The short version

What changed, and why it matters

This commit updates the Pillow image-processing library used by Trezor's firmware build tools from version 12.1.1 to 12.2.0. The change is a routine dependency patch intended to fix a security alert flagged by GitHub Dependabot. It only touches the lock file that records which exact package version is downloaded, so it is a defensive fix rather than a change to Trezor's own security code. The actual risk depends on what vulnerability Dependabot reported, which is not described in the commit itself.

Recommended action

Treat as a standard dependency hygiene patch. Verify that the project uses Pillow only in build/test tooling, confirm the fixed Pillow release addresses Dependabot alert 121, run the existing test suite, and keep dependency scanning enabled. No firmware-side mitigation is needed.

refactor(crypto): pass static public key to `noise_xxpsk3_*_init()`

This commit changes how a cryptographic library sets up secure connections. Previously, the code automatically calculated the public key from the private key. Now, the caller must provide the public key directly. This is a code-quality ref…

refactor(crypto): change order of parameters

This commit simply reorders the arguments of an internal function called dh() and updates every place that calls it. The actual math and security behavior are unchanged; it is a code cleanup with no security effect.
