How to publish a new release

1. On the main branch, bump the version number in package.json:

   npm version patch -m 'Release v%s'

   Instead of patch, use minor or major as needed.

   Note that this produces a Git commit + tag.

2. Push the release commit and tag:

   git push && git push --tags

   Our CI then automatically publishes the new release to npm.
