 Changes marked with (libev) are changes in libev, and have more
 documentation in the libev Changes file.
 
+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.
+	- EV::run now returns a boolean.
+        - API version 5:1.
+        - document that cleanup watchers are not available via perl.
+        - cast I32 to int in error message printf.
+        - remove dependencies on librt and libpthreads on GNU/Linux.
+
+4.11 Sat Feb  4 19:56:26 CET 2012
+	- (libev) implement memory fences for (obsolete) llvm-gcc.
+
 4.10 Thu Jan 19 18:54:23 CET 2012
         - (libev) fix a race where the workaround against the epoll fork
           bugs caused signals to not be handled anymore.
