*********************************************************************
If you were using attributes/options sort order from previous versions:
    - Make a database backup for security if something gets messed up. 
    - On first load of this version, the sold sort order entries will be migrated to the new core sort order columns.
    - Check your database for success after you loaded the new attributes manager.

    - Uninstall the old product info options/attributes content module and delete the files.
    - Install the core module instead.

Product based Attributes Values sort order support

If you wish to use a product based sort order for Attribute values like in older Attributes Manager-Sort order, you need to modify the queries in the product info options attributes modules.
Change in includes/modules/pi/product_info/pi_options_attributes.php line 68:
order by pov.sort_order
to:
order by pa.sort_order

or

Change in includes/modules/content/product_info/cm_pi_options_attributes.php line 44:
order by pov.sort_order
to:
order by pa.sort_order
