# Lists all remote tags on the upstream, which gives tags in format:
# "<commit> ref/tags/<tag>". Strips commit + tag prefix, filters out tags for v1+,
# and manually removes v1.2.0-alpha.1, since that version's manifest contains
# duplicate CRD resources (2 CRDs with the same name) which causes problems
# with the versionchecker test.
#
# This file has a version suffix so we can force all checkouts to pick up the new
# version in response to a change in how we generate it. Users will get warning messages
# printing explaining the latest version available in their checkout when they run tests,
# but sometimes we'll want to force a new version.
