The improvements have been mind blowing to say the least. The latest one that has received a lot of attention is the Cycles Rendering Engine. It gives very accurate lighting with minimal effort and utilizes either the CPU or GPU for rendering. The GPU must be CUDA enabled for this option to be available.
