Plone 2.5 Released
Plone 2.5 was released on the 16 of June. This is the first "infrastructure" release under Plone's new release plan and version numbering scheme, which includes "feature" releases and alternating "infrastructure" with a focus on getting Plone ready for the future. This means integrating Zope 3 technologies where sensible, and utilizing new technology from CMF as much as possible. The long term goal is to make the distinction between Plone as end-user product and Plone as infrastructure more clear.
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 new GenericSetup system for creating and configuring sites and the PlonePAS user authentication framework, which makes it easy to have Plone authenticate and store member properties in external data sources.
There's also a slew of minor bugfixes and usability enhancements.
This release requires Zope 2.8.7 and Python 2.3.5+ or Zope 2.9.3+ and Python 2.4.2+.
