  • Renaming published python packages

    So you have decided to rename your package, but all your continuous integration, deployment to PyPi and/or conda-forge, and automatic documentation generation with readthedocs is already set up with the old name. The obvious fear is that everything will break and lead to a big ‘ol mess, but the process is actually easier than one might think if you follow these steps …
