What changed, and why it matters
This commit only updates the signed release checksum file (signatures.txt). It adds hashes for two new firmware files and updates hashes for four changelog files, then re-signs the file with a PGP signature. There are no code changes, no bug fixes, and no security-relevant modifications visible in the diff.
No action needed from a security-review standpoint; this is a routine release-signature update. If reviewing the release, verify the new DFU binaries and changelog hashes against the vendor's published release notes.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff is limited to releases/signatures.txt. It updates SHA-256 hashes for Next-ChangeLog.md, History-Q.md, History-Mk4.md, and ChangeLog.md, and adds hashes for two new DFU release binaries (v6.4.0X for mk4 and v6.4.0QX for q1). The PGP signature block is refreshed. No source code, build scripts, or cryptographic logic is changed.
