- Fix: remove VMSS and VMSS instances from SLB backend pool only when necessary ([#105839](https://github.com/kubernetes/kubernetes/pull/105839), [@nilo19](https://github.com/nilo19))
- Fix: skip `instance not found` when decoupling VMSSs from LB ([#105666](https://github.com/kubernetes/kubernetes/pull/105666), [@nilo19](https://github.com/nilo19))
