 Follow the process below to update all required pieces to bump the version. All these changes are done in a single commit because it makes it clear to git readers what happened to bump the version. It also makes it easy to cherry-pick the version bump onto the `main` branch when tidying up branch history at the end of the release process.

+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`.

 2. Run `towncrier build` to generate the CHANGELOG. The version used by `towncrier` should automatically be correct because of the update to `pyproject.toml` in step 1.
