Release to PyPI

To release a new version of django-simple-bulma to PyPI, all you have to do is the following:

• Bump the version in setup.py.
• Publish a corresponding release on GitHub.

In this release, please include as much information as you can on what the release contains.

We should also bump Bulma and submodules to the latest version whenever we do minor releases.

To do this, you have to execute two commands in the git repo:

git submodule update --init --recursive    # Only for first-time setup.
git submodule update --recursive --remote  # To actually do the update.

This will update Bulma and all the extensions to the latest stable version.
