Moodle version

Moodle version with (build number) and copyright

The version of Moodle which your site is using can be found if you login as an administrator and go to Administration > Site administration > Notifications.

For Moodle sites with the English or German language, if you are a regular teacher with no admin access, you might be able to find your Moodle version by clicking on "Moodle docs for this page" at the bottom of any Moodle page when logged in. If your admin has allowed this link to display, you should be taken to the documentation for your version of Moodle. Look at the number in the URL e.g. 29 or 31 which mean you are using Moodle 2.9 or 3.1 respectively.

Note: If your Moodle site uses a language other than English or German, you are out of luck with this tip.

For a list of all past Moodle versions, see dev:Releases.

Version.php file

Your exact Moodle version may be obtained by viewing the file moodle/version.php in a text editor. Here is a typical version.php:

<?php

// MOODLE VERSION INFORMATION

// This file defines the current version of the core Moodle code being used.
// This is compared against the values stored in the database to determine
// whether upgrades should be performed (see lib/db/*.php)

    $version = 2007101580.00; // YYYYMMDD      = date of the 1.9 branch (don't change)
                              //         X     = release number 1.9.[0,1,2,3,4,5...]
                              //          Y.YY = micro-increments between releases

    $release = '1.9.8+ (Build: 20100512)';     // Human-friendly version name

?>

Note: You cannot view the contents of version.php in your browser - you must use a text editor.

Discovering Version programmatically

The above variables are copied into the $CFG global object. If you are writing custom code for Moodle you can access $CFG->version and $CFG->release.

IF you have system administrator level of account, you can also use the Site administration block => Server => Environment and it will show you which Moodle 2.x code base you are using.
