This release introduces OpenID 2.0 support, XRDS discovery, much more robust HTML discovery, and example provider and relying party implementations. It also changes the API and, although the old code is still there for compatibility, its use is strongly discouraged and the code using the old API will not benefit from most of the improvements.
