First of all thanks to the CR team and to all the people in SRC for the great suggestions :)
In 3.1 you'll enjoy a new skybox, some fixes to some of the moons like a total redesign of Ilithos and a major upgrade in Droo terrain (hopefully in less than a week). This new terrain is not the only new thing in Droo since now you'll be able to enjoy 2 new drone ships and 2 new launch locations:
Our old friend the main base has been renamed and is now called Herschel Space Center after William Herschel. It is in lat 0 long 0 and has two drone ships nearby so you can land all your rockets in them and also a spawn point in the water near the coast.
The Novoneyra Base named after Uxío Novoneyra is totally surrounded by mountains, in the other side of Droo. Perfect for rovers and planes, the views around the base are spectacular. This is one of the things I'm most proud of.
And finally the South Pole Base, our latest addition, really close to the pole. We thought about calling it the Scott-Amundsen Base or Project Borealis, but since we are undecided we want you to suggest names for this base. Your name may be used in one of the most common launch locations in SR2 in the near future, think it over.
