// This file keeps track of upgrades to Moodle.

// alterations to database structures and other
// major things that may break installations.
//
// This file specifies the current version of
// Moodle installed, which can be compared against
// a previous version (see the "config" table).
//
// To do this, visit the "admin" page.
//
// The upgrade function in this file will attempt
// to perform all the necessary actions to upgrade
// your older databases to the current version.
// If there's something it cannot do itself, it
// will tell you what you need to do.
