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.
