A UI-focused release, aims to make Plone more efficient to work with. NOTE: The latest beta release available requires Zope 2.10.3 or a later release in the 2.10.x series. (To avoid any potential confusion caused by the version numbering, please note that Plone 3.0 will run on Zope 2.10.x - this means Zope 2 and Zope 3 in combination, not Zope 3.x exclusively)

Plone 3.0 (Beta) at Plone.org (www.plone.org)

We here at Zope Zone (having just gone Plone) will certainly start to play around with the release but probably won't set our sites on migration just yet.
