===========================
Bugfixes
--------
- spawnProcess no longer opens an unwanted console on Windows (5726)
- 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 (see 9126). (8069)
- twisted.logger now buffers only 200 events by default (reduced from 65536)
while waiting for observers to be configured. (8164)
- 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. (8184)
- twisted.protocols.finger now works on Python 3. (8230)
- 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. (8898)
- 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.
(8912)
- 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. (9032)
- 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. (9047)
- twisted.internet._threadedselect now works on both Python 2 and 3. (9053)
- 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Python's standard library (which has an out of date idna module) from mis-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. (9137)
Improved Documentation
----------------------
- The examples in Twisted howto "Using the Twisted Application Framework",
section "Customizing twistd logging" have been updated to use latest logging
modules and syntax (9084)
Features
--------
- twisted.internet.defer.Deferred.asFuture and
twisted.internet.defer.Deferred.fromFuture were added, allowing for easy
transitions between asyncio coroutines (which await Futures) and twisted
coroutines (which await Deferreds). (8748)
- twisted.application.internet.ClientService.whenConnected now accepts an
argument "failAfterFailures". If you set this to 1, the Deferred returned by
whenConnected will errback when the connection attempt fails, rather than
retrying forever. This lets you react (probably by stopping the
ClientService) to connection errors that are likely to be persistent, such as
using the wrong hostname, or not being connected to the internet at all.
(9116)
- twisted.protocols.tls.TLSMemoryBIOProtocol and anything that uses it
indirectly including the TLS client and server endpoints now enables TLS 1.3
cipher suites. (9128)

Deprecations and Removals
-------------------------
- twisted.runner.inetdconf.InvalidRPCServicesConfError,
twisted.runner.inetdconf.RPCServicesConf, twisted.runner.inetdtap.RPCServer,
and twisted.runner.portmap, deprecated since 16.2.0, have been removed.
(8464)
- twisted.python.url and twisted.python._url were modified to rely on
hyperlink, a new package based on the Twisted URL implementation. Hyperlink
adds support for IPv6 (fixing 8069), correct username/password encoding,
better scheme/netloc inference, improved URL.click() behavior (fixing 8184),
and more. For full docs see hyperlink.readthedocs.io and the CHANGELOG in the
hyperlink GitHub repo. (9126)
Conch
-----
Bugfixes
~~~~~~~~
- History-aware terminal protocols like twisted.conch.manhole.Manhole no longer
raise a TypeError when a user visits a partial line they added to the command
line history by pressing up arrow before return. (9031)
- The telnet_echo.tac example had conflicting port callouts between runtime and
documentation. File was altered to run on documented port, 6023. (9055)
Deprecations and Removals
~~~~~~~~~~~~~~~~~~~~~~~~~
- Remove diffie-hellman-group1-sha1 from twisted.conch. See https://weakdh.org/
(9019)
- Removed small and obscure elliptic curves from conch. The only curves conch
supports now are the ones also supported by OpenSSH. (9088)
Mail
----
Bugfixes
~~~~~~~~
- twisted.mail.smtp has been ported to Python 3. (8770)
Names
-----
Bugfixes
~~~~~~~~
- RRHeader now converts its ttl argument to an integer, raising a TypeError if
it cannot. (8340)
Web
---
Bugfixes
~~~~~~~~
- twisted.web.cgi now works on Python 3 (8009)
- twisted.web.distrib now works on Python 3 (8010)
- twisted.web.http.HTTPFactory now propagates its reactor's callLater method to
the HTTPChannel object, rather than having callLater grab the global reactor.
This prevents the possibility of HTTPFactory logging using one reactor, but
HTTPChannel running timeouts on another. (8904)
Improved Documentation
~~~~~~~~~~~~~~~~~~~~~~
- twisted.web.template.flattenString docstring now correctly references
io.BytesIO (rather than NativeStringIO). (9028)
Features
~~~~~~~~
- twisted.web.client now exposes the RequestGenerationFailed exception type.
(5310)
- twisted.web.client.Agent will now parse responses that begin with a status
line that is missing a phrase. (7673)
- twisted.web.http.HTTPChannel and twisted.web._http2.H2Connection have been
enhanced so that after they time out they wait a small amount of time to
allow the connection to close gracefully and, if it does not, they forcibly
close it to avoid allowing malicious clients to forcibly keep the connection
open. (8902)

Words
-----
Deprecations and Removals
~~~~~~~~~~~~~~~~~~~~~~~~~
- twisted.words.protocols.oscar, which is client code for Oscar/ICQ, was
deprecated in 16.2.0 and has now been removed. (9024)
Twisted Core 17.1.0 (2017-02-04)
================================
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. (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.
(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. (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. (8247)
- trial --help-reactors will only list reactors which can be
imported. (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.
(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. (8941)
- twisted.trial._dist.test.test_distreporter now works on Python 3.
(8943)
Bugfixes
--------
- trial --help-reactors will now display iocp and win32er reactors
with Python 3. (8745)
- twisted.logger._flatten.flattenEvent now handles log_format being
None instead of assuming the value is always a string. (8860)
- twisted.protocol.ftp is now Python 3 compatible (8865)
- twisted.names.client.Resolver can now resolve names with IPv6 DNS
servers. (8877)
- twisted.application.internet.ClientService now waits for existing
connections to disconnect before trying to connect again when
restarting. (8899)
- twisted.internet.unix.Server.doRead and
twisted.internet.unix.Client.doRead no longer fail if recvmsg's
ancillary data contains more than one file descriptor. (8911)
- twist on Python 3 now correctly prints the help text when given no
plugin to run. (8918)
- twisted.python.sendmsg.sendmsg no longer segfaults on Linux +
Python 2. (8969)
- IHandshakeListener providers connected via SSL4ClientEndpoint will
now have their handshakeCompleted methods called. (8973)
- The twist script now respects the --reactor option. (8983)
- Fix crash when using SynchronousTestCase with Warning object which
does not store a string as its first argument (like
libmysqlclient). (9005)
- twisted.python.compat.execfile() does not open files with the
deprecated 'U' flag on Python 3. (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.
(6800)
- twisted.protocols.telnet (not to be confused with the supported
twisted.conch.telnet), deprecated since Twisted 2.5, has been
removed. (8925)
- twisted.application.strports.parse, as well as the deprecated
default arguments in strports.service/listen, deprecated since
Twisted 10.2, has been removed. (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. (8960)
- twisted.internet.defer.timeout is deprecated in favor of
twisted.internet.defer.Deferred.addTimeout (8971)

- Twisted Conch now supports ECDH key exchanges. (8730)
- Add support in twisted.conch.ssh for hmac-sha2-384 (8784)
- conch and cftp scripts now work on Python 3. (8791)
- twisted.conch.ssh supports ECDH key exchange. (8811)
Bugfixes
--------
- twisted.conch.ssh.keys.Key.fromString now supports OpenSSL private
keys with Windows line endings (\r\n) again (broken since 16.6.0).
(8928)
Improved Documentation
----------------------
- The documentation for
twisted.conch.endpoints.SSHCommandClientEndpoint.existingConnection
now describes where the value for the connection parameter might
come from. (8892)

Twisted Mail 17.1.0 (2017-02-04)
================================
Deprecations and Removals
-------------------------
- twisted.mail.tap (the twist plugin for mail) no longer accepts the
--pop3s option or implicit port numbers to --pop3 and --smtp. This
functionality has been deprecated since 11.0. (8920)
Twisted Names 17.1.0 (2017-02-04)
=================================
Bugfixes

Bugfixes
--------
- On Python 3, procmon now handles process output without exceptions
(8919)
Twisted Web 17.1.0 (2017-02-04)
===============================
Features
--------
- twisted.web.client.Agent now sets ``Content-Length: 0`` for PUT and
POST requests made without a body producer. (8984)
Bugfixes
--------
- twisted.web.http.HTTPFactory now times connections out after one
minute of no data from the client being received, before the
request is complete, rather than twelve hours. (3746)
- twisted.web.http.HTTPChannel, the server class for Twisted's
HTTP/1.1 server, now exerts backpressure against clients that do
not read responses. This means that if a client stops reading from
a socket for long enough, Twisted will stop reading further
requests from that client until it consumes some responses. (8868)
- twisted.web.http_headers.Headers.getRawHeaders no longer attempts
to decode the default value when called with a unicode header name.
(8974)
- twisted.web.http.HTTPChannel is less likely to leak file
descriptors when timing out clients using HTTPS connections. In
some cases it is still possible to leak a file descriptor when
timing out HTTP clients: further patches will address this issue.

- The twist script can now be run by invoking python -m twisted.
(8657)
- twisted.protocols.sip has been ported to Python 3. (8669)
- 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)

--------
- twisted.conch.ssh.keys supports ECDSA keys (8798)
- scripts/ckeygen can now generate ecdsa keys. (8828)
- 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)

===============================
Features
--------
- twisted.web.server.Site's HTTP/2 server support now emits vastly
fewer WINDOW_UPDATE frames than previously. (8681)
Bugfixes
--------
- twisted.web.Agent now tolerates receiving unexpected status codes
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)
================================
Features
--------
- Added twisted.internet.defer.Deferred.addTimeout method to enable
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 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)

==================================
Features
--------
- twisted.runner has been ported to Python 3. (8739)
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)

- twisted.words.protocols.jabber is now ported to Python 3 (8423)
- twisted.words.protocols.irc.ERR_TOOMANYMATCHES was introduced
according to the RFC 2812 errata. (8585)
Bugfixes
--------
- twisted.words.protocols.irc.RPL_ADMINLOC was removed and replaced
with twisted.words.protocols.irc.RPL_ADMINLOC1 and
twisted.words.protocols.irc.RPL_ADMINLOC2 to match the admin
commands defined in RFC 2812. (8585)
- twisted.words.protocols.jabber.sasl_mechanisms has been fixed for
Python 3.3 (8738)

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)

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 Words 16.3.0 (2016-07-05)
=================================
No significant changes have been made for this release.
Twisted Core 16.2.0 (2016-05-18)
================================
Features
--------
- twisted.protocols.haproxy.proxyEndpoint provides an endpoint that
wraps any other stream server endpoint with the PROXY protocol that
retains information about the original client connection handled by
the proxy; this wrapper is also exposed via the string description
prefix 'haproxy'; for example 'twistd web --port haproxy:tcp:8765'.
(8203)
- twisted.application.app.AppLogger (used by twistd) now uses the new
logging system. (8235)
Bugfixes
--------
- twisted.application-using applications (trial, twistd, etc) now
work with the --reactor option on Python 3. (8299)
- Failures are now logged by STDLibLogObserver. (8316)
Improved Documentation
----------------------
- Deprecation documentation was extended to include a quick check
list for developers. (5645)
- The Twisted Deprecation Policy is now documented in the Twisted
Development Policy. (8082)
- The documentation examples for UDP now work on Python 3. (8280)
Deprecations and Removals
-------------------------
- Passing a factory that produces log observers that do not implement
twisted.logger.ILogObserver or twisted.python.log.ILogObserver to
twisted.application.app.AppLogger has been deprecated. This is
primarily used by twistd's --logger option. Please use factories
that produce log observers implementing twisted.logger.ILogObserver
or the legacy twisted.python.log.ILogObserver. (8235)
- twisted.internet.qtreactor, a stub that imported the external
qtreactor, has been removed. (8288)

log messages from being created. (8272)
- twisted.web.http.HTTPChannel no longer processes requests that have
invalid headers as the final header in their header block. (8317)

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)

with an AlreadyCalledError when the Deferred it returns is
cancelled after all outgoing connection attempts have been made but
none have yet succeeded or failed. (8014)
- twisted.internet.task.LoopingCall.withCount when run with internal
of 0, now calls the countCallable with 1, regardless of the time
passed between calls. (8125)

strports definition, now gives the correct error message when an
empty chain file is given. (8222)
Improved Documentation
----------------------
- The Twisted Project has adopted the Contributor Covenant as its
Code of Conduct. (8173)

negotiation. This interface adds a negotiatedProtocol property that
reports what protocol, if any, was negotiated in the TLS handshake.
(7860)

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 documentation
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)
