This update package supplies the advanced updater, which is capable of updating modified installations. Please use the Full Package update method if you have not made changes to core files.
Warning: The advanced update is for expert users that have made custom edits to core files. If you have a standard installation of phpBB that only includes downloaded extensions or styles this update package is not applicable to you and SHOULD NOT be used.
