The latest release of the forum plugin v2.7 is now available. It includes a number of small bug fixes that have been reported over the past few months as well as a couple of new features. You can now optionally have the forum appear with just left blocks, just right blocks, both left and right or no blocks. Additionally you can have the user menu appear as a horizontal navbar instead of the blockmenu. The options are defined in the themes functions.php so if you have multiple themes you can have it change for each theme if requried.
There are no database changes so all that should be required is to replace the changed files or complete directories. Existing sites running version 2.6 need to replace all the plugin files and run the plugin upgrade which just needs to update the version number. Refer to the v2.7_changes.txt file for more details and listing of the changed files.
