Checklist

Note: If any of the items in the checklist are not relevant to your PR, just check the box.

For any Pull Request

Is the following correct:

• the title of the Pull Request?
• the title of the corresponding issue?
• there are no other open Pull Requests for the same update/change?
• that the issue which this Pull Request fixes ("Fixes...") is mentioned?

When Changes Were Made

Did you:

• update the changelog?
• update the cookiecutter-template?
• update the implementation?
• check coverage and add tests: unit tests and, if relevant, integration tests?
• update the User Guide & other documentation?
• resolve any failing CI criteria (incl. Sonar quality gate)?

When Preparing a Release

Have you:

• thought about version number (major, minor, patch)?
• checked Exasol packages for updates and resolved open vulnerabilities, if easily possible?

[ArBridgeman]

If a project is not ready for this, they can remove the job with the .workflow-patcher.yml.

By adding a comment at the top of workflows maintained by the PTB, we make it clearer what is maintained vs not by us. Additionally, by adding when it was last updated, it gives the projects using the PTB a direct idea of when this was last touched before checking the git blame. [The PTB currently lacks a mechanism to say when a workflow was removed or not, but this comment could give an important hint. It also encourages user to NOT modify the .yml files but let the PTB maintain them.]

compare the generated workflows against the files in .github/workflows

This I don't understand, I thought the generated workflows would be in .github/workflows

maybe: compare the workflows that would be generated against ...

[ArBridgeman]

Ah, we compare the string content of the generated workflows to the existing files. Yeah, that could be better worded 😅 I updated the text so hopefully it's a bit clearer 😊
