Waht news of 2.2 beta or otherwise? When will 2.2 be available on os x

Title says it all… I have some issues with CUDA on OS X and want see it these are fixed in 2.2 beta or later. I could look at 2.1 but if the release is imminent then I can save myself some time. I am wanting to release some code but I need to resolve/document these issues first.
