- Kubernetes 1.24 bumped version of golang it is compiled with to go1.18, which introduced significant changes to its garbage collection algorithm. As a result, we observed an increase in memory usage for kube-apiserver in larger an heavily loaded clusters up to ~25% (with the benefit of API call latencies drop by up to 10x on 99th percentiles). If the memory increase is not acceptable for you you can mitigate by setting...

* Pass cluster_location argument to Heapster ([#65176](https://github.com/kubernetes/kubernetes/pull/65176), [@kawych](https://github.com/kawych))
* fixes a memory leak in the kube-controller-manager observed when large numbers of pods with tolerations are created/deleted ([#65339](https://github.com/kubernetes/kubernetes/pull/65339), [@liggitt](https://github.com/liggitt))

* Prevents a `kubectl delete` hang when deleting controller managed lists ([#65367](https://github.com/kubernetes/kubernetes/pull/65367), [@deads2k](https://github.com/deads2k))

- Fixed a bug that resulted in "grpc: the client connection is closing" errors shortly after the Kubernetes API server automatically reloaded its encryption-at-rest config due to an observed change to the file.  This bug was only encountered when the --encryption-provider-config-automatic-reload flag was set to true.

- Added a feature to report an event about a Pod if kubelet observes a failed attach operation, even if the kubelet is running with `--enable-controller-attach-detach=false`. ([#124884](https://github.com/kubernetes/kubernetes/pull/124884), [@carlory](https://github.com/carlory))
