3TODO: ev_time_freeze, ev_time_thaw 3 - applied win32 fixes by Michael Lenaghan.
4TODO: ev_walk 4 - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu).
5TODO: ev_stop_all 5 - configure now prepends -O3, not appends it, so one can still
6TODO: fix signal handling(?) under win32 6 override it.

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

36 - incompatible change: do not necessarily reset signal handler
37 to SIG_DFL when a sighandler is stopped.
38 - ev_default_destroy did not properly free or zero some members,
39 potentially causing crashes and memory corruption on repated
40 ev_default_destroy/ev_default_loop calls.
41 - take advantage of signalfd on GNU/Linux systems.
42 - document that the signal mask might be in an unspecified
43 state when using libev's signal handling.
44 - take advantage of some GNU/Linux calls to set cloexec/nonblock
45 on fd creation, to avoid race conditions.

473.7 Fri Jul 17 16:36:32 CEST 2009
48 - ev_unloop and ev_loop wrongly used a global variable to exit loops,
49 instead of using a per-loop variable (bug caught by accident...).
50 - the ev_set_io_collect_interval interpretation has changed.
51 - add new functionality: ev_set_userdata, ev_userdata,
52 ev_set_invoke_pending_cb, ev_set_loop_release_cb,
53 ev_invoke_pending, ev_pending_count, together with a long example
54 about thread locking.
55 - add ev_timer_remaining (as requested by Denis F. Latypoff).
56 - add ev_loop_depth.
57 - calling ev_unloop in fork/prepare watchers will no longer poll
58 for new events.
59 - Denis F. Latypoff corrected many typos in example code snippets.
60 - honor autoconf detection of EV_USE_CLOCK_SYSCALL, also double-
61 check that the syscall number is available before trying to
62 use it (reported by ry@tinyclouds).
63 - use GetSystemTimeAsFileTime instead of _timeb on windows, for
64 slightly higher accuracy.
65 - properly declare ev_loop_verify and ev_now_update even when
66 !EV_MULTIPLICITY.
67 - do not compile in any priority code when EV_MAXPRI == EV_MINPRI.
68 - support EV_MINIMAL==2 for a reduced API.
69 - actually 0-initialise struct sigaction when installing signals.
70 - add section on hibernate and stopped processes to ev_timer docs.

73 - multiple timers becoming ready within an event loop iteration
74 will be invoked in the "correct" order now.
8 - do not leave the event loop early just because we have no active 75 - do not leave the event loop early just because we have no active
9 watchers, fixing a problem when embedding a kqueue loop 76 watchers, fixing a problem when embedding a kqueue loop
10 that has active kernel events but no registered watchers 77 that has active kernel events but no registered watchers
11 (reported by blacksand blacksand). 78 (reported by blacksand blacksand).
12 - correctly zero the idx values for arrays, so destroying and 79 - correctly zero the idx values for arrays, so destroying and
13 reinitialising the default loop actually works (patch by 80 reinitialising the default loop actually works (patch by
14 Malek Hadj-Ali). 81 Malek Hadj-Ali).
82 - implement ev_suspend and ev_resume.
15 - new EV_CUSTOM revents flag for use by applications. 83 - new EV_CUSTOM revents flag for use by applications.
84 - add documentation section about priorites.
85 - add a glossary to the dcoumentation.
86 - extend the ev_fork description slightly.
87 - optimize a jump out of call_pending.

19 failed assertion on event loop creation (patch by Malek Hadj-Ali). 91 failed assertion on event loop creation (patch by Malek Hadj-Ali).
