I kinda missed this myself. Not sure if it's been posted yet and god knows there's been enough discussions about it on here before, but this update seems to actually have a working lighting preview for Hammer. Seems to generate a really quick, low res lightmap in the preview window. It seems to do the job okay, but nothing too fancy. Thought I'd post it to let anyone know in case they missed it.
Oh, and the raytrace preview still seems to crash like in the version before. Not sure if that's just broken or there's a work around for that.
