Twisted 22.1.0.rc1 (2022-01-26)

Features

• support Python 3.10b4 (#10224)
• Type annotations have been added to the twisted.python.fakepwd module. (#10287)
• twisted.conch.ssh now supports SSH extension negotiation (RFC 8308). (#10266)

Bugfixes

• twisted.conch now uses constant-time comparisons for MACs. (#8199)
• twisted.conch.ssh.filetransfer.FileTransferServer will now return an ENOENT error status if an SFTP client tries to close an unrecognized file handle. (#10293)
• twisted.internet.defer.inlineCallbacks has an improved type annotation, to avoid typing errors when it is used on a function which returns a non-None result. (#10231)
• revert changes to DelayedCall.__repr__ and LoopingCall.__repr__ (#10235)
• restore .whl building (#10236)
• SSHTransportBase.ssh_KEXINIT now uses the remote peer preferred MAC list for negotiation. In previous versions it was only using the local preferred MAC list. (#10241)
• The type annotation of the host parameter to twisted.internet.interfaces.IReactorTCP.connectTCP has been corrected from bytes to str. (#10251)
• Deprecated twisted.python.threading.ThreadPool.currentThread() in favor of threading.current_thread(). Switched twisted.python.threading.ThreadPool.currentThread() and twisted.python.threadable.getThreadID() to use threading.current_thread()to avoid the deprecation warnings introduced forthreading.currentThread()` in Python 3.10. (#10273)
• twisted.web.client.RedirectAgent and twisted.web.client.BrowserLikeRedirectAgent now properly remove sensitive headers when redirecting to a different origin. (#10294)
• trial.runner.filenameToModule now sets the correct module.name and sys.modules key (#10230)

Deprecations and Removals

• twisted.web.client.getPage, twisted.web.client.downladPage, and the associated implementation classes (HTTPPageGetter, HTTPPageDownloader, HTTPClientFactory, HTTPDownloader) have been removed because they do not segregate cookies by domain. They were deprecated in Twisted 16.7.0 in favor of twisted.web.client.Agent. GHSA-92x2-jw7w-xvvx. (#10295)

Improved Documentation

• twisted.internet.utils.runWithWarningsSupressed behavior of waiting on deferreds has been documented. (#10238)
• Sync API docs templates with pydoctor 21.9.0 release, using new theming capabilities. (#10267)
• Add type annotations for twisted.web.client.readBody. (#10269)
