The short version

What changed, and why it matters

This commit changes the Trezor firmware's embedded MicroPython configuration so that detailed error tracebacks are no longer stored in optimized (PYOPT=1) builds. The stated goal is to avoid allocating traceback data in release builds, which can save memory and reduce information exposure if an error occurs. There is no direct evidence in the commit that this fixes an active security vulnerability, but it is a defensive hardening measure.

Recommended action

Treat as a minor hardening improvement. Review the corresponding MicroPython submodule commit to confirm whether traceback disabling was newly introduced or just configured. No urgent action required unless traceback data was previously shown to leak sensitive runtime information.

Disables traceback allocation in optimized/production builds

This commit removes the SHA-1 hashing function from the regular Trezor firmware. SHA-1 is an old, weak hash algorithm that is no longer considered secure for sensitive uses. The change deletes the code that exposes SHA-1 to apps running on…

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.
