        - last remaining BUG (that showed up in the logs for the last years) has
          been fixed: monsters would snatch arrows/thrown_objs out of the air without
          stopping them, causing BUG: arrow had no map. Fixed by marking shot arrows,
          bolts and thrown objects as NO_PICK temporarily.
        - since binutils/gcc/etc. conspired to break static archives, converted the server
          binary build into non-recursive Makefiles without static archives. hell, automake
          is certainly not ready for non-recursive makes, what a hack :()
        - use c++11 headers in preference to tr1 ones.
        - fix odr violation: struct point.
        - make the code warnigns-clean, for some definition of warnings.
        - port to g++ 6.
        - implement keep_suffix meta for cfutil, so files keep their extension.

3.1  Wed Nov 16 23:17:11 CET 2016
        - convert to blitz++ 0.10 and later (also requiring c++ 11).
        - port to perl 5.18 and newer.
        - switch to xz compressed archives as only dist method.
        - upgrade to automake 1.15.
        - (maps) hopefully fix tobias' tower.
        - (maps) hopefully fix healing potion vendor in arena entrance.
        - (arch) fixed an error in the Gnarg scale mail artifact.
        - it was possible to unapply or half-unapply cursed items in many
          cases, which confused players and also player state. fixed.
        - (arch) remove curse now works more liek idnetify in that it uncurses
          some items. also, no longer uncurses spells or other invisibles.
        - (arch) remove curse and identify now treta the marked tiem first.
        - creators no longer identify objects that shouldn't be identified
          (such as money, which won't stack afterwards).
        - (maps) the shady rogue in goths can unapply cursed items for you.
        - (maps) implement a wilderness town portal.
        - (arch) set proper(?) int values for all monsters.
        - (maps) fire5.map could destroy players.
        - (maps) fix pet arena pit/arena entrace and exits.
        - clear the spell's applied flag when inscribing scrolls, to make the
          scrolls mergeable.
        - redo all build material faces from scratch.
        - dropall without arguments now drops all containers.
        - use blitz++ for vector maths (new dependency).
        - only match archetype names in artifact allowed names.
        - new command "bumpmsg" that triggers the bump-into-wall messages.
        - altars with match expressions did not work properly.
        - use last_sp not cursed/damned flags in remove_curse/damnation spells.
        - god enemy race check fixed ("god detests your race").
        - gods errornously allowed any kind of worshipping race, even
          ones they hate.
        - use same default config in code as on gameserver.deliantra.net.
        - Pod::POM 0.26 and higher actually interpret =encoding, which broke
          our parser.
        - generate slightly more special exits and avoid warning.
        - applying a glowing crystal now gives status messages.
        - fix a memleak in the random map generator.
        - rework the random map parameter passign a bit to be extendable.
        - (random maps) use a nonrecursive algorithm to generate mazes,
          also, improve the quality of the mazes (no longer will the edges
          almost always form a passage) and add two new types - "rooms"
          and "braided".
        - implement --unique option to reset command.
        - (random maps) add new "cave" layout, which is much more ...
          cave-like.
        - (random maps) new layout style "castle" that generates straighish,
          rogue-ish maps.
        - (random maps) new layout style "multiple" that simply mixes multiple
          different styles in different areas.
        - roguelike maps sometimes had dead ends due to symmetry settings.
        - rewrite layout management in the random map generator from the
          ground up.
        - fix bug in tausworthe rng initialisation.
        - switched to the faster and hopefully better quality gfsr{24,55} random
          number generator, the same algorithm that freeciv apparently uses.
        - replace unreachable walls in random maps by "blocked", which saves
          memory and imho looks nicer.
        - (arch) fix samhlaidh archetype.
        - fix the "archname" match special function.
        - add kensler ("better gradient noise") functins, as well as fBm
          and other fractal algorithms.
        - one can no longer emote to logged-out players.
        - (maps) /pup_land/nurnberg/storehouse quest was fixed, the potatoe
          sacks fit on a tile again.
        - (arch) fixed message of improve wisdom scroll.
        - (arch) move glyph/magicmap/visibility into .faceinfo files,
          support background colour for text clients.
        - (arch) improve automatic name from archname generation.
        - implement faceset 2, colour + utf-8 glyph, for text-based clients.
        - support resist_xxx, body_xxx_info and body_xxx_used specials in
          match expressions.
        - don't cause an error if a monster tries to cast magic mapping.
        - sometimes a special exit wasn't placed when it should have been.
        - make newmapcmd mandatory, remove support for map0/map1.
        - require EV 4.00.
        - made wording of "use_skill jeweler analyze" a bit more precise.
        - add perlxsi.c to cleanfiles.
        - (arch) made speed potions easier for now.
        - the server didn't properly initialise all client skill slots,
          no known impact.
        - clean up unused settings, introduce DELIANTRA_DATADIR.
        - (arch) added potion of fortitude to resist fear for the jeweler skill.
        - (arch, maps) move worldmap gridmap data to arch/res/ and implement
          a generic table/matrix/palette converter to cfutil.
        - avoid crash in describe_item when a power crystal has maxsp=0 (as used,
          apparently, in the brewery map).
        - do not endlessly loop when an optional extension cannot be loaded.
        - remove limits of 000..999 from worldmap coordinates, support negative
          coordinates and introduce z-layers - deliantra is now 3d, in yet another
          sense.
        - move "the worldmap" to ext/map-world-classic.ext and make ext/map-world.ext
          handle generic "world map areas".
        - dropped micrpather again - we'll do our own implementation when we need it.
        - added is_quad flag.
        - (arch) added quad archetypes.
        - made the pickaxe mining tool remove quad walls and floors.
        - move key_values into their own class, simplifiying lots of code and
          making it possible to use kv pairs easily for maps and other objects as well.
        - get rid of get_archetype, finally.
        - maps no longer get activated when loading, only when a palyer is "near" them.
        - maps can now be swapped (not loaded), active and inactive, other states
          have been removed, and the map "intelligently" changes between active/inactive.
        - new variable $cf::SERVER_TICK, also rename pticks in C++ to server_tick.
        - remove legacy fly_on/off, flying, walk_on/off and no_pass attributes.
        - server now enforces width/height matches between tiled maps.
        - fix some off-by-one bugs that presumably created empty rectangles
          for unordered map walks - which should not cause any real issues.
        - increase face hashlen to 5 octets from 4, to avoid a collision.
        - fix output-rate limiting - min/max now use the first argument for the type,
          as all other similar macros - might cause other breakage...
        - cfutil no longer creates split tiles multiple times due to a
          off-by-one bug in comparing mtimes.
        - cfutil now supports type: prefix to derive faces from other faces, which
          is used for all build materials currently.
        - require imagemagick >= 6.6.
        - fixed possible crash due to broken initialisation order of shstr and
          freed_map, thanks go to Jonathan Neuschäfer for spotting this!
        - fix the brace command.
        - implement refcnt_buf.
        - avoid std::string to store facedata, use refcnt_buf instead, for a 20kb
          codesize decrease. wow.
        - removed version 1 ext/exti command support.
        - store meta information in faceinfo->meta unless prepended or empty.
        - new extension, ota_update, for online updates of the game client.
        - implement a simpler config value system for extensions that allows
          config updates without a reload.
        - fix a segfault in reload_perl due to perl 5.12's gv management changes.
        - make pick_lock work over map boundaries, and fix a crash while we are
          at it.
        - make nekosan more disease-resistant.
        - new event "infect".
        - setup protocol packet now supports JSONOBJECT syntax.
        - implement simple web server, currently to serve facedata for the html5
          client.
        - sort faces by name in the server to improve caching locality in clients.
        - actually prune face checksums (exp_table's checksum was too long).
        - add skill_info and spell_paths resources to enable caching the info
          and removing another command.
        - send completion info to the client.
        - assume all clients support the deliantra protocol extensions and allow
          fxix/extcmd and other protocol "extensions" before setup.
        - implement flash-policy-file server on server socket, to allow flash clients
          to connect.
        - implement exti doclet request to request documentation,
          currently for commands only.
        - created nickmon extension to monitor nicks.
        - ix now keeps a copy of the face data while sending, in case the
          face changes.
        - do not allocate memory for empty refcnt_bufs.
        - when faces change, invalidate all clients, not just clients with matching
          faceset, as faceset only applies to tile resources.
        - remove dependency on Time::HiRes.
        - move face data to disk, and load it on each and every access. this saves
          250mb ram on load, and 130mb ram in general, and only reduces the http
          server hot cache throughput for faces from ~24000 to ~18000 requests/s
          on my system. this should make it possible to add a lot more media files
          in the future, and reduces the memory footprint by the server from 180mb
          to 60mb ram.
        - create food/missile will now fail when the mapspace limits are exceeded.
        - pod processing could deadlock because the child process might try
          to get a lock.
        - removed support for ncom packets.
        - remove drawinfo packets from the server (use msg instead).
        - skill objects now have their documentation in the msg slot.
        - no longer allow prefix match when matchign spells, spells names must
          now be written fully.
        - avoid a deadlock when the incloader is called to load an in-memory
          file in a child process.
        - implement spellmon v2 protocol - no spell message.
        - remove ability to cats/invoke seplls by "count".
        - the "may" mechanism now supports uuids ina ddition to nicknames.
        - implement dm/dmhide in terms of the "may" mechanism, so dm
          players must now be configured by adding may_command_dm: ["uuid..."]
          to the config.
        - remove nowiz command.
        - change dm hiding - hidden status is no longer respected by spells etc.,
          it only affects information commands. use observe instead.
        - automatically send fx for all changed faces, not just for visible tiles.
        - fix g++-4.7/c++ incompatibilities in noise.h, and work around similar
          problems in blitz++.
        - catch sigfpe in the same way as sigsegv.

3.0  Sat May 29 23:30:57 CEST 2010
        - (maps, arch) complete revamping of the transport routes - all cities are
          now easily reachable, at a price.
        - (maps) the mana fountain now has a ratelimit of 30 potions per hour.
        - (maps) added (navar) gravedigger, that buys players gravestones.
        - (maps) added the rathouse quest for the shockwave spell in navar
          (by Dustfinger).
        - (maps) fixed bad floor tile in navar apartment.
        - made (wizard) look_at show also uuids.
        - added cf::object::find_object_uuid (::find_object already exists!).
        - (maps) added new apartment, made by LinuxLemoner.
        - (maps) added quest for the mining skill scroll to valleynoy.
        - (maps) added greedy highlevel book shop to heaven town.
        - (arch) added sounds: zombie death, book reading, inscription.
        - (arch) made the hill giants loose more body parts.
        - (arch, maps) added black unicorn horn, required to access mlab hell.
        - (arch) increased the (possible) number of arrows/bolts found in shops
          and made them a bit more expensive.
        - (maps) add more glory hole treasure styles.
        - (maps, arch) add "hollow" variants of cave\d tiles, and use them
          in a select number of mlab maps.
        - (maps) the library should be less of a death trap now.
        - (maps) exits no longer point to auto-apply exits, most affected
          maps now have proper doors or a similar solution.
        - (arch) jumping skill has now physical attacktype.
        - (maps) fixed nurnberg/reception/fire5 to match new style torches.
        - enter_map did not normalise the map coordinates when the destination
          space is blocked, causing badness and freezes for the player.
        - when applying containers, server checks for the key on activate
          and also allows players to unapply active containers they don't have
          a key for.
        - moved formulae, attackmess, artifacts, exp_table, materials and
          races files to arch, where they belong (exp_table is no longer in
          confdir but in datadir now!).
        - jeweler and sound config files are now normal datafiles as well.
        - quit_character was causing a runtime exception, causing it to not
          work since 2.93.
        - entering a map will now respect move_on and other effects,
          except for auto-apply exits :/
        - only talk to the items on the nearest mapspace, or, of there
          are none, to the player, not ALL items in vicinity.
        - do not update the floorbox while running, to avoid big item
          updates that cost network bandwidth and processing power.
        - diseases could reduce a monsters speed to MIN_ACTIVE_SPEED, which
          caused overflows causing monsters to become living deads.
        - unapply weapons and armour before trying to improve it.
        - teach the random map generator the ability to read ".rmg" files
          that specify which actual style map to generate, and use it for
          the default decorstyle to avoid inappropriate maps to be used.
        - support (with some limitations) multiple different skills with the
          same subtype.
        - fix "nekosan duplication" bug - map swap out was not atomic,
          so nekosan could end up beign saved AND escaped to another map.
        - show invisible no longer makes magic mouths visible.
        - move_type changes (spells, skills etc.) now will correctly
          take move_on/move_off into account (e.g. buttons).
        - display (exit) or (random map) in client for those objects.
        - removed (useless) spell damage columns from spell info and replace
          it by effective casting level - clients > 2.10 required to display
          properly.
        - building of levers/doors works again for all kinds of floors.
        - the player can now withdraw and deposit all the available money.
        - (maps) fix the apartment shop (japan => 吾妻) and add descriptions for
          steinwandstadt/celvear.
        - (maps) added /goodies map (goto *idkfa) with stuff useful for testing.
        - (arch,maps,code) rebalanced value of spellbooks greatly. it's now
          mostly based on the spell's level in the spellbook.
        - the music scheduler did not properly send new music on region
          changes.
        - (maps) fix some map regions and the region tree.
        - the server will now be more picky when parsing the regions file.
        - do not rely on chosen_skill in calc_alch_danger.
        - improve editor support protocol slightly, provide workarounds for 2.10
          clients.
        - follow has been rewritten to be, hopefully, more robust.
        - follow mode will not be aborted when the follower tries to move.
        - tcp.ext didn't unbind in reloads.
        - map-tags.ext didn't properly close the database on reloads.
        - cfutil skips .-directories when scanning.
        - build.ext prevents players from building on other player's maps.
        - rent.ext allows the dm to enter anytime.
        - NPC_Dialogue adds a new predefined variable, $map.
        - new "build" event hook.
        - get rid of archetype min/max values except max_x (which should go, too).
        - added fix_generated_item and cf::object::generate to XS interface.
        - no longer use uppercase identifiers for saving anywhere, but support
          them on loading, for old playerfiles and maps.
        - removed is_legal_2ways_exit - this is apparently dead code, and
          would be handled differently nowadays anyway.
        - random map .meta were not being expired at all.
        - replace move_ob/move_object functiony by the equivalent move method.
        - update to automake 1.10.
        - invitation to maps with unagressive and friendly monsters doesn't
          require level 4 anymore.
        - do not let update_stats muck with the chosen_skill anymore.
        - monsters now rotate through all skills (in chosen_skill).
        - fix lots of path-related buffer overflows in the random map generator.
        - detect/sense curse/magic will no longer work on items that don't
          need identify.
        - added detect mineral vein spell.
        - support "wall overlays" in the random map generator - not very generic,
          used by minable veins.
        - (maps) relocated jeweler town to another directoy.
        - (arch) implement mining pickaxes and mining skill.
        - (arch) add missing stonebig_club archetype from cfextended.
        - jeweler skill doesn't diminish input values anymore.
        - jeweler skill is harder to level now, but in exchange item power
          of the output is only 1/5th (instead of 1/3rd) of ring level.
        - jeweler skill adds the makers name (currently not visible) to the
          generated ring/amulet.
        - generate most constants for perl automatically.
        - properly check for weapon name prefix ("Ragnarok's sword").
        - when player dies, restore his food to at least 200.
        - support multiple inheritance for arch sources (inherit a,b,c).
        - switch to storable-n-format for facedata, for better interoperability.
        - implement generic "ranged" item framework (pickaxe, fishing rod).
        - the singing skill actually respects the direction now.
        - oratory and singing now require a direction.
        - use_skill now requires that you can actually apply the skill tool.
        - do not invoke perl on every user command anymore by providing
          a command and an unknown_command event.
        - move mark, run, run_stop, fire and fire_stop commands back from
          perl to C++, for speed reasons (basically undo patchset 1304).
        - add a client_destroy event, so we don't have to hook the
          attachable destroy event (which is called much more often).
        - removed (unused) FLOOR object type.
        - fix errornous change_abil messages for rods (and other types).
        - remove include/commands.h and server/c_new.C, and refactor
          all into server/commands.C.
        - save and restore combat/ranged/current slot for players.
        - the server now batches item's face/fx commands, as opposed
          to sending one fx per item - helps mostly at connect and
          with floorbox updates.
        - implemented ext::player_env::play_music_once $who->contr, "km/...".
        - the random map generator now supports selecting difficult for

        - support static scalar data members properly in genacc now.
        - implement "simple" freelist management for objects.
        - recycle object counts now - to support longer uptimes.
        - got rid of the dreaded write_parameters_to_string (666 chars omitted)

          "no relation to target" bugs.
        - try to load (pure-)perl modules asynchronously, warn about
          modules being loaded from the mainloop, pre-load some more
          core modules so perl doesn't do it later on.
        - pre-load many of the files perl might load on it's own e.g. when
          compiling regexes.
        - make exp_table and materials file reloadable.
        - made reload_config non-blocking.

        - (arch) considerably decrease slag ex price.
        - (arch) fix filth archetype.

        - extended the safe perl environment by loops.
        - (arch) fix "armless cook" facings.
        - the "experience table" resource item did not have a proper
          hash associated with it, so updates could not be detected.
        - fixed poison traps in doors.
        - player->killer_name did not properly flag the name as unicode.
        - aggressively mark many more methods as utf8 or octet-expecting,
          and provide a non-destructive SvPVutf8 variant.
        - do not allow dragon players to change their title via the settings.
        - ratelimited jeweler skill nugget conversion.
        - under high load, the server stopped swapping out to make
          the server more responsive, but making it impossible to reduce
          the load by... swapping out. slot queuing will now always make
          some progress.
        - improve the quality of the load-avg calculation.
        - (maps) fixed quest npc in jeweler dungeon quest.
        - don't fail to write the runtime file if the temporary already exists.
        - ipo.ext no longer uses (synchronous) CFDB, stores mail directly at
          player now.
        - rewrote hiscore code from scratch to use async I/O, store uuid and
          timestamp and use a tab in the client to increase awareness.
        - npc dialog setflag/setsatte now check for defined'ness, so
          setflag 0 is possible.
        - make install now deletes old extensions, to ease upgrades in the
          deliantra vm.

2.92 Thu Dec 24 04:51:56 CET 2009
        - the destruction spell could/would corrupt server memory quite often.
        - logging in only fixed the combat slot when the palyer was loaded from
          disk, not when it already was in memory.

          avoiding livelock during high-load emergency saves.
        - logging in did not properly unapply all skills.
        - (maps) make the invite quest marking much more obvious.

          to below MIN_ACTIVE_SPEED, deactivating the monster and causing
          much grief.
        - speed_left randomisation was, apparently, totally broken.
        - introduce FLAG_RANDOM_SPEED instead of using the sign bit
          of the speed slot internally and in map save files. among other
          things, this gets rid of all the abs (speed) calls.
        - reduce map file save files by using abridged keywords aliases.
        - shop specialisation calculation was totally broken.
        - nrof/itemcount/volume limits when dropping to the floor are

        - godgiven items will now be explicitly described as such.
        - (arch) dded a quiver of bolts.

        - balancing change, halve rod recharge speed (instead
          of 4.8s, the standard rods now recharge in ~10s. not a solution,
          but still.
        - reduce cpu time used for map saving by >>50% by avoiding
          the costly flag-checking loop in most cases and using a simple
          repeat-cache for speed_left.
        - always delay stats update for players on insert/remove till
          next tick/command, which saves a lot of cpu cycles on drop/take.

          have led to weird item multiplications.
        - store hash value in shstr, not used by anything, but doesn't use much memory.
        - fixed crash bug in learn_spell command.
        - enhanced output of the mapinfo command.
        - remove all traces of FLAG_NO_FIX_PLAYER.
        - avoid sv_derived_from calls (lots of hash lookups) when converting
          from perl to c++.
        - implemented least_significand_bit and for_all_bits_sparse_32 utilities
          and use it in some "inner" loops.
        - rename flags to attachable_flags to avoid confusion :=).
        - fixed jeweler experience output to not be floating point.

        - don't crash when a map uses empty sound/sound_destroy/face.
        - removed weather-specific attributes.
        - fixed genkeywords dependency.
        - do not clear "randomitems" slot for world underlays.
        - use "sl" as short-hand for speed_left in save-files, just to make them
          smaller.
        - in general, don't crash on value-less resource file lines
          anymore, due to get_str never returning a 0-pointer.
        - code cleanup in move_symptom.
        - removed arch_to_object (replaced it by ->instance ()).

2.90 Sat Nov  7 15:06:06 CET 2009
        - some Andrew Madloch wanted, despite being specifically told
          multiple times that the Deliantra parts additions are under AGPL,
          lock up the source code of the server within his company.
          some reorganisations have been done to the sourcecode to make
          it clearer that this violates the Affero GPL. Help to keep
          Deliantra free software even for the coming generations
          and be wary of the promises of Andrew Madloch, he has nothing
          good in mind for free software.

          not stats etc.).
        - replace magic mapping overlay by a flying bird exposing area
          on the worldmap (ext/magic_mapping.ext).

          dm instead.
        - (maps) add town portal to celvear.
        - (maps, arch) add troll canyon, pygmy forest, elven moon and temple of justice
          mapsets from crossfire, together with associated archetypes.
        - (maps) add extended region descriptions for some regions from crossfire.
        - (maps) define a new whalingoutpost region.
        - (maps, arch) add all changes to mlab between 2006-08-01 and 2009-10-28,
          and most archetypes that go with them (without stoning and swallow effects),
          casino tokens and stock certificates are also missing.
        - (maps, arch) add a number of minor maps from crossfire to scorn, navar
          and santo dominion.
        - (maps, arch) added gotischerbereich from cfextended, and some archetypes

        - doors/containers can now use "match ..." expressions for the slaying field.
        - properly close client-side dialogue when the player is teleported away.
        - map-tags did not properly close it's database tables or wait
          for a quiescent state, causing memory corruption on reload.
        - support "stat.xyz" accessor in match expressions.
        - skip /styles and /editor directories in cf::map::static_maps.
        - implement ->send_big_packet and use it in ext_msg (among other things, this
          fixes long answers from npc dialogue).
        - connected magic mouths no longer spill to Log-1, but use the examine tab.
        - (arch) change marker archetypes to not remove "marker" forces anymore
          and to not add a "put your code here" force needlessly.
        - (arch) fix or improve many plurals.
        - markers do no longer add a force if the slaying field is unset.
        - sped up search-items implementation, but it's still horrible.
        - (maps) bigchests are now properly non-unique, per_player and no_reset.
        - editor_folder can now be used to override whatever cfutil sets, and was
          used to reogianise the illogical arch tree a bit.

          corrupted if the length was >255.
        - support sub-matches in () inside match expressions, not just conditions.
        - got rid of motd/rules/news code in C++ part, move motd to it's own tab

        - implemented new "match" type that combines both check_inv and pedestal
          functionality (and more) inside the same object using the match expressions.
        - create simpler match expression compiles in many common cases.
        - reduce object size by removing obsolete "seen_by" member.
        - removed the rather broken make_list_like utility function, taking advantage
          of the new dynbuf::splice function (which gave an unexpected net win
          in code size...).
        - the server will no longer complain (and subtly fail) when an object
          being removed from a map causes another object to get removed.
        - banish strncpy from the server, speed up and simplify sending item
          descriptions to the client considerably.
        - add new "in head" set modifier for matches.
        - new BLOCKED_MOVE event added.
        - mapscript archetype now has activate_on_xxx true by default, as similar

        - display spell description for spellbooks, rods, wands, potion and scrolls,
          but not horns (to make them more useful for content-creators).
        - fix a number of bugs in check_move_on: 1) it didn't update the flags
          2) it skipped spell effects and 3) it didn't handle the case where
          and object was destroyed while iterating over it correctly. all this
          allowed players to sometimes walk onto spaces they should not be able to
          walk on.
        - fix an exploit where inscription/marking runes could execute arbitrary code.
        - examining an object now dumps the serialised object form when the user

        - identified skill-tools show what skill they grant.
        - display the duration of change_ability spells when examining them
          (missing: protection spells, but they are a hack...).
        - improve effectiveness of special foods created by woodsman skill,
          adding more variety to the different mushrooms.
        - fix a minor cfpod formatting bug.
        - do not talk about the hintmode so much - die-hards are expected to find
          the hintmode setting on the settings page.
        - IPO no longer lies about prices; prices tweaked.
        - clarified that all deliantra-specific parts are under the Affero GPL.
        - enable the object loader to also dump archetypes.
        - (maps) fix guild teleporters to Pupland Terminal.
        - (maps) put the trapdoor above the floor in sisters/necro_ruins1.
        - force the initial face when loading an object that is time-animated

        - fix a bug where recasting an ability changing spell could shorten
          its remaining duration.
        - fix pedestal and floor building with builder.
        - fix RUNATT attack mode, which was broken before (used e.g. by mice).

        - switch to YAML::XS from YAML.

2.80 Tue Sep 15 20:22:31 CEST 2009
        - fix the "screen stays black on login" bug and remove debug instrumentation
          that ultimately was not helpful to catch it :)
        - split outer_env into outer_env and outer_env_self, and fix
          all callers to use either one or the other, as appropriate. This
          fixes the (rather fragile) light spell, maybe others.
        - fixed an overflow and exploit in the bank/payment code.
        - fixed a bug in the jeweler quest and added the 'Tome of Jewelery'
          to explain the skill a bit more.

        - use better dependency tracking for include/keyword.h.
        - add accept-invitation and suicide to the list of asynchronous commands,

          for lots of code size savings.
        - monsters which breed new monsters shouldn't breed new monsters when
          they are sleeping: generators now check for the sleeping flag.

        - improve handling of los changes when inserting or removing
          objects, not perfect yet.
        - make map darkness signed (formerly unsigned) to allow
          ambient lighting and centrally manage darkness as an offset.

          tell users the current time and data, to improve awareness.
        - implement proper wizlook flag and handling of wizlook, instead
          of dumbly just clearing los once.

          when sending map changes.
        - remove most gcfclient and other client bug workarounds, as well
          as now obsolete protocol versions, simplying the code.

        - fix cfpod parsing when multiple verbatim blocks were separated by
          newlines.
        - increase monster detection radius from wis/5 to wis/3.

2.52  Thu Apr 24 11:47:19 CEST 2008
        - completely automate the item add/delete on remove/insert. this should fix
          all "ghost" item bugs caused by sloppy coding, as sloppy coding is now correct :)
        - completely automate the weight handling, should fix all weight
          accounting bugs caused by sloppy coding, as sloppy coding is now correct :)
        - reloading archetypes while a user was in the character creation phase
          could crash the server.

          to "is this really correct?", as many of those cases are now handles
          automatically by lower level code.
        - replace many ad-hoc checks for client visibility by object::visible_to,
          should result in broader applicability of functions using it.
        - merge items with different arch pointers refering to the same arch
          (due to archetype reloads).
        - refactored the object remove/insert functions and most related

          recommended configuration) (reported by Samuel Gondouin).
        - always put godgiven items into the player inventory, never any containers.
        - (maps, arch) the scorn go club was founded!
        - (arch) do no longer support player abilities, they didn't work anyways.
        - (arch) the alchemy spell is now of the alchemy spell school, which
          became a real spell-class.
        - (arch) the alchemist class now get an alchemy spell book for new characters.
        - (arch) considerably strengthened spark shower and destruction.
        - match archetypes by name, not by ptr, in treasure.C, this makes archetypes
          finally reloadable at runtime.
        - changed archetype loading algorithm to only require one pass and
          use delayed resolving of references.
        - examine command now uses the examine infobox.

        - write log messages in another thread, removing another sync point.
        - support multi-line log messages in a nicer way.

          this greatly increases timing accuracy and gets rid of an enourmous
          number of gettimeofday calls.
        - use a separate thread to signal aio completion, for lower latency.
        - require Coro 4.47, which fixes a data corruption bug with its C API.

2.42 Sat Mar 15 12:05:21 CET 2008

        - get rid of YAML::Syck, it's too buggy and misparses many files
          (this fixes the jeweler skill).
        - back-to-back perl_reloads don't freeze the ticker anymore.
        - convert cfutil from Event to EV (forgot to do this earlier...).
        - move tombstone to real map if player died due to cave-in (even if
          it has reset, which is better than putting it on the savebed, also as
          proof that the player didn't use a savebed).

2.4  Sun Jan 13 13:41:29 CET 2008
        - work around perl bug in configure perl module version check.
        - fix bug in golem move code that would cause a crash at tiling borders.

        - limited the number of items that can be picked up and dropped
          as temporary measurement against bad performance or dropping things
          (this lead to long freezes and triggered the watchdog).
        - improved the performance of the drop command a bit.
        - switch from Event to EV for higher performance, easier usage,
          less bugs...
        - updated to release version of the gnu affero license.

        - avoid backtraces due to old spells on some maps, sometimes causing
          crashes.

          potentially causing crashes.
        - assign weapons on user load time, not login-time, avoiding
          crashes.

2.3  Sat Oct 27 11:22:38 CEST 2007
        - fixed an important bug that caused passwords to be forgotten.
        - implement *tag destinations for goto, slaying etc. and use it
          in some of the maps.
        - bigworldised many maps (islands as in pupland and aldwulf),
          which is now trivial to do.
        - removed all traces of the old (and never working) plug-in interface
          (70kb code less on amd64).
        - improve/tune scheduling priorities.
        - fix some freezing bugs.

        - new sc (sound control) protocol command.
        - improve fxix protocol to include types.
        - exactly fill tcp segments, if possible.
        - output-rate is now an upper limit, the server will automatically
          (and quite perfectly) adjust to the network conditions, ensuring
          low latency even during bulk transfers (music, images, sounds etc.).
        - implement server-side widgets (i.e. client widgets controlled
          in the server side). this will allow future expansion without
          having to upgrade clients.
        - implement a (artwork) world map with realtime player position
          tracking.
        - new and more efficient extcmd (server still supports old extcmd
          protocol).
        - fixed lots of underflow/overflow bugs in diseases and general stats
          calcluation that could be easily exploited by users.
        - rebalanced diseases to spread more naturally/evenly.
        - completely asynchronous map loading even for tiled maps.
        - replace simple messaging protocol with channels carrying metadata
          (similar to message types, but more directed at the user).
        - reduce command processing latency by a whopping 120ms by
          reordering some processing steps inside the server. this directly
          reduces lag by 120ms.
        - actually send spell faces to the client.
        - implement player genders.
        - unclean logout/login results in: nothing if map hasn't reset,
          otherwise return to savebed and possible kill if the log-out
          was for too long.
        - fast socket-dead detection (kick player after 8 seconds without ack).
        - greatly reduce the cpu time needed to draw maps _again_.
        - archetypes are now subclasses of objects.
        - rebalanced shop greed and approval functions to be more realistic
          (and likely match the actual intention).
        - implement "crossfire pod" format for messages, with working bold,
          italic, gender-specific text, paragraphs etc.
        - implemented hint framework, players can opt to receive hints.
        - implemented (long) book framework, added some books from the cf wiki.
        - implement generic message framework that uses xml, utf8 for the client
          protocol and is capable of transmitting generic meta information.
        - implement (in a suboptimal way) per-player instantiated maps.
        - replace the nexus by a per-player tutorial map that teaches stuff
          better than the newbie house.
        - fix the magicmap colours.
        - optimise map update even more by removing unneeded code and checks.
        - decouple map and stats update from pl->ob and use pl->observe instead.
        - implement observe command.
        - major speed up in map refresh by replacing most get_map_from_coord
          calls with a simple comparison.
        - fix a latent crossfire bug that could crash the server because the
          map refresh did not update the mapspace.
        - support custom keys for regions and maps, regions are now
          refcount-managed.
        - allow worldmap overlays anywhere in the 000..999 range.
        - new system to acquire time slices for background jobs, to reduce
          jitter.
        - semi-persistent object-referencing framework (currently only players
          supported).
        - dependency tracking for perl extensions.
        - new slag-ex extension for cleaning cauldrons.
        - fix invoke result processing.
        - there are even less i/o syncpoints in the server now.
        - added map-tags extension that scans all maps for object tags
          and records them in the database (not used yet).
        - metaserver 2 support.
        - many more bugfixes and minor optimisations.

2.1  Sun May 27 04:21:29 CEST 2007
        - optimised event invocation (non-wanted events can now be
          skipped with 4-5 inlined instructions).
        - complete rewrite of town_portal: it now creates a portal
          to the "nearest" town only, travel is only possible
          to the town and back, anybody can use it (also removes
          one of the remaining syncpoints in the server).
        - complete rewrite of the range/attack skill slot system:
          there are now two slots, one for combat, one for ranged
          attacks.
        - introduce the concept of a current weapon (either a ranged
          or a combat weapon/skill/tool) and switch between them as
          needed.
        - rewrite bow code so bows get more useful: apply damage,
          attacktype and other stats to the arrows and treat
          bows as weapons. also rebalance the missile weapons skill
          so its damage increases with level.
        - rewrite the complete player speed logic: weapon_speed now
          works as documented and there are no unnatural speed boosts.
        - implement a utility - cfutil - that simplifies arch and map
          installation, replacing the old collect scripts and
          simplying deployment by scaling and cutting faces as required.
        - simplify the map protocol extensively by taking advantage
          of missing bigfaces, speeding up map generation immensely.
        - implement inherit keyword allowing archetypes to inherit from
          other archetypes.
        - rationalise archetype, region and treasurelist file format
          into a single file format and make them reloadable asynchronously.
        - make the worldmap, facedata (smoothing, faces, magicmap)
          reloadable at runtime.
        - implement 64x64 faceset support.
        - implement fxixsx protocol that saves
          a lot of bandwidth over the old image/face/smooth packets
          and allows images > packetsize, incremental and background
          transfers.
        - implement a bandwidth-saving smoothing protocol that works
          on a face basis as opposed to a mapspace basis.
        - the server can now rate-limit image uploads to not exceed
          a certain (client-configurable) speed while guarenteeing full
          freedom of movement.
        - implement new ex command to request item descriptions.
        - implement new msg command for in-game messages with meta
          information (using xml).
        - enforce utf-8 for all text messages.
        - added micropather (not used yet).
        - many, many bugfixes.

2.0  Tue Mar  6 15:22:53 CET 2007
        - make coroapi accessible to cf+.
        - moved map handling logic completely to perl
        - per player maps are now marked in the map
        - maps are saved completely differently now,
          and much more often.
        - rewrote map header parser and writer, to be much faster.
        - maps and players are now (in the average case) loaded
          and saved completely asynchronously, I/O contention will no
          longer freeze the server.
        - players and maps can be loaded anytime, without the player
          being logged in.
        - automatically generate method interfaces for perl from headers
        - unbundled freezethaw
        - mostly rewrote common/map.C
        - completely rewrite server/swap.C
        - introduced "runtime", the CCT clock (corrected crossfire time) :)
        - introduced new keyword for map files: file_format_version (integer, server version: 0)
        - better message for apply failures due to applymode
        - removed most all of the weather code
        - unified logging to stderr and file
        - too many minor changes to document
