- Fix an issue with container restarts using a modified configmap or secret subpath volume mount. ([#89629](https://github.com/kubernetes/kubernetes/pull/89629), [@fatedier](https://github.com/fatedier)) [SIG Architecture, Storage and Testing]

- The list-type of the alpha `resourceClaims` field introduced to `Pods` in `1.26.0` was modified from `set` to `map`, resolving an incompatibility with use of this schema in `CustomResourceDefinitions` and with server-side apply. ([#114585](https://github.com/kubernetes/kubernetes/pull/114585), [@JoelSpeed](https://github.com/JoelSpeed))

- Fix handling of aws-load-balancer-security-groups annotation. Security-Groups assigned with this annotation are no longer modified by kubernetes which is the expected behaviour of most users. Also no unnecessary Security-Groups are created anymore if this annotation is used. ([#88691](https://github.com/kubernetes/kubernetes/pull/88691), [@Elias481](https://github.com/Elias481))...

* The protobuf serialization of API objects has been updated to store maps in a predictable order to ensure that the representation of that object does not change when saved into etcd. This prevents the same object from being seen as being modified, even when no values have changed. ([#47701](https://github.com/kubernetes/kubernetes/pull/47701), [@smarterclayton](https://github.com/smarterclayton))

- Fixes an issue in winkernel proxier that causes proxy rules to leak anytime service backends are modified. ([#112840](https://github.com/kubernetes/kubernetes/pull/112840), [@daschott](https://github.com/daschott)) [SIG Network and Windows]
