Yesterday, Liferay released version 5.1.0 of Liferay Portal [download]. This latest release incorporates a number of new features, including features and bugfixes contributed from Project WebSynergy (e.g. the portlet container).
As of 5.1.0, Liferay is now bundled with GlassFish v2 and GlassFish v3 [Download Now]! It's a lightweight (33% reduction in size), platform-neutral download that demonstrates the power and modularity of GlassFish v3, with a real-world app. Kudos to the Sun and Liferay team!
