# This script is supposed to be used to prepare a release branch based on master.
4+
# The script performs the following steps:
5+
# - Create a release branch in SBO repository
6+
# - Add a label to the SBO repository to be used to mark PRs to be cherry-picked in the release branch
7+
# - Prepare a PR branch for openshift/release repository adding OpenShift CI jobs for running acceptance and performance tests on PRs to the release branch
8+
# - Bump docs version in the release branch
9+
# - (TODO: Add a GitHub Action job for cherry-picking in the release branch)
