# This script helps with updating versions across the repo, updating the
# multiple places where we encode a aws-load-balancer-controller version number.

# Use: hack/set-version <new-release-version>

# new-release-version is the version you are releasing.

#
# Examples:
# 1.20.1
# 1.21.0-alpha.1
# 1.21.0-beta.1
