The short version

What changed, and why it matters

This commit turns off several unused features in the MicroPython interpreter that runs on Trezor hardware wallets. It is a hardening change that reduces the amount of code available to an attacker, but it does not by itself fix a known, exploitable bug. The commit message explicitly calls it a routine cleanup ('chore') and says it needs no changelog entry.

Recommended action

Treat as a low-risk hardening improvement. No urgent action is required, but verify that downstream firmware and emulator builds still compile and that no legitimate application code depends on the disabled features (str.center, weak links, or uctypes in Bitcoin-only mode).

Security signals we found

01

Disables MicroPython module weak links, removing a dynamic module-resolution mechanism

02

Disables the str.center builtin, removing a string-formatting code path

03

Makes uctypes conditional on !BITCOIN_ONLY, removing a C-struct introspection module from Bitcoin-only builds

04

Commit is tagged as routine maintenance ('chore') with '[no changelog]'

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.
