So yesterday saw us upgrade from the 11-20 build to the 12-13 build of WordPress MU. The 12-13 build differs significantly from the 11-20 build. In particular new fields were added to some DB tables and new functions were added to wpmu-functions.php. This caused some problems as the update script didn’t update the DB tables and I had to do that manually. Also the new functions caused a problem for the Admin panel as a new function was added and the patched file I was using from ITDamager didn’t have the function, but that was easily fixed by copying over the new wpmu-function.php.
There is some added functionality in the new version. Most notable for the user is the ability to upload mp3 files. This will allow users to Podcast with their blog. This should allow us to conduct an interesting project with Mark Pearson and a faculty member from Earlham.
