What's new in Tornado 2.1.1
===========================
Oct 4, 2011
-----------
Bug fixes
~~~~~~~~~
* Fixed handling of closed connections with the ``epoll`` (i.e. Linux)
``IOLoop``. Previously, closed connections could be shut down too early,
which most often manifested as "Stream is closed" exceptions in
``SimpleAsyncHTTPClient``.
* Fixed a case in which chunked responses could be closed prematurely,
leading to truncated output.
* ``IOStream.connect`` now reports errors more consistently via logging
and the close callback (this affects e.g. connections to localhost
on FreeBSD).
* ``IOStream.read_bytes`` again accepts both ``int`` and ``long`` arguments.
* ``PeriodicCallback`` no longer runs repeatedly when ``IOLoop`` iterations
complete faster than the resolution of ``time.time()`` (mainly a problem
on Windows).
Backwards-compatibility note
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* Listening for ``IOLoop.ERROR`` alone is no longer sufficient for detecting
closed connections on an otherwise unused socket. ``IOLoop.ERROR`` must
always be used in combination with ``READ`` or ``WRITE``.
