| What's new in Tornado 1.0 |
| ========================= |

| |
| We are pleased to announce the release of Tornado 1.0, available |
| from |
| http://github.com/downloads/facebook/tornado/tornado-1.0.tar.gz. |
| There have been many changes since version 0.2; here are some of |
| the highlights: |
| |
| New features: |
| * Improved support for running other WSGI applications in a |
| Tornado server (tested with Django and CherryPy) |
| * Improved performance on Mac OS X and BSD (kqueue-based IOLoop), |
| and experimental support for win32 |
| * Rewritten AsyncHTTPClient available as |
| tornado.httpclient.AsyncHTTPClient2 (this will become the |
| default in a future release) |
| * Support for standard .mo files in addition to .csv in the locale |
| module |
| * Pre-forking support for running multiple Tornado processes at |
| once (see HTTPServer.start()) |
| * SSL and gzip support in HTTPServer |
| * reverse_url() function refers to urls from the Application |
| config by name from templates and RequestHandlers |
| * RequestHandler.on_connection_close() callback is called when the |
| client has closed the connection (subject to limitations of the |
| underlying network stack, any proxies, etc) |
| * Static files can now be served somewhere other than /static/ via |
| the static_url_prefix application setting |
| * URL regexes can now use named groups ("(?P<name>)") to pass |
| arguments to get()/post() via keyword instead of position |
| * HTTP header dictionary-like objects now support multiple values |
| for the same header via the get_all() and add() methods. |
| * Several new options in the httpclient module, including |
| prepare_curl_callback and header_callback |
| * Improved logging configuration in tornado.options. |
| * UIModule.html_body() can be used to return html to be inserted |
| at the end of the document body. |
| |
| Backwards-incompatible changes: |
| * RequestHandler.get_error_html() now receives the exception |
| object as a keyword argument if the error was caused by an |
| uncaught exception. |
| * Secure cookies are now more secure, but incompatible with |
| cookies set by Tornado 0.2. To read cookies set by older |
| versions of Tornado, pass include_name=False to |
| RequestHandler.get_secure_cookie() |
| * Parameters passed to RequestHandler.get/post() by extraction |
| from the path now have %-escapes decoded, for consistency with |
| the processing that was already done with other query |
| parameters. |
| |
| Many thanks to everyone who contributed patches, bug reports, and |
| feedback that went into this release! |
