 Revision history for libev, a high-performance and full-featured event loop.
 
-TODO: move some other examples to common idioms? combining watchers,
-thread usage, coroutine switch?
+TODO: ev_loop_wakeup
+TODO: EV_STANDALONE == NO_HASSEL (do not use clock_gettime in ev_standalone)
 
+4.11 Sat Feb  4 19:52:39 CET 2012
+	- INCOMPATIBLE CHANGE: ev_timer_again now clears the pending status, as
+          was documented already, but not implemented in the repeating case.
+        - new compiletime symbols: EV_NO_SMP and EV_NO_THREADS.
+	- fix a race where the workaround against the epoll fork bugs
+          caused signals to not be handled anymore.
+	- correct backend_fudge for most backends, and implement a windows
+          specific workaround to avoid looping because we call both
+          select and Sleep, both with different time resolutions.
+        - document range and guarantees of ev_sleep.
+        - document reasonable ranges for periodics interval and offset.
+        - rename backend_fudge to backend_mintime to avoid future confusion :)
+	- change the default periodic reschedule function to hopefully be more
+          exact and correct even in corner cases or in the far future.
+        - do not rely on -lm anymore: use it when available but use our
+          own floor () if it is missing. This should make it easier to embed,
+          as no external libraries are required.
+        - strategically import macros from libecb and mark rarely-used functions
+          as cache-cold (saving almost 2k code size on typical amd64 setups).
+        - add Symbols.ev and Symbols.event files, that were missing.
+        - fix backend_mintime value for epoll (was 1/1024, is 1/1000 now).
+        - fix #3 "be smart about timeouts" to not "deadlock" when
+          timeout == now, also improve the section overall.
+        - avoid "AVOIDING FINISHING BEFORE RETURNING" idiom.
+        - support new EV_API_STATIC mode to make all libev symbols
+          static.
+        - supply default CFLAGS of -g -O3 with gcc when original CFLAGS
+          were empty.
+
+4.04 Wed Feb 16 09:01:51 CET 2011
+	- fix two problems in the native win32 backend, where reuse of fd's
+          with different underlying handles caused handles not to be removed
+          or added to the select set (analyzed and tested by Bert Belder).
+	- do no rely on ceil() in ev_e?poll.c.
+        - backport libev to HP-UX versions before 11 v3.
+        - configure did not detect nanosleep and clock_gettime properly when
+          they are available in the libc (as opposed to -lrt).
+
+4.03 Tue Jan 11 14:37:25 CET 2011
+	- officially support polling files with all backends.
+	- support files, /dev/zero etc. the same way as select in the epoll
+          backend, by generating events on our own.
+        - ports backend: work around solaris bug 6874410 and many related ones
+          (EINTR, maybe more), with no performance loss (note that the solaris
+          bug report is actually wrong, reality is far more bizarre and broken
+          than that).
 	- define EV_READ/EV_WRITE as macros in event.h, as some programs use
           #ifdef to test for them.
+        - new (experimental) function: ev_feed_signal.
+        - new (to become default) EVFLAG_NOSIGMASK flag.
+        - new EVBACKEND_MASK symbol.
+        - updated COMMON IDIOMS SECTION.
