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

29 - signalfd is no longer used by default and has to be requested
30 explicitly - this means that easy to catch bugs become hard to
31 catch race conditions, but the users have spoken.
32 - point out the unspecified signal mask in the documentation, and
33 that this is a race condition regardless of EV_SIGNALFD.
34 - backport inotify code to C89.
35 - inotify file descriptors could leak into child processes.
36 - ev_stat watchers could keep an errornous extra ref on the loop,
37 preventing exit when unregistering all watchers (testcases
38 provided by ry@tinyclouds.org).
39 - implement EV_WIN32_HANDLE_TO_FD and EV_WIN32_CLOSE_FD configuration
40 symbols to make it easier for apps to do their own fd management.
41 - support EV_IDLE_ENABLE being disabled in ev++.h
42 (patch by Didier Spezia).
43 - take advantage of inotify_init1, if available, to set cloexec/nonblock
44 on fd creation, to avoid races.
45 - the signal handling pipe wasn't always initialised under windows
46 (analysed by lekma).
47 - changed minimum glibc requirement from glibc 2.9 to 2.7, for
48 signalfd.
49 - add missing string.h include (Denis F. Latypoff).
50 - only replace ev_stat.prev when we detect an actual difference,
51 so prev is (almost) always different to attr. this might
52 have caused the probems with 04_stat.t.
53 - add ev::timer->remaining () method to C++ API.
54
553.8 Sun Aug 9 14:30:45 CEST 2009
56 - incompatible change: do not necessarily reset signal handler
57 to SIG_DFL when a sighandler is stopped.
58 - ev_default_destroy did not properly free or zero some members,
59 potentially causing crashes and memory corruption on repated
60 ev_default_destroy/ev_default_loop calls.
61 - take advantage of signalfd on GNU/Linux systems.
62 - document that the signal mask might be in an unspecified
63 state when using libev's signal handling.
64 - take advantage of some GNU/Linux calls to set cloexec/nonblock
65 on fd creation, to avoid race conditions.
66
673.7 Fri Jul 17 16:36:32 CEST 2009
68 - ev_unloop and ev_loop wrongly used a global variable to exit loops,
69 instead of using a per-loop variable (bug caught by accident...).
70 - the ev_set_io_collect_interval interpretation has changed.
71 - add new functionality: ev_set_userdata, ev_userdata,
72 ev_set_invoke_pending_cb, ev_set_loop_release_cb,
73 ev_invoke_pending, ev_pending_count, together with a long example
74 about thread locking.
75 - add ev_timer_remaining (as requested by Denis F. Latypoff).
76 - add ev_loop_depth.
77 - calling ev_unloop in fork/prepare watchers will no longer poll
78 for new events.
79 - Denis F. Latypoff corrected many typos in example code snippets.
80 - honor autoconf detection of EV_USE_CLOCK_SYSCALL, also double-
81 check that the syscall number is available before trying to
82 use it (reported by ry@tinyclouds).
83 - use GetSystemTimeAsFileTime instead of _timeb on windows, for
84 slightly higher accuracy.
85 - properly declare ev_loop_verify and ev_now_update even when
86 !EV_MULTIPLICITY.
87 - do not compile in any priority code when EV_MAXPRI == EV_MINPRI.
88 - support EV_MINIMAL==2 for a reduced API.
89 - actually 0-initialise struct sigaction when installing signals.
90 - add section on hibernate and stopped processes to ev_timer docs.
91
923.6 Tue Apr 28 02:49:30 CEST 2009
93 - multiple timers becoming ready within an event loop iteration
94 will be invoked in the "correct" order now.
95 - do not leave the event loop early just because we have no active
96 watchers, fixing a problem when embedding a kqueue loop
97 that has active kernel events but no registered watchers
98 (reported by blacksand blacksand).
99 - correctly zero the idx values for arrays, so destroying and
100 reinitialising the default loop actually works (patch by
101 Malek Hadj-Ali).
102 - implement ev_suspend and ev_resume.
103 - new EV_CUSTOM revents flag for use by applications.
104 - add documentation section about priorites.
105 - add a glossary to the dcoumentation.
106 - extend the ev_fork description slightly.
107 - optimize a jump out of call_pending.
108
1093.53 Sun Feb 15 02:38:20 CET 2009
110 - fix a bug in event pipe creation on win32 that would cause a
111 failed assertion on event loop creation (patch by Malek Hadj-Ali).
112 - probe for CLOCK_REALTIME support at runtime as well and fall
113 back to gettimeofday if there is an error, to support older
114 operating systems with newer header files/libraries.
115 - prefer gettimeofday over clock_gettime with USE_CLOCK_SYSCALL
116 (default most everywhere), otherwise not.
