# This job can be started by a git tag or using the workflow dispatch.

# The version string *must* be of the format: vYY.MM(-alphaN|-betaN|-rcN)
#
# In /etc/os-release this string is used for VERSION, VERSION_ID, and
# IMAGE_VERSION, with the 'v' prefix.  In release artifact filenames,
# and zip file directory names, the 'v' is dropped per convention.
