What changed, and why it matters
This commit only updates the release signature file. It adds two new cryptographic hashes for recently built firmware files and refreshes the PGP signature that covers the file. There are no code changes, no bug fixes, and no security-relevant behavior changes in the firmware itself.
No action required; verify the new PGP signature and hashes through normal release procedures if auditing the signed release list.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff modifies releases/signatures.txt, appending SHA-256 hashes for 2026-03-05T2052-v5.5.0-mk-coldcard.dfu and its factory variant, and replacing the detached PGP signature. This is a routine release-signing operation; no source code, build scripts, or documentation content changed.
