Backward Compatibility and Migration Notes

As usual, before upgrading to this version, be sure to have a working backup of your database(s).

General Notes

If you're running in a multiwiki setup you'll also need to define the property in your xwiki.cfg file if you want to explicitly name some databases to be migrated as the default is now to migrate all databases. Database that are not migrated could not be accessed.

You may also want to import the default wiki XAR in order to benefit from all the improvements listed above.

Always make sure you compare your xwiki.cfg and files with the newest version since some configuration parameters were added. Note that you should add so that XWiki will attempt to automatically migrate your current database to the new schema. Make sure you backup your Database before doing anything.
