Release Notes: The main change is that the forum is open again, and that you are once again able to submit fleets. Since 1.62 there are only a couple of very minor code changes (the dependency on SDL_gfx has been removed, and the game no longer draws a circle with a radius of 1 when displaying the range of a ship without a weapon).
Release Notes: The world arena is now much bigger and ships now have momentum. There have also been a large number of minor feature enhancements and bugfixes.
Release Notes: Various gameplay changes were made. A much larger battle arena was implemented, ships now have momentum, capital ships can move, and it is harder for bombers to outrun fighters. A large number of improvements were made to aid tournaments. Various minor feature enhancements were made and a few minor problems and bugs were fixed. AI error messages are now dealt with more effectively.
Release Notes: This release adds a large number of improvements and a few bugfixes. Note that the settings file has changed, so Linux users need to delete ~/.galaxyhack before installing. Unfortunately, a precompiled Linux binary for 1.0 will not be available until a user submits one.
Release Notes: Network play has been removed. Instead, you can download other fleets to test yours against from an online database. You are encouraged to submit your own. Because of this, old fleet data files will no longer work. Old unit files and AI scripts will still work fine. It is now possible to script simple arithmetic in AI scripts: +, -, *, /, ++, and --. There is a new variable that allows you to check the number of units left in the group, and a new variable that allows you to check how many torpedos are already flying towards a given capital ship. There are various minor changes/improvements.
