# Release workflow
# - When there is a push to 'main', it detects if the local version has changed and is higher than the remote (PyPI) version.
# - Generates a new nada-dsl release, signes it and pushes it to PyPI when a PR is merged that updates the version number in pyproject.toml.
# - Generates a new nada-dsl Github release
