It’s come to our attention that administrators of some Moodle sites may have missed out on our usual announcements about important fixes in our most recent stable releases.
Among the improvements there are very important security fixes for serious problems which may allow users to gain privileges or change data improperly.
We strongly recommend you upgrade your Moodle site to one of the most recent stable versions as soon as you can. Since these stable releases only fix bugs and don’t introduce new features there should be no disruption to your production sites (so please don’t put it off!).
To get the very earliest notification of these issues in future via direct email please make sure you REGISTER your site, using the Registration link in your Site Administration pages in your own Moodle site.
The same notifications are posted publicly a week later in our Security Announcements forum and in the release notes.
Note: If you are using our MoodleCloud service you don’t ever need to worry about these: MoodleCloud sites are always running the most recent versions of Moodle.
