## For maintainers
### How to publish a new release
1. On the `main` branch, bump the version number in `package.json` :
```sh
npm version patch -m 'Release v%s'
```
Instead of `patch` , use `minor` or `major` [as needed ](https://semver.org/ ).
Note that this produces a Git commit + tag.
1. Push the release commit and tag:
```sh
git push & & git push --tags
```
Our CI then automatically publishes the new release to npm.
