- Fix: ignore not a VMSS error for VMAS nodes in EnsureBackendPoolDeleted. (#105185, @ialidzhikov) [SIG Cloud Provider]
- Fix: leave the probe path empty for TCP probes (#105253, @nilo19) [SIG Cloud Provider]
- Fix: remove VMSS and VMSS instances from SLB backend pool only when necessary (#105839, @nilo19) [SIG Cloud Provider]
- Fix: skip instance not found when decoupling vmss from lb (#105666, @nilo19) [SIG Cloud Provider]

* fix race condition when attach azure disk in vmss ([#71992](https://github.com/kubernetes/kubernetes/pull/71992), [@andyzhangx](https://github.com/andyzhangx))

## Changelog since v1.13.11

### Other notable changes

* Fix aggressive VM calls for Azure VMSS ([#83102](https://github.com/kubernetes/kubernetes/pull/83102), [@feiskyer](https://github.com/feiskyer))

- Azure virtual machine scale sets (VMSS) allow you to create and manage identical load balanced VMs that automatically increase or decrease based on demand or a set schedule.

These must provide `msgp` serialization and deserialization.

In the examples we use a `MSS` type, which is a `map[string]string` that is `msgp` serializable.
