@cjlynch278 It looks like there may have been accidental changes to logic (there are some test failures). You'll also want to run black to fix linting.

Hi @cjlynch278

Workflow here should be:

• update black to new version
• run black on files
• for the lines that have changed, try removing trailing commas
• run black on files again
• downgrade black to current version, check nothing changes

Hi @cjlynch278 - is this still active?
