Better late then never. Days ago insellium did a lot of work to seperate all the unneeded textures from the normal release and moved it into a mapping pack. So if you are a mapper you download the release, the mapping pack, Netradiant and the q3rally game pack. When you release a map you have to put the textures you used in your map.pk3.
If you only want to play, download the release and have fun. Your advantage is the heavily lowered filesize (~370MB -> ~150MB) of the release.
A “new” nightly is also ready for download. The server will be updated latest tomorrow. Now there are only little steps until release of 0.0.3.0. Some fixes. My new Domination Map. Packing the release. Stuff like this.
