## Changelog since v1.22.0-alpha.1
## Urgent Upgrade Notes
### (No, really, you MUST read this before you upgrade)
- Intree volume plugin scaleio support is been completely removed from Kubernetes. ([#101685](https://github.com/kubernetes/kubernetes/pull/101685), [@Jiawei0227](https://github.com/Jiawei0227)) [SIG API Machinery, Node and Storage]
- Newly provisioned PVs by Azure disk will no longer have the beta FailureDomain label. Azure disk volume plugin will start to have GA topology label instead. ([#101534](https://github.com/kubernetes/kubernetes/pull/101534), [@kassarl](https://github.com/kassarl)) [SIG Cloud Provider and Storage]
- Scheduler's CycleState now embeds internal read/write locking inside its Read() and Write() functions. Meanwhile, Lock() and Unlock() function are removed.
scheduler plugin developers are now required to remove CycleState#Lock() and CycleState#Unlock(). Just simply use Read() and Write() as they're natively thread-safe now. ([#101542](https://github.com/kubernetes/kubernetes/pull/101542), [@Huang-Wei](https://github.com/Huang-Wei)) [SIG Scheduling and Storage]
## Changes by Kind
### Deprecation
- Controller-manager: the following flags have no effect and would be removed in v1.24:
- `--port`
- `--address`
The insecure port flags `--port` may only be set to 0 now.
In addtion, please be careful that:
- controller-manager MUST start with `--authorization-kubeconfig` and `--authentication-kubeconfig` correctly set to get authentication/authorization working.
- liveness/readiness probes to controller-manager MUST use HTTPS now, and the default port has been changed to 10257.
- Applications that fetch metrics from controller-manager should use a dedicated service account which is allowed to access nonResourceURLs `/metrics`. ([#96216](https://github.com/kubernetes/kubernetes/pull/96216), [@knight42](https://github.com/knight42)) [SIG API Machinery, Cloud Provider, Instrumentation and Testing]
- Ingress v1beta1 has been deprecated ([#102030](https://github.com/kubernetes/kubernetes/pull/102030), [@aojea](https://github.com/aojea)) [SIG CLI, Network and Testing]
- Kubead: remove the deprecated "--csr-only" and "--csr-dir" flags from "kubeadm init phase certs". Deprecate the same flags under "kubeadm certs renew". In both cases the command "kubeadm certs generate-csr" should be used instead. ([#102108](https://github.com/kubernetes/kubernetes/pull/102108), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
- Kubeadm: remove the ClusterStatus API from v1beta3 and its management in the kube-system/kubeadm-config ConfigMap. This method of keeping track of what API endpoints exists in the cluster was replaced (in a prior release) by a method to annotate the etcd Pods that kubeadm creates in "stacked etcd" clusters. The following CLI sub-phases are deprecated and are now a NO-OP: for " kubeadm join": "control-plane-join/update-status", for "kubeadm reset": "update-cluster-status". Unless you are using these phases explicitly, you should not be affected. ([#101915](https://github.com/kubernetes/kubernetes/pull/101915), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
- Kubeadm: remove the deprecated command "kubeadm alpha kubeconfig". Please use "kubeadm kubeconfig" instead. ([#101938](https://github.com/kubernetes/kubernetes/pull/101938), [@knight42](https://github.com/knight42)) [SIG Cluster Lifecycle]
- Kubeadm: remove the deprecated command 'kubeadm config view'. A replacement for this command is 'kubectl get cm -n kube-system kubeadm-config -o=jsonpath="{.data.ClusterConfiguration}"' ([#102071](https://github.com/kubernetes/kubernetes/pull/102071), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
- Kubeadm: remove the deprecated flag '--image-pull-timeout' for 'kubeadm upgrade apply' command ([#102093](https://github.com/kubernetes/kubernetes/pull/102093), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]
- Kubeadm: remove the deprecated flag --insecure-port from the kube-apiserver manifest that kubeadm manages. The flag had no effect since 1.20, since the insecure serving of the component was disabled in the same version. ([#102121](https://github.com/kubernetes/kubernetes/pull/102121), [@pacoxu](https://github.com/pacoxu)) [SIG Cluster Lifecycle]
- Kubeadm: remove the deprecated hyperkube image support in v1beta3. This implies removal of ClusterConfiguration.UseHyperKubeImage. ([#101537](https://github.com/kubernetes/kubernetes/pull/101537), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
- Kubeadm: remove the field ClusterConfiguration.DNS.Type in v1beta3 since CoreDNS is the only supported DNS type. ([#101547](https://github.com/kubernetes/kubernetes/pull/101547), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
- `storageos`,`quobyte` and `flocker` storage volume plugins are deprecated and will be removed in a later release. ([#101773](https://github.com/kubernetes/kubernetes/pull/101773), [@Jiawei0227](https://github.com/Jiawei0227)) [SIG Storage]
### API Change
- Add alpha support for HostProcess containers on Windows ([#99576](https://github.com/kubernetes/kubernetes/pull/99576), [@marosset](https://github.com/marosset)) [SIG API Machinery, Apps, Node, Testing and Windows]
- Add three metrics to job controller to monitor if Job works in a healthy condition.
IndexedJob promoted to Beta ([#101292](https://github.com/kubernetes/kubernetes/pull/101292), [@AliceZhang2016](https://github.com/AliceZhang2016)) [SIG Apps, Instrumentation and Testing]
- Corrected the documentation for escaping dollar signs in a container's env, command and args property. ([#101916](https://github.com/kubernetes/kubernetes/pull/101916), [@MartinKanters](https://github.com/MartinKanters)) [SIG Apps]
- Omit comparison with boolean constant ([#101523](https://github.com/kubernetes/kubernetes/pull/101523), [@GreenApple10](https://github.com/GreenApple10)) [SIG CLI and Cloud Provider]
- Pod Affinity NamespaceSelector and the associated CrossNamespaceAffinity quota scope graduated to beta ([#101496](https://github.com/kubernetes/kubernetes/pull/101496), [@ahg-g](https://github.com/ahg-g)) [SIG API Machinery, Apps and Testing]
- V1.Node .status.images[].names is now optional ([#102159](https://github.com/kubernetes/kubernetes/pull/102159), [@roycaihw](https://github.com/roycaihw)) [SIG Apps and Node]
### Feature
- Added BinaryData description to kubectl describe ([#100568](https://github.com/kubernetes/kubernetes/pull/100568), [@lauchokyip](https://github.com/lauchokyip)) [SIG CLI]
- Feat: change parittion style to GPT on Windows ([#101412](https://github.com/kubernetes/kubernetes/pull/101412), [@andyzhangx](https://github.com/andyzhangx)) [SIG Storage and Windows]
- Improve logging of APIService availability changes in kube-apiserver. ([#101420](https://github.com/kubernetes/kubernetes/pull/101420), [@sttts](https://github.com/sttts)) [SIG API Machinery]
- Kubeadm: add the RootlessControlPlane kubeadm specific feature gate (Alpha in 1.22, disabled by default).
It can be used to enable an experimental feature that makes the control plane component static Pod containers
for kube-apiserver, kube-controller-manager, kube-scheduler and etcd to run as a non-root users. ([#102158](https://github.com/kubernetes/kubernetes/pull/102158), [@vinayakankugoyal](https://github.com/vinayakankugoyal)) [SIG Cluster Lifecycle]
- Kubeadm: set the seccompProfile to runtime/default in the PodSecurityContext of the control-plane components that run as static Pods. ([#100234](https://github.com/kubernetes/kubernetes/pull/100234), [@vinayakankugoyal](https://github.com/vinayakankugoyal)) [SIG Cluster Lifecycle]
- Kubernetes is now built with Golang 1.16.4 ([#101809](https://github.com/kubernetes/kubernetes/pull/101809), [@justaugustus](https://github.com/justaugustus)) [SIG Cloud Provider, Instrumentation, Release and Testing]
- Metrics server nanny has now poll period set to 30s (previously 5 minutes) to allow faster scaling of metrics server. ([#101869](https://github.com/kubernetes/kubernetes/pull/101869), [@olagacek](https://github.com/olagacek)) [SIG Cloud Provider and Instrumentation]
- New metrics: `apiserver_kube_aggregator_x509_missing_san_total` and `apiserver_webhooks_x509_missing_san_total`. This metric measures a number of connections to webhooks/aggregated API servers that use certificates without Subject Alternative Names. It being non-zero is a warning sign that these connections will stop functioning in the future since Golang is going to deprecate x509 certificate subject Common Names for server hostname verification. ([#95396](https://github.com/kubernetes/kubernetes/pull/95396), [@stlaz](https://github.com/stlaz)) [SIG API Machinery, Auth and Instrumentation]
- Node Problem Detector is now available for GCE Windows nodes. ([#101539](https://github.com/kubernetes/kubernetes/pull/101539), [@jeremyje](https://github.com/jeremyje)) [SIG Cloud Provider, Node and Windows]
- Secret values are now masked by default in kubectl diff output. ([#96084](https://github.com/kubernetes/kubernetes/pull/96084), [@loozhengyuan](https://github.com/loozhengyuan)) [SIG CLI]
- The `WarningHeader` feature is now GA and is unconditionally enabled. The `apiserver_requested_deprecated_apis` metric has graduated to stable status. The `WarningHeader` feature-gate is no longer operative and will be removed in v1.24. ([#100754](https://github.com/kubernetes/kubernetes/pull/100754), [@liggitt](https://github.com/liggitt)) [SIG API Machinery, Instrumentation and Testing]
- Warnings for use of deprecated and known-bad values in pod specs are now sent ([#101688](https://github.com/kubernetes/kubernetes/pull/101688), [@liggitt](https://github.com/liggitt)) [SIG API Machinery and Auth]
- You can use this Builder function to create events Field Selector ([#101817](https://github.com/kubernetes/kubernetes/pull/101817), [@cndoit18](https://github.com/cndoit18)) [SIG API Machinery and Scalability]
