Using ext4 usb drive to go to 13.1.0

You are correct that I am confusing things.

12.1.0 os21 has Q4D17 (
http://download.laptop.org/xo-1.75/os/official/12.1.0-21/21021o2.packages.txt
).

13.1.0 os3 has Q4D21 (
http://build.laptop.org/13.1.0/os3/xo-1.75/31003o2.packages.txt - os1 & os2
also have similar).

For some reason I keep ending up off-by-one while trying to parse our new
versioning scheme; sorry.
