What changed, and why it matters
This commit updates a signed release manifest file (signatures.txt) for the COLDCARD hardware wallet firmware. It adds cryptographic hashes for two new Q1 firmware files and updates the hash and PGP signature for the ChangeLog. There are no code changes, no bug fixes, and no security-related content in the diff itself.
No action required; this is a routine release signing artifact update. Verify the PGP signature and hashes through normal release procedures if consuming the firmware.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff modifies releases/signatures.txt, a PGP-signed checksum list. It updates the SHA-256 hash of ChangeLog.md and adds two new DFU firmware file entries (v1.3.4Q for q1 hardware) along with a refreshed PGP signature. No source code, build scripts, or security-sensitive logic is changed.
