As a quick note, we will be updating our Moodle servers soon. We are scheduled to update our test server May 15, our PD server May 22, and our K-12 server June 26.
We are still deliberating whether we will upgrade to Moodle v2.8 or v2.9. v2.9 is being released May 11, so we will test it out to see if there are any potential bugs to be worked out (typically those are fixed within the first 2 weeks of release, meaning that the PD server will by just on the cusp of being bug-free. If we feel v2.9 isn't quite ready, we'll go instead to v2.8.
Here is a look of the new features in v2.8. Note, the following is an official playlist of 8 videos from Moodle.
