They are stored in the project already: https://github.com/hibernate/hibernate-ogm/tree/master/src/main/release-scripts

The one for the release notes is https://github.com/hibernate/hibernate-ogm/blob/master/src/main/release-scripts/pre-release.rb

The other scripts in that folder resemble the steps from the release job on CI, we only did not yet get to changing the job to invoking these scripts instead of the inline bash steps.
