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 :: template()
Returns the file name of the current template, sans-extension, if a custom template is attached.
Note: this function does not exhaustively cover the possibilities in the WordPress Template Hierarchy, it is currently used only in more specific cases in MasterPress. This may change in a future release.
