I still don’t see an option to toggle public edit history in my preferences, but I also can no longer click on another user’s “pencil” icon and see their edits so it at least appears to have the status quo from before (other than for the likely small amount of users that opted into this feature).
Anyway thanks for the quick action here. Part of the problem with what had happened was that anybody who had previously not consented to having their edit history public now had it public even for old posts and this could come at quite a surprise for those of us that care about this.
