Moodle 2.5

Unsupported Moodle Version
This version of Moodle is no longer supported and will not receive fixes for security risks.
You are encouraged to upgrade to a supported version of Moodle.

Release date: 14 May 2013

Here is the full list of fixed issues in 2.5.

See New features for a user-friendly tour with screenshots.

Many thanks to all the developers that worked on fixes and features in this release.

Our release process continues to evolve and improve with more testing (human AND automated) than ever before. Thanks especially to the Moodle HQ integration team for tirelessly reviewing and improving all new code, David Monllao for our excellent new behat-based interface testing mechanism, as well as all the QA testers, peer reviewers and issue testers who tested every single addition in Moodle 2.5 (3 times!)


These are just minimums. We recommend keeping all your software updated.

  • Recommended minimum browser: Google Chrome 11, Firefox 4, Safari 5, Internet Explorer 8 (IE 10 required for drag and drop of files from outside the browser into Moodle)
  • Moodle upgrade: Moodle 2.2 or later (if upgrading from earlier versions, you must upgrade to 2.2.9 as a first step)
  • Minimum DB versions: PostgreSQL 8.3, MySQL 5.1.33, MariaDB 5.2, MSSQL 2005 or Oracle 10.2 (oci_native_moodle_package.sql needs to be executed before upgrade on Oracle servers)
  • Minimum PHP version: PHP 5.3.3
  • New PHP extension requirements: GD

NOTE: We will drop support for IE8 in Moodle 2.6 (to be released November 2013). This means IE8 will probably still work for 2.6, but developers will not be required to test their new code on that browser. Moodle, like most of the world's web sites and browser producers, encourages you to keep your browsers current to improve security and functionality while saving us valuable time. (For example see what Google is doing)
