`.IOStream` and ``simple_httpclient``, but not ``curl_httpclient``.
* The default SSL configuration has become stricter, using
`ssl.create_default_context` where available.
+* The deprecated classes in the `tornado.auth` module, ``GoogleMixin``,
+ ``FacebookMixin``, and ``FriendFeedMixin`` have been removed.
+`tornado.autoreload`
+~~~~~~~~~~~~~~~~~~~~
+
+* Improved compatibility with Windows.
`tornado.gen`
~~~~~~~~~~~~~
* On Python 3, catching an exception in a coroutine no longer leads to
leaks via ``Exception.__context__``.
+`tornado.httpclient`
+~~~~~~~~~~~~~~~~~~~~
+
+* The ``raise_error`` argument now works correctly with the synchronous
+ `.HTTPClient`.
+
+`tornado.httpserver`
+~~~~~~~~~~~~~~~~~~~~
+
+* `.HTTPServer` is now a subclass of `tornado.util.Configurable`.
+
`tornado.ioloop`
~~~~~~~~~~~~~~~~
* ``SSLIOStream.connect`` and `.IOStream.start_tls` now validate certificates
by default.
+* New method `.SSLIOStream.wait_for_handshake` allows server-side applications
+ to wait for the handshake to complete in order to verify client certificates
+ or use NPN/ALPN.
+* The `.Future` returned by ``SSLIOStream.connect`` now resolves after the
+ handshake is complete instead of as soon as the TCP connection is
+ established.
+* Reduced logging of SSL errors.
+* `.BaseIOStream.read_until_close` now works correctly when a
+ ``streaming_callback`` is given but ``callback`` is None (i.e. when
+ it returns a `.Future`)
+
+`tornado.locale`
+~~~~~~~~~~~~~~~~
+
+* New method `.GettextLocale.pgettext` allows additional context to be
+ supplied for gettext translations.
+
+`tornado.locks`
+~~~~~~~~~~~~~~~
+
+* New module contains locking and synchronization functionality imported
+ from `Toro <http://toro.readthedocs.org>`_.
`tornado.log`
~~~~~~~~~~~~~
* `.define_logging_options` now works correctly when given a non-default
``options`` object.
+`tornado.process`
+~~~~~~~~~~~~~~~~~
+
+* New method `.Subprocess.wait_for_exit` is a coroutine-friendly
+ version of `.Subprocess.set_exit_callback`.
+
``tornado.simple_httpclient``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* Improved performance on Python 3 by reusing a single `ssl.SSLContext`.
+`tornado.queues`
+~~~~~~~~~~~~~~~~
+
+* New module contains queues imported from `Toro
+ <http://toro.readthedocs.org>`_.
+
+`tornado.tcpserver`
+~~~~~~~~~~~~~~~~~~~
+
+* `.TCPServer.handle_stream` may be a coroutine (so that any exceptions
+ it raises will be logged).
+
`tornado.util`
~~~~~~~~~~~~~~
* `.import_object` now supports unicode strings on Python 2.
+* `.Configurable.initialize` now supports positional arguments.
`tornado.web`
~~~~~~~~~~~~~
* Passing ``secure=False`` or ``httponly=False`` to
`.RequestHandler.set_cookie` now works as expected (previously only the
presence of the argument was considered and its value was ignored).
+* Parsing of the ``If-None-Match`` header now follows the RFC and supports
+ weak validators.
+* `.RequestHandler.get_arguments` now requires that its ``strip`` argument
+ be of type bool. This helps prevent errors caused by the slightly dissimilar
+ interfaces between the singular and plural methods.
+* Errors raised in ``_handle_request_exception`` are now logged more reliably.
+* `.RequestHandler.redirect` now works correctly when called from a handler
+ whose path begins with two slashes.
+* Passing messages containing ``%`` characters to `tornado.web.HTTPError`
+ no longer causes broken error messages.
`tornado.websocket`
