-We use an experimental in-house tool for managing releases.

-1. Install `rooster`: `pip install git+https://github.com/zanieb/rooster@main`
-1. Run `rooster release`; this command will:
-    - Generate a changelog entry in `CHANGELOG.md`
-    - Update versions in `pyproject.toml` and `Cargo.toml`
-    - Update references to versions in the `README.md` and documentation
-1. The changelog should then be editorialized for consistency
-    - Often labels will be missing from pull requests they will need to be manually organized into the proper section
-    - Changes should be edited to be user-facing descriptions, avoiding internal details
-1. Highlight any breaking changes in `BREAKING_CHANGES.md`

+1. Update the version with `rg 0.0.269 --files-with-matches | xargs sed -i 's/0.0.269/0.0.270/g'`
