Reminders

• Make sure that your code follows our style. Use the other functions/files as a basis.
• Add tests for new features or tests that would have caught the bug that you're fixing.
• Describe changes to function behavior and arguments in a comment below the function declaration.
• If adding new functionality, add a detailed description to the documentation and/or an example.

Nothing against updating the workflow but honestly I don't see the interest on these frequent updates of the SCM that cause test breakings.

I agree. I think we should be reminded that a new SCM is available, then we can decide if we want to update the CPTs or not.
