Note on updating your workflows

Once this PR is merged, please perform the following steps to make sure your commit hooks and workflows use the latest black version:

stash your WIP changes in the current working branch

git stash push -m "WIP on <branch-name> <short status>"

pull latest dev to get updated pre-commit hooks

• git checkout dev
• git pull upstream dev assuming you are working in a forked repo
• pip install --upgrade pip
• pip install --upgrade pre-commit

merge, install and use updated hooks on your WIP branch

• git checkout <branch-name>
• git merge dev
• pre-commit install
• git stash pop
• git add <files>
• git commit -m <message>

At this point, pre-commit hook should automatically update its dependencies to reflect your updated config file. This will usually take a few minutes.
