Release Process

1. Checkout the current master branch, with a clean working directory.

2. Modify the CHANGELOG.rst to include changes made since the last release.

3. Bump the version in packaging/__about__.py

4. Install the latest setuptools, wheel and twine packages from PyPI:

   $ pip install --upgrade setuptools wheel twine
   

5. Ensure no dist/ folder exists and then create the distribution files:

   $ python setup.py sdist bdist_wheel
   

6. Check the built distribution files with twine:

   $ twine check dist/*
   

7. If all goes well, upload the build distribution files:

   $ twine upload dist/*
   

8. Bump the version for development in packaging/__about__.py and CHANGELOG.rst.
