Simpocalypse 1.3.0 released

Version 1.3.0 is out today, and besides some minor improvements to the user interface, there's really only one thing to see: Simpocalypse now keeps track of the complete history of the simulation, and allows you to go back in time to see how your epidemic developed. We've been surprised by just how helpful this feature is for understanding the model, so we decided to release it as soon as possible. We're still working on additional improvements, so keep watching!
