Beaglebone Black and LCD4

I have been looking to buy a beaglebone black board and LCD4 cape.

I believe the most current beaglebone black version is A6A. Is there a new revision in the works?

Which of the 4 inch LCD displays with touch goes with the latest beaglebone black. I see the circuitco makes the LCD4 displays.

Some insight is greatly appreciated.

Thanks
