Compatibility Notes
-------------------
- [Mixing Option and Result via `?` is no longer permitted in closures for inferred types.][86831]
- [Previously unsound code is no longer permitted where different constructors in branches
could require different lifetimes.][85574]
- As previously mentioned the [`std::arch` instrinsics now uses stricter const checking][83278]
than before and may reject some previously accepted code.
- [`i128` multiplication on Cortex M0+ platforms currently unconditionally causes overflow
when compiled with `codegen-units = 1`.][86063]
