On behalf of Twisted Matrix Laboratories, I am honoured to announce the release of Twisted 16.3.1. This is a security fix release, and is recommended for all users of Twisted. The fixes contained are: - Twisted's HTTP server, when operating over TLS, would not cleanly close sockets, causing it to build up CLOSE_WAIT sockets until it would eventually run out of file descriptors. For more information, check the NEWS file (link provided below). You can find the downloads at <https://pypi.python.org/pypi/Twisted <https://pypi.python.org/pypi/Twisted>> (or alternatively <http://twistedmatrix.com/trac/wiki/Downloads <http://twistedmatrix.com/trac/wiki/Downloads>>). The NEWS file is also available at <https://github.com/twisted/twisted/blob/twisted-16.3.2/NEWS <https://github.com/twisted/twisted/blob/twisted-16.3.2/NEWS>>. Many thanks to everyone who had a part in this release - the supporters of the Twisted Software Foundation, the developers who contributed code as well as documentation, and all the people building great things with Twisted! Twisted Regards, Amber Brown (HawkOwl)
