The version shipped is whatever was available when your particular bird left the factory. Who knows how long it took to get to your dealer and how long it has been in his shelf. If you are new to the product, I would update to the latest firmware available when you get it, that way you will have the latest bug fixes and the advantage of all the manufacturers improvements and features. The product does not upgrade itself in transit. The general rule is newer firmware will work better than older firmware.
Be sure to download the latest manual as well. Some of the practices are different that what has been previously released.
