Ticket AU-2775

Checked all the new changes, looks great!

@tikagan only note is to avoid versioning and branching with terms like final. After all, there will be future versions and other requests. You can always re-use the same polish or QA branches as well, although the PR name should be unique. I tend to do with things like:

style: miscellaneous polish or even something super ambiguous like feat: various pre-ship changes is okay. Basically we want to make sure we're as detailed as possible within the context, and sometimes, especially toward the end, that can involve some benign ambiguity (but ideally no more than we absolutely need 🙃).
