3TODO: for next ABI/API change, consider moving EV__IOFDSSET into io->fd instead and provide a getter.
4TODO: document EV_TSTAMP_T

6 - the 4.31 timerfd code wrongly changes the priority of the signal
7 fd watcher, which is usually harmless unless signal fds are
8 also used (found via cpan tester service).
9 - the documentation wrongly claimed that user may modify fd and events
10 members in io watchers when the wqatcher was stopped
11 (found by b_jonas).
12 - new ev_io_modify mutator which changes only the events member,
13 which can be faster. also added ev::io::set (int events) method
14 to ev++.h.
15 - officially allow a zero events mask for io watchers. this should
16 work with older libev versions as well but was not officially
17 allowed before.
18 - do not wake up every minute when timerfd is used to detect timejumps.
19 - do not wake up every minute when periodics are disabled and we have
20 a monotonic clock.
21 - support a lot more "uncommon" compile time configurations,
22 such as ev_embed enabled but ev_timer disabled.
23 - use a start/stop wrapper class to reduce code duplication in
24 ev++.h and make it needlessly more c++-y.
25 - the linux aio backend is no longer compiled in by default.
26 - update to libecb version 0x00010008.

284.31 Fri Dec 20 21:58:29 CET 2019
29 - handle backends with minimum wait time a bit better by not
30 waiting in the presence of already-expired timers
31 (behaviour reported by Felipe Gasper).
32 - new feature: use timerfd to detect timejumps quickly,
33 can be disabled with the new EVFLAG_NOTIMERFD loop flag.
34 - document EV_USE_SIGNALFD feature macro.
35
364.30 (EV only)
37 - change non-autoconf test for __kernel_rwf_t by testing
38 LINUX_VERSION_CODE, the most direct test I could find.
39 - fix a bug in the io_uring backend that polled the wrong
40 backend fd, causing it to not work in many cases.
41
424.29 (EV only)
43 - add io uring autoconf and non-autoconf detection.
44 - disable io_uring when some header files are too old.
45
464.28 (EV only)
47 - linuxaio backend resulted in random memory corruption
48 when loop is forked.
49 - linuxaio backend might have tried to cancel an iocb
50 multiple times (was unable to trigger this).
51 - linuxaio backend now employs a generation counter to
52 avoid handling spurious events from cancelled requests.
53 - io_cancel can return EINTR, deal with it. also, assume
54 io_submit also returns EINTR.
55 - fix some other minor bugs in linuxaio backend.
56 - ev_tstamp type can now be overriden by defining EV_TSTAMP_T.
57 - cleanup: replace expect_true/false and noinline by their
58 libecb counterparts.
59 - move syscall infrastructure from ev_linuxaio.c to ev.c.
60 - prepare io_uring integration.
61 - tweak ev_floor.
62 - epoll, poll, win32 Sleep and other places that use millisecond
63 reslution now all try to round up times.
64 - solaris port backend didn't compile.
65 - abstract time constants into their macros, for more flexibility.
66
674.27 Thu Jun 27 22:43:44 CEST 2019
68 - linux aio backend almost completely rewritten to work around its
69 limitations.
70 - linux aio backend now requires linux 4.19+.
71 - epoll backend now mandatory for linux aio backend.
72 - fail assertions more aggressively on invalid fd's detected
73 in the event loop, do not just silently fd_kill in case of
74 user error.
75 - ev_io_start/ev_io_stop now verify the watcher fd using
76 a syscall when EV_VERIFY is 2 or higher.
77
784.26 (EV only)
79 - update to libecb 0x00010006.
80 - new experimental linux aio backend (linux 4.18+).
81 - removed redundant 0-ptr check in ev_once.
82 - updated/extended ev_set_allocator documentation.
83 - replaced EMPTY2 macro by array_needsize_noinit.
84 - minor code cleanups.
85 - epoll backend now uses epoll_create1 also after fork.
86
874.25 Fri Dec 21 07:49:20 CET 2018
88 - INCOMPATIBLE CHANGE: EV_THROW was renamed to EV_NOEXCEPT
89 (EV_THROW still provided) and now uses noexcept on C++11 or newer.
3 - move the darwin select workaround highe rin ev.c, as newre versions of 90 - move the darwin select workaround higher in ev.c, as newer versions of
4 darwin managed to break their broken select even more. 91 darwin managed to break their broken select even more.
5 - ANDROID => __ANDROID__ (reported by enh@google.com). 92 - ANDROID => __ANDROID__ (reported by enh@google.com).
6 - disable epoll_create1 on android because it has broken header files 93 - disable epoll_create1 on android because it has broken header files
7 and google is unwilling to fix them (reported by enh@google.com). 94 and google is unwilling to fix them (reported by enh@google.com).
95 - avoid a minor compilation warning on win32.
96 - c++: remove deprecated dynamic throw() specifications.
97 - c++: improve the (unsupported) bad_loop exception class.
98 - backport perl ev_periodic example to C, untested.
99 - update libecb, biggets change is to include a memory fence
100 in ECB_MEMORY_FENCE_RELEASE on x86/amd64.
101 - minor autoconf/automake modernisation.

11 didn't have the right version in ev.h, even though the cvs-tagged 105 didn't have the right version in ev.h, even though the cvs-tagged
12 version did have the right one (reported by Ales Teska). 106 version did have the right one (reported by Ales Teska).
