+
+Cowboy `2.4.0` has been released!
+
+Numerous HTTP/2 options have been added to control
+the HTTP/2 SETTINGS and general behavior of HTTP/2
+connections. The options for initial window sizes,
+maximum frame sizes or compression table sizes
+might be of interest for optimizing the performance
+of HTTP/2 connections.
+
+Experimental support for Websocket over HTTP/2 was
+added. Note that browsers do not currently support
+it. The only browser with partial support is Google
+Chrome 67 (dev build) started with a specific flag.
+As a result it's disabled by default in Cowboy too.
+
+All of Cowboy's RFC7540 tests and all of the h2spec
+test suite cases now pass. There are still parts
+that are not implemented (the priority mechanisms
+for example) and edge cases that are not covered,
+however, so the HTTP/2 support can still be improved.
+
+A complete
+list of changes can be found in the migration guide:
+https://ninenines.eu/docs/en/cowboy/2.4/guide/migrating_from_2.3/[Migrating from Cowboy 2.3 to 2.4].

+You can donate to this project via

+These funds are used to pay for additional servers for
+testing. A new server was added this month and allows
+me to test with additional Linux distributions Alpine,
+CentOS and Debian. Thanks in advance!
+
+As usual, feedback is appreciated, and issues or
+questions should be sent via Github tickets. Thanks!
