+1. Replace all instances of the PyO3 current version and the with the new version to be released. Places to check:
    - `Cargo.toml` for all PyO3 crates in the repository.
    - Examples in `README.md`
    - PyO3 version embedded into documentation like the README.
    - `pre-script.rhai` templates for the examples.
    - `[towncrier]` section in `pyproject.toml`.
