Plone 2.5 was released yesterday.  This is the first "infrastructure" release under Plone's new release plan and version numbering scheme, which includes alternating "infrastructure" and "feature" releases.

Most of the new stuff in Plone 2.5 is underneath the surface, where the first big chunks of Zope3 plubmbing are now in place -- most notably the PlonePAS user authentication framework, which makes it easy to have Plone authenticate and store member properties in external data sources and the new GenericSetup system for creating and configuring sites.

There's also a slew of minor bugfixes and usability enhancements.

Congratulations and thanks to all those who worked so hard to get this out the door.  Onwards to Plone 3.0!
