 .. towncrier release notes start
 
-Twisted 21.2.0.rc1 (2021-02-14)
-===============================
-
-Features
---------
-
-- The enableSessions argument to twisted.internet.ssl.CertificateOptions now
-  actually enables/disables OpenSSL's session cache.  Also, due to
-  session-related bugs, it defaults to False. (#9583)
-- twisted.internet.defer.inlineCallbacks and ensureDeferred will now associate a contextvars.Context with the coroutines they run, meaning that ContextVar objects will maintain their value within the same coroutine, similarly to asyncio Tasks. This functionality requires Python 3.7+, or the contextvars PyPI backport to be installed for Python 3.5-3.6. (#9719, #9826)
-- twisted.internet.defer.Deferred.fromCoroutine has been added. This is similar to the existing ensureDeferred function, but is named more consistently inside Twisted and does not pass through Deferreds. (#9825)
-- trial now allows the @unittest.skipIf decorator to specify that an entire test class should be skipped. (#9829)
-- The twisted.python.deprecate.deprecatedKeywordParameter decorator can be used to mark a keyword paramater of a function or method as deprecated. (#9844)
-- Projects using Twisted can now perform type checking against a Twisted
-  installation, for example using mypy. (#9908)
-- twisted.python.util.InsensitiveDict now fully implements MutableMapping. (#9919)
-- Python 3.8 is now tested and supported. (#9955)
-- Support a coroutine function in twisted.internet.task.react (#9974)
-
-
-Bugfixes
---------
-
-- twisted.web.twcgi.CGIProcessProtocol.processEnded(...) now handles an already-finished request, for example when request.connectionLost(...) was called previously. (#9468)
-- Twisted's dependency on PyHamcrest has been moved from the base package to the new "test" extra. Consequently the test extra must be installed for Twisted's test suite to pass. (#9509)
-- Fixed serialization of timedelta, date, and time objects in twisted.spread. (#9716)
-- twisted.internet.asyncioreactor.AsyncioSelectorReactor now raises an exception if instantiated with an event loop which is not compatible with asyncio.SelectorEventLoop. This fixes the AsyncioSelectorReactor in Python 3.8+ on Windows, where in bp-34687 the default Windows asyncio event loop was changed to ProactorEventLoop.  Applications that use AsyncioSelectorReactor on Windows with Python 3.8+ must call asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy()) before instantiating and running AsyncioSelectorReactor. (#9766)
-- twisted.internet.process.registerReapProcessHandler and ._BaseProcess.reapProcess will no longer raise a TypeError when processing a None PID (#9775)
-- INotify will close its file descriptor if a directory is automatically removed by twisted from the watchlist because it's deleted, avoiding orphaned filedescriptors. (#9777)
-- DelayedCall.reset() is now working properly with asyncioreactor (#9780)
-- AsyncioSelectorReactor.seconds() now correctly returns an epoch time. (#9787)
-- The _connDone parameter has been removed from twisted.internet.abstract.FileDescriptor.loseConnection()'s signature in order to match the signature in the base class twisted.internet._newtls.ConnectionMixin loseConnection(). (#9849)
-- The Gtk3 reactor now runs on Wayland-only sessions (#9904)
-- Descriptive error messages from twisted.internet.error are now present when running with 'python -OO'. (#9918)
-- Comparator methods such as __eq__() now always return NotImplemented for uncomparable types. (#9919)
-
-
-Improved Documentation
-----------------------
-
-- The narrative docs now contains the associated Twisted version and the date
-  when they were generated. (#3945)
-- The "Writing a twistd plugin" howto now explains how to deploy twistd plugins using Python packaging and pip (#9243)
--  (#9868, #9873, #9874)
-- Fix a typo in "Introduction to Deferreds" document. (#9948)
-- The Twisted Coding Standard has been changed to refer to The Black code style for guidelines regarding whitespace and line lengths. (#9957)
-- Exempt ``__repr__``, ``__slots__`` and other ``@attrs.define`` related changes from compatibility policy. (#9982)
-- Fix many docstring mistakes flagged by new sanity checks in pydoctor. (#10021)
-- Fix a few dozen broken links to API documentation pages. (#10057)
-
-
-Deprecations and Removals
--------------------------
-
-- twisted.cred.credentials.UsernameHashedPassword is now deprecated because it doesn't hash the password, causing it to return the wrong result. (#8368)
-- twisted.news is now removed from the codebase. (This module was never installed on Python 3.) (#9782)
-- Support for Python 2.7 has been removed. Twisted now supports only Python versions 3.5/3.6/3.7. (#9790)
-- twisted.pair.ethernet.IEthernetProtocol.addProto()'s interface was changed to match the existing implementations in the Twisted source code. (#9877)
-- twisted.python.filepath.FilePath.statinfo was deprecated in Twisted 15.0.0 and has now been removed. (#9881)
-- The parameters to twisted.internet.base.ReactorBase.addSystemEventTrigger(), twisted.internet.base.ReactorBase.callWhenRunning(), twisted.internet.base.ReactorBase.callLater(), twisted.internet.task.Clock.callLater() have been renamed to match the parameters defined in the following interfaces: twisted.internet.interfaces.IReactorCore, twisted.internet.interfaces.IReactorTime. (#9897)
-- Functions and types in twisted.python.compat that existed to support the transition from Python 2 to 3 have been deprecated. (#9922)
-- twisted.logger.LoggingFile.softspace has been deprecated. (#10042)
-- twisted.python.win32.WindowsError and FakeWindowsError have been deprecated. (#10053)
-- twisted.mail.pop3client has been renamed to twisted.mail._pop3client, since it has always been a private implementation module. (#10054)
