The short version

What changed, and why it matters

This commit updates the vendored rust-bitcoin library inside the BitBox02 firmware from version 0.32.2 to 0.32.7. It is a routine dependency refresh that pulls in several upstream bug fixes and small feature additions, such as support for testnet4 and pay-to-anchor outputs. The commit does not describe itself as a security fix, and the visible changes are mostly API cleanups and correctness improvements rather than patches for an active vulnerability.

Recommended action

Treat as a standard dependency maintenance update. Review the upstream rust-bitcoin 0.32.3 through 0.32.7 release notes for any security-relevant fixes, run the firmware's transaction signing tests, and verify that the renamed Taproot keypair methods in signtx.rs still produce valid signatures. No urgent security response is indicated by this commit alone.
