We are happy to announce that Vertex 4 for Joomla is now out of beta, stable and ready for download. You can head on over to the free templates area under the Vertex Joomla template and grab the patch to upgrade your existing Vertex site to Vertex 4. Again Vertex 4 is completely backward compatible with Vertex 3 so you can continue using your old Vertex 3 templates with Vertex 4!
You can read out more about the latest additions and features in our previous blog post here: http://www.shape5.com/blog/Vertex-4-Beta-Has-Been-Released.html
NOTE: If you have the BETA version of Vertex 4 installed be sure to upgrade with this stable patch as updates were made and several bugs squashed during the process.
