Changes added to the Small Bets edition of Campfire chat include those on this list: https://github.com/antiwork/smallbets/blob/master/campfire-m...
Notably, the rooms lists appears different in Small Bets chat vs. in the original Campfire, with the "star to pin favorite rooms" mechanism in the Small Bets fork.
Previously, 37signals recently changed the license of Campfire to be FOSS: https://github.com/basecamp/once-campfire
