#### kube-controller-manager:
- Azure service annotation service.beta.kubernetes.io/azure-load-balancer-disable-tcp-reset has been deprecated. Its support would be removed in a future release. ([#88462](https://github.com/kubernetes/kubernetes/pull/88462), [@feiskyer](https://github.com/feiskyer)) [SIG Cloud Provider]

#### kubelet:

## Changelog since v1.23.16

## Changes by Kind

### Feature

- Kubelet TCP and HTTP probes are more effective using networking resources: conntrack entries, sockets, ... 

- GCE does not support LoadBalancer Services with ports with different protocols (TCP and UDP) ([#115966](https://github.com/kubernetes/kubernetes/pull/115966), [@aojea](https://github.com/aojea)) [SIG Apps and Cloud Provider]

- Service.beta.kubernetes.io/azure-load-balancer-disable-tcp-reset is removed.  All Standard load balancers will always enable tcp resets. ([#94297](https://github.com/kubernetes/kubernetes/pull/94297), [@MarcPow](https://github.com/MarcPow)) [SIG Cloud Provider]

*   You can once again use 0 values for conntrack min, max, max per core, tcp close wait timeout, and tcp established timeout; this functionality was broken in 1.8. ([#55261](https://github.com/kubernetes/kubernetes/pull/55261),[ @ncdc](https://github.com/ncdc))

#### **CoreDNS**

Node-local DNS cache feature is available in Alpha. This feature deploys a lightweight DNS caching Daemonset that avoids the conntrack and converts queries from UDP to more reliable TCP.
PodReady++ feature now has `kubectl` CLI support.

Progress was made towards finalizing the IPv6 dual stack support KEP and support for topological routing of services.

## Changelog since v1.24.10

## Changes by Kind

### Feature

- Kubelet TCP and HTTP probes are more effective using networking resources: conntrack entries, sockets, ... 

- Packets considered INVALID by conntrack are now dropped. In particular, this fixes
a problem where spurious retransmits in a long-running TCP connection to a service
IP could result in the connection being closed with the error "Connection reset by
peer" ([#74840](https://github.com/kubernetes/kubernetes/pull/74840), [@anfernee](https://github.com/anfernee))
