## Changelog since v1.21.0-alpha.3
## Urgent Upgrade Notes
### (No, really, you MUST read this before you upgrade)
- The metric `storage_operation_errors_total` is not removed, but is marked deprecated, and the metric `storage_operation_status_count` is marked deprecated. In both cases the storage_operation_duration_seconds metric can be used to recover equivalent counts (using `status=fail-unknown` in the case of `storage_operations_errors_total`). ([#99045](https://github.com/kubernetes/kubernetes/pull/99045), [@mattcary](https://github.com/mattcary)) [SIG Instrumentation and Storage]
## Changes by Kind
### Deprecation
- The `batch/v2alpha1` CronJob type definitions and clients are deprecated and removed. ([#96987](https://github.com/kubernetes/kubernetes/pull/96987), [@soltysh](https://github.com/soltysh)) [SIG API Machinery, Apps, CLI and Testing]
### API Change
- Cluster admins can now turn off /debug/pprof and /debug/flags/v endpoint in kubelet by setting enableProfilingHandler and enableDebugFlagsHandler to false in their kubelet configuration file. enableProfilingHandler and enableDebugFlagsHandler can be set to true only when enableDebuggingHandlers is also set to true. ([#98458](https://github.com/kubernetes/kubernetes/pull/98458), [@SaranBalaji90](https://github.com/SaranBalaji90)) [SIG Node]
- The BoundServiceAccountTokenVolume feature has been promoted to beta, and enabled by default.
- This changes the tokens provided to containers at `/var/run/secrets/kubernetes.io/serviceaccount/token` to be time-limited, auto-refreshed, and invalidated when the containing pod is deleted.
- Clients should reload the token from disk periodically (once per minute is recommended) to ensure they continue to use a valid token. `k8s.io/client-go` version v11.0.0+ and v0.15.0+ reload tokens automatically.
- By default, injected tokens are given an extended lifetime so they remain valid even after a new refreshed token is provided. The metric `serviceaccount_stale_tokens_total` can be used to monitor for workloads that are depending on the extended lifetime and are continuing to use tokens even after a refreshed token is provided to the container. If that metric indicates no existing workloads are depending on extended lifetimes, injected token lifetime can be shortened to 1 hour by starting `kube-apiserver` with `--service-account-extend-token-expiration=false`. ([#95667](https://github.com/kubernetes/kubernetes/pull/95667), [@zshihang](https://github.com/zshihang)) [SIG API Machinery, Auth, Cluster Lifecycle and Testing]
### Feature
- A new histogram metric to track the time it took to delete a job by the ttl-after-finished controller ([#98676](https://github.com/kubernetes/kubernetes/pull/98676), [@ahg-g](https://github.com/ahg-g)) [SIG Apps and Instrumentation]
- AWS cloudprovider supports auto-discovering subnets without any kubernetes.io/cluster/<clusterName> tags. It also supports additional service annotation service.beta.kubernetes.io/aws-load-balancer-subnets to manually configure the subnets. ([#97431](https://github.com/kubernetes/kubernetes/pull/97431), [@kishorj](https://github.com/kishorj)) [SIG Cloud Provider]
- Add --permit-address-sharing flag to kube-apiserver to listen with SO_REUSEADDR. While allowing to listen on wildcard IPs like 0.0.0.0 and specific IPs in parallel, it avoid waiting for the kernel to release socket in TIME_WAIT state, and hence, considably reducing kube-apiserver restart times under certain conditions. ([#93861](https://github.com/kubernetes/kubernetes/pull/93861), [@sttts](https://github.com/sttts)) [SIG API Machinery]
- Add `csi_operations_seconds` metric on kubelet that exposes CSI operations duration and status for node CSI operations. ([#98979](https://github.com/kubernetes/kubernetes/pull/98979), [@Jiawei0227](https://github.com/Jiawei0227)) [SIG Instrumentation and Storage]
- Add `migrated` field into `storage_operation_duration_seconds` metric ([#99050](https://github.com/kubernetes/kubernetes/pull/99050), [@Jiawei0227](https://github.com/Jiawei0227)) [SIG Apps, Instrumentation and Storage]
- Add bash-completion for comma separated list on `kubectl get` ([#98301](https://github.com/kubernetes/kubernetes/pull/98301), [@phil9909](https://github.com/phil9909)) [SIG CLI]
- Added support for installing arm64 node artifacts. ([#99242](https://github.com/kubernetes/kubernetes/pull/99242), [@liu-cong](https://github.com/liu-cong)) [SIG Cloud Provider]
- Feature gate RootCAConfigMap is graduated to GA in 1.21 and will be removed in 1.22. ([#98033](https://github.com/kubernetes/kubernetes/pull/98033), [@zshihang](https://github.com/zshihang)) [SIG API Machinery and Auth]
- Kubeadm: during "init" and "join" perform preflight validation on the host / node name and throw warnings if a name is not compliant ([#99194](https://github.com/kubernetes/kubernetes/pull/99194), [@pacoxu](https://github.com/pacoxu)) [SIG Cluster Lifecycle]
- Kubectl: `kubectl get` will omit managed fields by default now. Users could set `--show-managed-fields` to true to show managedFields when the output format is either `json` or `yaml`. ([#96878](https://github.com/kubernetes/kubernetes/pull/96878), [@knight42](https://github.com/knight42)) [SIG CLI and Testing]
- Metrics can now be disabled explicitly via a command line flag (i.e. '--disabled-metrics=bad_metric1,bad_metric2') ([#99217](https://github.com/kubernetes/kubernetes/pull/99217), [@logicalhan](https://github.com/logicalhan)) [SIG API Machinery, Cluster Lifecycle and Instrumentation]
- TTLAfterFinished is now beta and enabled by default ([#98678](https://github.com/kubernetes/kubernetes/pull/98678), [@ahg-g](https://github.com/ahg-g)) [SIG Apps and Auth]
- The `RunAsGroup` feature has been promoted to GA in this release. ([#94641](https://github.com/kubernetes/kubernetes/pull/94641), [@krmayankk](https://github.com/krmayankk)) [SIG Auth and Node]
- Turn CronJobControllerV2 on by default. ([#98878](https://github.com/kubernetes/kubernetes/pull/98878), [@soltysh](https://github.com/soltysh)) [SIG Apps]
- UDP protocol support for Agnhost connect subcommand ([#98639](https://github.com/kubernetes/kubernetes/pull/98639), [@knabben](https://github.com/knabben)) [SIG Testing]
- Upgrades `IPv6Dualstack` to `Beta` and turns it on by default. Clusters new and existing will not be affected until user starting adding secondary pod and service cidrs cli flags as described here: https://github.com/kubernetes/enhancements/tree/master/keps/sig-network/563-dual-stack ([#98969](https://github.com/kubernetes/kubernetes/pull/98969), [@khenidak](https://github.com/khenidak)) [SIG API Machinery, Apps, Cloud Provider, Network and Node]
### Documentation
- Fix ALPHA stability level reference link ([#98641](https://github.com/kubernetes/kubernetes/pull/98641), [@Jeffwan](https://github.com/Jeffwan)) [SIG Auth, Cloud Provider, Instrumentation and Storage]
### Failing Test
- Escape the special characters like `[`, `]` and ` ` that exist in vsphere windows path ([#98830](https://github.com/kubernetes/kubernetes/pull/98830), [@liyanhui1228](https://github.com/liyanhui1228)) [SIG Storage and Windows]
- Kube-proxy: fix a bug on UDP NodePort Services where stale conntrack entries may blackhole the traffic directed to the NodePort. ([#98305](https://github.com/kubernetes/kubernetes/pull/98305), [@aojea](https://github.com/aojea)) [SIG Network]
### Bug or Regression

- Avoid duplicate error messages when runing kubectl edit quota ([#98201](https://github.com/kubernetes/kubernetes/pull/98201), [@pacoxu](https://github.com/pacoxu)) [SIG API Machinery and Apps]
- Cleanup subnet in frontend IP configs to prevent huge subnet request bodies in some scenarios. ([#98133](https://github.com/kubernetes/kubernetes/pull/98133), [@nilo19](https://github.com/nilo19)) [SIG Cloud Provider]
- Fix errors when accessing Windows container stats for Dockershim ([#98510](https://github.com/kubernetes/kubernetes/pull/98510), [@jsturtevant](https://github.com/jsturtevant)) [SIG Node and Windows]
