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_Term :: parent()
- An object representing the parent term, if it exists, or this term object if there is no parent, or the taxonomy is not hierarchical
Retrieves the immediate parent term for this term.
Note: this will only return meaningful results if the term is based on a hierarchical taxonomy.
