Moodle 3.7.1, 3.6.5 and 3.5.7 have just been released. These are now available for download via https://download.moodle.org or Git.
All released minor versions include fixes for security vulnerabilities. We highly recommend that you upgrade your sites as soon as possible. Upgrading should be very straightforward.
Administrators of all registered Moodle sites will receive an email with details of the security fixes and we'll publish these more widely next week.
The release notes for each version can be found here:
Please see the releases page for more details.
