Revision history for libev, a high-performance and full-featured event loop.
TODO: ABI??? API????? Changes???
TODO: win32 write() to socket for signal handling
- ev_embed_stop did not correctly stop the watcher (very good
testcase by Vladimir Timofeev).
- applied win32 fixes by Michael Lenaghan (also James Mansion).
@ -19,6 +20,8 @@ TODO: ABI??? API????? Changes???
- new EV_CHILD_ENABLE and EV_SIGNAL_ENABLE configurable settings.
- update libev.m4 HAVE_CLOCK_SYSCALL test for newwer glibcs.
- add section on accept() problems to the manpage.
- rename EV_TIMEOUT to EV_TIMER.
- switch to two-digit minor version.

=item C<EV_TIMEOUT> replaced by C<EV_TIMER> in C<revents>
This is a simple rename - all other watcher types use their name
as revents flag, and now C<ev_timer> does, too.
Both C<EV_TIMER> and C<EV_TIMEOUT> symbols were present in 3.x versions
and continue to be present for the forseeable future, so this is mostly a
documentation change.
=item C<EV_MINIMAL> mechanism replaced by C<EV_FEATURES>
The preprocessor symbol C<EV_MINIMAL> has been replaced by a different
