Fires actions related to the transitioning of a post's 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 {@see 'transition_post_status'} action, as well as the dynamic hooks {@see '$old_statusto$new_status'} and {@see '$newstatus$post->post_type'}. Note that the function does not transition the post object in the database.

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.

	 * Please note: When this action is hooked using a particular post status (like

	 * Therefore, if you are looking to only fire a callback when a post is first
	 * transitioned to a status, use the {@see 'transition_post_status'} hook instead.
