# NOTE(xek): This decides the version cap of RPC messages sent to conductor
# and objects during rolling upgrades, when [DEFAULT]/pin_release_version
# configuration is set.
#
# Remember to add a new entry for the new version that is shipping in a new
# release.
#
# We support a rolling upgrade between adjacent named releases, as well as
# between a release and master, so old, unsupported releases can be removed,
# together with the supporting code, which is typically found in an object's
# make_compatible methods and RPC client code.
# NOTE(xek): The format of this dict is:
# { '<release version>': {
# 'api': '<Bare Metal API version>',
# 'rpc': '<RPC API version>',
# 'objects': {
# '<object class name>': ['<object version>'],
# }
# },
# }
# The list should contain all objects which are persisted in the database and
# sent over RPC. Notifications/Payloads are not being included here since we
# don't need to pin them during rolling upgrades.
#
# For each object, the versions of that object are listed from latest version
# to oldest version. This is a list since an object could be in more than one
# version in a particular release.
# NOTE(rloo): We need a list, not just the latest version, for the DB queries
# that filter for objects that are not in particular versions; for more info,
# see comments after L1128 of
# https://review.openstack.org/#/c/408556/52/ironic/db/sqlalchemy/api.py.
#
# There should always be a 'master' entry that reflects the objects in the
# master branch.
#
# Just before doing a release, copy the 'master' entry, and rename the first
# 'master' entry to the (semver) version being released.
#
# Just after doing a named release, delete any entries associated with the
# oldest named release.
