### RELEASING OPERATOR-LIB
# Every operator-lib release should have a corresponding git semantic version tag
# begining with `v`, ex.n `v1.2.3`.
#
# STEP 1: Create a release branch with the name vX.Y.x. Example: git checkout -b v1.2.x
#
# STEP 2: Run the release script by providing the operator-lib release version as an argument
# in the above mentioned format. Example: ./release vX.Y.Z
#
# STEP 3: This script will create a release tag locally. Push the release branch and tag:
# git push upstream <release-branch>
# git push upstream <tag-name>, wherein <tag-name> is the release version.
#
# STEP 4: Update the release notes in github with the changes included in corresponding
# operator-lib version.
