Note on releases
Whenever Liquid War is released, I usually pass the good news to Freshmeat ( http://freshmeat.net/projects/liquidwar/ ). Then all releases are accessible from the main download page, which is http://www.ufoot.org/liquidwar/v5/download.
Releasing the game takes time, for I want all binaries to install properly and sources to compile cleanly. Therefore there might be some delay before the time coding is over and the time a release is actually ready. So for impatients and/or for people who need to test out the very latest versions (eg someone who wants to compile the game on a new platform), it's possible to access the source repository directly.
About GNU Arch
I use GNU Arch (Tom Lord's Arch in fact, http://www.gnu.org/software/gnu-arch/ ) instead of the previously used CVS. Indeed, tla has some very fancy features such as signing patches with gpg, and I'm tired of suffering CVS limitations.
So FYI the previously active CVS repositories, on Sourceforge and Savannah, are currently unmaintained.
How to get latest releases
Before using GNU Arch I recommend that you read the excellent Arch tutorial http://regexps.srparish.net/www/tutorial/html/arch.html if you are not familiar with tla. I admit there's a steep learning curve, but it's yet clear and understandable.
Typical commands to get the latest version might be:
tla register-archive http://arch.sv.gnu.org/archives/liquidwar/ tla -A firstname.lastname@example.org get liquidwar--stable
