Users can now edit comments they have posted to the site, instead of having to delete it and comment again. The old method was annoying because your friend would get two notifications and you'd have to re-type everything even for a basic typo.
The edit option looks like a small pencil on the right side of the comment. Clicking it will bring a dropdown menu with the options to edit or delete as usual.
Additionally, the social networking giant will be "showing the editing history for a comment so that subsequent commenters or likers have the full context of the conversation."
