Changelog
The changes worth knowing about, newest first. Small fixes and wording are not listed — this is for the ones that change how the game plays or what the board means.
1.0.0
The first release. The game, a leaderboard whose scores are replayed on the server before they are believed, and the pages around them.
A run is stored as the keys that were pressed rather than as a number, and it is a real score because the server replays it. The guide has the rules as they are.
