## Urgent Upgrade Notes 

### (No, really, you MUST read this before you upgrade)

- 'The `IPv6DualStack` feature gate for external cloud providers was removed.
  (The feature became GA in 1.23 and the gate was removed for all other
  components several releases ago.) If you were still manually

  // externalName is the external reference that discovery mechanisms will
  // return as an alias for this service (e.g. a DNS CNAME record). No
  // proxying will be involved.  Must be a lowercase RFC-1123 hostname
  // (https://tools.ietf.org/html/rfc1123) and requires `type` to be "ExternalName".
  // +optional
  optional string externalName = 10;

Server, is resolved in v1.13.0 (and in [v1.10.11](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/CHANGELOG-1.10.md/#v11011), [v1.11.5](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/CHANGELOG-1.11.md/#v1115), and [v1.12.3](https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/CHANGELOG-1.12.md/#v1123)). We recommend all clusters running previous versions update to one of these releases immediately. See issue [#71411](https://github.com/kubernetes/kubernetes/issues/71411)...

- Kubelet now cleans up the Node's cloud node IP annotation correctly if you
  stop using `--node-ip`. (In particular, this fixes the problem where people who
  were unnecessarily using `--node-ip` with an external cloud provider in 1.23,
  and then running into problems with 1.24, could not fix the problem by just
  removing the unnecessary `--node-ip` from the kubelet arguments, because

  The in-tree AzureFile plugin "kubernetes.io/azure-file" is now deprecated and will be removed in 1.23. Users should enable CSIMigration + CSIMigrationAzureFile features and install the AzureFile CSI Driver (https://github.com/kubernetes-sigs/azurefile-csi-driver) to avoid disruption to existing Pod and PVC objects at that time.
