 ### Merging `dev` onto `release`
 Finally, if we're ready to publish a new release to PyPI and `conda`, you should create a pull request, asking to merge the `dev` branch onto the `release` branch. Again, this process is automated so that the version number gets bumped accordingly.  The only thing you need to remember is to use the proper keyword, so that our automated workflow knows how to bump the version number. Please use the following keywords:
