@alimcmaster1 can you please rebase? I think there was something wrong in master that was causing the CI to be red.

Also, do you mind editing the description with info about the changes not directly specified in the ticket. Was it required for the issue to fix the sorts in the files you removed from setup.cfg, or are they unrelated to the changes in the dependencies?
