16 - destroying a non-default loop would stop the global waitpid
17 watcher (Denis Bilenko).
18 - queueing pending watchers of higher priority from a watcher now invokes
19 them in a timely fashion (reported by Denis Bilenko).
20 - add throw() to all libev functions that cannot throw exceptions, for
21 further code size decrease when compiling for C++.
22 - add throw () to callbacks that must not throw exceptions (allocator,
23 syserr, loop acquire/release, periodic reschedule cbs).
24 - fix event_base_loop return code, add event_get_callback, event_base_new,
25 event_base_get_method calls to improve libevent 1.x emulation and add
26 some libevent 2.x functionality (based on a patch by Jeff Davey).
27 - add more memory fences to fix a bug reported by Jeff Davey. Better
28 be overfenced than underprotected.
29 - ev_run now returns a boolean status (true meaning watchers are
30 still active).
31 - ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with
32 libev's EV_ERROR (reported by 191919).
33 - (ecb) add memory fence support for xlC (Darin McBride).
34 - (ecb) add memory fence support for gcc-mips (Anton Kirilov).
35 - (ecb) add memory fence support for gcc-alpha (Christian Weisgerber).
36 - work around some kernels losing file descriptors by leaking
37 the kqueue descriptor in the child.
38 - work around linux inotify not reporting IN_ATTRIB changes for directories
39 in many cases.
40 - include sys/syscall.h instead of plain syscall.h.
41 - check for io watcher loops in ev_verify, check for the most
42 common reported usage bug in ev_io_start.
43 - chose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET.
44 - always use WSASend/WSARecv directly on windows, hoping that this
45 works in all cases (unlike read/write/send/recv...).
46 - try to detect signals around a fork faster (test program by
47 Denis Bilenko).
48 - work around recent glibc versions that leak memory in realloc.
49 - rename ev::embed::set to ev::embed::set_embed to avoid clashing
50 the watcher base set (loop) method.
51 - rewrite the async/signal pipe logic to always keep a valid fd, which
52 simplifies (and hopefuly correctifies :) the race checking
53 on fork, at the cost of one extra fd.
54 - add fat, msdos, jffs2, ramfs, ntfs and btrfs to the list of
55 inotify-supporting filesystems.
