I figured that it was about time I got the next release out the door, so here's 0.5.99 Beta 3.
(thanks to iku for pushing me to do it)
The Win64 portability issue mentioned by szo has not yet been fixed.
MH's problem with the world not rendering on an old DELL has not been fixed yet, either.
I was working on getting global fog working properly when not using multi-texturing, but ran into a nasty wall with instanced brush models (ammo boxes etc). I already have a plan for how to get it going, but I didn't want it to hold things up.
MH: I had a look at the gl_conspin code and the main renderer code: it just doesn't make sense that gl_conspin would *fix" things. When I've got fog sorted (hopefully really soon), Ill be able to concentrate on it more.
