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

34 - destroying a non-default loop would stop the global waitpid
35 watcher (Denis Bilenko).
36 - queueing pending watchers of higher priority from a watcher now invokes
37 them in a timely fashion (reported by Denis Bilenko).
12 - add throw() to all libev functions that cannot throw exceptions, for 38 - add throw() to all libev functions that cannot throw exceptions, for
13 further code size decrease when compiling for C++. 39 further code size decrease when compiling for C++.
14 - add throw () to callbacks that must not throw exceptions (allocator, 40 - add throw () to callbacks that must not throw exceptions (allocator,
15 syserr, loop acquire/release, periodic reschedule cbs). 41 syserr, loop acquire/release, periodic reschedule cbs).
16 - fix event_base_loop return code, add event_get_callback, event_base_new, 42 - fix event_base_loop return code, add event_get_callback, event_base_new,
17 event_base_get_method calls to improve libevent 1.x emulation and add 43 event_base_get_method calls to improve libevent 1.x emulation and add
18 some libevent 2.x funcitonality (based on a patch by Jeff Davey). 44 some libevent 2.x functionality (based on a patch by Jeff Davey).

29 the kqueue descriptor in the child. 55 the kqueue descriptor in the child.
56 - work around linux inotify not reporting IN_ATTRIB changes for directories
57 in many cases.
30 - include sys/syscall.h instead of plain syscall.h. 58 - include sys/syscall.h instead of plain syscall.h.
59 - check for io watcher loops in ev_verify, check for the most
60 common reported usage bug in ev_io_start.
61 - choose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET.
62 - always use WSASend/WSARecv directly on windows, hoping that this
63 works in all cases (unlike read/write/send/recv...).
64 - try to detect signals around a fork faster (test program by
65 Denis Bilenko).
66 - work around recent glibc versions that leak memory in realloc.
67 - rename ev::embed::set to ev::embed::set_embed to avoid clashing
68 the watcher base set (loop) method.
69 - rewrite the async/signal pipe logic to always keep a valid fd, which
70 simplifies (and hopefully correctifies :) the race checking
71 on fork, at the cost of one extra fd.
72 - add fat, msdos, jffs2, ramfs, ntfs and btrfs to the list of
73 inotify-supporting filesystems.
74 - move orig_CFLAGS assignment to after AC_INIT, as newer autoconf
75 versions ignore it before
76 (https://bugzilla.redhat.com/show_bug.cgi?id=908096).
77 - add some untested android support.
78 - enum expressions must be of type int (reported by Juan Pablo L).
