 Revision history for libev, a high-performance and full-featured event loop.
 
-TODO: accept() documentation
+4.01 Fri Nov  5 21:51:29 CET 2010
+        - automake fucked it up, apparently, --add-missing -f is not quite enough
+          to make it update its files, so 4.00 didn't install ev++.h and
+          event.h on make install. grrr.
+        - ev_loop(count|depth) didn't return anything (Robin Haberkorn).
+        - change EV_UNDEF to 0xffffffff to silence some overzealous compilers.
+        - use "(libev) " prefix for all libev error messages now.

+4.00 Mon Oct 25 12:32:12 CEST 2010
+	- "PORTING FROM LIBEV 3.X TO 4.X" (in ev.pod) is recommended reading.
 	- ev_embed_stop did not correctly stop the watcher (very good
           testcase by Vladimir Timofeev).
+        - ev_run will now always update the current loop time - it erroneously
+          didn't when idle watchers were active, causing timers not to fire.
+        - fix a bug where a timeout of zero caused the timer not to fire
+          in the libevent emulation (testcase by Péter Szabó).
 	- applied win32 fixes by Michael Lenaghan (also James Mansion).
+	- replace EV_MINIMAL by EV_FEATURES.
+        - prefer EPOLL_CTL_ADD over EPOLL_CTL_MOD in some more cases, as it
+          seems the former is *much* faster than the latter.
+        - linux kernel version detection (for inotify bug workarounds)
+          did not work properly.
+        - reduce the number of spurious wake-ups with the ports backend.
         - remove dependency on sys/queue.h on freebsd (patch by Vanilla Hsu).
+        - do async init within ev_async_start, not ev_async_set, which avoids
+          an API quirk where the set function must be called in the C++ API
+          even when there is nothing to set.
+        - add (undocumented) EV_ENABLE when adding events with kqueue,
+          this might help with OS X, which seems to need it despite documenting
+          not to need it (helpfully pointed out by Tilghman Lesher).
+        - do not use poll by default on freebsd, it's broken (what isn't
+          on freebsd...).
+        - allow to embed epoll on kernels >= 2.6.32.
         - configure now prepends -O3, not appends it, so one can still
           override it.
+        - ev.pod: greatly expanded the portability section, added a porting
+          section, a description of watcher states and made lots of minor fixes.
         - disable poll backend on AIX, the poll header spams the namespace
           and it's not worth working around dead platforms (reported
           and analyzed by Aivars Kalvans).

+        - (experimental) ev_run/ev_default_loop/ev_break/ev_loop_new have now
