This change is relevant to plugin developers

The migration helper functions migrate_to_integer_simple_levels and migrate_to_float_simple_levels for SimpleLevels currently apply the scaling factor (if given) every time the migration is run, meaning also to the already migrated value. This means any rule where these helpers are used with a scaling factor will have incorrect values and will have to be manually corrected.

No shipped rules are affected by this.
