~~~~~~~~~~~~~~~~~~~~
* Improved compatibility with Windows.
+* Fixed a bug in Python 3 if a module was imported during a reload check.
+
+`tornado.concurrent`
+~~~~~~~~~~~~~~~~~~~~
+
+* `.run_on_executor` now accepts arguments to control which attributes
+ it uses to find the `.IOLoop` and executor.
+
+``tornado.curl_httpclient``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+* Fixed a bug that would cause the client to stop processing requests
+ if an exception occurred in certain places while there is a queue.
`tornado.gen`
~~~~~~~~~~~~~
* On Python 3, catching an exception in a coroutine no longer leads to
leaks via ``Exception.__context__``.
+* `tornado.gen.Multi` and `tornado.gen.multi_future` (which are used when
+ yielding a list or dict in a coroutine) now log any exceptions after the
+ first if more than one `.Future` fails (previously they would be logged
+ when the `.Future` was garbage-collected, but this is more reliable).
+ Both have a new keyword argument ``quiet_exceptions`` to suppress
+ logging of certain exception types; to use this argument you must
+ call ``Multi`` or ``multi_future`` directly instead of simply yielding
+ a list.
+* `.multi_future` now works when given multiple copies of the same `.Future`.
+* `.WaitIterator` now works even if no hard reference to the iterator itself
+ is kept.
`tornado.httpclient`
~~~~~~~~~~~~~~~~~~~~
* `.PeriodicCallback` is now more efficient when the clock jumps forward
by a large amount.
+* The `.IOLoop` constructor now has a ``make_current`` keyword argument
+ to control whether the new `.IOLoop` becomes `.IOLoop.current()`.
+* Third-party implementations of `.IOLoop` should accept ``**kwargs``
+ in their `~.IOLoop.initialize` methods and pass them to the superclass
+ implementation.
`tornado.iostream`
~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* Improved performance on Python 3 by reusing a single `ssl.SSLContext`.
+* New constructor argument ``max_body_size`` controls the maximum response
+ size the client is willing to accept. It may be bigger than
+ ``max_buffer_size`` if ``streaming_callback`` is used.
`tornado.tcpserver`
~~~~~~~~~~~~~~~~~~~
It is not normally necessary to call `multi_future` explcitly,
since the engine will do so automatically when the generator
- yields a list of `Futures`. However, calling it directly
+ yields a list of ``Futures``. However, calling it directly
allows you to use the ``quiet_exceptions`` argument to control
the logging of multiple exceptions.
