Undo, for words
Image history made it easy to go back to an earlier picture. Captions now work the same way in today's post editor.
What's new
A "Caption history" button lists earlier versions of your caption, newest first, with a preview and when each was made
Versions Native wrote are marked "Created by Native", so you can tell them from your own edits
Click a version to restore it. The one you left stays in the list, so you can switch straight back
Each channel's caption has its own history. The button shows once there is more than one version and the post is still editable
The button sits next to the copy button under the caption on desktop, and beside image history on your phone
