Star Citizen has 1.1, the first major update since the Arena Commander module landed.
Star Citizen 1.1 delivers two more achingly expensive ships.
The update also brings a new manual and a new way to access Arena Commander (and later other modules, too), as well as the REC rental system, a dynamic damage system and better character animations.
Probably the most substantial gameplay change is the new landing system; it’s well worth reading up on over on Roberts Space Industries.
If you like your update details dry and detailed, the full patch notes are available.
