"Two minute Papers" has made a great video about a new algorithm, that has the capability to speed up liquid simulations by up to 27 times! They finally developed an algorithm that runs on Gpus and is able to work without a fixed bounding box. These improvements alone, were able to reduce baking times by an order of magnitude.

If so, this could be an absolute game changer.
