# This workflow will update apache beam master branch with next release version
# and cut release branch for current development version.

# To learn more about GitHub Actions in Apache Beam check the CI.md

# Workflow used after https://github.com/apache/beam/commit/4183e747becebd18becee5fff547af365910fc9c
# If help is needed debugging issues, you can view the cut_release_branch.sh script at that commit
# for guidance on how to do this manually.
