New Moodle versions were released recently. Moodle 2.5.2, Moodle 2.4.6 and 2.3.9 are all out and available for download to upgrade your sites.
For 2.5.2 you can look forward to a number of changes and enhancements, including better TinyMCE functionality on iOS, better UX for delecting comments and improved display of resources and activities on and in the course pages (folders display their names, links to resources visible only for the right roles, and markup for question category descriptions).
