Automobilista 2 - Update V1.5.5.5

Reiza Studios deployed Update V1.5.5.5 for the Automobilista 2 racing simulator, bringing you the final complementary update to this Le Mans development cycle.

The update is wrapping up all art development of the track with the remaining trackside objects. It also wraps up all V1.5.X physics developments and introduces another batch of AI developments which should once more bring another notable improvement in their ability to race each other as well as the player.

Besides some minor hotfixes, this should be the last public update to AMS2 for at least a couple of months as Reiza will switch focus to new longer-term developments.

Check out the changelog for all the details.
