Twisted 16.6.0 Released

On behalf of Twisted Matrix Laboratories, I am honoured to announce the release of Twisted 16.6!

The highlights of this release are:
  • The ability to use "python -m twisted" to call the new twist runner,
  • More reliable tests from a more reliable implementation of some things, like IOCP,
  • Fixes for async/await & twisted.internet.defer.ensureDeferred, meaning it's getting closer to prime time!
  • ECDSA support in Conch & ckeygen (which has also been ported to Python 3),
  • Python 3 support for Words' IRC support and twisted.protocols.sip among some smaller modules,
  • Some HTTP/2 server optimisations,
  • and a few bugfixes to boot!
For more information, check the NEWS file (link provided below).

You can find the downloads on PyPI (or alternatively our website). The NEWS file is also available on GitHub.

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 16.5.0 Released

On behalf of Twisted Matrix Laboratories, I am honoured to announce the release of Twisted 16.5!

The highlights of this release are:

  • Deferred.addTimeout, for timing out your Deferreds! (contributed by cyli, reviews by adiroiban, theisencouple, manishtomar, markrwilliams)
  • yield from support for Deferreds, in functions wrapped with twisted.internet.defer.ensureDeferred. This will work in Python 3.4, unlike async/await which is 3.5+ (contributed by hawkowl, reviews by markrwilliams, lukasa).
  • The new asyncio interop reactor, which allows Twisted to run on top of the asyncio event loop. This doesn't include any Deferred-Future interop, but stay tuned! (contributed by itamar and hawkowl, reviews by rodrigc, markrwilliams)
  • twisted.internet.cfreactor is now supported on Python 2.7 and Python 3.5+! This is useful for writing pyobjc or Toga applications. (contributed by hawkowl, reviews by glyph, markrwilliams)
  • twisted.python.constants has been split out into constantly on PyPI, and likewise with twisted.python.versions going into the PyPI package incremental. Twisted now uses these external packages, which will be shared with other projects (like Klein). (contributed by hawkowl, reviews by glyph, markrwilliams)
  • Many new Python 3 modules, including twisted.pair, twisted.python.zippath, twisted.spread.pb, and more parts of Conch! (contributed by rodrigc, hawkowl, glyph, berdario, & others, reviews by acabhishek942, rodrigc, & others)
  • Many bug fixes and cleanups!
  • 260+ closed tickets overall.

You can find the downloads on PyPI (or alternatively our website). The NEWS file is also available on GitHub.

Twisted 16.4.0 Released

On behalf of Twisted Matrix Laboratories, I am honoured to announce the release of Twisted 16.4.0.

The highlights of this release are:
  • twist, a new command line tool for running Twisted plugins, similar to twistd but with a simpler, cleaner interface.
  • A new interface for Protocols, IHandshakeListener, which tells Twisted to tell the Protocol when the TLS handshake has been completed.
  • async/await support for Deferreds, allowing you to write Python 3.5+ coroutines using Twisted
  • Trial can be invoked with "python -m twisted.trial".
  • All Twisted executables (trial, twistd, etc) are now Setuptools console scripts, meaning they will work much better on Windows.
  • 35+ more modules ported to Python 3, and many many cleanups on the way to Python 3 on Windows support.
  • All the security fixes of Twisted 16.3.1 + 16.3.2 (httpoxy, HTTP session identifier strengthening, HTTP+TLS consuming sockets)
  • 240+ closed tickets overall.
For more information, check the NEWS file (link provided below).

You can find the downloads on PyPI (or alternatively our website). The NEWS file is also available on GitHub.

PS: Twisted 16.4.1 will be coming soon after this with a patch mitigating SWEET32, by updating the acceptable cipher list.

Twisted 16.3.2 Released

On behalf of Twisted Matrix Laboratories, I am honoured to announce the release of Twisted 16.3.2.

This is a bug fix & security fix release, and is recommended for all users of Twisted. The fixes are:
  • A bugfix for a HTTP/2 edge case, (included in 16.3.1)
  • Fix for CVE-2008-7317 (generating potentially guessable HTTP session identifiers) (included in 16.3.1)
  • Fix for CVE-2008-7318 (sending secure session cookies over insecured connections) (included in 16.3.1)
  • Fix for CVE-2016-1000111 (http://httpoxy.org/) (included in 16.3.1)
  • 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 on PyPI (or alternatively our website). The NEWS file is also available at on GitHub.

Twisted 16.3 Released

On behalf of Twisted Matrix Laboratories, I am honoured to announce the release of Twisted 16.3.0.

The highlights of this release are:
  • The Git migration has happened, so we've updated our development documentation to match. We're now trialling accepting pull requests at github.com/twisted/twisted, so if you've ever wanted an excuse to contribute, now's the chance!
  • In our steady shedding of baggage, twisted.spread.ui, twisted.manhole (not to be confused with twisted.conch.manhole!), and a bunch of old and deprecated stuff from twisted.python.reflect and twisted.protocols.sip have been removed.
  • twisted.web's HTTP server now handles pipelined requests better -- it used to try and process them in parallel, but this was fraught with problems and now it processes them in series, which is less surprising to code that expects the Request's transport to not be buffered (e.g. WebSockets). There is also a bugfix for HTTP timeouts not working in 16.2.
  • Twisted now has HTTP/2 support in its web server! This is currently not available by default -- you will need to install hyper-h2, which is available in the [h2] setuptools extras. If you want to play around with it "pip install twisted[h2]" (on Python 2, a bugfix release will make it available on Python 3) .
  • 53 tickets closed overall, including cleanups that move us closer to a total Python 3 port.
For more information, check the NEWS file (link provided below).

You can find the downloads on PyPI (or alternatively our website). The NEWS file is also available on GitHub.

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 16.2 Released

On behalf of Twisted Matrix Laboratories, I am honoured to announce the release of Twisted 16.2!

Just in time for PyCon US, this release brings a few headlining features (like the haproxy endpoint) and the continuation of the modernisation of the codebase. More Python 3, less deprecated code, what's not to like?
  • twisted.protocols.haproxy.proxyEndpoint, a wrapper endpoint that gives some extra information to the wrapped protocols passed by haproxy;
  • Migration of twistd and other twisted.application.app users to the new logging system (twisted.logger);
  • Porting of parts of Twisted Names' server to Python 3;
  • The removal of the very old MSN client code and the deprecation of the unmaintained ICQ/OSCAR client code;
  • More cleanups in Conch in preparation for a Python 3 port and cleanups in HTTP code in preparation for HTTP/2 support;
  • Over thirty tickets overall closed since 16.1.
For more information, check the NEWS file (link provided below).

You can find the downloads on PyPI (or alternatively our website). The NEWS file is also available on GitHub.

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 16.1 Released

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 on PyPI (or alternatively our website). The NEWS file is also available on GitHub.
