On behalf of Twisted Matrix Laboratories, I am pleased to announce the release of Twisted 12.1.

107 tickets are closed by this release, with the following highlights:

* 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 for IReactorUNIX and an AMP argument using that feature.

* Support for IPv6 literals in connectTCP.

* Persistent connections support for the new HTTP client.

This is the last Twisted release supporting Python 2.5.
