18 - when not using autoconf, tighten the check for clock_gettime and related
19 functionality.

22 - events on files were not always generated properly with the
23 epoll backend (testcase by Assaf Inbal).
24 - mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
25 - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
26 - use a reasonable fallback for EV_NSIG instead of erroring out
27 when we can't detect the signal set size.
28 - in the absence of autoconf, do not use the clock syscall
29 on glibc >= 2.17 (avoids the syscall AND -lrt on systems
30 doing clock_gettime in userspace).
31 - ensure extern "C" function pointers are used for externally-visible
32 loop callbacks (not watcher callbacks yet).
33 - (ecb) work around memory barriers and volatile apparently both being
34 broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).

37 - destroying a non-default loop would stop the global waitpid
38 watcher (Denis Bilenko).
8 - queueing pending watchers of higher priority from a watcher now invokes 39 - queueing pending watchers of higher priority from a watcher now invokes
9 them in a timely fashion (reported by Denis Bilenko). 40 them in a timely fashion (reported by Denis Bilenko).

11 further code size decrease when compiling for C++. 42 further code size decrease when compiling for C++.
12 - add throw () to callbacks that must not throw exceptions (allocator, 43 - add throw () to callbacks that must not throw exceptions (allocator,
13 syserr, loop acquire/release, periodic reschedule cbs). 44 syserr, loop acquire/release, periodic reschedule cbs).
14 - fix event_base_loop return code, add event_get_callback, event_base_new, 45 - fix event_base_loop return code, add event_get_callback, event_base_new,
15 event_base_get_method calls to improve libevent 1.x emulation and add 46 event_base_get_method calls to improve libevent 1.x emulation and add
16 some libevent 2.x funcitonality (based on a patch by Jeff Davey). 47 some libevent 2.x functionality (based on a patch by Jeff Davey).

27 the kqueue descriptor in the child. 58 the kqueue descriptor in the child.
59 - work around linux inotify not reporting IN_ATTRIB changes for directories
60 in many cases.
28 - include sys/syscall.h instead of plain syscall.h. 61 - include sys/syscall.h instead of plain syscall.h.
29 - check for io watcher loops in ev_verify, check for the most 62 - check for io watcher loops in ev_verify, check for the most
30 common reported usage bug in ev_io_start. 63 common reported usage bug in ev_io_start.
31 - chose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET. 64 - choose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET.
32 - always use WSASend/WSARecv directly on windows, hoping that this 65 - always use WSASend/WSARecv directly on windows, hoping that this
33 works in all cases (unlike read/write/send/recv...). 66 works in all cases (unlike read/write/send/recv...).
67 - try to detect signals around a fork faster (test program by
68 Denis Bilenko).
69 - work around recent glibc versions that leak memory in realloc.
70 - rename ev::embed::set to ev::embed::set_embed to avoid clashing
71 the watcher base set (loop) method.
72 - rewrite the async/signal pipe logic to always keep a valid fd, which
73 simplifies (and hopefully correctifies :) the race checking
74 on fork, at the cost of one extra fd.
75 - add fat, msdos, jffs2, ramfs, ntfs and btrfs to the list of
76 inotify-supporting filesystems.
77 - move orig_CFLAGS assignment to after AC_INIT, as newer autoconf
78 versions ignore it before
79 (https://bugzilla.redhat.com/show_bug.cgi?id=908096).
80 - add some untested android support.
81 - enum expressions must be of type int (reported by Juan Pablo L).
