This year is a big jump in Moodle versions for us at Hope, as we upgrade from Moodle 2.7 to Moodle 3.1. Here are some summary videos from Moodle HQ about what's new in the all the versions since 2.7. Each video is about what's new relative to the previous release, so the change experienced here at Hope will be the accumulation of all of the changes in these videos.

Moodle 2.8

Moodle 2.9
