- * A function for creating or modifying a post type based on the

+ * Note: Post type registrations should not be hooked before the
+ * {@see 'init'} action. Also, any taxonomy connections should be
+ * registered via the `$taxonomies` argument to ensure consistency
+ * when hooks such as {@see 'parse_query'} or {@see 'pre_get_posts'}
+ * are used.
+ *
+ * Post types can support any number of built-in core features such
+ * as meta boxes, custom fields, post thumbnails, post statuses,
+ * comments, and more. See the `$supports` argument for a complete
+ * list of supported features.
*
* @since 2.9.0
+ * @since 3.0.0 The `show_ui` argument is now enforced on the new post screen.
+ * @since 4.4.0 The `show_ui` argument is now enforced on the post type listing
+ * screen and post editing screen.
+ * @since 4.6.0 Post type object returned is now an instance of WP_Post_Type.
+ * @since 4.7.0 Introduced `show_in_rest`, 'rest_base' and 'rest_controller_class'
+ * arguments to register the post type in REST API.
