It's also now the primary web client in Twisted, with twisted.web.client.getPage being deprecated in favour of it and Treq.</div><div class="">- twisted.internet.ssl.CertificateOptions has had its `method` argument deprecated, in favour of the new raiseMinimumTo, lowerMaximumSecurityTo, and insecurelyLowerMinimumTo arguments, which take TLSVersion arguments. This allows you to better give a range of versions of TLS you wish to negotiate, rather than forcing yourself to any one version.</div><div class="">- twisted.internet.ssl.CertificateOptions will use OpenSSL's MODE_RELEASE_BUFFERS, which will let it free unused memory that was held by idle TLS connections.</div><div class="">- You can now call the new twist runner with `python -m twisted`.</div><div class="">- Conch has the beginnings of ECDH key exchange, and supports `hmac-sha2-384` in twisted.conch.ssh.</div><div class="">- Better Unicode support in twisted.internet.reactor.spawnProcess, especially on Windows on Python 3.6.</div><div class="">- More Python 3 porting in Conch, and more under-the-hood changes to facilitate a Twisted-wide jump to new-style classes only on Python 2 in 2018/2019. This release has also been tested on Python 3.6 on Linux.</div><div class="">- Lots of deprecated code removals, to make a sleeker, less confusing Twisted.</div><div class="">- 20+ closed tickets.</div><div class=""><br class=""></div><div class=""><div class="">You can get the tarball and the NEWS file at <a href="https://twistedmatrix.com/Releases/rc/16.7.0rc1/" class="">https://twistedmatrix.com/Releases/rc/16.7.0rc1/</a> , or you can try it out from PyPI:</div><div class=""><br class=""></div><div class=""> python -m pip install Twisted==16.7.0rc1</div><div class=""><br class=""></div><div class="">Please test it, and let me know how your applications fare, good or bad! If nothing comes up, 16.7 looks like it'll land just before the new year.</div></div><div class=""><br class=""></div><div class="">With festive hoots,</div><div class=""> Amber Brown</div><div class=""><br class=""></div></body></html>
