Several weeks ago we announced the compatibility of Liferay 5 with the final draft of the spec. and now it's been declared officially final. Thanks go to Stefan, the spec lead, for all his hard work during the last weeks dealing with legal and administrative stuff to make this possible.

I recommend you all to download and read the spec, because it has many interesting additions: Inter-Portlet Communication, resouce serving (very useful for AJAX apps among other things), filters, and more.

Brian just passed the TCK once again and .... yes we are still 100% compliant :)
