For those unfamiliar with the "open source version of the scalable, non-blocking web server and tools that power FriendFeed," Tornado is different from typical Python frameworks in that it is non-blocking, allowing it to process thousands of standing connections simultaneously, and making it ideal for real-time web services.  While Tornado 2.0 provided some improvements, it also created some issues with backwards compatability:

Tornado 2.0 introduces several potentially backwards-incompatible changes, including in particular automatic escaping of template output.

So it should be no surprise that the big news for this release is the improved compatability between Twisted and Tornado. Other improvements of note are:

  • Updated and expanded WebSocket support
  • Template errors now generate better stack traces
  • Better exception handling in tornado.gen
  • tornado.simple_httpclient disables SSLv2

Tornado requires Python 2.5, 2.6, 2.7, or 3.2, and is designed to run on most Unix-like platforms, though Linux and BSD (including Mac OS X) are preferred.
