Just a few minutes ago we released a new version 4.0.0b2
This version includes Team Notices, Forums, Team Forums and much better support for all you poor Internet Explorer users.
Anyone using the previous version 4.0.0b1.2 can upgrade their database using the upgrade script in the scripts folder, but as usual I recommend a fresh start (hey, it is beta software after all). There is also a separate script for installation of the help content. See the installation instructions on the wiki for more information about that.
Feel free to direct installation problems to the installation support forum
This new version is now available for standard download from the Omnium Open home page.
