Hi Andrew,
It looks like the EDK II CI agents were updated to use NASM 2.15.05 back in
March of this year.
https://github.com/tianocore/edk2/blob/0ecdcb6142037dd1cdd08660a2349960bcf0270a/BaseTools/Bin/nasm_ext_dep.yaml
So I think the only remaining task is to update the developer documentation to
require NASM 2.15.05 as the new minimum required version.
Do you agree?
Mike
