Releasing
=========

1. Update `CHANGELOG.md`.

2. Set versions:

    ```
    export RELEASE_VERSION=X.Y.Z
    export NEXT_VERSION=X.Y.Z-SNAPSHOT
    ```

3. Update versions, tag the release, and prepare for the next release.

    ```
    sed -i "" \
      "s/version = \".*\"/version = \"$RELEASE_VERSION\"/g" \
      build.gradle.kts
    sed -i "" \
