Masterpress 1.3.6 is a compatibility release. It resolves an edge case with shared fieldsets not working for MySQL 8 when the fieldset is limited to more than 1 post type or taxonomy or excluding any post types or taxonomies.
MEOW_FieldSetCollection :: sort_to( String $field, Array $values, String $order = ASC )
Returns a field set collection of items sorted by the given field in the order of a supplied values map. This is a difficult concept to explain, so please refer to the example!
