A number of people have been writing me about what appeared to be a memory leak in jit.freenect.grab. Indeed, there was. It’s been found, and as far as I can tell, it’s been squashed. If any of you wish to compile the external on your own, please beware that it is the OSX version of libusb that leaks. Be sure to read the libfreenect README carefully to find out how to patch the problem.
I also get people asking me about a Windows external. Unfortunately, it’s not going to happen soon. At least unless some kind soul does the work for us, because I just don’t have enough time to dedicate to a port.
