@ParseThis This PR came in just before we added a PR template with further instructions. I edited your comment into the new PR template. There are a few housekeeping items left. You mention that this is a WIP - is there more to do other than the changelog and AUTHORS.md? |

@pganssle Nothing else, since its my first PR I wanted to sure of the standard here. Thanks for editing the comments! Everything else you mentioned makes sense and will be added. |
