- Kube-apiserver: redirect responses are no longer returned from backends by default. Set `--aggregator-reject-forwarding-redirect=false` to continue forwarding redirect responses. ([#112358](https://github.com/kubernetes/kubernetes/pull/112358), [@enj](https://github.com/enj)) [SIG API Machinery]

- Fix: set nil cache entry based on old cache ([#87591](https://github.com/kubernetes/kubernetes/pull/87591), [@aramase](https://github.com/aramase)) [SIG Cloud Provider]

The default pkg-config tool may be changed by setting the PKG_CONFIG environment variable.

For security reasons, only a limited set of flags are allowed, notably -D, -U, -I, and -l.
To allow additional flags, set CGO_CFLAGS_ALLOW to a regular expression
matching the new flags. To disallow flags that would otherwise be allowed,
set CGO_CFLAGS_DISALLOW to a regular expression matching arguments
that must be disallowed. In both cases the regular expression must match

 - Kubeadm respects resolvConf value set by user even if systemd-resolved service is active. kubeadm no longer sets the flag in '--resolv-conf' in /var/lib/kubelet/kubeadm-flags.env. If you have this flag in /var/lib/kubelet/kubeadm-flags.env or /etc/default/kubelet (/etc/sysconfig/kubelet for RPMs) please remove it and set the value using KubeletConfiguration ([#90394](https://github.com/kubernetes/kubernetes/pull/90394), [@Sa...

Besides the above new features, support for Azure Virtual Machine Scale Sets (VMSS) and Cluster-Autoscaler is now stable and considered GA:

- 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.
