Each update has all the previous updates fixes, no need to download each update to get those features.
Thanks PB_PM. I asked because I intend to skip the current update. I'm satisfied with the way my AF-ON back-button currently works and see no reason to change...although I can understand why others might want the modification.

I did the firmware update and my Transcend 400x 32GB CompactFlash still works.
Whew.
