Update to 15.0.0:

Twisted Core 15.0.0 (2015-01-24)
================================

Features
--------
 - twisted.internet.protocol.ClientFactory (and subclasses) may now
   return None from buildProtocol to immediately close the connection.
   (#710)
 - twisted.trial.unittest.SynchronousTestCase.assertRaises can now
   return a context manager. (#5339)
 - Implementations of
   twisted.internet.interfaces.IStreamClientEndpoint included in
   Twisted itself will now handle None being returned from the client
   factory's buildProtocol method by immediately closing the
   connection and firing the waiting Deferred with a Failure. (#6976)
 - inlineCallbacks now supports using the return statement with a
   value on Python 3 (#7624)
 - twisted.spread.banana.Banana.sendEncoded() now raises a more
   informative error message if the user tries to encode objects of
   unsupported type. (#7663)

Bugfixes
--------
 - twisted.internet.interfaces.IReactorMulticast.listenMultiple works
   again RHEL 6's python 2.6. (#7159)
 - Allow much more of the code within Twisted to use ProcessEndpoint
   by adding IPushProducer and IConsumer interfaces to its resulting
   transport. (#7436)
 - twisted.internet.ssl.Certificate(...).getPublicKey().keyHash() now
   produces a stable value regardless of OpenSSL version.
   Unfortunately this means that it is different than the value
   produced by older Twisted versions. (#7651)
 - twisted.python.reflect.safe_str on Python 3 converts utf-8 encoded
   bytes to clean str instead of "b'a'" (#7660)
 - twisted.spread.banana.Banana now raises NotImplementedError when
   receiving pb messages without pb being the selected dialect (#7662)
 - The SSL server string endpoint parser
   (twisted.internet.endpoints.serverFromString) now constructs
   endpoints which, by default, disable the insecure SSLv3 protocol.
   (#7684)
 - The SSL client string endpoint parser
   (twisted.internet.endpoints.clientFromString) now constructs
   endpoints which, by default, disable the insecure SSLv3 protocol.
   (#7686)

Improved Documentation
----------------------
 - inlineCallbacks now has introductory documentation. (#1009)
 - The echoclient example now uses twisted.internet.task.react.
   (#7083)
 - Twisted Trial's how-to documentation now has a link to Twisted's
   contribution guidelines and has been reformatted. (#7475)
 - Fixed a path error in the make.bat file for building Sphinx
   documentation, so that it is now possible to build the documenation
   using make.bat on Windows. (#7542)

Deprecations and Removals
-------------------------
 - twisted.python.filepath.FilePath.statinfo was deprecated. (#4450)
 - twisted.internet.defer.deferredGenerator is now deprecated.
   twisted.internet.defer.inlineCallbacks should be used instead.
   (#6044)
 - Pickling twisted.internet.ssl.OptionSSLCertificationOptions and
   twisted.internet.ssl.Keypair is no longer supported. __getstate__
   and __setstate__ methods of these classes have been deprecated.
   (#6166)
 - twisted.spread.jelly's support for unjellying "instance" atoms is
   now deprecated. (#7653)

Twisted Conch 15.0.0 (2015-01-24)
=================================

Features
--------
 - The new APIs: twisted.conch.checkers.IAuthorizedKeysDB,
   twisted.conch.checkers.InMemorySSHKeyDB,
   twisted.conch.checkers.UNIXAuthorizedKeyFiles, and
   twisted.conch.checkers.SSHPublicKeyChecker have been added to
   provide functionality to check the validity of SSH public keys and
   specify where authorized keys are to be found. (#7144)

Deprecations and Removals
-------------------------
 - twisted.conch.checkers.SSHPublicKeyDatabase is now deprecated in
   favor of a twisted.conch.checkers.SSHPublicKeyChecker instantiated
   with a twisted.conch.checkers.UNIXAuthorizedKeyFiles. (#7144)
