7 - define EV_READ/EV_WRITE as macros in event.h, as some programs use
8 #ifdef to test for them.

11 - automake fucked it up, apparently, --add-missing -f is not quite enough
12 to make it update its files, so 4.00 didn't install ev++.h and
13 event.h on make install. grrr.
14 - ev_loop(count|depth) didn't return anything (Robin Haberkorn).
15 - change EV_UNDEF to 0xffffffff to silence some overzealous compilers.
16 - use "(libev) " prefix for all libev error messages now.

5 - "PORTING FROM LIBEV 3.X TO 4.X" (in ev.pod) is recommended reading. 19 - "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 20 - ev_embed_stop did not correctly stop the watcher (very good
7 testcase by Vladimir Timofeev). 21 testcase by Vladimir Timofeev).
22 - ev_run will now always update the current loop time - it erroneously
23 didn't when idle watchers were active, causing timers not to fire.
24 - fix a bug where a timeout of zero caused the timer not to fire
25 in the libevent emulation (testcase by Péter Szabó).
8 - applied win32 fixes by Michael Lenaghan (also James Mansion). 26 - applied win32 fixes by Michael Lenaghan (also James Mansion).
9 - replace EV_MINIMAL by EV_FEATURES. 27 - replace EV_MINIMAL by EV_FEATURES.
28 - prefer EPOLL_CTL_ADD over EPOLL_CTL_MOD in some more cases, as it
29 seems the former is *much* faster than the latter.
30 - linux kernel version detection (for inotify bug workarounds)
31 did not work properly.
32 - reduce the number of spurious wake-ups with the ports backend.
10 - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu). 33 - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu).
34 - do async init within ev_async_start, not ev_async_set, which avoids
35 an API quirk where the set function must be called in the C++ API
36 even when there is nothing to set.
11 - add (undocumented) EV_ENABLE when adding events with kqueue, 37 - add (undocumented) EV_ENABLE when adding events with kqueue,
38 this might help with OS X, which seems to need it despite documenting
12 this might help (helpfully pointed out by Tilghman Lesher). 39 not to need it (helpfully pointed out by Tilghman Lesher).
40 - do not use poll by default on freebsd, it's broken (what isn't
41 on freebsd...).
42 - allow to embed epoll on kernels >= 2.6.32.
13 - configure now prepends -O3, not appends it, so one can still 43 - configure now prepends -O3, not appends it, so one can still
14 override it. 44 override it.
45 - ev.pod: greatly expanded the portability section, added a porting
46 section, a description of watcher states and made lots of minor fixes.
15 - disable poll backend on AIX, the poll header spams the namespace 47 - disable poll backend on AIX, the poll header spams the namespace
16 and it's not worth working around dead platforms (reported 48 and it's not worth working around dead platforms (reported

28 - switch to two-digit minor version. 61 - switch to two-digit minor version.
62 - work around an apparent gentoo compiler bug.
63 - define _DARWIN_UNLIMITED_SELECT. just so.
64 - use enum instead of #define for most constants.
65 - improve compatibility to older C++ compilers.
66 - (experimental) ev_run/ev_default_loop/ev_break/ev_loop_new have now
67 default arguments when compiled as C++.
68 - enable automake dependency tracking.
69 - ev_loop_new no longer leaks memory when loop creation failed.
