Facebook has recently (and very quietly) removed the edited tag on posts that have been amended by admins. When the edited tag was visible, it drew attention to changes so that users could choose to view a complete history of posts edited by admins.
View a posts edit history
Even though the edited tag has been removed from posts it is still possible to view a history of edited posts.

Despite the removal of the tag on posts, the edited tag still appears underneath comments , which just begs the question, “why the change Facebook?” No reason has been offered so far…
