Please thank all people who have contributed to this Spring release:
Kloot, trepan, quantum, SJ, Yeha, malric, AF, Vincent Pelletier, Viktor Muraviev, KDR_11k, M2, yuritch, FLOZi, submarine, semi, det, imbaczek, zizu, Betalord, Auswaschbar, ILMTitan
Also thanks to everyone who helped testing the sort-of-weekly development builds


Notes:
- If there's lots of disk activity when starting Spring or TASClient.exe after a fresh install, it may be caching your mods and maps. This can take quite a while if you have many maps and mods.
- The installer has been hotfixed some times in the first hour(s) after it was posted. If your installer is corrupt, it may be because it was updated while you downloaded it. Sorry for this, redownloading will fix it.
- The new unit/feature highlight widget requires an image file that
was not packaged along with 0.75b1. You can get a suitable image
file from: http://trepan.bzflag.bz/spring/highlight_strip.png , then move
the image file into your: $SPRING/LuaUI/Images/ directory.
Have fun!
