 Revision history for Perl extension EV
 
+        - further optimise epoll backend by adding a heuristic that
+          avoids EPOLL_CTL_DEL calls if possible.
 	- EV::signal->start was not async-signal safe.
         - fix some aliasing issues w.r.t. timers and periodics
           (not relevant for perl).
