/**
- * Transition the post status of a post.

*
- * Calls hooks to transition post status.
+ * When a post is saved, the post status is "transitioned" from one status to another,
+ * though this does not always mean the status has actually changed before and after
+ * the save. This function fires a number of action hooks related to that transition:
+ * the generic 'transition_post_status' action, as well as the dynamic hooks
+ * `"{$old_status}_to_{$new_status}"` and `"{$new_status}_{$post->post_type}"`. Note
+ * that the function does not transition the post object in the database.
*
- * The first is 'transition_post_status' with new status, old status, and post data.
- *
- * The next action called is 'OLDSTATUS_to_NEWSTATUS' the 'NEWSTATUS' is the
- * $new_status parameter and the 'OLDSTATUS' is $old_status parameter; it has the
- * 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' – or some other status – to 'publish'. However, if a post is already
+ * published and is simply being updated, the "old" and "new" statuses may both be 'publish'
+ * before and after the transition.
*
