+4.31
+	- handle backends with minimum wait time a bit better by not
+          waiting in the presence of already-expired timers
+          (behaviour reported by Felipe Gsper).
+
+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.
