 Revision history for libev, a high-performance and full-featured event loop.
 
-TODO: signal mask problem documentation
+TODO: ev_loop_prefork hint?
 TODO: ev_loop_wakeup
+TODO: confusion about threads ongiong
+TODO: not_blocked flag.

+	- change the default periodic reschedule function to hopefully be more
+          exact and correct even in corner cases or in the far future.
+        - document reasonable ranges for interval and offset.
+        - 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.

+	- 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).
