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_Post :: top()
- MEOW_Post The top level ancestor of the post, or simply this post if there are no ancestors or the post type is not hierarchical.

Note: this will only return a meaningful result if this post is based on a hierarchical post type.
