By building the whole project with `./gradlew build`, you will learn what other places need to be adjusted. Once done, create a commit using this pattern for commit message: `chore: prepare for releasing version <version>`.
 1. Once CI is green for the newly merged commits, create and push an annotated tag named `v<version>`, e. g. `v0.21.0`: `git tag -a v0.21.0 -m "chore: release version 0.21.0" && git push origin v0.21.0`. The tag should point to the commit that removes `-SNAPSHOT` from the version.
 1. On `main` branch, change version to prepare for the next development cycle, e.g. if it was `0.20.1-SNAPSHOT` before and we released it as `0.21.0`, change the version to `0.21.1-SNAPSHOT`.
 1. Ensure that the release job has succeeded.
