- * The first is 'transition_post_status' with new status, old status, and post data.

- *
- * The final action is named 'NEWSTATUS_POSTTYPE', 'NEWSTATUS' is from the $new_status
- * parameter and POSTTYPE is post_type post data.
+ * For instance: When publishing a post for the first time, the post status may transition
+ * from 'draft' â or some other status â to 'publish'. However, if a post is already
