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 :: types( Array / String $arg )
Array / String $arg
Either a string representing the post type name, OR an array representing args to pass to WordPress’ get_post_types. Note that you CANNOT use the string representation of the arguments for this function, as it will be assumed tat a string is a post type name.
