7 - change the default periodic reschedule function to hopefully be more
8 exact and correct even in corner cases or in the far future.
9 - document reasonable ranges for interval and offset.
10 - do not rely on -lm anymore: use it when available but use our
11 own floor () if it is missing. This should make it easier to embed.

134.04 Wed Feb 16 09:01:51 CET 2011
14 - fix two problems in the native win32 backend, where reuse of fd's
15 with different underlying handles caused handles not to be removed
16 or added to the select set (analyzed and tested by Bert Belder).
17 - do no rely on ceil() in ev_e?poll.c.
18 - backport libev to HP-UX versions before 11 v3.
19 - configure did not detect nanosleep and clock_gettime properly when
20 they are available in the libc (as opposed to -lrt).
21
224.03 Tue Jan 11 14:37:25 CET 2011
23 - officially support polling files with all backends.
24 - support files, /dev/zero etc. the same way as select in the epoll
25 backend, by generating events on our own.
26 - ports backend: work around solaris bug 6874410 and many related ones
27 (EINTR, maybe more), with no performance loss (note that the solaris
28 bug report is actually wrong, reality is far more bizarre and broken
29 than that).
30 - define EV_READ/EV_WRITE as macros in event.h, as some programs use
31 #ifdef to test for them.
32 - new (experimental) function: ev_feed_signal.
33 - new (to become default) EVFLAG_NOSIGMASK flag.
34 - new EVBACKEND_MASK symbol.
35 - updated COMMON IDIOMS SECTION.
36
374.01 Fri Nov 5 21:51:29 CET 2010
38 - automake fucked it up, apparently, --add-missing -f is not quite enough
39 to make it update its files, so 4.00 didn't install ev++.h and
40 event.h on make install. grrr.
41 - ev_loop(count|depth) didn't return anything (Robin Haberkorn).
42 - change EV_UNDEF to 0xffffffff to silence some overzealous compilers.
43 - use "(libev) " prefix for all libev error messages now.

5 - "PORTING FROM LIBEV 3.X TO 4.X" (in ev.pod) is recommended reading. 46 - "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 47 - ev_embed_stop did not correctly stop the watcher (very good
7 testcase by Vladimir Timofeev). 48 testcase by Vladimir Timofeev).
49 - ev_run will now always update the current loop time - it erroneously
50 didn't when idle watchers were active, causing timers not to fire.
51 - fix a bug where a timeout of zero caused the timer not to fire
52 in the libevent emulation (testcase by Péter Szabó).
8 - applied win32 fixes by Michael Lenaghan (also James Mansion). 53 - applied win32 fixes by Michael Lenaghan (also James Mansion).
9 - replace EV_MINIMAL by EV_FEATURES. 54 - replace EV_MINIMAL by EV_FEATURES.
55 - prefer EPOLL_CTL_ADD over EPOLL_CTL_MOD in some more cases, as it
56 seems the former is *much* faster than the latter.
57 - linux kernel version detection (for inotify bug workarounds)
58 did not work properly.
59 - reduce the number of spurious wake-ups with the ports backend.
10 - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu). 60 - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu).
61 - do async init within ev_async_start, not ev_async_set, which avoids
62 an API quirk where the set function must be called in the C++ API
63 even when there is nothing to set.
11 - add (undocumented) EV_ENABLE when adding events with kqueue, 64 - add (undocumented) EV_ENABLE when adding events with kqueue,
65 this might help with OS X, which seems to need it despite documenting
12 this might help (helpfully pointed out by Tilghman Lesher). 66 not to need it (helpfully pointed out by Tilghman Lesher).
67 - do not use poll by default on freebsd, it's broken (what isn't
68 on freebsd...).
69 - allow to embed epoll on kernels >= 2.6.32.
13 - configure now prepends -O3, not appends it, so one can still 70 - configure now prepends -O3, not appends it, so one can still
14 override it. 71 override it.
72 - ev.pod: greatly expanded the portability section, added a porting
73 section, a description of watcher states and made lots of minor fixes.
15 - disable poll backend on AIX, the poll header spams the namespace 74 - disable poll backend on AIX, the poll header spams the namespace
16 and it's not worth working around dead platforms (reported 75 and it's not worth working around dead platforms (reported
