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

23 - signalfd is no longer used by default and has to be requested
24 explicitly - this means that easy to catch bugs become hard to
25 catch race conditions, but the users have spoken.
26 - point out the unspecified signal mask in the documentation, and
27 that this is a race condition regardless of EV_SIGNALFD.
28 - backport inotify code to C89.
29 - inotify file descriptors could leak into child processes.
30 - ev_stat watchers could keep an errornous extra ref on the loop,
31 preventing exit when unregistering all watchers (testcases
32 provided by ry@tinyclouds.org).
33 - implement EV_WIN32_HANDLE_TO_FD and EV_WIN32_CLOSE_FD configuration
34 symbols to make it easier for apps to do their own fd management.
35 - support EV_IDLE_ENABLE being disabled in ev++.h
36 (patch by Didier Spezia).
37 - take advantage of inotify_init1, if available, to set cloexec/nonblock
38 on fd creation, to avoid races.
39 - the signal handling pipe wasn't always initialised under windows
40 (analysed by lekma).
41 - changed minimum glibc requirement from glibc 2.9 to 2.7, for
42 signalfd.
43 - add missing string.h include (Denis F. Latypoff).
44 - only replace ev_stat.prev when we detect an actual difference,
45 so prev is (almost) always different to attr. this might
46 have caused the probems with 04_stat.t.
47 - add ev::timer->remaining () method to C++ API.

493.8 Sun Aug 9 14:30:45 CEST 2009
50 - incompatible change: do not necessarily reset signal handler
51 to SIG_DFL when a sighandler is stopped.
52 - ev_default_destroy did not properly free or zero some members,
53 potentially causing crashes and memory corruption on repated
54 ev_default_destroy/ev_default_loop calls.
55 - take advantage of signalfd on GNU/Linux systems.
56 - document that the signal mask might be in an unspecified
57 state when using libev's signal handling.
58 - take advantage of some GNU/Linux calls to set cloexec/nonblock
59 on fd creation, to avoid race conditions.

613.7 Fri Jul 17 16:36:32 CEST 2009
62 - ev_unloop and ev_loop wrongly used a global variable to exit loops,
63 instead of using a per-loop variable (bug caught by accident...).
64 - the ev_set_io_collect_interval interpretation has changed.
65 - add new functionality: ev_set_userdata, ev_userdata,
66 ev_set_invoke_pending_cb, ev_set_loop_release_cb,
67 ev_invoke_pending, ev_pending_count, together with a long example
68 about thread locking.
69 - add ev_timer_remaining (as requested by Denis F. Latypoff).
70 - add ev_loop_depth.
71 - calling ev_unloop in fork/prepare watchers will no longer poll
72 for new events.
73 - Denis F. Latypoff corrected many typos in example code snippets.
74 - honor autoconf detection of EV_USE_CLOCK_SYSCALL, also double-
75 check that the syscall number is available before trying to
76 use it (reported by ry@tinyclouds).
77 - use GetSystemTimeAsFileTime instead of _timeb on windows, for
78 slightly higher accuracy.
79 - properly declare ev_loop_verify and ev_now_update even when
80 !EV_MULTIPLICITY.
81 - do not compile in any priority code when EV_MAXPRI == EV_MINPRI.
82 - support EV_MINIMAL==2 for a reduced API.
83 - actually 0-initialise struct sigaction when installing signals.
84 - add section on hibernate and stopped processes to ev_timer docs.
85
863.6 Tue Apr 28 02:49:30 CEST 2009
87 - multiple timers becoming ready within an event loop iteration
88 will be invoked in the "correct" order now.
89 - do not leave the event loop early just because we have no active
90 watchers, fixing a problem when embedding a kqueue loop
91 that has active kernel events but no registered watchers
92 (reported by blacksand blacksand).
93 - correctly zero the idx values for arrays, so destroying and
94 reinitialising the default loop actually works (patch by
95 Malek Hadj-Ali).
96 - implement ev_suspend and ev_resume.
97 - new EV_CUSTOM revents flag for use by applications.
98 - add documentation section about priorites.
99 - add a glossary to the dcoumentation.
100 - extend the ev_fork description slightly.
101 - optimize a jump out of call_pending.
102
1033.53 Sun Feb 15 02:38:20 CET 2009
104 - fix a bug in event pipe creation on win32 that would cause a
105 failed assertion on event loop creation (patch by Malek Hadj-Ali).
106 - probe for CLOCK_REALTIME support at runtime as well and fall
107 back to gettimeofday if there is an error, to support older
108 operating systems with newer header files/libraries.
109 - prefer gettimeofday over clock_gettime with USE_CLOCK_SYSCALL
110 (default most everywhere), otherwise not.

113 - fix compilation of select backend in fd_set mode when NFDBITS is
114 missing (to get it to compile on QNX, reported by Rodrigo Campos).
115 - better select-nfds handling when select backend is in fd_set mode.
116 - diagnose fd_set overruns when select backend is in fd_set mode.
117 - due to a thinko, instead of disabling everything but
118 select on the borked OS X platform, everything but select was
119 allowed (reported by Emanuele Giaquinta).

7 should return fantasy port numbers. 124 should return fantasy port numbers.
125 - include "libev" in all assertion messages for potentially
126 clearer diagnostics.
127 - event_get_version (libevent compatibility) returned
128 a useless string instead of the expected version string
129 (patch by W.C.A. Wijngaards).
