The short version

What changed, and why it matters

This commit updates a third-party Python cryptography library used by Trezor's firmware build tools from version 48.0.0 to 48.0.1. The change is a routine dependency patch triggered by an automated security alert (GitHub Dependabot). It does not modify Trezor device firmware code itself, only the build/development environment. The commit message says it fixes a Dependabot alert, but the exact vulnerability details are not included in the commit or supplied references.

Recommended action

Verify the upstream cryptography 48.0.1 changelog for the specific fixed issue and confirm the updated lockfile is deployed to all build/CI environments. No immediate action is required for device firmware users, but development and CI systems should use the patched version.

feat(core): support dev-signed definitions on non-production builds

This commit moves the public keys used to verify coin/token definitions from Python code into a new Rust module. It also makes development-signed definitions accepted on non-production builds, similar to an existing feature for translation…

fix(core): update fixtures

This commit only refreshes test data files: it updates a translation signature metadata file and regenerates UI test fixtures. There is no code change, no security fix, and no indication of a vulnerability being addressed.
