The Plone Team announces the release of Plone 2.0, the next generation of its rapidly growing open source Content Management System.
Plone 2.0 offers significant productivity gains for content managers and developers. It includes an intuitive interface and out-of-the-box features such as time-based content publishing and role-based authoring and publishing. Particularly compelling for many organizations is that Plone is available without licensing costs and offers a similarly stable, feature-rich CMS environment as competing commercial systems costing hundreds of thousands of dollars.
