- Use the Rust function path for `wrap_pymodule!` of a `#[pymodule]` with a `#[pyo3(name = "..")]` attribute, not the Python name. [#2081](https://github.com/PyO3/pyo3/pull/2081)
- Fix panic in `#[pyfunction]` generated code when a required argument following an `Option` was not provided. [#2093](https://github.com/PyO3/pyo3/pull/2093)
- Fixed undefined behaviour caused by incorrect `ExactSizeIterator` implementations. [#2124](https://github.com/PyO3/pyo3/pull/2124)
- Add missing FFI definitions `_PyLong_NumBits` and `_PyLong_AsByteArray` on PyPy. [#2146](https://github.com/PyO3/pyo3/pull/2146)
