As in previous years we will be upgrading Moodle at the end of summer, ready for the new academic year. After a period of testing, the upgrade itself is likely to happen in the third week of August. More information will be disseminated here and through various other communication channels in the next few weeks. If you can't wait to find out about some of the general new features in store for you, head over to the official moodle site, by following this link: http://docs.moodle.org/26/en/New_features.
And watch this space!
