On behalf of Twisted Matrix Laboratories, I am honoured to announce the release of Twisted 16.1! This release is hot off the heels of 16.0 released last month, including some nice little tidbits. The highlights include: - twisted.application.internet.ClientService, a service that maintains a persistent outgoing endpoint-based connection -- a replacement for ReconnectingClientFactory that uses modern APIs; - A large (77% on one benchmark) performance improvement when using twisted.web's client on PyPy; - A few conch modules have been ported to Python 3, in preparation for further porting of the SSH functionality; - Full support for OpenSSL 1.0.2f and above; - t.web.http.Request.addCookie now accepts Unicode and bytes keys/values; - `twistd manhole` no longer uses a hard-coded SSH host key, and will generate one for you on the fly (this adds a 'appdirs' PyPI dependency, installing with [conch] will add it automatically); - Over eighteen tickets overall closed since 16.0. For more information, check the NEWS file (link provided below). You can find the downloads at https://pypi.python.org/pypi/Twisted (or alternatively http://twistedmatrix.com/trac/wiki/Downloads). The NEWS file is also available at https://github.com/twisted/twisted/blob/twisted-16.1.0/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!
