Among the 106 tickets closed since our last release, you can find:

• The revival of the kqueue reactor for BSD platforms.
• epoll is now the default reactor under Linux after a fix to handle files on stdin/stdout.
• New reactors supporting GTK3 and GObject-Introspection.
• Several enhancements regarding file descriptors passing: systemd support for servers, ability to send and receive file descriptors across Unix sockets, and an AMP argument using that feature.
• Support for IPv6 literals in connectTCP.
• Persistent connections support for the new HTTP client.

This will be the last release supporting Python 2.5. Please give it a round of tests to help make a great release!
