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.
WOOF_Taxonomy :: title()
An alias of the WOOF_Taxonomy::plural_label method to retrieve the plural-form of the taxonomy name. If this is not set, the method will infer one automatically by titleizing the name of the taxonomy.
