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.
Retrieves a field set for this post with the given name.
Note: It is more concise to make use of the __get method overloading to retrieve a set, but this method is a fallback when the field name clashes with a known property of the post. A good example is if you name a field set “content” which cannot be retrieved directly on the object since WOOF_Post has a method named content to retrieve the standard post content.
