I’ve just upgraded the blog to WordPress MU 1.5.1. For a couple of days some features may not work as expected, due to plugin incompatibilities, new options, etc.

I’ve made a .diff patch file to make the upgrade process from the release I was using before (1.3.3) a little bit easier. It’s available here in case anyone finds it useful. If you may find any problems after the upgrade, be sure to disable and remove all plugins, specially from the mu-plugins folder, and proceed to install them one by one.
