Release procedure (for developers):

Ensure every is-at-least invocation passes a stable zsh release's version number as the first argument
For minor (A.B.0) releases:
- Check whether the release uses any not-yet-released zsh features
Check open issues and outstanding pull requests
Confirm make test passes
- check with multiple zsh versions (easiest to check GitHub Actions: https://github.com/zsh-users/zsh-syntax-highlighting/actions)
