API version history:

1.0 - Initial version.
|
|
1.1 - Changed methods to accept backup objects instead of IDs.
|
|
1.2 - A version that got in by mistake (without breaking anything).
|
|
1.3 - Dummy version bump to mark start of having cinder-backup service
|
|
decoupled from cinder-volume.
|
|
|
|
... Mitaka supports messaging 1.3. Any changes to existing methods in
|
|
1.x after this point should be done so that they can handle version cap
|
|
set to 1.3.
|
|
|
|
2.0 - Remove 1.x compatibility
|
|
2.1 - Adds set_log_levels and get_log_levels
|
|
2.2 - Adds publish_service_capabilities
