v1.1.0

v1.1.0: We are pleased to announce the release of Tornado 1.1, available from

Changes in this release:
* RequestHandler.async_callback and related functions in other classes
  are no longer needed in most cases (although it's harmless to continue
  using them).  Uncaught exceptions will now cause the request to be closed
  even in a callback.  If you're curious how this works, see the new
  tornado.stack_context module.
* The new tornado.testing module contains support for unit testing
  asynchronous IOLoop-based code.
* AsyncHTTPClient has been rewritten (the new implementation was available as
  AsyncHTTPClient2 in Tornado 1.0; both names are supported for backwards
  compatibility).
* The tornado.auth module has had a number of updates, including support
  for OAuth 2.0 and the Facebook Graph API, and upgrading Twitter and
  Google support to OAuth 1.0a.
* The websocket module is back and supports the latest version (76) of the
  websocket protocol.  Note that this module's interface is different
  from the websocket module that appeared in pre-1.0 versions of Tornado.
* New method RequestHandler.initialize() can be overridden in subclasses
  to simplify handling arguments from URLSpecs.  The sequence of methods
  called during initialization is documented at
  http://tornadoweb.org/documentation#overriding-requesthandler-methods
* get_argument() and related methods now work on PUT requests in addition
  to POST.
* The httpclient module now supports HTTP proxies.
* When HTTPServer is run in SSL mode, the SSL handshake is now non-blocking.
* Many smaller bug fixes and documentation updates

Backwards-compatibility notes:
* While most users of Tornado should not have to deal with the stack_context
  module directly, users of worker thread pools and similar constructs may
  need to use stack_context.wrap and/or NullContext to avoid memory leaks.
* The new AsyncHTTPClient still works with libcurl version 7.16.x, but it
  performs better when both libcurl and pycurl are at least version 7.18.2.
* OAuth transactions started under previous versions of the auth module
  cannot be completed under the new module.  This applies only to the
  initial authorization process; once an authorized token is issued that
  token works with either version.

Many thanks to everyone who contributed patches, bug reports, and feedback
that went into this release!
