* This file keeps track of upgrades to the self completion block
* 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.
