After some work this evening, I was able to merge my changes to PHP-Nuke 5.0 beta 3 into 5b4, and moved the site over to the new code.

The only big news is that forums have been dropped from the base install of PHP-Nuke (for now). The reasons given for the removal were that the forums had a "high number of problems" and the code was supplied by Nuke Add-On, not the PHP-Nuke developer, making code updates difficult. Removing Forums didn't really affect us, there wasn't really anything there yet.

The official announcement can be found here, and the source is also available for download.
