What's new in Tornado 4.4
=========================
Jul 15, 2016
------------
General
~~~~~~~
* Tornado now requires Python 2.7 or 3.3+; versions 2.6 and 3.2 are no
longer supported. Pypy3 is still supported even though its latest
release is mainly based on Python 3.2.
* The `monotonic <https://pypi.python.org/pypi/monotonic>`_ package is
now supported as an alternative to `Monotime
<https://pypi.python.org/pypi/Monotime>`_ for monotonic clock support
on Python 2.
``tornado.curl_httpclient``
~~~~~~~~~~~~~~~~~~~~~~~~~~~
* Failures in ``_curl_setup_request`` no longer cause the
``max_clients`` pool to be exhausted.
* Non-ascii header values are now handled correctly.
`tornado.gen`
~~~~~~~~~~~~~
* `.with_timeout` now accepts any yieldable object (except
``YieldPoint``), not just `tornado.concurrent.Future`.
`tornado.httpclient`
~~~~~~~~~~~~~~~~~~~~
* The errors raised by timeouts now indicate what state the request
was in; the error message is no longer simply "599 Timeout".
* Calling `repr` on a `tornado.httpclient.HTTPError` no longer raises
an error.
`tornado.httpserver`
~~~~~~~~~~~~~~~~~~~~
* Int-like enums (including `http.HTTPStatus`) can now be used as
status codes.
* Responses with status code ``204 No Content`` no longer emit a
``Content-Length: 0`` header.
`tornado.ioloop`
~~~~~~~~~~~~~~~~
* Improved performance when there are large numbers of active timeouts.
`tornado.netutil`
~~~~~~~~~~~~~~~~~
* All included `.Resolver` implementations raise `IOError` (or a
subclass) for any resolution failure.
`tornado.options`
~~~~~~~~~~~~~~~~~
* Options can now be modified with subscript syntax in addition to
attribute syntax.
* The special variable ``__file__`` is now available inside config files.
``tornado.simple_httpclient``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* HTTP/1.0 (not 1.1) responses without a ``Content-Length`` header now
work correctly.
`tornado.tcpserver`
~~~~~~~~~~~~~~~~~~~
* `.TCPServer.bind` now accepts a ``reuse_port`` argument.
`tornado.testing`
~~~~~~~~~~~~~~~~~
* Test sockets now always use ``127.0.0.1`` instead of ``localhost``.
This avoids conflicts when the automatically-assigned port is
available on IPv4 but not IPv6, or in unusual network configurations
when ``localhost`` has multiple IP addresses.
`tornado.web`
~~~~~~~~~~~~~
* ``image/svg+xml`` is now on the list of compressible mime types.
* Fixed an error on Python 3 when compression is used with multiple
``Vary`` headers.
`tornado.websocket`
~~~~~~~~~~~~~~~~~~~
* ``WebSocketHandler.__init__`` now uses `super`, which improves
support for multiple inheritance.
