+## Changelog since v1.25.0
+
+## Urgent Upgrade Notes
+
+### (No, really, you MUST read this before you upgrade)
+
+ - Deprecated beta APIs scheduled for removal in 1.26 are no longer served. See https://kubernetes.io/docs/reference/using-api/deprecation-guide/#v1-26 for more information. ([#111973](https://github.com/kubernetes/kubernetes/pull/111973), [@liggitt](https://github.com/liggitt)) [SIG API Machinery]
+ 
+## Changes by Kind
+
+### Deprecation
+
+- The `gcp` and `azure` auth plugins have been removed from client-go and kubectl. See https://github.com/Azure/kubelogin and https://cloud.google.com/blog/products/containers-kubernetes/kubectl-auth-changes-in-gke for details about the cloud-specific replacements. ([#112341](https://github.com/kubernetes/kubernetes/pull/112341), [@enj](https://github.com/enj)) [SIG API Machinery and Auth]
+
+### API Change
+
+- Add auth API to get self subject attributes (new selfsubjectreviews API is added). 
+  The corresponding command for kubctl is provided - `kubectl auth whoami`. ([#111333](https://github.com/kubernetes/kubernetes/pull/111333), [@nabokihms](https://github.com/nabokihms)) [SIG API Machinery, Auth, CLI and Testing]
+- Clarified the CFS quota as 100ms in the code comments and set the minimum cpuCFSQuotaPeriod to 1ms to match Linux kernel expectations. ([#112123](https://github.com/kubernetes/kubernetes/pull/112123), [@paskal](https://github.com/paskal)) [SIG API Machinery and Node]
+- Component-base: make the validation logic about LeaderElectionConfiguration consistent between component-base and client-go ([#111758](https://github.com/kubernetes/kubernetes/pull/111758), [@SataQiu](https://github.com/SataQiu)) [SIG API Machinery and Scheduling]
+- Fixes spurious `field is immutable` errors validating updates to Event API objects via the `events.k8s.io/v1` API ([#112183](https://github.com/kubernetes/kubernetes/pull/112183), [@liggitt](https://github.com/liggitt)) [SIG Apps]
+- Protobuf serialization of metav1.MicroTime timestamps (used in `Lease` and `Event` API objects) has been corrected to truncate to microsecond precision, to match the documented behavior and JSON/YAML serialization. Any existing persisted data is truncated to microsecond when read from etcd. ([#111936](https://github.com/kubernetes/kubernetes/pull/111936), [@haoruan](https://github.com/haoruan)) [SIG API Machinery]
+- Revert regression that prevented client-go latency metrics to be reported with a template URL to avoid label cardinality. ([#111752](https://github.com/kubernetes/kubernetes/pull/111752), [@aanm](https://github.com/aanm)) [SIG API Machinery]
+- [kubelet] Change default `cpuCFSQuotaPeriod` value with enabled `cpuCFSQuotaPeriod` flag from 100ms to 100µs to match the Linux CFS and k8s defaults. `cpuCFSQuotaPeriod` of 100ms now requires `customCPUCFSQuotaPeriod` flag to be set to work. ([#111520](https://github.com/kubernetes/kubernetes/pull/111520), [@paskal](https://github.com/paskal)) [SIG API Machinery and Node]
+
+### Feature
+
+- A new "DisableCompression" field (default = false) has been added to kubeconfig under cluster info. When set to true, clients using the kubeconfig opt out of response compression for all requests to the apiserver. This can help improve list call latencies significantly when client-server network bandwidth is ample (>30MB/s) or if the server is CPU-constrained. ([#112309](https://github.com/kubernetes/kubernetes/pull/112309), [@shyamjvs](https://github.com/shyamjvs)) [SIG API Machinery and Auth]
+- API Server tracing root span name for opentelemetry is changed from "KubernetesAPI" to "HTTP GET" ([#112545](https://github.com/kubernetes/kubernetes/pull/112545), [@dims](https://github.com/dims)) [SIG API Machinery, Architecture, Auth, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Node, Storage and Testing]
+- Add new Golang runtime-related metrics to Kubernetes components:
+  - go_gc_cycles_automatic_gc_cycles_total
+  - go_gc_cycles_forced_gc_cycles_total
+  - go_gc_cycles_total_gc_cycles_total

+- CSRDuration feature gate that graduated to GA in 1.24 and was unconditionally enabled has been removed in v1.26 ([#112386](https://github.com/kubernetes/kubernetes/pull/112386), [@Shubham82](https://github.com/Shubham82)) [SIG Auth]
+- Client-go: SharedInformerFactory supports waiting for goroutines during shutdown ([#112200](https://github.com/kubernetes/kubernetes/pull/112200), [@pohly](https://github.com/pohly)) [SIG API Machinery]
+- Kube-apiserver: gzip compression switched from level 4 to level 1 to improve large list call latencies in exchange for higher network bandwidth usage (10-50% higher). This increases the headroom before very large unpaged list calls exceed request timeout limits. ([#112299](https://github.com/kubernetes/kubernetes/pull/112299), [@shyamjvs](https://github.com/shyamjvs)) [SIG API Machinery]
+- Kubeadm: "show-join-command" has been added as a new separate phase at the end of "kubeadm init". You can skip printing the join information by using "kubeadm init --skip-phases=show-join-command". Executing only this phase on demand will throw an error because the phase needs dependencies such as bootstrap tokens to be pre-populated. ([#111512](https://github.com/kubernetes/kubernetes/pull/111512), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]
+- Kubeadm: add the flag "--cleanup-tmp-dir" for "kubeadm reset". It will cleanup the contents of "/etc/kubernetes/tmp". The flag is off by default. ([#112172](https://github.com/kubernetes/kubernetes/pull/112172), [@chendave](https://github.com/chendave)) [SIG Cluster Lifecycle]
+- Kubeadm: try to load CA cert from external CertificateAuthority file when CertificateAuthorityData is empty for existing kubeconfig ([#111783](https://github.com/kubernetes/kubernetes/pull/111783), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]

+- The `goroutines` metric is newly added in the scheduler. 
+  It replaces `scheduler_goroutines` metric and it counts the number of goroutine in more places than `scheduler_goroutine` does. ([#112003](https://github.com/kubernetes/kubernetes/pull/112003), [@sanposhiho](https://github.com/sanposhiho)) [SIG Instrumentation and Scheduling]

The rate limit is based on 1/2 of the timeout configured, with no burst allowed. ([#112046](https://github.com/kubernetes/kubernetes/pull/112046), [@aojea](https://github.com/aojea)) [SIG API Machinery]

+- Fix race condition in GCE between containerized mounter setup in the kubelet and node startup. ([#112195](https://github.com/kubernetes/kubernetes/pull/112195), [@mattcary](https://github.com/mattcary)) [SIG Cloud Provider and Storage]
+- Fix relative cpu priority for pods where containers explicitly request zero cpu by giving the lowest priority instead of falling back to the cpu limit to avoid possible cpu starvation of other pods ([#108832](https://github.com/kubernetes/kubernetes/pull/108832), [@waynepeking348](https://github.com/waynepeking348)) [SIG Node]

+- For raw block CSI volumes on Kubernetes, kubelet was incorrectly calling CSI NodeStageVolume for every single "map" (i.e. raw block "mount") operation for a volume already attached to the node. This PR ensures it is only called once per volume per node. ([#112403](https://github.com/kubernetes/kubernetes/pull/112403), [@akankshakumari393](https://github.com/akankshakumari393)) [SIG Storage]

+- Kube-apiserver: x-kubernetes-list-type validation is now enforced when updating status of custom resources ([#111866](https://github.com/kubernetes/kubernetes/pull/111866), [@pacoxu](https://github.com/pacoxu)) [SIG API Machinery]

+- Log messages and metrics for the watch cache are now keyed by `<resource>.<group>` instead of `go` struct type. This means e.g. that `*v1.Pod` becomes `pods`. Additionally, resources that come from CustomResourceDefinitions are now displayed as the correct resource and group, instead of `*unstructured.Unstructured`. ([#111807](https://github.com/kubernetes/kubernetes/pull/111807), [@ncdc](https://github.com/ncdc)) [SIG API Machinery and Instrumentation]

+### Other (Cleanup or Flake)
+
+- E2e: tests can now register callbacks with ginkgo.BeforeEach/AfterEach/DeferCleanup directly after creating a framework instance and are guaranteed that their code is called after the framework is initialized and before it gets cleaned up. ginkgo.DeferCleanup replaces f.AddAfterEach and AddCleanupAction which got removed to simplify the framework.

+- Kubeadm: remove the toleration for the "node-role.kubernetes.io/master" taint from the CoreDNS deployment of kubeadm. With the 1.25 release of kubeadm the taint "node-role.kubernetes.io/master" is no longer applied to control plane nodes and the toleration for it can be removed with the release of 1.26. You can also perform the same toleration removal from your own addon manifests.
