10 - fix a race where the workaround against the epoll fork bugs
11 caused signals to not be handled anymore.
12 - correct backend_fudge for most backends, and implement a windows
13 specific workaround to avoid looping because we call both
14 select and Sleep, both with different time resolutions.
15 - document range and guarantees of ev_sleep.
16 - document reasonable ranges for periodics interval and offset.
17 - rename backend_fudge to backend_mintime to avoid future confusion :)
18 - change the default periodic reschedule function to hopefully be more
19 exact and correct even in corner cases or in the far future.
20 - do not rely on -lm anymore: use it when available but use our
21 own floor () if it is missing. This should make it easier to embed,
22 as no external libraries are required.
23 - strategically import macros from libecb and mark rarely-used functions
24 as cache-cold (saving almost 2k code size on typical amd64 setups).
25 - add Symbols.ev and Symbols.event files, that were missing.
26
274.04 Wed Feb 16 09:01:51 CET 2011
28 - fix two problems in the native win32 backend, where reuse of fd's
29 with different underlying handles caused handles not to be removed
30 or added to the select set (analyzed and tested by Bert Belder).
31 - do no rely on ceil() in ev_e?poll.c.
32 - backport libev to HP-UX versions before 11 v3.
33 - configure did not detect nanosleep and clock_gettime properly when
34 they are available in the libc (as opposed to -lrt).
35
364.03 Tue Jan 11 14:37:25 CET 2011
37 - officially support polling files with all backends.
38 - support files, /dev/zero etc. the same way as select in the epoll
39 backend, by generating events on our own.
40 - ports backend: work around solaris bug 6874410 and many related ones
41 (EINTR, maybe more), with no performance loss (note that the solaris
42 bug report is actually wrong, reality is far more bizarre and broken
43 than that).
44 - define EV_READ/EV_WRITE as macros in event.h, as some programs use
45 #ifdef to test for them.
46 - new (experimental) function: ev_feed_signal.
47 - new (to become default) EVFLAG_NOSIGMASK flag.
48 - new EVBACKEND_MASK symbol.
49 - updated COMMON IDIOMS SECTION.
50
514.01 Fri Nov 5 21:51:29 CET 2010
52 - automake fucked it up, apparently, --add-missing -f is not quite enough
53 to make it update its files, so 4.00 didn't install ev++.h and
54 event.h on make install. grrr.
55 - ev_loop(count|depth) didn't return anything (Robin Haberkorn).
56 - change EV_UNDEF to 0xffffffff to silence some overzealous compilers.
57 - use "(libev) " prefix for all libev error messages now.
