (which defaults to \177)
          as opposed to \010 as before, which was incorrect (ahem :).
        - updated doc/etc/rxvt.* to reflect the change. This brings rxvt
          in line with many existing rxvt terminfo and termcap entries as
          well as with other terminal emulators.
        - fix a segfault when trying to set a nonexistent locale
          (reported by elmex).
        - find more fonts by default for japanese.
        - the internal border wasn't always cleared. This is fixed by moving
          the window relative to its frame and simplifies a lot of code, too.
        - fixed quite hard to find scrollbar colour bug, reported by Eduard
          Bloch.

3.0  Mon May 10 20:47:23 CEST 2004
        - experimental flickerfree resize mode (I tried to get even
          less flickering with SouthWestGravity but couldn't get it to work,
          sorry).
        - c++-ify (or at least make it compile with g++-3.4, which should
          make it a little bit more correct c++).

2.9  Sat May  8 19:13:41 CEST 2004
        - fix some minor doc issues + some generated doc files are now
          getting distributed (closes debian bug #246035).
        - minor i18n issue fixes.

2.8  Thu Apr  8 22:44:36 CEST 2004
        - replace PF_LOCAL by PF_UNIX (portability).
        - try to detect -lnsl and -lsocket (portability).
        - fix some minor bugs.

2.7  Mon Apr  5 02:11:15 CEST 2004
        - this version should now work fine with TERM=xterm, except
          for the keymappings.
        - don't leave the X or rxvtd sockets open in child processes.
          (inherited fd's stay open - different to rxvt).
        - xterm-compat: implemented OSC3, set/get window property. get is
          an extension and is slightly ugly.
        - removed --disable-swapscreen and SCROLL_ON_NO_SECONDARY and
          replaced them by runtime-configurable options secondaryScreen and
          secondaryScroll (-ssr and -ssc) (see debian bug #237673).
        - close down terminal window when child exits. (debian bug #241267).
        - xterm-compat: enable separate mouse bg colour setting.
        - re-enable mouse cursor colours again, fixing colours when fg/bg are
          overwritten (as is common).
        - xterm-compat: correctly implement privmodes 1047, 1048, 1049.
        - ported to solaris by elmar@math.uni-bremen.de.

2.6  Fri Apr  2 03:24:10 CEST 2004
        - minor doc corrections.
        - WARNING: changed menu sequence from ESC ] 10 to ESC ] 703 to
          avoid clashes with xterm.
        - changed OSC701/OSC702 sequence to return standard escaped reports.
        - xterm-compat: make set window colour and other requests report
          window colour when arg is "?".
        - enable colour tinting of "transparent" backgrounds.
        - stop ST sequences earlier, as we now react on 0x90 and thus
          cause conditions more often that look like locks but are, in
          fact, just rxvt waiting for a ST/BEL etc.
        - re-enabled most of the "dangerous" echo escapes, but only
          when -insecure is specified as option or resource (see reference).
          (FRILLS).
        - disables sleep(1) on transparency updates on default.
        - fixes to make it compile better on solaris 2.9 (at least).
          asprintf replacement is still missing(!).
        - set _NET_WM_PID.

2.5  Sun Mar 28 04:05:51 CEST 2004
        - the usual sprinkled little code cleanups.
        - support more 8-bit controls.
        - more informative error messages.
        - fix some minor memleaks and possible memory corruptions.
        - the use of exception handling allowed the following improvements:
        - no longer block when waiting for completion of escape sequences
          (e.g. printf '\e';sleep 3;printf 'c' will no longer block).
        - rxvtc usage errors should no longer kill rxvtd (debian bug #237510).

2.4  Tue Mar 16 07:06:51 CET 2004
        - fix stupid double-free() bug on exit.
        - implement xterm private mode 1049.
        - fix manpages (debian bug #236824).
        - removed old selection style completely.
        - selection works _better_ for non-8-bit and double-width chars.
        - remove native->unicode translation tables. they aren't used anymore.
          reduces binary and distro size a bit.
        - add string representation for JIS X 0213:2000 so these fonts can
          be used from within rxvt.
        - less buggy complete set of line-drawing-characters (0x2500-0x259f).

2.3  Sun Mar 14 19:00:07 CET 2004
        - code cleanup release.
        - fix compile problems without --enable-combining.
        - fix segfault when DISPLAY cannot be opened.
        - removed HOTKEY_CTRL and HOTKEY_SHIFT, ACS_*, FONT0_IDX,
          MAX_NFONTS. UNICODE and UTF8 defines and references from
          all files.
        - default config now reads an app-defaults file even without
          --enable-xgetdefault.

2.2  Thu Mar 11 01:41:56 CET 2004
        - implement autocompositing of characters by either using an existing
          precomposed unicode character or by graphical overlay. this is
          also used to store characters >16bit without --enable-unicode3.
        - selection now based on wchar_t, so that it can offer UTF-8
          selections even in locales unable to represent full unicode.
        - tis620-2529 is, of course, thai, not vietnamese...
        - a typoe prevented characters >65535 to be stored properly.
        - wcwidth is unreliable in non-unicode-locales on GNU/Linux.
          working around this fixes line-drawing characters in non-utf-8 mode.
        - improved rounding when emulating line-drawing characters.
        - implement continuation lines in xresource parsing when
          --disable-xgetdefault.
        - changed locale-setting esc-sequence from code 9 to code 701.
          also added 702 that returns the font selected for a specific
          unicode character.
        - no longer set CUT_BUFFER0. this is confusing and clients WILL
          get it wrong.
        - don't use XTextStyle for TEXT, instead use XStdICCTextStyle.

2.1  Wed Mar  3 21:48:39 CET 2004
        - NOTE: the name of the binary and resources were changed in
          this version, see README.configure if you want the old
          settings.
        - added plain "big5" encoding into CN.
        - make cns11643 and big5* encodings actually visible to rxvt.
        - fix a bug when a multibyte character fell onto a buffer boundary,
          causing the incomplete character to be presented twice to
          mbrtowc.
        - more robust encoding name matching.
        - fix cursor placement on multibyte characters.
        - when overwriting wide with narrow chars, pad with spaces.
        - fix various refresh and display issues for wide chars.
        - remove multibyte_cursor hack (it was a hack) and associated
          resources and docs.
        - fixed memory corruption bug with XLFD fontname parsing.

2.0  Sun Feb 29 23:59:58 CET 2004
        - do not blink text when background colour is not set explicitly.
        - some doc cleanup
        - configure cleanup
        - viscii enabled by default
        - better support for non-g++-3.2+ systems (tested with g++-2.95).

1.91 Fri Feb 27 03:57:44 CET 2004
        - build fixes for !xft and !im, reported by various people.

1.9  Wed Feb 25 16:46:05 CET 2004
        - fixed bug in plain scrollbar causing X errors in XCreateGC.
        - implemented sharing of X connections. will be used to speed
          up many x operations considerably. Also saves some memory.
        - implemented caching of input methods. This immensely shortens
          startup time for new terms in rxvtd. At least XFree86 4.3 is
          rather broken with respect to input methods, though, so expect
          crashes when you kill your input method (xterm et al. also crash).
        - fix bugs in X flushing, causing an empty screen after startup.
        - fix various memleaks in rxvtd.
        - fix a bug that kept escape codes to be generated for some
          keysyms that also have string translations, when not --enable-xim.
          reported by joel reed.
        - re-enabled esc-seq. for font-switching (\033 ] 50 ; <fontset> \007).
        - re-enabled menubar (experimental!).
        - fix bug in locale-handling that kept the correct locale from
          being selected.
        - implemented esc-seq. to switch locales (\033 ] 9 ; <locale> \007).
        - removed greek support.
        - allow NUL bytes (ctrl-@) to be entered even with XIM enabled.
        - correct cursor width if !focus.
        - fixed --enable-xgetdefault, reported by eduard bloch.
        - added manpage for rxvtc/rxvtd based on the one eduard bloch
          contributed.
        - use reverse video for normal bold text unless colorBD has been set.
        - fixed endless loop when selection is valid but empty.
        - changed default terminal name to "rxvt".
        - many other minor bugfixes.

1.8  Mon Feb  2 20:09:18 CET 2004
        - almost total conversion to C++. Except for introducing
          new bugs, this should not change much.
        - fix and re-enable background pixmap and inherit pixmap support.
        - re-enabled multiple scrollbar support.
        - added plain scrollbar style and restored xterm scrollbar.
        - blinking and selections work slightly better now.
        - fix an error condition when rxvt receives more than one screenful
          of output. should occur with original rxvt, too, but very rarely.
          (I guess the code contains more surprises of this sort...)

1.7  Fri Jan 30 16:50:11 CET 2004
        - further cleanups.
        - never do last-minute-changes: restore ability to have
          color + bold as high-intensity, and let the selection
          use reverse video, not _blink_.
        - remove OPTION_HC, at least temporarily. If you want it back,
          please drop me a note.

1.6  Fri Jan 30 00:34:01 CET 2004
        - cleanups, minor bugfixes.
        - blinking text.
        - normal text color + bold gets white text instead of
          normal text when colorBD is not set.
        (- support double-wide characters (by blocking).)
          was never implemented

1.5  Thu Jan 29 00:43:48 CET 2004
        - share io manager between rxvt-unicode and vpe
        - bugfix for --disable-utmp, reported by fefe himself
        - colors were sometimes not used correctly because
          parts of the code expected a monochrome display.
          reported by fefe
        - make it compile without pointer_blank, reported by
          Markus Demleitner
        - improved selection support, now supports UTF8_STRING
          and properly encodes CUT_BUFFER0 in iso-8859-1
        - completely removed non-working graphics mode

1.4  Fri Jan 16 23:03:22 CET 2004
        - fix stupid segfault on esc-c
        - small font tunings
        - much better io manager, fewer bugs, higher speed
        - better error reporting for unknown options

1.3  2003-12-26
        - fix a bug in font height selection
        - autoscale scalable x11 fonts
        - slow-mode xft rendering centers characters
        - much faster x11 font selection

1.2  2003-12-24
        - fix another segfault-on-resize-bug from the original rxvt
        - better font matching
        - better memory management (less memory)
        - new fallback: gnu freefont

1.1  2003-12-18
        - Support for XIM in other than the current locale.
        - Support for non-utf-8-locales
        - much improved font choosing
