 Changes marked with (libev) are changes in libev, and have more
 documentation in the libev Changes file.
 
+4.27
+	- allow users to re-enable assert() in case it is disabled
+          by perl (which is typically the case).
+	- (libev) completely rewritten linuxaio backend, maybe
+          usable as a general-use backend.
+	- (libev) use more aggressive assertions to catch
+          more usage errors.
+
+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.
+        - document default repeat value for timer->set.
+
+4.20 Sat Jun 20 13:07:34 CEST 2015
+        - added stability canary support.
+	- truly rely on automatic configuration for clock_gettime and others.
+          unfortunately, this doesn't help with activeperl and similar perls,
+          which define _POSIX_TIMERS without actually implementing any of it.
+        - (libev, ecb) make it compile as C++ again.
+        - (libev) fix a potential aliasing issue when accessing watcher cbs.
+
+4.18 Sat Sep  6 20:37:23 CEST 2014
+	- use slightly better weay to find includes, to support multiarch
+          on newer perls.
+
+4.17 Fri Apr 11 06:22:38 CEST 2014
+	- perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
+          without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
+          in 5.18. What's so attractive about giving a shit about backwards
+          compatibility - I will never understand.
+
+4.16 Sat Mar  8 16:49:05 CET 2014
 	- make sure EV::CHECK is available at all times.
         - avoid a spurious warning when perl -w overrides "no warnings".
+        - use perl's signal implementation on WIN32.
+        - ensure extern "C" function pointers are used for externally-visible
+          pointers.
+	- (libev) mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
+        - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
+        - (libev) in the absence of autoconf, do not use the clock syscall
+          on glibc >= 2.17 (avoids the syscall AND -lrt on systems
+          doing clock_gettime in userspace).
+        - (ecb) work around memory barriers and volatile apparently both being
+          broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).
 
 4.15 Fri Mar  1 12:15:53 CET 2013
 	- (libev) upgrade to 4.15 - too many changes to list.
