• Update CHANGELOG.rst for each commit separately:
  • Pay attention to write entries under the "Unreleased" section.
  • Mark all breaking changes as "BACKWARD INCOMPATIBLE:" and put them
    before non-breaking changes.
  • If a commit modifies a feature listed under "Unreleased" section,
    it might be sufficient to modify the existing CHANGELOG entry from previous
    commit(s).
• Bump the process version:
  • MAJOR version (first number): Backward incompatible changes (changes
    that break the api/interface). Examples: renaming the input/output, adding
    mandatory input, removing input/output...
  • MINOR version (middle number): add functionality or changes in a
    backwards-compatible manner. Examples: add output field, add non-mandatory
    input parameter, use a different tool that produces same results...
  • PATCH version (last number): changes/bug fixes that do not affect
    the api/interface. Examples: typo fix, change/add warning messages...
• All inputs are used in process.
• All output fields have a value assigned to them.

When this is deployed make sure to validate that the prefetch messages and errors are getting printed to stdout. The tests do not cover that because it takes too long to fetch data.
