// This file keeps track of upgrades to

// Sometimes, changes between versions involve
|
|
// alterations to database structures and other
|
|
// major things that may break installations.
|
|
//
|
|
// The upgrade function in this file will attempt
|
|
// to perform all the necessary actions to upgrade
|
|
// your older installation to the current version.
|
|
//
|
|
// If there's something it cannot do itself, it
|
|
// will tell you what you need to do.
|
|
//
|
|
// The commands in here will all be database-neutral,
|
|
// using the methods of database_manager class
|
|
//
|
|
// Please do not forget to use upgrade_set_timeout()
|
|
// before any action that may take longer time to finish.
