What the source says changed

No official source in the set states what changed in the text; the number and title are as listed.

Why this disposition

252.204-7020 is absent from every DoD RFO deviation attachment and its heading is struck through in the DAR line-out; the DFARS Part 240 deviation prescribes 252.240-7997 with the identical title "NIST SP 800-171 DoD Assessment Requirements". No official table states the mapping, so it rests on title identity. Note: the DFARS Part 212 deviation (2026-O0028, 18 Dec 2025) still lists 252.204-7020 at 212.7205(e).

Confidence: medium. Read from official text by an identical title; no official table states this mapping.
