We found a critical regression which might affect some applications that use a FileRegion, and had to cut the hot fix releases; Netty 4.0.23.Final and 4.1.0.Beta3

• #2407 - Use a better default value for server socket backlog
• #2768 - Fix an empty WebSocket close frame in hybi-00
• #2769 - Fix ClassCastException when trying to send a FileRegion
• #2771 - Fix a bug where EmbeddedChannel does not work with ChannelInitializer

You can also browse our issue tracker for the gory detail.

As always, please let us know if you find something to fix, improve, discuss, or even criticize. We love your feedback!
