Twisted 19.10.0:
Features
- twisted.trial.successResultOf, twisted.trial.failureResultOf, and
twisted.trial.assertNoResult accept coroutines as well as Deferreds.
Bugfixes
- Fixed circular import in twisted.trial.reporter, introduced in Twisted 16.0.0.
- The POP3 server implemented by twisted.mail.pop3 now accepts passwords that contain spaces.
- Incoming HTTP/2 connections will now not time out if they persist for longer than one minute.
- The serial extra now requires pywin32 on Windows enabling use of twisted.internet.serialport without specifying the windows_platform extra.
Bugfixes
- twisted.conch.ssh.keys now correctly writes the "iqmp" parameter in serialized RSA private keys as q^-1 mod p rather than p^-1 mod q.
Features
- twisted.web.server.Request will now use twisted.web.server.Site.getContentFile, if it exists, to get a file into which to write request content. If getContentFile is not provided by the site, it will fall back to the previous behavior of using io.BytesIO for small requests and tempfile.TemporaryFile for large ones.
Bugfixes
- twisted.web.client.FileBodyProducer will now stop producing when the Deferred returned by FileBodyProducer.startProducing is cancelled.
- The HTTP/2 server implementation now enforces TCP flow control on control frame messages and times out clients that send invalid data without reading responses. This closes CVE-2019-9512 (Ping Flood), CVE-2019-9514 (Reset Flood), and CVE-2019-9515 (Settings Flood). Thanks to Jonathan Looney and Piotr Sikora.

- Add new twisted.logger.capturedLogs context manager for capturing observed log events in tests.
- twisted.internet.base.PluggableResolverMixin, which implements the pluggable resolver interfaces for easier re-use in other reactors, has been factored out of ReactorBase.
- The PyPI page for Twisted has been enhanced to include more information and useful links.
Bugfixes

- twisted.internet.process does not fail on import when the process has more than 1024 file descriptors opened.
- Add the stackLevel keyword argument to twisted.logger.STDLibLogObserver._findCaller to fix an incompatibility with Python 3.8.
Improved Documentation
- Fix the incorrect docstring for twisted.python.components.Componentized.addComponent which stated that the function returned a list of interfaces, even though the function doesn't actually do so.
Deprecations and Removals
- twisted.test.proto_helpers has moved to twisted.internet.testing. twisted.test.proto_helpers has been deprecated.
- twisted.protocols.mice, deprecated since Twisted 16.0, has been removed.
- twisted.conch.insults.client and twisted.conch.insults.colors, deprecated since Twisted 10.1, have been removed.
- The __version__ attribute of Twisted submodules that were previously packaged separately, deprecated since Twisted 16.0, has been removed.
- Python 3.4 is no longer supported.
- twisted.python.compat.OrderedDict, an alias for collections.OrderedDict and deprecated since Twisted 15.5, has been removed.
Bugfixes
- t.c.ssh.connection.SSHConnection now fails channels that are in the process of opening when the connection is lost.
Features
- twisted.web.tap, the module that is run by `twist web`, now accepts --display-tracebacks to render tracebacks on uncaught exceptions.
Bugfixes
- twisted.web.http.Request.write after the channel is disconnected will no longer raise AttributeError.
- twisted.web.client.Agent.request() and twisted.web.client.ProxyAgent.request() now produce TypeError when the method argument is not bytes, rather than failing to generate the request.
- twisted.web.http.HTTPChannel no longer raises TypeError internally when receiving a line-folded HTTP header on Python 3.
- All HTTP clients in twisted.web.client now raise a ValueError when called with a method and/or URL that contain invalid characters. This mitigates CVE-2019-12387. Thanks to Alex Brasetvik for reporting this vulnerability.
- twisted.web.server.Site's instance variable displayTracebacks is now set to False by default.
Improved Documentation
- twisted.web.iweb.IRequest's "prepath" and "postpath" attributes, which have existed for a long time, are now documented.
- The documented type of t.w.iweb.IRequest's "method" and "uri" attributes on Python 3 has been corrected to match the implementation.
- t.w.iweb.IRequest's "args" attribute is now correctly documented to be bytes.
- The API documentation of twisted.web.iweb.IRequest and twisted.web.http.Request has been updated and extended to match the implementation.
Deprecations and Removals
- Passing a path argument to twisted.web.resource.Resource.putChild which is not of type bytes is now deprecated. In the future, passing a non-bytes argument to putChild will return an error.
- Passing --notracebacks/-n to twisted.web.tap, the module that is run by `twist web`, is now deprecated due to traceback rendering being disabled by default.
Features
- twisted.words.protocols.jabber.xmlstream.TLSInitiatingInitializer and twisted.words.protocols.jabber.client.XMPPClientFactory now take an optional configurationForTLS for customizing certificate options for StartTLS.
Bugfixes
- twisted.words.protocols.jabber.xmlstream.TLSInitiatingInitializer now properly verifies the server's certificate against platform CAs and the stream's domain, mitigating CVE-2019-12855.
Bugfixes
- twisted.names.client.Resolver will no longer infinite loop if it cannot bind a UDP port to use for resolving.
Twisted 19.2.0:
This is the final release that will support Python 3.4.
Features
- twisted.internet.ssl.CertificateOptions now uses 32 random bytes instead of an MD5 hash for the ssl session identifier context.
- DeferredLock and DeferredSemaphore can be used as asynchronous context
managers on Python 3.5+.
- t.i.b.BaseConnector has custom __repr__
- twisted.internet.ssl.optionsForClientTLS now supports validating IP addresses from the certificate subjectAltName
- Twisted's minimum Cryptography requirement is now 2.5.
Bugfixes

- twisted.python.failure.Failure.getTracebackObject now returns traceback objects whose frames can be passed into traceback.print_stack for better debugging of where the exception came from.
- twisted.internet.ssl.KeyPair.generate: No longer generate 1024-bit RSA keys by default. Anyone who generated a key with this method using the default value should move to replace it immediately.
- The message of twisted.internet.error.ConnectionAborted is no longer truncated.
- twisted.enterprise.adbapi.ConnectionPool.connect now logs only the dbapiName and not the connection arguments, which may contain credentials
- twisted.python.runtime.Platform.supportsINotify no longer considers the result of isDocker for its own result.
Improved Documentation
- The documentation for the the twisted.internet.interfaces.IConsumer, IProducer, and IPullProducer interfaces is more detailed.
- The errback example in the docstring of twisted.logger.Logger.failure has been corrected.
- The sample code in the "Twisted Web In 60 Seconds" tutorial runs on Python 3.
Features
- twisted.conch.ssh.keys can now read private keys in the new "openssh-key-v1" format, introduced in OpenSSH 6.5 and made the default in OpenSSH 7.8.
Bugfixes
- Conch now uses pyca/cryptography for Diffie-Hellman key generation and agreement.
Features
- twisted.web.client.HostnameCachingHTTPSPolicy was added as a new contextFactory option. The policy caches a specified number of twisted.internet.interfaces.IOpenSSLClientConnectionCreator instances to to avoid the cost of instantiating a connection creator for multiple requests to the same host.
Bugfixes
- twisted.web.http.Request.cookies, twisted.web.http.HTTPChannel.writeHeaders, and twisted.web.http_headers.Headers were all vulnerable to header injection attacks. They now replace linear whitespace ('\r', '\n', and '\r\n') with a single space. twisted.web.http.Reqeuest.cookies also replaces semicolons (';') with a single space.
- twisted.web.client.Request and twisted.web.client.HTTPClient were both vulnerable to header injection attacks. They now replace linear whitespace ('\r', '\n', and '\r\n') with a single space.
Features
- twisted.names.dns now has IRecord implementations for the SSHFP and TSIG record types.
Twisted 18.9.0:
Features
--------
twisted.internet._sslverify.ClientTLSOptions no longer raises IDNAError when given an IPv6 address as a hostname in a HTTPS URL.
The repr() of a twisted.internet.base.DelayedCall now encodes the same information as its str(), exposing details of its scheduling and target callable.
Python 3.7 is now supported.
Bugfixes
--------
twisted.logger.LogBeginner's default critical observer now prints tracebacks for new and legacy log system events through the use of the new eventAsText API. This API also does not raise an error for non-ascii encoded data in Python2, it attempts as well as possible to format the traceback.
Syntax error under Python 3.7 fixed for twisted.conch.manhole and twisted.main.imap4.
trial -j reports tracebacks on test failures under Python 3.
Properly format multi-byte and non-ascii encoded data in a traceback.
twisted.python.rebuild now functions on Python 3.7.
HTTP/2 server connections will no longer time out active downloads that take too long.
Improved Documentation
----------------------
Several minor formatting problems in the API documentation have been corrected.
The documentation of twisted.internet.defer.Deferred.fromFuture() has been updated to reflect upstream changes.
Deprecations and Removals
-------------------------
async keyword argument is deprecated in twisted.conch.manhole (ManholeInterpreter.write and Manhole.add) and in twisted.main.imap4.IMAP4Server.sendUntaggedResponse, isAsync keyword argument is introduced instead.
Twisted 18.7.0:
Features
--------
- Cancelling a Deferred returned by twisted.internet.defer.inlineCallbacks now cancels the Deferred it is waiting on.
- twisted.application.internet.ClientService now accepts a function to initialize or validate a connection before it is returned by the whenConnected method as the prepareConnection argument.
- Traceback generated for twisted.internet.defer.inlineCallbacks now includes the full stack of inlineCallbacks generators between catcher and raiser (before it only contained raiser's stack).
- Add optional cwd argument to twisted.runner.procmon.ProcMon.addProcess
- twisted.python.failure.Failure tracebacks generated by coroutines scheduled with twisted.internet.defer.ensureDeferred - i.e. any Deferred-awaiting coroutine - now contain fewer extraneous frames from the trampoline implementation, and correctly indicate the source of exceptions raised in other call stacks - i.e. the function that raised the exception. In other words: if you 'await' a function that raises an exception, you'll be able to see where the error came from.
Bugfixes
--------
- On UNIX-like platforms, Twisted attempts to recover from EMFILE when accepting connections on TCP and UNIX ports by shedding incoming clients.
- The documentation of IReactorTime.getDelayedCalls() has been corrected to indicate that the method returns a list, not a tuple.
- "python -m twisted web --help" now refers to "--listen" instead of the non-existing "--http"
- twisted.python.htmlizer.TokenPrinter now explicitly works on bytestrings.
- twisted.enterprise.adbapi.ConnectionPool.runWithConnection and runInteraction now use the reactor that is passed to ConnectionPool's constructor.
Improved Documentation
----------------------
- The Twisted Coding Standard now contains examples of how to mark up a feature as added in the next Twisted release.
Deprecations and Removals
-------------------------
- Deprecate direct introspection of ProcMon's processes: processes should not be directly accessed or pickled.
- twisted.internet.address.IPv4Address._bwHack and twisted.internet.address.UNIXAddress._bwHack, as well as the parameters to the constructors, deprecated since Twisted 11.0, have been removed.
Twisted 17.9.0:
Features
--------
- twisted.python.failure.Failure is now a new-style class which subclasses
BaseException.
- twisted.internet.posixbase.PosixReactorBase.adoptStreamPort and
twisted.internet.posixbase.PosixReactorBase.adoptStreamConnection now support
AF_UNIX SOCK_STREAM sockets.
-
- t.protocol.policies.TimeoutMixin.setTimeout and
t.protocol.policies.TimeoutProtocol.cancelTimeout (used in
t.protocol.policies.TimeoutFactory) no longer raise a
t.internet.error.AlreadyCancelled exception when calling them for an already
cancelled timeout.
- twisted.web.template.flatten now supports coroutines that yield Deferreds.
- twisted.web.client.HTTPConnectionPool passes the repr() of the endpoint to
the client protocol factory, and the protocol factory adds that to its own
repr(). This makes logs more useful.
- Python 3.6 is now supported
Bugfixes
--------
- twisted.python.logfile.BaseLogFile and subclasses now always open the file in
binary mode, and will process text as UTF-8.
- The `ssl:` endpoint now accepts `certKey` PEM files without trailing
newlines.
- Logger.__init__ sets the namespace to "<unknown>" instead of raising KeyError
when unable to determine the namespace from the calling context.
- twisted.internet._win32serialport updated to support pySerial 3.x and dropped
pySerial 2.x support.
- twisted.python.rebuild now works on Python 3.
- twisted.web.server.Request.notifyFinish will now once again promptly notify
applications of client disconnection (assuming that the client doesn't send a
large amount of pipelined request data) rather than waiting for the timeout;
this fixes a bug introduced in Twisted 16.3.0.
- twisted.web.guard.HTTPAuthSessionWrapper configured with
DigestCredentialFactory now works on both Python 2 and 3.
- Detect when we’re being run using “-m twisted” or “-m twisted.trial” and use
it to build an accurate usage message.
- twisted.protocols.tls.TLSMemoryBIOProtocol now allows unregisterProducer to
be called when no producer is registered, bringing it in line with other
transports.
- twisted.web web servers no longer print tracebacks when they timeout clients
that do not respond to TLS CLOSE_NOTIFY messages.
- twisted.mail.imap4 now works on Python 3.
- twisted.python.shortcut now works on Python 3 in Windows.
- Fix traceback forwarding with inlineCallbacks on python 3.
- twisted.mail.imap4.MessageSet now treats * as larger than every message ID,
leading to more consistent and robust behavior.
- The following plugins can now be used on Python 3 with twistd: dns, inetd,
portforward, procmon, socks, and words.
- twisted.internet._win32serialport now uses serial.serialutil.to_bytes() to
provide bytes in Python 3.
- twisted.internet.reactor.spawnProcess() now does not fail on Python 3 in
Windows if passed a bytes-encoded path argument.
- twisted.protocols.ident now works on Python 3.
- Ignore PyPy's implementation differences in base object class.
- twisted.python.test.test_setup now passes with setuptools 36.2.1
- twisted.internet._win32serialport SerialPort._clearCommError() no longer
raises AttributeError
- twisted.trial.unittest.SynchronousTestCase and
twisted.trial.unittest.TestCase now always run their tearDown methods, even
when a test method fails with an exception. They also flush all errors logged
by a test method before running another, ensuring the logged errors are
associated with their originating test method.
Bugfixes:
spawnProcess no longer opens an unwanted console on Windows
The transition to the hyperlink package adds IPv6 support to twisted.python.url.URL. This is now deprecated and new code should use hyperlink directly
twisted.logger now buffers only 200 events by default (reduced from 65536) while waiting for observers to be configured.
The transition of twisted.python.url to using the hyperlink package enables a URL.click() with no arguments (or 0-length string argument) to resolve dot segments in the path.
twisted.protocols.finger now works on Python 3.
TLS-related tests now pass when run with OpenSSL 1.1.0. This makes tests pass again on macOS and Windows, as cryptography 1.8 and later include OpenSSL 1.1.0.
UNIX socket endpoints now process all messages from recvmsg's ancillary data via twisted.internet.unix.Server.doRead/twisted.internet.unix.Client.doRead, while discarding and logging ones that don't contain file descriptors.
twisted.internet.endpoints.HostnameEndpoint and twisted.web.client.Agent work again with reactors that do not provide IReactorPluggableNameResolver. This undoes the changes that broke downstream users such as treq.testing. Note that passing reactors that do not provide IReactorPluggableNameResolver to either is deprecated.
A Python 3 Perspective Broker server which receives a remote call with keyword arguments from a Python 2 client will now decode any keys which are binary to strings instead of crashing. This fixes interoperability between Python 2 Buildbot clients and Python 3 Buildbot servers.
twisted.internet._threadedselect now works on both Python 2 and 3.
twisted.internet.interfaces.IResolverSimple implementers will now always be passed bytes, properly IDNA encoded if required, on Python 2. On Python 3, they will now be passed correctly IDNA-encoded Unicode forms of the domain, taking advantage of the idna library from PyPI if possible. This is to avoid Python's standard library (which has an out of date idna module) from mis- encoding domain names when non-ASCII Unicode is passed to it.
================================
Features
--------
- Added a new interface,
twisted.internet.interfaces.IHostnameResolver, which is an
improvement to twisted.internet.interfaces.IResolverSimple that
supports resolving multiple addresses as well as resolving IPv6
addresses. This is a native, asynchronous, Twisted analogue to
getaddrinfo. (bug-4362)
- twisted.web.client.Agent now uses HostnameEndpoint internally; as a
consequence, it now supports IPv6, as well as making connections
faster and more reliably to hosts that have more than one DNS name.
(bug-6712)
- twisted.internet.ssl.CertificateOptions now has the new constructor
argument 'raiseMinimumTo', allowing you to increase the minimum TLS
version to this version or Twisted's default, whichever is higher.
The additional new constructor arguments 'lowerMaximumSecurityTo'
and 'insecurelyLowerMinimumTo' allow finer grained control over
negotiated versions that don't honour Twisted's defaults, for
working around broken peers, at the cost of reducing the security
of the TLS it will negotiate. (bug-6800)
- twisted.internet.ssl.CertificateOptions now sets the OpenSSL
context's mode to MODE_RELEASE_BUFFERS, which will free the
read/write buffers on idle TLS connections to save memory. (bug-8247)
- trial --help-reactors will only list reactors which can be
imported. (bug-8745)
- twisted.internet.endpoints.HostnameEndpoint now uses the passed
reactor's implementation of
twisted.internet.interfaces.IReactorPluggableResolver to resolve
hostnames rather than its own deferToThread/getaddrinfo wrapper;
this makes its hostname resolution pluggable via a public API.
(bug-8922)
- twisted.internet.reactor.spawnProcess now does not emit a
deprecation warning on Unicode arguments. It will encode Unicode
arguments down to bytes using the filesystem encoding on UNIX and
Python 2 on Windows, and pass Unicode through unchanged on Python 3
on Windows. (bug-8941)
- twisted.trial._dist.test.test_distreporter now works on Python 3.
(bug-8943)
Bugfixes
--------
- trial --help-reactors will now display iocp and win32er reactors
with Python 3. (bug-8745)
- twisted.logger._flatten.flattenEvent now handles log_format being
None instead of assuming the value is always a string. (bug-8860)
- twisted.protocol.ftp is now Python 3 compatible (bug-8865)
- twisted.names.client.Resolver can now resolve names with IPv6 DNS
servers. (bug-8877)
- twisted.application.internet.ClientService now waits for existing
connections to disconnect before trying to connect again when
restarting. (bug-8899)
- twisted.internet.unix.Server.doRead and
twisted.internet.unix.Client.doRead no longer fail if recvmsg's
ancilliary data contains more than one file descriptor. (bug-8911)
- twist on Python 3 now correctly prints the help text when given no
plugin to run. (bug-8918)
- twisted.python.sendmsg.sendmsg no longer segfaults on Linux +
Python 2. (bug-8969)
- IHandshakeListener providers connected via SSL4ClientEndpoint will
now have their handshakeCompleted methods called. (bug-8973)
- The twist script now respects the --reactor option. (bug-8983)
- Fix crash when using SynchronousTestCase with Warning object which
does not store a string as its first argument (like
libmysqlclient). (bug-9005)
- twisted.python.compat.execfile() does not open files with the
deprecated 'U' flag on Python 3. (bug-9012)
Deprecations and Removals
-------------------------
- twisted.internet.ssl.CertificateOption's 'method' constructor
argument is now deprecated, in favour of the new 'raiseMinimumTo',
'lowerMaximumSecurityTo', and 'insecurelyLowerMinimumTo' arguments.
(bug-6800)
- twisted.protocols.telnet (not to be confused with the supported
twisted.conch.telnet), deprecated since Twisted 2.5, has been
removed. (bug-8925)
- twisted.application.strports.parse, as well as the deprecated
default arguments in strports.service/listen, deprecated since
Twisted 10.2, has been removed. (bug-8926)
- twisted.web.client.getPage and twisted.web.client.downloadPage have
been deprecated in favour of https://pypi.org/project/treq and
twisted.web.client.Agent. (bug-8960)
- twisted.internet.defer.timeout is deprecated in favor of
twisted.internet.defer.Deferred.addTimeout (bug-8971)
Twisted Core 16.6.0 (2016-11-17)
================================
Features
--------
- The twist script can now be run by invoking python -m twisted.
(#8657)

- twisted.persisted.dirdbm has been ported to Python 3. (#8888)
Bugfixes
--------
- twisted.internet.defer.Deferred now implements send, not __send__,
which means that it is now a conforming generator. (#8861)
- The IOCP reactor no longer transmits the contents of uninitialized
memory when writing large amounts of data. (#8870)
- Deferreds awaited/yielded from in a
twisted.internet.defer.ensureDeferred wrapped coroutine will now
properly raise exceptions. Additionally, it more closely models
asyncio.ensure_future and will pass through Deferreds. (#8878)
- Deferreds that are paused or chained on other Deferreds will now
return a result when yielded/awaited in a twisted.internet.defer
.ensureDeferred-wrapped coroutine, instead of returning the
Deferred it was chained to. (#8890)
Improved Documentation
----------------------
- twisted.test.proto_helpers is now explicitly covered by the
compatibility policy. (#8857)

- ckeygen has been ported to Python 3 (#8855)
Deprecations and Removals
-------------------------
- twisted.conch.ssh no longer uses gmpy, if available. gmpy is
unmaintained, does not have binary wheels for any platforms, and an
alternative for higher performance is available in the form of
PyPy. (#8079)
Twisted Web 16.6.0 (2016-11-17)
===============================
Features
--------
- twisted.web.server.Site's HTTP/2 server support now emits vastly
fewer WINDOW_UPDATE frames than previously. (#8681)
Bugfixes
--------

in the 100 range by discarding them, which is what RFC 7231
recommends doing. (#8885)
- twisted.web._http.H2Stream's getHost and getPeer implementations
now actually return the host and peer instead of None. (#8893)
Twisted Words 16.6.0 (2016-11-17)
=================================
Features
--------
- twisted.words.protocols.irc has been ported to Python 3 (#6320)
Twisted Core 16.5.0 (2016-10-28)
================================

timeouts of deferreds. (#5786)
- Perspective Broker (the twisted.spread package) has been ported to
Python 3 (#7598)
- 'yield from' can now be used on Deferreds inside generators, when
the generator is wrapped with
twisted.internet.defer.ensureDeferred. (#8087)
- twisted.internet.asyncioreactor has been added, which is a Twisted
reactor on top of Python 3.4+'s native asyncio reactor. It can be
selected by passing "--reactor=asyncio" to Twisted tools (twistd,
Trial, etc) on platforms that support it (Python 3.4+). (#8367)
- twisted.python.zippath now works on Windows with Python 3. (#8747)
- twisted.internet.cfreactor is ported to Python 3 and supported on
2.7 and 3.5+. (#8838)
Bugfixes
--------
- twisted.internet.test.test_iocp and twisted.internet.test.test_tcp
have been fixed to work under Python 3 with the Windows IOCP
reactor (#8631)
- Arguments to processes on Windows are now passed mbcs-encoded
arguments. This prevents process-related tests from hanging on
Windows with Python 3. (#8735)
- Client and server TLS connections made via the client TLS endpoint
and the server SSL endpoint, as well as any other code that uses
twisted.internet.ssl.CertificateOptions, no longer accept 3DES-
based cipher suites by default, to defend against SWEET32. (#8781)
- twisted.logger.jsonFileLogObserver no longer emits non-JSON
tracebacks into its file; additionally,
twisted.logger.formatEventAsClassicLogText now includes traceback
information for the log event it formats. (#8858)
- twisted.python.version now exports a version of Incremental that is
16.10.1 or higher, making t.p.v.Version package name comparisons
case-insensitive. (#8863)
- twisted.python.reflect.safe_str encodes unicode as ascii with
backslashreplace error handling on Python 2. (#8864)
Improved Documentation
----------------------
- The twisted.internet.interfaces.IProtocol.dataReceived() method
takes one parameter of type bytes. This has been clarified in the
doc string. (#8763)
Deprecations and Removals
-------------------------
- twisted.python.constants is deprecated in preference to constantly
on PyPI, which is the same code rolled into its own package.
(#7351)
- twisted.python.dist3 has been made private API. (#8761)
- When the source code is checked out, bin/trial is no longer in the
tree. Developers working on the Twisted source code itself should
either (1) run all tests under tox, or (2) run 'python setup.py
develop' to install trial before running any tests. (#8765)
- twisted.protocols.gps, deprecated since Twisted 15.2, has been
removed. (#8787)

Twisted Conch 16.5.0 (2016-10-28)
=================================
Features
--------
- SSH key fingerprints can be generated using base64 encoded SHA256
hashes. (#8701)
Bugfixes
--------
- SSHUserAuthServer does not crash on keyboard interactive
authentication when running on Python 3 (#8771)
- twisted.conch.insults.insults.ServerProtocol no longer corrupts a
client's display when attempting to set the cursor position, and
its ECMA-48 terminal manipulation works on Python 3. (#8803)

- #8495, #8511, #8715, #8851
Twisted Mail 16.5.0 (2016-10-28)
================================
Deprecations and Removals
-------------------------
- twisted.mail.protocols.DomainSMTP and DomainESMTP, deprecated since
2003, have been removed. (#8772)
Other
-----
- #6289, #8525, #8786, #8830

No significant changes have been made for this release.
Other
-----
- #8625, #8663
Twisted Pair 16.5.0 (2016-10-28)
================================
Features
--------
- twisted.pair has been ported to Python 3 (#8744)
Twisted Web 16.5.0 (2016-10-28)
===============================
Bugfixes
--------
- twisted.web.client.HTTPConnectionPool and anything that uses it,
like twisted.web.client.Agent, have had their logic for resuming
transports changed so that transports are resumed after state
machine transitions are complete, rather than before. This change
allows the HTTP client infrastructure to work with alternative HTTP
implementations such as HTTP/2 which may be able to deliver a
complete response synchronously when producing is resumed. (#8720)

=================================
No significant changes have been made for this release.
Other
-----
- #8360, #8460
Twisted Core 16.4.1 (2016-09-07)
================================
Features
--------
- Client and server TLS connections made via the client TLS endpoint
and the server SSL endpoint, as well as any other code that uses
twisted.internet.ssl.CertificateOptions, now support ChaCha20
ciphers when available from the OpenSSL on the system. (#8760)
Bugfixes
--------
- Client and server TLS connections made via the client TLS endpoint
and the server SSL endpoint, as well as any other code that uses
twisted.internet.ssl.CertificateOptions, no longer accept 3DES-
based cipher suites by default, to defend against SWEET32. (#8781)
Twisted Core 16.4.0 (2016-08-25)
================================
Features
--------
- Add twisted.application.twist, meant to eventually replace twistd
with a simpler interface. Add twisted.application.runner API,
currently private, which twist is built on. (#5705)
- The new interface IHandshakeListener that can be implemented by any
Protocol provides a callback that is called when the TLS handshake
has been completed, allowing Protocols to make decisions about the
TLS configuration before application data is sent. (#6024)
- twisted.python.syslog has been ported to Python 3. (#7957)
- twisted.internet.defer.ensureDeferred has been added, similar to
asyncio's ensure_future. Wrapping a coroutine (the result of a
function defined using async def, available only on Python 3.5+)
with it allows you to use the "await" keyword with Deferreds inside
the coroutine, similar to "yield" when using inlineCallbacks.
(#8088)
- twisted.internet.inotify have been ported to Python 3 (#8211)
- twisted.enterprise has been ported to Python 3. The third-party
pysqlite2 package has not been ported to Python 3, so any database
connector based on pysqlite2 cannot be used. Instead the sqlite3
module included with Python 3 should be used. (#8303)
- Scripts such as cftp, ckeygen, conch, mailmail, pyhtmlizer,
tkconch, twistd and trial have been updated to be setuptools
console scripts. (#8491)
- twisted.pair.raw and twisted.pair.rawudp have been ported to Python
3 (#8545)
- twisted.internet.baseprocess has been ported to Python 3. (#8546)
- twisted.python.dist has been ported to Python 3 (#8556)
- twisted.internet.interfaces.IOpenSSLContextFactory has been added,
which defines the interface provided both by the old-style
twisted.internet.ssl.ContextFactory class and the newer
twisted.interface.ssl.CertificateOptions class. This is a precursor
to formally deprecating the former class in favour of the latter.
(#8597)
- twisted.python.zipstream has been ported to Python 3 (#8607)
- Zip file entries returned by ChunkingZipFile.readfile() are now
context managers. (#8641)
- twisted.protocols.socks has been ported to Python 3 (#8665)
- twisted.spread.banana has been ported to Python 3 (#8667)
- Trial can now be invoked via "python -m twisted.trial". (#8712)
- twisted.protocols.postfix has been ported to Python 3 (#8713)
- twisted.protocols.wire and twisted.protocols.portforwarding have
been ported to Python 3 (#8717)
- twisted.protocols.stateful has been ported to Python 3 (#8718)
- twisted.protocols.memcache is now compatible with Python 3. (#8726)
- twisted.protocols.dict has been ported to Python 3 (#8732)
Bugfixes
--------
- pip install -e ".[dev]" now works on Python 3, but it will not
install twistedchecker or pydoctor, which have not yet been ported.
(#7807)
- twistd can now properly daemonize on Linux/Unix when run under
Python3 and will not hang indefinitely. (#8155)
- tox can now be used to run Twisted's tests on Windows (#8578)
- twisted.python.filepath.setContent() and
twisted.python.filepath.moveTo() now work on Windows with Python 3
(#8610)
- twisted.internet.win32eventreactor works on Python 3 in Windows
(#8626)
- The TLS payload buffer size was reduced in
twisted.protocols.tls.TLSMemoryBIOProtocol. This fixes writing of
very long strings using the TLSv1_1 method from the OpenSSL
library. (#8693)
- twisted.logger._flatten.flattenEvent() now does not crash if passed
a unicode string. (#8699)
- twisted.application.strports.service (and thus twistd) no longer
swallow asynchronous exceptions from IStreamServerEndpoint.listen.
(#8710)
- _twistd_unix now reports the name and encoded message of an
exception raised during daemonization on Python 2 and 3. (#8731)
- twisted.protocols.amp now handles floats on Python 3. Previously,
sending a float would raise a ValueError. (#8746)
Improved Documentation
----------------------
- Some broken links to xprogramming in the unit test documentation
have been fixed. (#8579)
- The Twisted Tutorial "The Evolution of Finger" has been updated to
use endpoints throughout. (#8588)
- Updated the mail examples to use endpoints and better TLS. (#8595)
- Changed the Twisted Web howto to use endpoints and modern TLS.
(#8596)
- Updated bug report URL in man pages. (#8600)
- In twisted.internet.udp.Port, write() takes a parameter of type
bytes. This is clarified in the docstring. (#8635)
- twisted.internet.interfaces.ITransport.write() and
twisted.internet.interfaces.ITransport.writeSequence() take bytes
parameters. (#8636)
- twisted.python.filepath.AbstractFilePath.getContent() returns
bytes. The docstring was updated to clarify this. (#8637)
- Updated release notes to reflect that 15.4 is the last version that
supported Python 2.6, not 15.5. (#8651)
- A missing space in defer.rst resulted in badly rendered output. The
space was added. (#8723)
Deprecations and Removals
-------------------------
- Dropped support for pyOpenSSL versions less than 16.0.0. (#8441)

Twisted Web 16.4.0 (2016-08-25)
===============================
Features
--------
- Twisted web HTTP/2 servers now time out HTTP/2 connections in the
same manner as HTTP/1.1 connections. (#8480)
Bugfixes
--------
- A bug in twisted.web.server.Site.makeSession which may lead to
predictable session IDs was fixed. Session IDs are now generated
securely using `os.urandom`. (#3460)
- twisted.web.server.Request.getSession will now, for a request sent
over HTTPS, set a "Secure" cookie, preventing the secure session
from being sent over plain-text HTTP. (#3461)
- If called multiple times, twisted.web.http.Request.setLastModified
now correctly observes the greatest supplied value. (#3807)
- The HTTP server now correctly times connections out. (broken in
16.2) (#8481)
- Twisted's HTTP/2 support no longer throws priority exceptions when
WINDOW_UDPATE frames are received after a response has been
completed. (#8558)
- twisted.web.twcgi.CGIScript will now not pass the "Proxy" header to
CGI scripts, as a mitigation to CVE-2016-1000111. (#8623)
- Twisted Web's HTTP/2 server can now tolerate streams being reset by
the client midway through a data upload without throwing
exceptions. (#8682)
- twisted.web.http.Request now swallows header writes on reset HTTP/2
streams, rather than erroring out. (#8685)
- twisted.web's HTTP/2 server now tolerates receiving WINDOW_UPDATE
frames for streams for which it has no outstanding data to send.
(#8695)
- twisted.web.http.HTTPChannel now resumes producing on finished,
non-persistent connections. This prevents HTTP/1 servers using TLS
from leaking a CLOSE_WAIT socket per request. (#8766)

from leaking a CLOSE_WAIT socket per request. (#8766)
Twisted Web 16.3.1 (2016-08-15)
===============================
Bugfixes
--------
- A bug in twisted.web.server.Site.makeSession which may lead to
predictable session IDs was fixed. Session IDs are now generated
securely using `os.urandom`. (#3460)
- twisted.web.server.Request.getSession will now, for a request sent

Twisted Core 16.3.0 (2016-07-05)
================================
Features
--------
- Defined a new interface, IProtocolNegotiationFactory, that can be
implemented by IOpenSSLClientConnectionCreator or
IOpenSSLServerConnectionCreator factories to allow them to offer
protocols for negotiation using ALPN or NPN during the TLS
handshake. (#8188)
- twisted.trial.unittest.SynchronousTestCase.assertRegex is now
available to provide Python 2.7 and Python 3 compatibility. (#8372)
Improved Documentation
----------------------
- Development documentation has been updated to refer to Git instead
of SVN. (#8335)
Deprecations and Removals
-------------------------
- twisted.python.reflect's deprecated functions have been removed.
This includes funcinfo (deprecated since Twisted 2.5), allYourBase
and accumulateBases (deprecated since Twisted 11.0), getcurrent and
isinst (deprecated since Twisted 14.0). (#8293)
- twisted.scripts.tap2deb and twisted.scripts.tap2rpm (along with the
associated executables), deprecated since Twisted 15.2, have now
been removed. (#8326)
- twisted.spread.ui has been removed. (#8329)
- twisted.manhole -- not to be confused with manhole in Conch -- has
been removed. This includes the semi-functional Glade reactor, the
manhole application, and the manhole-old twistd plugin. (#8330)
- twisted.protocols.sip.DigestAuthorizer, BasicAuthorizer, and
related functions have been removed. (#8445)

Twisted Names 16.3.0 (2016-07-05)
=================================
Bugfixes
--------
- twisted.names.client.Resolver as well as all resolvers inheriting
from twisted.names.common.ResolverBase can now understand DNS
answers that come back in a different case than the query. Example:
querying for www.google.com and the answer comes back with an A
record for www.google.COM will now work. (#8343)
Twisted Web 16.3.0 (2016-07-05)
===============================
Features
--------
- twisted.web.http.HTTPChannel now implements ITransport. Along with
this change, twisted.web.http.Request now directs all its writes to
the HTTPChannel, rather than to the backing transport. This change
is required for future HTTP/2 work. (#8191)
- twisted.web.http.HTTPChannel now has a HTTP/2 implementation which
will be used if the transport has negotiated using it through
ALPN/NPN (see #8188). (#8194)
Bugfixes
--------
- twisted.web.client.Agent and twisted.web.client.ProxyAgent now add
brackets to IPv6 literal addresses in the host header they send.
(#8369)
- The HTTP server now correctly times connections out. (broken in
16.2) (#8481)
Deprecations and Removals
-------------------------
- twisted.web would previously dispatch pipelined requests
simultaneously and queue the responses. This behaviour did not
enforce any of the guarantees required by RFC 7230 or make it
possible for users to enforce those requirements. For this reason,
the parallel dispatch of requests has been removed. Pipelined
requests are now processed serially. (#8320)
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.
Twisted Web 16.1.1 (2016-04-08)
===============================
Bugfixes
--------
- twisted.web.http.Request once again has a reference to the
HTTPFactory which created it, the absence of which was preventing
log messages from being created. (#8272)
Twisted Core 16.1.0 (2016-04-04)
================================
Features
--------
- twisted.application.internet.ClientService, a service that
maintains a persistent outgoing endpoint-based connection; a
replacement for ReconnectingClientFactory that uses modern APIs.
(#4735)
- Twisted now uses setuptools' sdist to build tarballs. (#7985)
Bugfixes
--------
- Twisted is now compatible with OpenSSL 1.0.2f. (#8189)

=================================
Features
--------
- twisted.conch.checkers is now ported to Python 3. (#8225)
- twisted.conch.telnet is now ported to Python 3. (#8228)
- twisted.conch.manhole_ssh.ConchFactory (used by `twistd manhole`)
no longer uses a hardcoded SSH server key, and will generate a
persistent one, saving it in your user appdir. If you use
ConchFactory, you will now need to provide your own SSH server key.

-----
- #8237, #8240
Twisted Web 16.1.0 (2016-04-04)
===============================

bytes arguments, with unicode arguments being encoded to UTF-8.
(#8067)
Bugfixes
--------
- twisted.web.util.DeferredResource no longer causes spurious
"Unhandled error in Deferred" log messages. (#8192)

bytes on both Python 2 and 3. (#8215)
Other
-----
- #8238
Twisted Core 16.0.0 (2016-03-10)
================================
Features
--------
- todo parameter for IReporter.addExpectedSuccess and
IReporter.addUnexpectedSuccess is no longer required. If not
provided, a sensible default will be used instead. (#4811)
- A new string endpoint type, "tls:", allows for properly-verified
TLS (unlike "ssl:", always matching hostname resolution with
certificate hostname verification) with faster IPv4/IPv6
connections. This comes with an accompanying function,
twisted.internet.endpoints.wrapClientTLS, which can wrap an
arbitrary client endpoint with client TLS. (#5642)
- twisted.python.filepath.makedirs accepts an ignoreExistingDirectory
flag which ignore the OSError raised by os.makedirs if requested
directory already exists. (#5704)
- twisted.protocols.amp has been ported to Python 3. (#6833)
- twisted.internet.ssl.trustRootFromCertificates returns an object
suitable for use as trustRoot= to
twisted.internet.ssl.optionsForClientTLS that trusts multiple
certificates. (#7671)
- twisted.python.roots is now ported to Python 3. (#8131)
- twisted.cred.strports has been ported to Python 3. (#8216)
Bugfixes
--------
- Expected failures from standard library unittest no longer fail
with Trial reporters. (#4811)
- twisted.internet.endpoints.HostnameEndpoint.connect no longer fails
with an AlreadyCalledError when the Deferred it returns is
cancelled after all outgoing connection attempts have been made but

advertises protocols over both NPN and ALPN. Also added new
INegotiated interface for TLS interfaces that support protocol
negotiation. This interface adds a negotiatedProtocol property that
reports what protocol, if any, was negotiated in the TLS handshake.

called, such as when work is scheduled in the reactor via
reactor.callInThread() before reactor.run(). (#8090)
Improved Documentation
----------------------

On behalf of Twisted Matrix Laboratories, Iâm releasing Twisted
14.0.1, a security release for Twisted 14.0. It is strongly suggested
that users of 14.0.0 upgrade to this release.
This patches a bug in Twisted Webâs Agent, where BrowserLikePolicyForHTTPS
would not honour the trust root given, and would use the system
trust root instead. This would have broken, for example, attempting
to pin the issuer for your HTTPS application because you only trust
one issuer.
Note: on OS X, with the system OpenSSL, you still can't fully rely
on this API for issuer pinning, due to modifications by Apple â
please see https://hynek.me/articles/apple-openssl-verification-surprises/
for more details.
Some parts are ported to python-3, but most parts not, so leave
it disabled for now.
Twisted Core 14.0.0 (2014-05-08)
================================
Features
--------
- twisted.internet.interfaces.IUDPTransport - and that interface's
implementations in Twisted - now supports enabling broadcasting.
(#454)
- trial's TestCase will now report a test method as an error if that
test method is a generator function, preventing an issue when a
user forgets to decorate a test method with defer.inlineCallbacks,
causing the test method to not run. (#3917)
- twisted.positioning, a new API for positioning systems such as GPS,
has been added. It comes with an implementation of NMEA, the most
common wire protocol for GPS devices. It will supersede
twisted.protoocols.gps. (#3926)
- The new interface twisted.internet.interfaces.IStreamClientEndpoint
StringParserWithReactor will supply the reactor to its
parseStreamClient method, passed along from
twisted.internet.endpoints.clientFromString. (#5069)
- IReactorUDP.listenUDP, IUDPTransport.write and
IUDPTransport.connect now accept ipv6 address literals. (#5086)
- A new API, twisted.internet.ssl.optionsForClientTLS, allows clients
to specify and verify the identity of the peer they're communicating
with. When used with the service_identity library from PyPI, this
provides support for service identity verification from RFC 6125, as
well as server name indication from RFC 6066. (#5190)
- Twisted's TLS support now provides a way to ask for user-configured
trust roots rather than having to manually configure such
certificate authority certificates yourself.
twisted.internet.ssl.CertificateOptions now accepts a new argument,
trustRoot, which combines verification flags and trust sources, as
well as a new function that provides a value for that argument,
twisted.internet.ssl.platformTrust, which allows using the trusted
platform certificate authorities from OpenSSL for certificate
verification. (#5446)
- Constants are now comparable/orderable based on the order in which
they are defined. (#6523)
- "setup.py install" and "pip install" now work on Python 3.3,
installing the subset of Twisted that has been ported to Python 3.
(#6539)
- twisted.internet.ssl.CertificateOptions now supports ECDHE for
servers by default on pyOpenSSL 0.14 and later, if the underlying
versions of cryptography.io and OpenSSL support it. (#6586)
- twisted.internet.ssl.CertificateOptions now allows the user to set
acceptable ciphers and uses secure ones by default. (#6663)
- The Deferred returned by
twisted.internet.defer.DeferredFilesystemLock.deferUntilLocked can
now be cancelled. (#6720)
- twisted.internet.ssl.CertificateOptions now enables TLSv1.1 and
TLSv1.2 by default (in addition to TLSv1.0) if the underlying
version of OpenSSL supports these protocol versions. (#6772)
- twisted.internet.ssl.CertificateOptions now supports Diffie-Hellman
key exchange. (#6799)
- twisted.internet.ssl.CertificateOptions now disables TLS
compression to avoid CRIME attacks and, for servers, uses server
preference to choose the cipher. (#6801)
- SSL server endpoint string descriptions now support the
specification of Diffie-Hellman key exchange parameter files.
(#6924)
- twisted.python.reflect.requireModule was added to handle
conditional imports of python modules and work around pyflakes
warnings of unused imports code. (#7014)
Bugfixes
--------
- If a ProcessProtocol.processExited method raised an exception a
broken process handler would be left in the global process state
leading to errors later on. This has been fixed and now an error
will be logged instead. (#5151)
- Twisted now builds on Solaris. Note that lacking a Buildbot slave
(see http://buildbot.twistedmatrix.com/boxes-supported) Solaris is
not a supported Twisted platform. (#5728)
- twisted.internet.utils is now correctly installed on Python 3.
(#6929)
- twisted.python.threadpool.ThreadPool no longer starts new workers
when its pool size is changed while the pool is not running.
(#7011)
Improved Documentation
----------------------
- Twisted now uses the Sphinx documentation generator for its
narrative documentation, which means that the source format for
narrative documentation has been converted to ReStructuredText.
(#4500)
- The Sphinx documentation is now also configured to allow
intersphinx links to standard library documentation. (#4582)
- The docstring for twisted.internet.task.react now better documents
the main parameter (#6071)
- The writing standard now explicitly mandates the usage of
ungendered pronouns. (#6858)
Deprecations and Removals
-------------------------
- test_import.py was removed as it was redundant. (#2053)
- Support for versions of pyOpenSSL older than 0.10 has been removed.
Affected users should upgrade pyOpenSSL. (#5014)
- twisted.internet.interfaces.IStreamClientEndpointStringParser is
now deprecated in favor of twisted.internet.interfaces.IStreamClien
tEndpointStringParserWithReactor. (#5069)
- unsignedID and setIDFunction, previously part of
twisted.python.util and deprecated since 13.0, have now been
removed. (#6707)
- FTPClient.changeDirectory was deprecated in 8.2 and is now removed.
(#6759)
- twisted.internet.stdio.StandardIO.closeStdin, an alias for
loseWriteConnection only available on POSIX and deprecated since
2.1, has been removed. (#6785)
- twisted.python.reflect.getcurrent is now deprecated and must not be
used. twisted.python.reflect.isinst is now deprecated in favor of
the built-in isinstance. (#6859)

Twisted Names 14.0.0 (2014-05-08)
=================================
Features
--------
- twisted.names.root.Resolver now accepts a resolverFactory argument,
which makes it possible to control how root.Resolver performs
iterative queries to authoritative nameservers. (#6095)
- twisted.names.dns.Message now has a repr method which shows only
those instance flags, fields and sections which are set to non-
default values. (#6847)
- twisted.names.dns.Message now support rich comparison. (#6848)
Bugfixes
--------
- twisted.names.server.DNSServerFactory now responds with messages
whose flags and fields are reset to their default values instead of
copying these from the request. This means that AD and CD flags,
and EDNS OPT records in the request are no longer mirrored back to
the client. (#6645)
Improved Documentation
----------------------
- twisted.names now has narrative documentation showing how to create
a custom DNS server. (#6864)
- twisted.names.server now has full API documentation. (#6886)
- twisted.names now has narrative documentation explaining how to use
its client APIs. (#6925)
- twisted.names now has narrative documentation and examples showing
how to perform reverse DNS lookups. (#6969)

Twisted Pair 14.0.0 (2014-05-08)
================================
Features
--------
- twisted.pair.tuntap now has complete test coverage, basic
documentation, and works without the difficult-to-find system
bindings it used to require. (#6169)

Twisted Web 14.0.0 (2014-05-08)
===============================
Features
--------
- twisted.web.http.proxiedLogFormatter can now be used with
twisted.web.http.HTTPFactory (and subclasses) to record X
-Forwarded-For values to the access log when the HTTP server is
deployed behind a reverse proxy. (#1468)
- twisted.web.client.Agent now uses
twisted.internet.ssl.CertificateOptions for SSL/TLS and benefits
from its continuous improvements. (#6893)
Bugfixes
--------
- twisted.web.client.Agent now correctly manage flow-control on
pooled connections, and therefore requests will no longer hang
sometimes when deliverBody is not called synchronously within the
callback on Request. (#6751)
- twisted.web.client.Agent now verifies that the provided server
certificate in a TLS connection is trusted by the platform. (#7042)
- When requesting an HTTPS URL with twisted.web.client.Agent, the
hostname of the presented certificate will be checked against the
requested hostname; mismatches will now result in an error rather
than a man-in-the-middle opportunity for attackers. This may break
existing code that incorrectly depended on insecure behavior, but
such code was erroneous and should be updated. (#4888)

either because they themselves are not ready or because a
dependency isn't. This is annotated by
PYTHON_VERSIONS_INCOMPATIBLE= 33 # not yet ported as of x.y.z
or
PYTHON_VERSIONS_INCOMPATIBLE= 33 # py-foo, py-bar
respectively, please use the same style for other packages,
and check during updates.
Use versioned_dependencies.mk where applicable.
Use REPLACE_PYTHON instead of handcoded alternatives, where applicable.
Reorder Makefile sections into standard order, where applicable.
Remove PYTHON_VERSIONS_INCLUDE_3X lines since that will be default
with the next commit.
Whitespace cleanups and other nits corrected, where necessary.
* Twisted now includes a HostnameEndpoint implementation which uses IPv4 and IPv6 in parallel, speeding up the connection by using whichever connects first (the 'Happy Eyeballs'/RFC 6555 algorithm).
* Improved support for Cancellable Deferreds by kaizhang, our GSoC student.
* Improved Twisted.Mail documentation by shira, our Outreach Program for Women intern.
* twistd now waits for the application to start successfully before exiting after daemonization.
* SSL server endpoint string descriptions now support the specification of chain certificates.
* Over 70 closed tickets since 13.1.0.
- trial now has an --exitfirst flag which stops the test run after
the first error or failure.
- twisted.internet.ssl.CertificateOptions now supports chain
certificates.
- twisted.internet.endpoints now provides ProcessEndpoint, a child
process endpoint.
- Factory now has a forProtocol classmethod that constructs an
instance and sets its protocol attribute.
- twisted.internet.endpoints.connectProtocol allows connecting to a
client endpoint using only a protocol instance, rather than
requiring a factory.
- twisted.trial.unittest.SynchronousTestCase.assertNoResult no longer
swallows the result, if the assertion succeeds.
- twisted.python.constants.FlagConstant implements __iter__ so that
it can be iterated upon to find the flags that went into a flag
set, and implements __nonzero__ to test as false when empty.
- assertIs and assertIsNot have now been added to
twisted.trial.unittest.TestCase.
- twisted.trial.unittest.TestCase.failureResultOf now takes an
optional expected failure type argument.
- The POSIX implementation of
twisted.internet.interfaces.IReactorProcess now does not change the
parent process UID or GID in order to run child processes with a
different UID or GID.
