Packaging
- Extend macOS build flags to iOS, tvOS and watchOS. [436](https://github.com/PyO3/setuptools-rust/pull/436)
- Support Python 3.13. [446](https://github.com/PyO3/setuptools-rust/pull/446)
Changed
- Add `SETUPTOOLS_RUST_PEP517_USE_BASE_PYTHON` environment variable to use the base interpreter path when running inside a virtual environment to avoid recompilation when switching between virtual environments. [429](https://github.com/PyO3/setuptools-rust/pull/429)
- Delay import of dependencies until use to avoid import errors during a partially complete install when multiple packages are installing at once. [437](https://github.com/PyO3/setuptools-rust/pull/437)
- Deprecate `--build-temp` argument to `build_rust` command (it does nothing). [457](https://github.com/PyO3/setuptools-rust/pull/457)
