Liferay 4.0.0 Final Released!

Liferay Portal 4.0.0 has been released, with fine-grained permissioning, support for Geronimo, Websphere 6, and Weblogic 8.1SP5, Alfresco integration, JSR-170 support, full-page caching, and more. It includes many bundled portlets and themes, and can be deployed on most application server/database combinations, including deployment in servlet containers (as opposed to a full application server).

Liferay also supports single-signon, user customization, and a number of other useful features. Liferay is licensed under the MIT license.

You can find an online demo of Liferay, and a roadmap for future development is available.
