Twitter is adding an edit button, the company said yesterday. The "Edit Tweet" option will become available "in the coming months" to users of the paid Twitter Blue subscription, with a potential rollout to other users later on.

The announcement came shortly after Elon Musk joined the Twitter board of directors and polled users about whether they want an edit button. But Twitter said the edit button has been in the works for months.
