Release checklist

Before releasing:

• Trigger Update leaflet providers/compress JSON GitHub Action. You can do that manually from Actions tab.
• Update Changelog

Releasing:

• Make an empty release commit: git commit --allow-empty -m 'RLS: 2021.08'
• Tag the commit using an annotated tag. git tag -a 2021.08 -m "Version 2021.08"
• Push the RLS commit git push upstream main
• Also push the tag! git push upstream --tags
• Then the github worflow will create sdist/wheel, upload to PyPI, create a GitHub release, and attach the sdist
• Manually update the GitHub release body text (with content from changelog)

Packaging:

• update on conda-forge (should be done automatically once the github release is made)
• PyPI is already done by workflow
• update docs on readthedocs (trigger any build, to trigger that the new tag / version gets added)
