What changed, and why it matters
This commit simply removes the digital signatures and file hashes for a previously listed firmware release (version 5.4.4 for Mk4 and 1.3.4Q for Q1) from the project's release signatures file, and updates the PGP signature covering that file. It is a release-management rollback of a 'gold' release candidate, not a code change. There is no firmware source code modification, no bug fix, and no security patch in this commit.
No security action is required for this commit itself. Users who may have already downloaded the retracted v5.4.4 / v1.3.4Q firmware files should follow any guidance Coinkite publishes separately about why the release candidate was undone and whether they should reinstall an earlier signed release.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff modifies only releases/signatures.txt. It deletes four SHA-256 entries (ChangeLog.md hash plus two Mk4 DFU files and two Q1 DFU files for 2025-09-26 builds labelled v5.4.4 / v1.3.4Q) and replaces the ChangeLog.md hash with a new value. The detached PGP signature over the file is also refreshed. No source files, build scripts, or cryptographic primitives are changed.
