 Revision history for Perl extension EV
 
-Changes marked with (libev) are changes in libev, and have more
+Changes marked with (libev) are changes in libev, and might have more
 documentation in the libev Changes file.
 
+	- the enable assertion makefile question failed to enable
+          assertions due to a typo.
+	- try harder to avoid perl's assert () which does not actually
+          behave correctly.
+
+4.32 Fri Jan 24 14:21:35 CET 2020
+	- (libev) fixed a bug introduced in 4.31 when timerfds and signalfds were
+          used at the same time.
+        - (libev) 0 is now allowed as requested event mask in io watchers.
+        - (libev) once-per-minute wakeups will now be optimized away when
+          timerfds are available
+	- use the new ev_io_modify in EV::IO->events, instead of the potentially
+          slower ev_io_set.
+        - add a bunch of mutator methods, mostly untested(!): EV::Timer->repeat,
+          EV::Periodic->offset, EV::Periodic->interval,
+          EV::Periodic->reschedule_cb.
+        - minor optimisations and bugfixes.
+
+4.31 Fri Dec 20 21:57:00 CET 2019
+        - (libev) handle backends with minimum wait time a bit better by
+          not waiting in the presence of already-expired timers
+          (behaviour reported by Felipe Gasper).
+        - (libev) use timerfd to detect timejumps.
+        - (libev) new loop flag: EVFLAG_NOTIMERFD.
+
+4.30 Fri Nov 22 21:00:00 CET 2019
+	- (libev) use a different and hopefully even more portable
+          test to disable io_uring when header files are too old,
+          by directly testing LINUX_VERSION_CODE.
+        - (libev) fix a bug in the io_uring backend that polled the wrong
+          backend fd, causing it to not work in many cases.
+
+4.29 Fri Nov 22 15:34:29 CET 2019
+	- (libev) add io uring autoconf and non-autoconf detection,
+          the latter of which should disable io_uring compilation
+          on old systems.
+
+4.28 Tue Nov 19 13:55:39 CET 2019
+	- (libev) fix ev_port backend, thanks to David H. Gutteridge for
+        - (libev) many bugfixes in linuxaio backend.
+        - (libev) experimental io uring interface.
+          reminding me to actually release the fix.
+	- try to name ev.h more explicitly, to hopefully improve portability.
+        - opportunistically round up wait times for poll and epoll backend,
+          to avoid unnecessary loop iterations.
+        - add build dependency on ev_linuxaio.c.
+        - quickly (re)-ported to minix 3.3 before minix crashed again.
+
+4.27 Thu Jun 27 09:39:58 CEST 2019
+	- (libev) completely rewritten linuxaio backend, maybe
+          usable as a general-use backend.
+	- (libev) use more aggressive assertions to catch
+          more usage errors.
+	- allow users to re-enable assert() in case it is disabled
+          by perl (which is typically the case).
+
+4.26 Mon Jun 24 23:39:40 CEST 2019
+	- (libev) included experimental linux aio backend.
+        - allow the linux aio backend to be used by default
+          only when explicitly configured during Makefile.PL time.
+
+4.25 Fri Dec 21 08:04:26 CET 2018
+	- (libev) updated to libev 4.25, minor fixes and enhancements.
+	- document the requirement to "use EV" when using EV::MakeMaker.
+	- only use __register_atfork with glibc and uclibc, as musl
+          defines __linux__, but doesn't implement the linux standard
+          base ABI, nor makes itself detectable via a macro, both apparently
+          by design, winning the "broken by design 2016 award" - well done.
+        - correct EV::periodic example 24h after midnight -> one day after
+          midnight (reported by Felix Ostmann).
+
+4.22 Sun Dec 20 02:34:39 CET 2015
+        - (libev) when epoll detects unremovable fds in the fd set, rebuild
+          only the epoll descriptor, not the signal pipe, to avoid
+          SIGPIPE in ev_async_send. This doesn't solve it on fork,
+          so document what needs to be done in ev_loop_fork
+          (analyzed by Benjamin Mahler).
+        - (libev) remove superfluous sys/timeb.h include on win32
+          (analyzed by Jason Madden).
+        - updated libecb.
+
 4.21 Mon Jul 13 21:47:33 CEST 2015
 	- allow argument in timer->again.
         - document timer->remaining.
