3TODO: include ev_xyz_start in each example?
4 - "PORTING FROM LIBEV 3.X TO 4.X" (in ev.pod) is recommended reading.
5 - ev_embed_stop did not correctly stop the watcher (very good
6 testcase by Vladimir Timofeev).
7 - ev_run will now always update the current loop time - it erroneously
8 didn't when idle watchers were active, causing timers not to fire.
9 - fix a bug where a timeout of zero caused the timer not to fire
10 in the libevent emulation (testcase by Péter Szabó).
11 - applied win32 fixes by Michael Lenaghan (also James Mansion).
12 - replace EV_MINIMAL by EV_FEATURES.
13 - prefer EPOLL_CTL_ADD over EPOLL_CTL_MOD in some more cases, as it
14 seems the former is *much* faster than the latter.
15 - reduce the number of spurious wake-ups with the ports backend.
16 - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu).
17 - do async init within ev_async_start, not ev_async_set, which avoids
18 an API quirk where the set function must be called in the C++ API
19 even when there is nothing to set.
20 - add (undocumented) EV_ENABLE when adding events with kqueue,
21 this might help with OS X, which seems to need it despite documenting
22 not to need it (helpfully pointed out by Tilghman Lesher).
23 - do not use poll by default on freebsd, it's broken (what isn't
24 on freebsd...).
25 - configure now prepends -O3, not appends it, so one can still
26 override it.
27 - ev.pod: greatly expanded the portability section, added a porting
28 section, a description of watcher states and made lots of minor fixes.
29 - disable poll backend on AIX, the poll header spams the namespace
30 and it's not worth working around dead platforms (reported
31 and analyzed by Aivars Kalvans).
32 - improve header file compatibility of the standalone eventfd code
33 in an obscure case.
34 - implement EV_AVOID_STDIO option.
35 - do not use sscanf to parse linux version number (smaller, faster,
36 no sscanf dependency).
37 - new EV_CHILD_ENABLE and EV_SIGNAL_ENABLE configurable settings.
38 - update libev.m4 HAVE_CLOCK_SYSCALL test for newer glibcs.
39 - add section on accept() problems to the manpage.
40 - rename EV_TIMEOUT to EV_TIMER.
41 - rename ev_loop_count/depth/verify/loop/unloop.
42 - switch to two-digit minor version.
43 - work around an apparent gentoo compiler bug.
44 - define _DARWIN_UNLIMITED_SELECT. just so.
45 - use enum instead of #define for most constants.
46 - improve compatibility to older C++ compilers.
47 - ev_run/ev_default_loop/ev_break/ev_loop_new have now default
48 arguments when compiled as C++.
