The /undo feature was experimental, and we decided to remove it. The decision was based on the fact that it was seeing relatively little usage, and its implementation was causing pretty significant problems for many users — including those who didn't use the feature.

If you'd like to see a feature like this, please open a feature request and describe the functionality you'd like to see. (Or, for those of you who encounter this issue later, search for an existing feature request and upvote or add to it.)

This is surprising to me and unfortunate.

I was very excited when the /undo feature was added because before that I had to type "undo the last change you just made".
Now I'm back to doing that again, or is there an obvious thing I can do to rollback a turn?

My favourite command's gone. Can you /undo this please ? 😂
