 Revision history for libev, a high-performance and full-featured event loop.
 
 TODO: revisit 59.x timer in the light of modern powersaving
-TODO: maybe use timerfd to detect time jumps on linux
 TODO: document EV_TSTAMP_T

-	- (libev) add io uring autoconf and non-autoconf detection,
-          the latter of which should disable io_uring compilation
-          on old systems.
+	- the new timerfd code wrongly changed the priority of ther signal
+          fd watcher, which is usuallys harmless unless signal fds are
+          also used (found via cpan tester service).

+	- handle backends with minimum wait time a bit better by not
+          waiting in the presence of already-expired timers
+          (behaviour reported by Felipe Gasper).
+        - new feature: use timerfd to detect timejumps quickly,
+          can be disabled with the new EVFLAG_NOTIMERFD loop flag.
+        - document EV_USE_SIGNALFD feature macro.
+
+4.30 (EV only)
+	- change non-autoconf test for __kernel_rwf_t by testing
+          LINUX_VERSION_CODE, the most direct test I could find.
+        - fix a bug in the io_uring backend that polled the wrong
+          backend fd, causing it to not work in many cases.
+
+4.29 (EV only)
+	- add io uring autoconf and non-autoconf detection.
+        - disable io_uring when some header files are too old.
