* Upgrade golang.org/x/net image to release-branch.go1.10 ([#70663](https://github.com/kubernetes/kubernetes/pull/70663), [@wenjiaswe](https://github.com/wenjiaswe))
* Fixes a bug in previous releases where a pod could be placed inside another pod's cgroup when specifying --cgroup-root ([#70678](https://github.com/kubernetes/kubernetes/pull/70678), [@dashpole](https://github.com/dashpole))

- Fixed `systemLogQuery` service name matching. ([#120678](https://github.com/kubernetes/kubernetes/pull/120678), [@rothgar](https://github.com/rothgar))
- Fixed a `1.27` scheduling regression that `PostFilter` plugin may not function if previous `PreFilter` plugins return `Skip`. ([#119769](https://github.com/kubernetes/kubernetes/pull/119769), [@Huang-Wei](https://github.com/Huang-Wei))

Fixed the bug where `spec.terminationGracePeriodSeconds` of the pod will always be overwritten by the MaxPodGracePeriodSeconds of the soft eviction, you can enable the `AllowOverwriteTerminationGracePeriodSeconds` feature gate, which will restore the previous behavior.  If you do need to set this, please file an issue with the Kubernetes project to help contributors understand why you needed it.
