NVIDIA Ampere graphics cards support.
Multilight is now supported by the GPU engine.
Multi-GPU dynamic balance. Less samples are expected from cards that had less performance in past rendering passes.
Emitter + BSDF now works in GPU. It is restricted to one emitter per material.
Samples rebalance: Threads of one pixel can help other pixels if they need to. This helps that the image sampling level is more homogeneous. This can make that, in some scenes, Maxwell will require more time to reach the same SL, but more complicated parts of the image will have less noise at the same SL. Also, less computing power will be invested in easy parts, like the sky. In general, the computing power will be used more efficiently.

Speed improvement in multi-gpu. [This one may not be public depending on final test] [5.1.2.34] [Please check if fire first response has become too slow]
Improved the way in how certain calculations are done within the GPU engine that should help minimize certain precision issues regarding two surfaces being too close to each other and far away from the camera. (i.e. putting an emitter too close behind an AGS could make the rays skip the emitter if they are far from the center of the scene).
Render Region and Blow-up Region are not supported in the GPU engine, now the region is reset to Full Frame before the render starts.
