2009-09-08
Here is a list of improvements in this version:
  1. New layout. More compact. Hopefully easier to see and enter units. This page looks best in Firefox - Internet Explorer and other browsers like to mangle my layout.
  2. The Enter button works. Press Enter to run the sim.
  3. Speed increase. I redid some code so the sim should run a bit faster now.
  4. New Battle modes. Which means that you can now do Amphibious Assaults.
  5. New Jet Fighters option for 50th Anniversary rules. Before it was just calculating Jet Fighters for both sides. Jet Fighters for everyone!
  6. Submarine's should act correctly now- with preemptive strikes, hitting only water, and interacting with Destroyers.
  7. Bug fix for 50th Anniversary rules where only Transports were left. The sim would hang while the Transports stared each other down forever.
Hope you like it.
