@cryptoethic As @pitaj has said, this is in our backlog, so it is not available at present. If you need a solution immediately, you can scrub the entire edit history for that post. Delete the key post:<pid>:diffs and all keys that start with diff:<pid> e.g. redis-cli keys diff:123.* | xargs redis-cli DEL

Nobody's done so. In fact, this was a feature requested eons ago! gh#149 Let me know if you find a nice library to handle diffs
