• Configure Codespell for checking typos via pre-commit: Configure automatic spelling check via codespell within pre-commit diffpy/diffpy.snmf#121 and use the instructions for customization provided in this PR: Add Codespell instructions in pre-commit workflow, add tips for fixing flake8 errors #171
• Add codecov coverage for each PR: Add Codecov setup to PR #177
• Add post-release checklist in issue template: Add post-release checklist for GitHub release issues template #174

Add more as needed:

We are currently experimenting whether we want to implement static type checking here: diffpy/diffpy.snmf#124. More updates to be provided based on our experience.

Also another comment for me (low priority after our packages support py 3.13) - we need to ensure our package follows PEP8 (https://peps.python.org/pep-0008/).

Some possible options:

1. Check whether pre-commit has a hook (ideal solution)
2. Add this to the github release issue checklist

Flake8 is linting for PEP8 so we are already doing that, but not applying it strictly to function/class names.

Changing variable names can break code in a non-backwards compatible way so this needs to be done carefully.

right, should have considered this aspect more when asking to change variable names for diffpy.utils, a package affecting others. Sorry about that, I will ask for your confirmation next time.

no worries. this is how code gets better....people make suggestions, code gets reviewed.....
