20w14∞ (labeled as 20w14infinite in the launcher, and 20w14~ in game) is an April Fools' joke snapshot, supposedly the first and only snapshot for the "Ultimate Content" update, released on April 1, 2020, which adds new procedurally generated dimensions that randomize existing elements of the game and several ways to access them. 20w14∞ is a fork of 20w13b, which was the most recent snapshot at the time.
