| What's new in Tornado 1.1 |
| ========================= |

| We are pleased to announce the release of Tornado 1.1, available from |
| http://github.com/downloads/facebook/tornado/tornado-1.1.tar.gz |
| |
| 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! |
