• Have you run git fetch and pulled the latest changes from the branch you're basing your PR against? Will do, based on review.
• If you're adding new classes, have you added them to classes_def.xml in the relevant directory?
• Have you added a checksum in classes_def.xml to any and all new classes you're implementing, and rebuilt?
• If you're updating classes, have you incremented the ClassVersion by one compared to develop in classes_def.xml?
