 Revision history for Perl extension EV
 
+Changes marked with (libev) are changes in libev, and have more
+documentation in the libev Changes file.
+
+4.00
+	- fix a bug where inotify usage would parse the same event
+          multiple times, causing various forms of breakage.
+	- greatly reduce stack usage for inotify (8kb to <0.5kb).
+        - renamed loop_verify to verify, loop_count to iteration and
+          loop_depth to depth.
+        - expose ev_depth and ev_verify via the XS API.
+        - (libev) ev_embed_stop did not correctly stop the watcher.
+        - (libev) disable poll backend on AIX.
+        - (libev) rename EV_TIMEOUT to EV_TIMER.
+        - (libev) add section on accept() problems to the manpage.
+        - (libev) no child watchers on win32.
+        - make code more aliasing compliant, in case perl is ever
+          translated to C.
+        - document the EV::CHECK runtime unavailability.
+        - ported to minix 3.1.7.
+
+3.9  Thu Dec 31 07:59:59 CET 2009
+	- disable t/07* under automatic testing.
+        - increase t/09* timeouts as netbsd has *horribly* broken
+          select/kevent that *usually* sleep >>0.6s instead of 0.3.
+        - add constants EV::FLAG_NOSIGFD, EV::FLAG_NOINOTIFY and
+          EV::BACKEND_ALL.
+        - (libev) signalfd is no longer used by default.
+	- (libev) backport inotify code to C89.
+        - (libev) inotify file descriptors could leak into child processes.
+        - (libev) ev_stat watchers could keep an errornous extra ref on the loop.
+        - (libev) take advantage of inotify_init1, if available.
+        - (libev) the signal handling pipe wasn't always initialised under windows.
+        - changed minimum glibc requirement from glibc 2.9 to 2.7, for signalfd.
+        - (libev) only replace ev_stat.prev when we detect an actual difference.
+
+3.8  Sun Aug  9 15:30:10 CEST 2009
+	- implement $loop->signal/signal_ns.
+        - (libev) incompatible change: do not necessarily reset signal
+          handler to SIG_DFL when a sighandler is stopped.
+        - (libev) ev_default_destroy did not properly free or zero some
+          members, potentially causing crashes and memory corruption on
+          repated ev_default_destroy/ev_default_loop calls.
+	- (libev) take advantage of signalfd on GNU/Linux systems.
+        - (libev) document that the signal mask might be in an unspecified
+          state when using libev's signal handling.
+        - (libev) take advantage of some GNU/Linux calls to set
+          cloexec/nonblock on fd creation, to avoid race conditions.
+        - implement internal glue code to interface more efficiently
+          with AnyEvent.
+
 3.7  Fri Jul 17 16:49:16 CEST 2009
 	- add EV::loop_verify and EV::loop_depth.
         - use output filehandle for i/o watchers waiting
