# NOTE(xek): This decides the version cap of RPC messages sent to conductor

|
# and objects during rolling upgrades, when [DEFAULT]/pin_release_version
|

# 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>': {

# '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.
|
|
#
|
|
# 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.
