The main change of note in this release is the upgrade of the Loadbalancer Service (Octavia) from stable/Stein to stable/Train.
For a full list of the included changes please see upstream release notes
One of the key new features included in this release is:
Support to VIP access control list. Users can now limit incoming traffic to a set of allowed CIDRs. For details on using this feature refer to Enabling CIDR Restrictions
Some of the key areas addressed are:
Fixed a bug which prevented the creation of listeners for different protocols on the same port (i.e: tcp port 53, and udp port 53).
Fixed an issue where the listener API would accept null/None values for fields that must have a valid value.
Addressed several issues relating to the use of UDP protocols.
When a load balancer with a UDP listener is updated, the listener service is restarted, which causes an interruption of the flow of traffic during a short period of time. This issue is caused by a keepalived bug
Octavia v1 API deprecation is complete. All relevant code, tests, and docs have been removed.
