3TODO: ABI??? API????? Changes???
4TODO: win32 write() to socket for signal handling
5 - ev_embed_stop did not correctly stop the watcher (very good
6 testcase by Vladimir Timofeev).
7 - applied win32 fixes by Michael Lenaghan (also James Mansion).
8 - replace EV_MINIMAL by EV_FEATURES.
9 - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu).
10 - configure now prepends -O3, not appends it, so one can still
11 override it.
12 - disable poll backend on AIX, the poll header spams the namespace
13 and it's not worth working around dead platforms (reported
14 and analyzed by Aivars Kalvans).
15 - improve header file compatibility of the standalone eventfd code
16 in an obscure case.
17 - implement EV_AVOID_STDIO option.
18 - do not use sscanf to parse linux version number (smaller, faster,
19 no sscanf dependency).
20 - new EV_CHILD_ENABLE and EV_SIGNAL_ENABLE configurable settings.
21 - update libev.m4 HAVE_CLOCK_SYSCALL test for newwer glibcs.
22 - add section on accept() problems to the manpage.
23 - rename EV_TIMEOUT to EV_TIMER.
24 - remove loop_ name component from ev_loop_count/depth/verify.
25 - switch to two-digit minor version.

28 - signalfd is no longer used by default and has to be requested
29 explicitly - this means that easy to catch bugs become hard to
30 catch race conditions, but the users have spoken.
31 - point out the unspecified signal mask in the documentation, and
32 that this is a race condition regardless of EV_SIGNALFD.
33 - backport inotify code to C89.
34 - inotify file descriptors could leak into child processes.
35 - ev_stat watchers could keep an errornous extra ref on the loop,
36 preventing exit when unregistering all watchers (testcases
37 provided by ry@tinyclouds.org).
38 - implement EV_WIN32_HANDLE_TO_FD and EV_WIN32_CLOSE_FD configuration
39 symbols to make it easier for apps to do their own fd management.
40 - support EV_IDLE_ENABLE being disabled in ev++.h
41 (patch by Didier Spezia).
42 - take advantage of inotify_init1, if available, to set cloexec/nonblock
43 on fd creation, to avoid races.
44 - the signal handling pipe wasn't always initialised under windows
45 (analysed by lekma).
46 - changed minimum glibc requirement from glibc 2.9 to 2.7, for
47 signalfd.
48 - add missing string.h include (Denis F. Latypoff).
49 - only replace ev_stat.prev when we detect an actual difference,
50 so prev is (almost) always different to attr. this might
51 have caused the probems with 04_stat.t.
52 - add ev::timer->remaining () method to C++ API.
53
543.8 Sun Aug 9 14:30:45 CEST 2009
55 - incompatible change: do not necessarily reset signal handler
56 to SIG_DFL when a sighandler is stopped.
57 - ev_default_destroy did not properly free or zero some members,
58 potentially causing crashes and memory corruption on repated
59 ev_default_destroy/ev_default_loop calls.
60 - take advantage of signalfd on GNU/Linux systems.
61 - document that the signal mask might be in an unspecified
62 state when using libev's signal handling.
63 - take advantage of some GNU/Linux calls to set cloexec/nonblock
64 on fd creation, to avoid race conditions.
65
663.7 Fri Jul 17 16:36:32 CEST 2009
67 - ev_unloop and ev_loop wrongly used a global variable to exit loops,
68 instead of using a per-loop variable (bug caught by accident...).
69 - the ev_set_io_collect_interval interpretation has changed.
70 - add new functionality: ev_set_userdata, ev_userdata,
71 ev_set_invoke_pending_cb, ev_set_loop_release_cb,
72 ev_invoke_pending, ev_pending_count, together with a long example
73 about thread locking.
74 - add ev_timer_remaining (as requested by Denis F. Latypoff).
75 - add ev_loop_depth.
76 - calling ev_unloop in fork/prepare watchers will no longer poll
77 for new events.
78 - Denis F. Latypoff corrected many typos in example code snippets.
79 - honor autoconf detection of EV_USE_CLOCK_SYSCALL, also double-
80 check that the syscall number is available before trying to
81 use it (reported by ry@tinyclouds).
82 - use GetSystemTimeAsFileTime instead of _timeb on windows, for
83 slightly higher accuracy.
84 - properly declare ev_loop_verify and ev_now_update even when
85 !EV_MULTIPLICITY.
86 - do not compile in any priority code when EV_MAXPRI == EV_MINPRI.
87 - support EV_MINIMAL==2 for a reduced API.
88 - actually 0-initialise struct sigaction when installing signals.
89 - add section on hibernate and stopped processes to ev_timer docs.

913.6 Tue Apr 28 02:49:30 CEST 2009
92 - multiple timers becoming ready within an event loop iteration
93 will be invoked in the "correct" order now.
94 - do not leave the event loop early just because we have no active
95 watchers, fixing a problem when embedding a kqueue loop
96 that has active kernel events but no registered watchers
97 (reported by blacksand blacksand).
98 - correctly zero the idx values for arrays, so destroying and
99 reinitialising the default loop actually works (patch by
100 Malek Hadj-Ali).
101 - implement ev_suspend and ev_resume.
102 - new EV_CUSTOM revents flag for use by applications.
103 - add documentation section about priorites.
104 - add a glossary to the dcoumentation.
105 - extend the ev_fork description slightly.
106 - optimize a jump out of call_pending.
107
1083.53 Sun Feb 15 02:38:20 CET 2009
109 - fix a bug in event pipe creation on win32 that would cause a
110 failed assertion on event loop creation (patch by Malek Hadj-Ali).
111 - probe for CLOCK_REALTIME support at runtime as well and fall
112 back to gettimeofday if there is an error, to support older
113 operating systems with newer header files/libraries.
114 - prefer gettimeofday over clock_gettime with USE_CLOCK_SYSCALL
115 (default most everywhere), otherwise not.
