Over spring break I got an urgent bulletin from Moodle stating that they had fixed some bugs and issued an update. These are fairly common and I usually don't do anything about them until the next break in classes, but since this one came during a break in classes I went ahead and updated. We are now on version 2.0.8.
On a related note, official support for Moodle 2.0 ends in June. This means that we will no longer get security updates unless we update, thus over the summer we will be moving to Moodle 2.2, or possibly 2.3 if they release it by then. This will be a major upgrade, unlike the minor one I just applied. Please take backups of your courses before you leave for the summer.
