Version 2.7 completely changed the game's maps - removing some, changing others and adding new ones. As such, I'd suggest moving the current leaderboards to "Legacy Runs" category (v1.9.4 to v2.6.3) and adding a new "Modern Runs" category (v2.7.0 and up).

Also, a lot of new maps have a variable number of players. Should they be run with default number of players (2 or 3) or maximum number of players (5 or 6)?

And... am I blind or did we lose the Rules section? o.O
