Version 2.90 of the Mars Simulation Project has been released.
2.90 adds salvaging of equipment, vehicles and buildings to the simulation. Settlers can now both build and tear down buildings to rearrange their settlements how they choose.
2.90 also has a new Nimbus look & feel based on Lars Christensen's work. This requires a Java 6 update 10 or newer virtual machine to run the application.
