- Images for cloud-controller-manager, kube-apiserver, kube-controller-manager, and kube-scheduler now contain a minimal /etc/nsswitch.conf and should respect /etc/hosts for lookups ([#69238](https://github.com/kubernetes/kubernetes/pull/69238), [@BenTheElder](https://github.com/BenTheElder))

- Changed Job controller to use the controller UID index for Pod lookups to improve performance. ([#132305](https://github.com/kubernetes/kubernetes/pull/132305), [@xigang](https://github.com/xigang))

- Hostnames are now converted to lowercase before being used for node lookups in the kubernetes-worker charm. ([#65487](https://github.com/kubernetes/kubernetes/pull/65487), [@dshcherb](https://github.com/dshcherb))
