What's new in Tornado 3.2.2 =========================== June 3, 2014 ------------ Security fixes ~~~~~~~~~~~~~~ * The XSRF token is now encoded with a random mask on each request. This makes it safe to include in compressed pages without being vulnerable to the `BREACH attack `_. This applies to most applications that use both the ``xsrf_cookies`` and ``gzip`` options (or have gzip applied by a proxy). Backwards-compatibility notes ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * If Tornado 3.2.2 is run at the same time as older versions on the same domain, there is some potential for issues with the differing cookie versions. The `.Application` setting ``xsrf_cookie_version=1`` can be used for a transitional period to generate the older cookie format on newer servers. Other changes ~~~~~~~~~~~~~ * ``tornado.platform.asyncio`` is now compatible with ``trollius`` version 0.3.
