See CVS log, some bugfixes and features.
Main features are setProperty() and internationalization support for YUI Calendar.
Note that internationalization does not relies on Drupal's locale.module, maybe it should, but translating strings such as "S" or "T" is not quite elegant.
Note that this release IS stable, the only reason it's now as beta is because it need some people reporting it working to securely release it as stable.
