 Revision history for libev, a high-performance and full-featured event loop.
 
-TODO: ev_walk
-TODO: remain
-TODO: EV_MINIMAL
+TODO: ABI??? API????? Changes???
+TODO: win32 write() to socket for signal handling
+TODO: poll asert
+TODO: EV_USE__XXX default with config, document
+	- "PORTING FROM LIBEV 3.X TO 4.X" (in ev.pod) is recommended reading.
+	- ev_embed_stop did not correctly stop the watcher (very good
+          testcase by Vladimir Timofeev).
+	- applied win32 fixes by Michael Lenaghan (also James Mansion).
+	- replace EV_MINIMAL by EV_FEATURES.
+        - prefer EPOLL_CTL_ADD over EPOLL_CTL_MOD in some more cases, as it
+          seems the former is *much* faster than the latter.
+        - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu).
+        - add (undocumented) EV_ENABLE when adding events with kqueue,
+          this might help with OS X, which seems to need it despite documenting
+          not to need it (helpfully pointed out by Tilghman Lesher).
+        - do not use poll by default on freebsd, it's broken (what isn't
+          on freebsd...).
+        - configure now prepends -O3, not appends it, so one can still
+          override it.
+        - disable poll backend on AIX, the poll header spams the namespace
+          and it's not worth working around dead platforms (reported
+          and analyzed by Aivars Kalvans).
+        - improve header file compatibility of the standalone eventfd code
+          in an obscure case.
+        - implement EV_AVOID_STDIO option.
+        - do not use sscanf to parse linux version number (smaller, faster,
+          no sscanf dependency).
+        - new EV_CHILD_ENABLE and EV_SIGNAL_ENABLE configurable settings.
+        - update libev.m4 HAVE_CLOCK_SYSCALL test for newer glibcs.
+        - add section on accept() problems to the manpage.
+        - rename EV_TIMEOUT to EV_TIMER.
+        - rename ev_loop_count/depth/verify.
+        - switch to two-digit minor version.
 
-        - new functionality: ev_set_userdata, ev_userdata,
-          ev_set_invoke_pending_cb, ev_set_loop_release_cb,
-          ev_invoke_pending, together with a long example about thread
-          locking.

+	- signalfd is no longer used by default and has to be requested
+          explicitly - this means that easy to catch bugs become hard to
+          catch race conditions, but the users have spoken.
+        - point out the unspecified signal mask in the documentation, and
+          that this is a race condition regardless of EV_SIGNALFD.
+	- backport inotify code to C89.
+        - inotify file descriptors could leak into child processes.
+        - ev_stat watchers could keep an errornous extra ref on the loop,
+          preventing exit when unregistering all watchers (testcases
+          provided by ry@tinyclouds.org).
+        - implement EV_WIN32_HANDLE_TO_FD and EV_WIN32_CLOSE_FD configuration
+          symbols to make it easier for apps to do their own fd management.
+        - support EV_IDLE_ENABLE being disabled in ev++.h
+          (patch by Didier Spezia).
+        - take advantage of inotify_init1, if available, to set cloexec/nonblock
+          on fd creation, to avoid races.
+        - the signal handling pipe wasn't always initialised under windows
+          (analysed by lekma).
+        - changed minimum glibc requirement from glibc 2.9 to 2.7, for
+          signalfd.
+        - add missing string.h include (Denis F. Latypoff).
+        - only replace ev_stat.prev when we detect an actual difference,
+          so prev is (almost) always different to attr. this might
+          have caused the probems with 04_stat.t.
+        - add ev::timer->remaining () method to C++ API.
+
+3.8  Sun Aug  9 14:30:45 CEST 2009
+	- incompatible change: do not necessarily reset signal handler
+          to SIG_DFL when a sighandler is stopped.
+        - ev_default_destroy did not properly free or zero some members,
+          potentially causing crashes and memory corruption on repated
+          ev_default_destroy/ev_default_loop calls.
+	- take advantage of signalfd on GNU/Linux systems.
+	- document that the signal mask might be in an unspecified
+          state when using libev's signal handling.
+        - take advantage of some GNU/Linux calls to set cloexec/nonblock
+          on fd creation, to avoid race conditions.

+3.7  Fri Jul 17 16:36:32 CEST 2009
 	- ev_unloop and ev_loop wrongly used a global variable to exit loops,
           instead of using a per-loop variable (bug caught by accident...).
+	- the ev_set_io_collect_interval interpretation has changed.
+        - add new functionality: ev_set_userdata, ev_userdata,
+          ev_set_invoke_pending_cb, ev_set_loop_release_cb,
+          ev_invoke_pending, ev_pending_count, together with a long example
+          about thread locking.
+        - add ev_timer_remaining (as requested by Denis F. Latypoff).
+        - add ev_loop_depth.
         - calling ev_unloop in fork/prepare watchers will no longer poll
           for new events.
 	- Denis F. Latypoff corrected many typos in example code snippets.
-	- the ev_set_io_collect_interval interpretation has changed.
         - honor autoconf detection of EV_USE_CLOCK_SYSCALL, also double-
           check that the syscall number is available before trying to
           use it (reported by ry@tinyclouds).
