We are pleased to announce the release of Tornado 2.0, available from 

Major changes:
* Template output is automatically escaped by default; see backwards
  compatibility note below.
* The default AsyncHTTPClient implementation is now simple_httpclient.
* Python 3.2 is now supported.

Backwards compatibility:
* Template autoescaping is enabled by default.  Applications upgrading from
  a previous release of Tornado must either disable autoescaping or adapt
  their templates to work with it.  For most applications, the simplest
  way to do this is to pass autoescape=None to the Application constructor.
* Applications that wish to continue using curl_httpclient instead of
  simple_httpclient may do so by calling
    AsyncHTTPClient.configure("tornado.curl_httpclient.CurlAsyncHTTPClient")
  at the beginning of the process.  Users of Python 2.5 will probably want
  to use curl_httpclient as simple_httpclient only supports ssl on Python 2.6+.
* Python 3 compatibility involved many changes throughout the codebase,
  so users are encouraged to test their applications more thoroughly than
  usual when upgrading to this release.

Other changes in this release:
* Templates support several new directives:
  - {% autoescape ...%} to control escaping behavior
  - {% raw ... %} for unescaped output
  - {% module ... %} for calling UIModules
* {% module Template(path, **kwargs) %} may now be used to call another
  template with an independent namespace
* All IOStream callbacks are now run directly on the IOLoop via add_callback.
* HTTPServer now supports IPv6 where available.  To disable, pass
  family=socket.AF_INET to HTTPServer.bind().
* HTTPClient now supports IPv6, configurable via allow_ipv6=bool on the
  HTTPRequest.  allow_ipv6 defaults to false on simple_httpclient and true
  on curl_httpclient.
* RequestHandlers can use an encoding other than utf-8 for query parameters
  by overriding decode_argument()
* Performance improvements, especially for applications that use a lot of
  IOLoop timeouts
* HTTP OPTIONS method no longer requires an XSRF token.
* JSON output (RequestHandler.write(dict)) now sets Content-Type to
  application/json
* Etag computation can now be customized or disabled by overriding
  RequestHandler.compute_etag
* USE_SIMPLE_HTTPCLIENT environment variable is no longer supported.
  Use AsyncHTTPClient.configure instead.

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

Really nice work on the new Docs, it was a much needed refresh.

How do you find the time while also working @ facebook?

I really like the new doc pages as well.

They truncate in Safari on the iPhone 3GS though. It's really weird.
It looks like the page just stops loading.

They're actually loaded correctly, it's just that the fixed navigation elements mess up scrolling.  If you scroll with two fingers instead of one, it works.
