# Branches $SOURCE_BRANCH,develop, rc, master must exist and be up to date.
# This script must be run from $SOURCE_BRANCH.
# Before running this script edit create_release_properties.sh
# Description:
# 1. create temporary release branch with name release/$RELEASE_VERSION
# 2. bump version to $RELEASE_VERSION
# 3. commit to release branch, then merge it into master
# 4. merge release into rc, with expected rc version (only if releasing from hotfix)
# 5. merge release (with changes to rc) into develop, with expected develop version
# 6. delete temporary release branch
# 7. create hotfix branch from master
