I installed the 1.8 update on my BMCC before they took it down. Seems to work great, a little unsettling that they took it down though, but works perfectly so far. The best part is that the image quality improved a lot, with the new debayering! No more aliasing. Here are some comparison images. All pictures are a 300% crop.
