grafana/.github/workflows/release-comms.yml

# This workflow runs whenever the release PR is merged. It includes post-release communication processes like
# posting to slack, the website, community forums, etc.
# Only things that happen after a release is completed and all of the necessary code changes (like the changelog) are made.
