What changed, and why it matters
This commit only updates the release signature file (signatures.txt). It refreshes SHA-256 hashes for changelog/history files and adds hashes for two new Q1 firmware release files, plus updates the PGP signature that covers the file. There is no source code change and nothing that directly affects device security.
No action required from a security standpoint; verify the new PGP signature and file hashes through normal release-process checks if auditing the Q1 release.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff is limited to releases/signatures.txt. It updates hashes for documentation files (Next-ChangeLog.md, History-Q.md, History-Mk4.md, History-Mk5.md, History-Mk.md, ChangeLog.md) and adds two new Q1 firmware DFU entries (v1.4.1Q-q1-coldcard.dfu and v1.4.1Q-q1-coldcard-factory.dfu). The detached PGP signature over the file is also replaced. No firmware source, build scripts, or cryptographic logic are modified.
