+	- 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).
+	- remove superfluous sys/timeb.h include on win32
+          (analyzed by Jason Madden).
+        - updated libecb.

+	- prefer noexcept over throw () with C++ 11.
+        - update ecb.h due to incompatibilities with c11.
+        - fix a potential aliasing issue when reading and writing
+          watcher callbacks.

+	- ev.h wasn't valid C++ anymore, which tripped compilers other than
+          clang, msvc or gcc (analyzed by Raphael 'kena' Poss). Unfortunately,
+          C++ doesn't support typedefs for function pointers fully, so the affected
+          declarations have to spell out the types each time.
+	- when not using autoconf, tighten the check for clock_gettime and related
+          functionality.
+

+	- events on files were not always generated properly with the
+          epoll backend (testcase by Assaf Inbal).
 	- mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
+        - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
+        - use a reasonable fallback for EV_NSIG instead of erroring out
+          when we can't detect the signal set size.
+        - 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).
+        - ensure extern "C" function pointers are used for externally-visible
+          loop callbacks (not watcher callbacks yet).
+        - (ecb) work around memory barriers and volatile apparently both being
+          broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).

         - destroying a non-default loop would stop the global waitpid
