From: http://www.theserverside.com/news/thread.tss? Thread_id = 39830

Liferay has released liferay portal 4.0, which brings a revamped fine-grained security model, enterprise taxonomy, delegated and cascading permissions and administration, public and private pages, JSR-170 compliance via jackrabbit integration, and page-level themes to the popular open-source portal application.

The latest version of liferay's JSR-168 compliant open-source portal features a revamped permissioning model which allows assigning of permissions to all portal objects, including viindidual portlets (e.g ., message Board, blog, email) and Portlet elements (e.g ., message Board messages, blog entries ).

With 4.0, administrators can bestow privileges and/or delegate security administration to communities, individuals, and organizations and locations (see below). Community and organization/location privileges cascade to individual users.

Enterprise taxonomy is introduced in 4.0 through "organizations" and "locations," which allow portal administrators to organize content and functionality by general enterprise-wide and division-specific pages. A location can be a geographical subdivision (Europe, U. s. west) or some other entity (Home Office equipment, manufacturing ).

Communities continue to allow grouping by special interest or skill (Organization SS organization), and now support public and private pages. A community's public pages are viewable by any member of the portal community, while private pages are limited to members of the community.

Portlets can also be 'sub-themed': individual users can modify the color, Font, and style of portlets using an intuitive GUI interface. you'll also see we 've ve made overall improvements to the visual UI and workflow in the CMS and other areas.

Rounding out the package are more themes (guis), now assignable to individual pages (previusly assigned to communities), JSR-170 compliance via jackrabbit integration, and additional documentation.

A new version of our website accompanies the release, and the demo is available as always at demo.liferay.net.

We 've gotten some press on this release in network world, which we're excited about.
