How to make a new release

Add a new entry to CHANGELOG.md (I normally use the new release page to generate a changelog, then manually group)
1. Follow the existing format: Fixed, Added, Updated, Deprecated, Removed, New Contributors sections, and the full changelog link at the bottom.
2. Mention only user-visible changes - improvements to CI, tests, or development workflow aren't noteworthy enough
3. Version bumps are generally not worth mentioning with some notable exceptions (like pyo3)
4. Group related PRs into one bullet point if it makes sense
manually bump versions in Cargo.toml files in the repo
make a new PR with the above changes, get it reviewed and landed
make a new release on Github, create a new tag on publish, and copy the contents of the changelog entry in there
after publishing, check out the repo at the new tag, and run cd native; cargo +nightly publish -Z package-workspace -p libcst_derive -p libcst
