## Changelog since v1.19.11
## Changes by Kind
### Feature
- Kubernetes is now built using Go 1.15.13 ([#102809](https://github.com/kubernetes/kubernetes/pull/102809), [@thejoycekung](https://github.com/thejoycekung)) [SIG Cloud Provider, Instrumentation, Release and Testing]
### Failing Test
- Fixes the `should receive events on concurrent watches in same order` conformance test to work properly on clusters that auto-create additional configmaps in namespaces ([#101950](https://github.com/kubernetes/kubernetes/pull/101950), [@liggitt](https://github.com/liggitt)) [SIG API Machinery and Testing]
### Bug or Regression
- Avoid caching the Azure VMSS instances whose network profile is nil ([#100948](https://github.com/kubernetes/kubernetes/pull/100948), [@feiskyer](https://github.com/feiskyer)) [SIG Cloud Provider]
- Azure: avoid setting cached Sku when updating VMSS and VMSS instances ([#102005](https://github.com/kubernetes/kubernetes/pull/102005), [@feiskyer](https://github.com/feiskyer)) [SIG Cloud Provider]
- Fix a bug that a preemptor pod may exist as a phantom in the scheduler. ([#102498](https://github.com/kubernetes/kubernetes/pull/102498), [@Huang-Wei](https://github.com/Huang-Wei)) [SIG Scheduling]
- 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]
- Fix: delete non existing disk issue ([#102083](https://github.com/kubernetes/kubernetes/pull/102083), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider]
- Fixed false-positive uncertain volume attachments, which led to unexpected detachment of CSI migrated volumes ([#101737](https://github.com/kubernetes/kubernetes/pull/101737), [@Jiawei0227](https://github.com/Jiawei0227)) [SIG Apps and Storage]
- Fixed garbage collection of dangling VolumeAttachments for PersistentVolumes migrated to CSI on startup of kube-controller-manager. ([#102176](https://github.com/kubernetes/kubernetes/pull/102176), [@timebertt](https://github.com/timebertt)) [SIG Apps and Storage]
- Fixes an issue where default RBAC policy could fail to reconcile on API server startup if an error was encountered ([#101954](https://github.com/kubernetes/kubernetes/pull/101954), [@voutcn](https://github.com/voutcn)) [SIG Auth]
- Improve speed of vSphere PV provisioning and reduce number of API calls ([#102351](https://github.com/kubernetes/kubernetes/pull/102351), [@gnufied](https://github.com/gnufied)) [SIG Cloud Provider and Storage]

## Changelog since v1.19.9
## Important Security Information
This release contains changes that address the following vulnerabilities:
### CVE-2021-25735: Validating Admission Webhook does not observe some previous fields
A security issue was discovered in kube-apiserver that could allow node
updates to bypass a Validating Admission Webhook. You are only affected
by this vulnerability if you run a Validating Admission Webhook for Nodes
that denies admission based at least partially on the old state of the
Node object.
**Note**: This only impacts validating admission plugins that rely on old
values in certain fields, and does not impact calls from kubelets that go
through the built-in NodeRestriction admission plugin.
**Affected Versions**:
- kube-apiserver v1.20.0 - v1.20.5
- kube-apiserver v1.19.0 - v1.19.9
- kube-apiserver <= v1.18.17
**Fixed Versions**:
- kube-apiserver v1.21.0
- kube-apiserver v1.20.6
- kube-apiserver v1.19.10
- kube-apiserver v1.18.18
This vulnerability was reported by Rogerio Bastos & Ari Lima from RedHat
**CVSS Rating:** Medium (6.5) [CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H)

- Regenerate protobuf code to fix CVE-2021-3121 ([#100515](https://github.com/kubernetes/kubernetes/pull/100515), [@joelsmith](https://github.com/joelsmith)) [SIG API Machinery, Auth, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Node and Storage]
### Feature
- 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]
- AWS cloudprovider will ignore provisioning load balancers if the annotation service.beta.kubernetes.io/aws-load-balancer-type is external or nlb-ip ([#97975](https://github.com/kubernetes/kubernetes/pull/97975), [@kishorj](https://github.com/kishorj)) [SIG Cloud Provider]
- Kubernetes is now built using go1.15.10 ([#100520](https://github.com/kubernetes/kubernetes/pull/100520), [@cpanato](https://github.com/cpanato)) [SIG Cloud Provider, Instrumentation, Release and Testing]
### Bug or Regression
- Fixed a bug where a high churn of events was causing master instability by reducing the maximum number of objects (events) attached to a single etcd lease. ([#100450](https://github.com/kubernetes/kubernetes/pull/100450), [@mborsz](https://github.com/mborsz)) [SIG API Machinery and Instrumentation]
- Fixed a race condition on API server startup ensuring previously created webhook configurations are effective before the first write request is admitted. ([#95783](https://github.com/kubernetes/kubernetes/pull/95783), [@roycaihw](https://github.com/roycaihw)) [SIG API Machinery]
- Fixes a data race issue in the priority and fairness API server filter ([#100669](https://github.com/kubernetes/kubernetes/pull/100669), [@tkashem](https://github.com/tkashem)) [SIG API Machinery]
- Kubectl: Fixed panic when describing an ingress backend without an API Group ([#100542](https://github.com/kubernetes/kubernetes/pull/100542), [@eddiezane](https://github.com/eddiezane)) [SIG CLI]
- Reverts breaking change to inline AzureFile volumes in v1.19.7-v1.19.9; referenced secrets are now correctly searched for in the same namespace as the pod as in previous releases. ([#100398](https://github.com/kubernetes/kubernetes/pull/100398), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider and Storage]
- The endpointslice mirroring controller mirrors endpoints annotations and labels to the generated endpoint slices, it also ensures that updates on any of these fields on the endpoints are mirrored.
The well-known annotation endpoints.kubernetes.io/last-change-trigger-time is skipped and not mirrored. ([#100443](https://github.com/kubernetes/kubernetes/pull/100443), [@aojea](https://github.com/aojea)) [SIG Apps, Network and Testing]
- The maximum number of ports allowed in EndpointSlices has been increased from 100 to 20,000 ([#99795](https://github.com/kubernetes/kubernetes/pull/99795), [@robscott](https://github.com/robscott)) [SIG Network]

## Changelog since v1.19.2
## Changes by Kind
### Feature
- Kubernetes is now built using go1.15.2
- build: Update to k/[email protected] (supports go1.15.2)
- build: Use go-runner:buster-v2.0.1 (built using go1.15.1)
- bazel: Replace --features with Starlark build settings flag
- hack/lib/util.sh: some bash cleanups
- switched one spot to use kube::logging
- make kube::util::find-binary return an error when it doesn't find
anything so that hack scripts fail fast instead of with '' binary not
found errors.
- this required deleting some genfeddoc stuff. the binary no longer
exists in k/k repo since we removed federation/, and I don't see it
in https://github.com/kubernetes-sigs/kubefed/ either. I'm assuming
that it's gone for good now.
- bazel: output go_binary rule directly from go_binary_conditional_pure
From: [@mikedanese](https://github.com/mikedanese):
Instead of aliasing. Aliases are annoying in a number of ways. This is
specifically bugging me now because they make the action graph harder to
analyze programmatically. By using aliases here, we would need to handle
potentially aliased go_binary targets and dereference to the effective
target.
The comment references an issue with `pure = select(...)` which appears
to be resolved considering this now builds.
- make kube::util::find-binary not dependent on bazel-out/ structure
Implement an aspect that outputs go_build_mode metadata for go binaries,

## Changelog since v1.19.0
## Changes by Kind
### Bug or Regression
- Azure: fix a bug that kube-controller-manager would panic if wrong Azure VMSS name is configured ([#94306](https://github.com/kubernetes/kubernetes/pull/94306), [@knight42](https://github.com/knight42)) [SIG Cloud Provider]
- Build/lib/release: Explicitly use '--platform' in building server images
When we switched to go-runner for building the apiserver,
controller-manager, and scheduler server components, we no longer
reference the individual architectures in the image names, specifically
in the 'FROM' directive of the server image Dockerfiles.
As a result, server images for non-amd64 images copy in the go-runner
amd64 binary instead of the go-runner that matches that architecture.
This commit explicitly sets the '--platform=linux/${arch}' to ensure
we're pulling the correct go-runner arch from the manifest list.
Before:
`FROM ${base_image}`
After:
`FROM --platform=linux/${arch} ${base_image}` ([#94613](https://github.com/kubernetes/kubernetes/pull/94613), [@justaugustus](https://github.com/justaugustus)) [SIG Release]
- Fix a concurrent map writes error in kubelet ([#93773](https://github.com/kubernetes/kubernetes/pull/93773), [@knight42](https://github.com/knight42)) [SIG Node]
- Fix a regression where kubeadm bails out with a fatal error when an optional version command line argument is supplied to the "kubeadm upgrade plan" command ([#94421](https://github.com/kubernetes/kubernetes/pull/94421), [@rosti](https://github.com/rosti)) [SIG Cluster Lifecycle]
- Fixed bug in reflector that couldn't recover from "Too large resource version" errors with API servers 1.17.0-1.18.5 ([#94316](https://github.com/kubernetes/kubernetes/pull/94316), [@janeczku](https://github.com/janeczku)) [SIG API Machinery]
- Kubeadm: make the kubeconfig files for the kube-controller-manager and kube-scheduler use the LocalAPIEndpoint instead of the ControlPlaneEndpoint. This makes kubeadm clusters more reseliant to version skew problems during immutable upgrades: https://kubernetes.io/docs/setup/release/version-skew-policy/#kube-controller-manager-kube-scheduler-and-cloud-controller-manager ([#94398](https://github.com/kubernetes/kubernetes/pull/94398), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
- Update default etcd server version to 3.4.13 ([#94536](https://github.com/kubernetes/kubernetes/pull/94536), [@jingyih](https://github.com/jingyih)) [SIG API Machinery, Cloud Provider, Cluster Lifecycle and Testing]
- Upon successful authorization check, an impersonated user is added to the system:authenticated group.
system:anonymous when impersonated is added to the system:unauthenticated group. ([#94408](https://github.com/kubernetes/kubernetes/pull/94408), [@tkashem](https://github.com/tkashem)) [SIG API Machinery and Testing]
- Use NLB Subnet CIDRs instead of VPC CIDRs in Health Check SG Rules ([#93515](https://github.com/kubernetes/kubernetes/pull/93515), [@t0rr3sp3dr0](https://github.com/t0rr3sp3dr0)) [SIG Cloud Provider]
### Other (Cleanup or Flake)
- Fixes the flooding warning messages about setting volume ownership for configmap/secret volumes ([#92878](https://github.com/kubernetes/kubernetes/pull/92878), [@jvanz](https://github.com/jvanz)) [SIG Instrumentation, Node and Storage]
- Kubeadm: remove the CoreDNS check for known image digests when applying the addon ([#94506](https://github.com/kubernetes/kubernetes/pull/94506), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]

## Changelog since v1.18.0
## What’s New (Major Themes)
### Deprecation warnings
SIG API Machinery implemented [warnings when using deprecated APIs](https://kubernetes.io/docs/reference/using-api/deprecation-policy/#rest-resources-aka-api-objects)
that are visible to `kubectl` users and API consumers, and metrics visible to cluster administrators.
Requests to a deprecated API are returned with a warning containing a target removal release and any replacement API.
Warnings can also be returned by [admission webhooks](https://kubernetes.io/docs/reference/access-authn-authz/extensible-admission-controllers/#admissionreview-response-warning),
and specified for [deprecated versions of custom resources](https://kubernetes.io/docs/tasks/extend-kubernetes/custom-resources/custom-resource-definition-versioning/#version-deprecation).
### Avoiding permanent beta
From Kubernetes 1.20 onwards, SIG Architecture will implement a new policy to transition all REST APIs out of beta within nine months. The idea behind the new policy is to avoid features staying in beta for a long time. Once a new API enters beta, it will have nine months to either:
- reach GA, and deprecate the beta, or
- have a new beta version _(and deprecate the previous beta)_.
If a REST API reaches the end of that nine-month countdown, then the next Kubernetes release will deprecate that API version. More information can be found on [the Kubernetes Blog](https://kubernetes.io/blog/2020/08/21/moving-forward-from-beta/).
### Expanded CLI support for debugging workloads and nodes
SIG CLI expanded on debugging with `kubectl` to support two new debugging workflows: debugging workloads by creating a copy, and debugging nodes by creating a container in host namespaces. These can be convenient to:
- Insert a debug container in clusters that don’t have ephemeral containers enabled
- Modify a crashing container for easier debugging by changing its image, for example to busybox, or its command, for example, to `sleep 1d` so you have time to `kubectl exec`.
- Inspect configuration files on a node's host filesystem
Since these new workflows don’t require any new cluster features, they’re available for experimentation with your existing clusters via `kubectl alpha debug`. We’d love to hear your feedback on debugging with `kubectl`. Reach us by opening an issue, visiting [#sig-cli](https://kubernetes.slack.com/messages/sig-cli) or commenting on enhancement [#1441](https://features.k8s.io/1441).
### Structured logging
SIG Instrumentation standardized the structure of log messages and references to Kubernetes objects. Structured logging makes parsing, processing, storing, querying and analyzing logs easier. New methods in the klog library enforce log message structure.
### EndpointSlices are now enabled by default
EndpointSlices are an exciting new API that provides a scalable and extensible alternative to the Endpoints API. EndpointSlices track IP addresses, ports, readiness, and topology information for Pods backing a Service.
In Kubernetes 1.19 this feature will be enabled by default with kube-proxy reading from EndpointSlices instead of Endpoints. Although this will mostly be an invisible change, it should result in noticeable scalability improvements in large clusters. It will also enable significant new features in future Kubernetes releases like Topology Aware Routing.
### Ingress graduates to General Availability
SIG Network has graduated the widely used [Ingress API](https://kubernetes.io/docs/concepts/services-networking/ingress/) to general availability in Kubernetes 1.19. This change recognises years of hard work by Kubernetes contributors, and paves the way for further work on future networking APIs in Kubernetes.
### seccomp graduates to General Availability
The seccomp (secure computing mode) support for Kubernetes has graduated to General Availability (GA). This feature can be used to increase the workload security by restricting the system calls for a Pod (applies to all containers) or single containers.
Technically this means that a first class `seccompProfile` field has been added to the Pod and Container `securityContext` objects:
```yaml
securityContext:
seccompProfile:
type: RuntimeDefault|Localhost|Unconfined # choose one of the three
localhostProfile: my-profiles/profile-allow.json # only necessary if type == Localhost
```
The support for `seccomp.security.alpha.kubernetes.io/pod` and `container.seccomp.security.alpha.kubernetes.io/...` annotations are now deprecated, and will be removed in Kubernetes v1.22.0. Right now, an automatic version skew handling will convert the new field into the annotations and vice versa. This means there is no action required for converting existing workloads in a cluster.
You can find more information about how to restrict container system calls with seccomp in the new [documentation page on Kubernetes.io][seccomp-docs]
[seccomp-docs]: https://kubernetes.io/docs/tutorials/clusters/seccomp/
### Production images moved to community control
As of Kuberenetes v1.19, Kubernetes container images are stored on a community-controlled storage bucket,
located at `{asia,eu,us}.gcr.io/k8s-artifacts-prod`. The `k8s.gcr.io` vanity domain has been updated
to this new bucket. This brings production artifacts under community control.
### KubeSchedulerConfiguration graduates to Beta
SIG Scheduling graduates `KubeSchedulerConfiguration` to Beta. The [KubeSchedulerConfiguration](https://kubernetes.io/docs/reference/scheduling/config) feature allows you to tune the algorithms and other settings of the kube-scheduler. You can easily enable or disable specific functionality (contained in plugins) in selected scheduling phases without having to rewrite the rest of the configuration. Furthermore, a single kube-scheduler instance can serve different configurations, called profiles. Pods can select the profile they want to be scheduled under via the `.spec.schedulerName` field.
### CSI Migration - AzureDisk and vSphere (beta)
In-tree volume plugins and all cloud provider dependencies are being moved out of the Kubernetes core. The CSI migration feature allows existing volumes using the legacy APIs to continue to function even when the code has been removed, by routing all the volume operations to the respective CSI driver. The AzureDisk and vSphere implementations of this feature have been promoted to beta.
### Storage capacity tracking
Traditionally, the Kubernetes scheduler was based on the assumption that additional persistent storage is available everywhere in the cluster and has infinite capacity. Topology constraints addressed the first point, but up to now pod scheduling was still done without considering that the remaining storage capacity may not be enough to start a new pod. [Storage capacity tracking](https://github.com/kubernetes/enhancements/tree/master/keps/sig-storage/1472-storage-capacity-tracking), a new alpha feature, addresses that by adding an API for a CSI driver to report storage capacity and uses that information in the Kubernetes scheduler when choosing a node for a pod. This feature serves as a stepping stone for supporting dynamic provisioning for local volumes and other volume types that are more capacity constrained.
### CSI Volume health monitoring
The alpha version of CSI health monitoring is being released with Kubernetes 1.19. This feature enables CSI Drivers to share abnormal volume conditions from the underlying storage systems with Kubernetes so that they can be reported as events on PVCs or Pods. This feature serves as a stepping stone towards programmatic detection and resolution of individual volume health issues by Kubernetes.
### General ephemeral volumes
Kubernetes provides volume plugins whose lifecycle is tied to a pod and can be used as scratch space (e.g. the builtin “empty dir” volume type) or to load some data in to a pod (e.g. the builtin ConfigMap and Secret volume types or “CSI inline volumes”). The new [generic ephemeral volumes](https://github.com/kubernetes/enhancements/tree/master/keps/sig-storage/1698-generic-ephemeral-volumes) alpha feature allows any existing storage driver that supports dynamic provisioning to be used as an ephemeral volume with the volume’s lifecycle bound to the Pod.
- It can be used to provide scratch storage that is different from the root disk, for example persistent memory, or a separate local disk on that node.
- All StorageClass parameters for volume provisioning are supported.
- All features supported with PersistentVolumeClaims are supported, such as storage capacity tracking, snapshots and restore, and volume resizing.
### Immutable Secrets and ConfigMaps (beta)
Secret and ConfigMap volumes can be marked as immutable, which significantly reduces load on the API server if there are many Secret and ConfigMap volumes in the cluster.
See [ConfigMap](https://kubernetes.io/docs/concepts/configuration/configmap/) and [Secret](https://kubernetes.io/docs/concepts/configuration/secret/) for more information.
### CSI Proxy for Windows
The CSI Proxy for Windows is being promoted to beta along with the 1.19 release. This CSI Proxy enables CSI Drivers to run on Windows by allowing containers in Windows to perform privileged storage operations. At beta, the CSI Proxy for Windows supports storage drivers using direct attached disks and SMB.
### Dashboard v2
SIG UI has released v2 of the Kubernetes Dashboard add-on. You can find the most recent release in the [kubernetes/dashboard](https://github.com/kubernetes/dashboard/releases) repository. Kubernetes Dashboard now includes CRD support, new translations, and an updated version of AngularJS.
### Windows containerd support graduates to beta
Initially introduced in Kubernetes 1.18, Windows containerd support goes to Beta on this release. This includes the added support for Windows Server version 2004 (complete version compatibility can be found in the [documentation for Windows](https://kubernetes.io/docs/setup/production-environment/windows/intro-windows-in-kubernetes/#cri-containerd)).
SIG Windows is also including several addition to this release:
- Direct Server Return (DSR) mode support, allowing large numbers of services to scale up efficiently
- Windows containers now honor CPU limits
- Performance improvements for collections of metrics and summary
### Increase the Kubernetes support window to one year
As of Kubernetes 1.19, bugfix support via patch releases for a Kubernetes minor release has increased from 9 months to 1 year.
A survey conducted in early 2019 by the working group (WG) Long Term Support (LTS) showed that a significant subset of Kubernetes end-users fail to upgrade within the previous 9-month support period.
A yearly support period provides the cushion end-users appear to desire, and is more in harmony with familiar annual planning cycles.
## Known Issues
The new storage capacity tracking alpha feature is known to be affected by a limitation of the WaitForFirstConsumer volume binding mode: [#94217](https://github.com/kubernetes/kubernetes/issues/94217)
## Urgent Upgrade Notes
### (No, really, you MUST read this before you upgrade)
- ACTION REQUIRED: Switch core master base images (kube-controller-manager) from debian to distroless. If you need Flex Volumes support using scripts, please build your own image with required packages (like bash) ([#91329](https://github.com/kubernetes/kubernetes/pull/91329), [@dims](https://github.com/dims)) [SIG Cloud Provider, Release, Storage and Testing]
- ACTION REQUIRED: Support for basic authentication via the --basic-auth-file flag has been removed. Users should migrate to --token-auth-file for similar functionality. ([#89069](https://github.com/kubernetes/kubernetes/pull/89069), [@enj](https://github.com/enj)) [SIG API Machinery]
- Azure blob disk feature(`kind`: `Shared`, `Dedicated`) has been deprecated, you should use `kind`: `Managed` in `kubernetes.io/azure-disk` storage class. ([#92905](https://github.com/kubernetes/kubernetes/pull/92905), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider and Storage]
- CVE-2020-8559 (Medium): Privilege escalation from compromised node to cluster. See https://github.com/kubernetes/kubernetes/issues/92914 for more details.
The API Server will no longer proxy non-101 responses for upgrade requests. This could break proxied backends (such as an extension API server) that respond to upgrade requests with a non-101 response code. ([#92941](https://github.com/kubernetes/kubernetes/pull/92941), [@tallclair](https://github.com/tallclair)) [SIG API Machinery]
- Kubeadm does not set the deprecated '--cgroup-driver' flag in /var/lib/kubelet/kubeadm-flags.env, it will be set in the kubelet config.yaml. If you have this flag in /var/lib/kubelet/kubeadm-flags.env or /etc/default/kubelet (/etc/sysconfig/kubelet for RPMs) please remove it and set the value using KubeletConfiguration ([#90513](https://github.com/kubernetes/kubernetes/pull/90513), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]
- Kubeadm now respects user specified etcd versions in the ClusterConfiguration and properly uses them. If users do not want to stick to the version specified in the ClusterConfiguration, they should edit the kubeadm-config config map and delete it. ([#89588](https://github.com/kubernetes/kubernetes/pull/89588), [@rosti](https://github.com/rosti)) [SIG Cluster Lifecycle]
- Kubeadm respects resolvConf value set by user even if systemd-resolved service is active. kubeadm no longer sets the flag in '--resolv-conf' in /var/lib/kubelet/kubeadm-flags.env. If you have this flag in /var/lib/kubelet/kubeadm-flags.env or /etc/default/kubelet (/etc/sysconfig/kubelet for RPMs) please remove it and set the value using KubeletConfiguration ([#90394](https://github.com/kubernetes/kubernetes/pull/90394), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]
- Kubeadm: Move the "kubeadm init" phase "kubelet-start" later in the init workflow, after the "kubeconfig" phase. This makes kubeadm start the kubelet only after the KubeletConfiguration component config file (/var/lib/kubelet/config.yaml) is generated and solves a problem where init systems like OpenRC cannot crashloop the kubelet service. ([#90892](https://github.com/kubernetes/kubernetes/pull/90892), [@xphoniex](https://github.com/xphoniex)) [SIG Cluster Lifecycle]
- The 'kubeadm config upload' command is finally removed after a full GA deprecation cycle. If you still use it, please, use 'kubeadm init phase upload-config' instead ([#92610](https://github.com/kubernetes/kubernetes/pull/92610), [@rosti](https://github.com/rosti)) [SIG Cluster Lifecycle]
- Upgrade kubescheduler.config.k8s.io/v1alpha2 to kubescheduler.config.k8s.io/v1beta1
- `.bindTimeoutSeconds` was moved as part of plugin args for `VolumeBinding`,
which can be configured separately per profile.
- `.extenders` are updated to satisfy API standards. In particular:
- `.extenders` decoding is case sensitive. All fields are affected.
- `.extenders[*].httpTimeout` is of type `metav1.Duration`.
- `.extenders[*].enableHttps` is renamed to `.extenders[*].enableHTTPS`.
- `RequestedToCapacityRatio` args decoding is case sensitive. All fields are affected.
- `DefaultPodTopologySpread` plugin is renamed to `SelectorSpread`.
- `Unreserve` extension point is removed from Profile definition. All `Reserve`
plugins implement an `Unreserve` call.
- `.disablePreemption` was removed. Users can disable preemption by disabling the
"DefaultPreemption" PostFilter plugin. ([#91420](https://github.com/kubernetes/kubernetes/pull/91420), [@pancernik](https://github.com/pancernik)) [SIG Scheduling]
## Changes by Kind
### Deprecation
- Added support for vSphere in-tree volumes migration to vSphere CSI driver. The in-tree vSphere Volume plugin will be deprecated and removed in a future release.
Users that self-deploy Kubernetes on vSphere should enable CSIMigration + CSIMigrationvSphere features and install the vSphere CSI Driver (https://github.com/kubernetes-sigs/vsphere-csi-driver) to avoid disruption to existing Pod and PVC objects at that time. Users should start using the vSphere CSI driver directly for any new volumes.
The CSI Migration feature for vSphere Volume also requires minimum vSphere vCenter/ESXi Version to be 7.0u1 and minimum HW Version to be VM version 15.
vSAN raw policy parameter is deprecated for the in-tree vSphere Volume plugin and will be removed in a future release. ([#90911](https://github.com/kubernetes/kubernetes/pull/90911), [@divyenpatel](https://github.com/divyenpatel)) [SIG API Machinery, Node and Storage]
- Apiextensions.k8s.io/v1beta1 is deprecated in favor of apiextensions.k8s.io/v1 ([#90673](https://github.com/kubernetes/kubernetes/pull/90673), [@deads2k](https://github.com/deads2k)) [SIG API Machinery]

- Ensure that volume capability and staging target fields are present in nodeExpansion CSI calls
Behaviour of NodeExpandVolume being called between NodeStage and NodePublish is deprecated for CSI volumes. CSI drivers should support calling NodeExpandVolume after NodePublish if they have node EXPAND_VOLUME capability ([#86968](https://github.com/kubernetes/kubernetes/pull/86968), [@gnufied](https://github.com/gnufied)) [SIG Storage]
- Feat: azure disk migration go beta in 1.19. Feature gates CSIMigration to Beta (on by default) and CSIMigrationAzureDisk to Beta (off by default since it requires installation of the AzureDisk CSI Driver)
The in-tree AzureDisk plugin "kubernetes.io/azure-disk" is now deprecated and will be removed in 1.23. Users should enable CSIMigration + CSIMigrationAzureDisk features and install the AzureDisk CSI Driver (https://github.com/kubernetes-sigs/azuredisk-csi-driver) to avoid disruption to existing Pod and PVC objects at that time.
Users should start using the AzureDisk CSI Driver directly for any new volumes. ([#90896](https://github.com/kubernetes/kubernetes/pull/90896), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider and Storage]
- Kube-apiserver: the componentstatus API is deprecated. This API provided status of etcd, kube-scheduler, and kube-controller-manager components, but only worked when those components were local to the API server, and when kube-scheduler and kube-controller-manager exposed unsecured health endpoints. Instead of this API, etcd health is included in the kube-apiserver health check and kube-scheduler/kube-controller-manager health checks can be made directly against those components' health endpoints. ([#93570](https://github.com/kubernetes/kubernetes/pull/93570), [@liggitt](https://github.com/liggitt)) [SIG API Machinery, Apps and Cluster Lifecycle]

- Kubeadm: deprecate the "kubeadm alpha kubelet config enable-dynamic" command. To continue using the feature please defer to the guide for "Dynamic Kubelet Configuration" at k8s.io. ([#92881](https://github.com/kubernetes/kubernetes/pull/92881), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
- Kubeadm: deprecate the feature `--experimental-kustomize` in favor of `--experimental-patches`. The supported patch formats are the same as "kubectl patch". They are read as files from a directory and can be applied to kubeadm components during init/join/upgrade. Only patching of static Pods is supported for the time being. ([#92017](https://github.com/kubernetes/kubernetes/pull/92017), [@neolit123](https://github.com/neolit123))
- Kubeadm: remove the deprecated "--use-api" flag for "kubeadm alpha certs renew" ([#90143](https://github.com/kubernetes/kubernetes/pull/90143), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]

### API Change
- A new alpha-level field, `SupportsFsGroup`, has been introduced for CSIDrivers to allow them to specify whether they support volume ownership and permission modifications. The `CSIVolumeSupportFSGroup` feature gate must be enabled to allow this field to be used. ([#92001](https://github.com/kubernetes/kubernetes/pull/92001), [@huffmanca](https://github.com/huffmanca)) [SIG API Machinery, CLI and Storage]
- Added pod version skew strategy for seccomp profile to synchronize the deprecated annotations with the new API Server fields. Please see the corresponding section [in the KEP](https://github.com/kubernetes/enhancements/blob/master/keps/sig-node/135-seccomp/README.md#version-skew-strategy) for more detailed explanations. ([#91408](https://github.com/kubernetes/kubernetes/pull/91408), [@saschagrunert](https://github.com/saschagrunert)) [SIG Apps, Auth, CLI and Node]

- CertificateSigningRequest API conditions were updated:
- a `status` field was added; this field defaults to `True`, and may only be set to `True` for `Approved`, `Denied`, and `Failed` conditions
- a `lastTransitionTime` field was added
- a `Failed` condition type was added to allow signers to indicate permanent failure; this condition can be added via the `certificatesigningrequests/status` subresource.
- `Approved` and `Denied` conditions are mutually exclusive

- Fixed: log timestamps now include trailing zeros to maintain a fixed width ([#91207](https://github.com/kubernetes/kubernetes/pull/91207), [@iamchuckss](https://github.com/iamchuckss)) [SIG Apps and Node]
- Generic ephemeral volumes, a new alpha feature under the `GenericEphemeralVolume` feature gate, provide a more flexible alternative to `EmptyDir` volumes: as with `EmptyDir`, volumes are created and deleted for each pod automatically by Kubernetes. But because the normal provisioning process is used (`PersistentVolumeClaim`), storage can be provided by third-party storage vendors and all of the usual volume features work. Volumes don't need to be empt; for example, restoring from snapshot is supported. ([#92784](https://github.com/kubernetes/kubernetes/pull/92784), [@pohly](https://github.com/pohly)) [SIG API Machinery, Apps, Auth, CLI, Instrumentation, Node, Scheduling, Storage and Testing]

Ingress and IngressClass types in the `extensions/v1beta1` and `networking.k8s.io/v1beta1` API versions are deprecated and will no longer be served in 1.22+. Persisted objects can be accessed via the `networking.k8s.io/v1` API. Notable changes in v1 Ingress objects (v1beta1 field names are unchanged):
- `spec.backend` -> `spec.defaultBackend`
- `serviceName` -> `service.name`
- `servicePort` -> `service.port.name` (for string values)
- `servicePort` -> `service.port.number` (for numeric values)
- `pathType` no longer has a default value in v1; "Exact", "Prefix", or "ImplementationSpecific" must be specified
Other Ingress API updates:
- backends can now be resource or service backends
- `path` is no longer required to be a valid regular expression ([#89778](https://github.com/kubernetes/kubernetes/pull/89778), [@cmluciano](https://github.com/cmluciano)) [SIG API Machinery, Apps, CLI, Network and Testing]

- `RequestedToCapacityRatioArgs` encoding is now strict ([#91603](https://github.com/kubernetes/kubernetes/pull/91603), [@pancernik](https://github.com/pancernik)) [SIG Scheduling]
- `v1beta1` Scheduler `Extender` encoding is case-sensitive (`v1alpha1`/`v1alpha2` was case-insensitive), its `httpTimeout` field uses duration encoding (for example, one second is specified as `"1s"`), and the `enableHttps` field in `v1alpha1`/`v1alpha2` was renamed to `enableHTTPS`.

### Feature
- A defaultpreemption plugin is registered and enabled in scheduler which replaces the legacy hard-coded Pod preemption logic. ([#92049](https://github.com/kubernetes/kubernetes/pull/92049), [@Huang-Wei](https://github.com/Huang-Wei)) [SIG Scheduling and Testing]
- A new extension point `PostFilter` is introduced to scheduler framework which runs after Filter phase to resolve scheduling filter failures. A typical implementation is running preemption logic.

- ACTION REQUIRED : In CoreDNS v1.7.0, [metrics names have been changed](https://github.com/coredns/coredns/blob/master/notes/coredns-1.7.0.md#metric-changes) which will be backward incompatible with existing reporting formulas that use the old metrics' names. Adjust your formulas to the new names before upgrading.
Kubeadm now includes CoreDNS version v1.7.0. Some of the major changes include:
- Fixed a bug that could cause CoreDNS to stop updating service records.
- Fixed a bug in the forward plugin where only the first upstream server is always selected no matter which policy is set.
- Remove already deprecated options `resyncperiod` and `upstream` in the Kubernetes plugin.
- Includes Prometheus metrics name changes (to bring them in line with standard Prometheus metrics naming convention). They will be backward incompatible with existing reporting formulas that use the old metrics' names.
- The federation plugin (allows for v1 Kubernetes federation) has been removed.

## Changelog since v1.19.0-rc.3
## Changes by Kind
### Deprecation
- Kube-apiserver: the componentstatus API is deprecated. This API provided status of etcd, kube-scheduler, and kube-controller-manager components, but only worked when those components were local to the API server, and when kube-scheduler and kube-controller-manager exposed unsecured health endpoints. Instead of this API, etcd health is included in the kube-apiserver health check and kube-scheduler/kube-controller-manager health checks can be made directly against those components' health endpoints. ([#93570](https://github.com/kubernetes/kubernetes/pull/93570), [@liggitt](https://github.com/liggitt)) [SIG API Machinery, Apps and Cluster Lifecycle]
### Bug or Regression
- A panic in the apiserver caused by the `informer-sync` health checker is now fixed. ([#93600](https://github.com/kubernetes/kubernetes/pull/93600), [@ialidzhikov](https://github.com/ialidzhikov)) [SIG API Machinery]
- EndpointSliceMirroring controller now copies labels from Endpoints to EndpointSlices. ([#93442](https://github.com/kubernetes/kubernetes/pull/93442), [@robscott](https://github.com/robscott)) [SIG Apps and Network]
- Kube-apiserver: jsonpath expressions with consecutive recursive descent operators are no longer evaluated for custom resource printer columns ([#93408](https://github.com/kubernetes/kubernetes/pull/93408), [@joelsmith](https://github.com/joelsmith)) [SIG API Machinery]
### Other (Cleanup or Flake)
- Build: Update to [email protected] and [email protected] ([#93667](https://github.com/kubernetes/kubernetes/pull/93667), [@justaugustus](https://github.com/justaugustus)) [SIG API Machinery, Release and Testing]

## Changelog since v1.19.0-rc.1
## Changes by Kind
### API Change
- A new alpha-level field, `SupportsFsGroup`, has been introduced for CSIDrivers to allow them to specify whether they support volume ownership and permission modifications. The `CSIVolumeSupportFSGroup` feature gate must be enabled to allow this field to be used. ([#92001](https://github.com/kubernetes/kubernetes/pull/92001), [@huffmanca](https://github.com/huffmanca)) [SIG API Machinery, CLI and Storage]
- The kube-controller-manager managed signers can now have distinct signing certificates and keys. See the help about `--cluster-signing-[signer-name]-{cert,key}-file`. `--cluster-signing-{cert,key}-file` is still the default. ([#90822](https://github.com/kubernetes/kubernetes/pull/90822), [@deads2k](https://github.com/deads2k)) [SIG API Machinery, Apps and Auth]
### Feature
- Added kube-apiserver metrics: apiserver_current_inflight_request_measures and, when API Priority and Fairness is enable, windowed_request_stats. ([#91177](https://github.com/kubernetes/kubernetes/pull/91177), [@MikeSpreitzer](https://github.com/MikeSpreitzer)) [SIG API Machinery, Instrumentation and Testing]
- Rename pod_preemption_metrics to preemption_metrics. ([#93256](https://github.com/kubernetes/kubernetes/pull/93256), [@ahg-g](https://github.com/ahg-g)) [SIG Instrumentation and Scheduling]
### Bug or Regression
- Do not add nodes labeled with kubernetes.azure.com/managed=false to backend pool of load balancer. ([#93034](https://github.com/kubernetes/kubernetes/pull/93034), [@matthias50](https://github.com/matthias50)) [SIG Cloud Provider]

- Fix: initial delay in mounting azure disk & file ([#93052](https://github.com/kubernetes/kubernetes/pull/93052), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider and Storage]
- Fixed the EndpointSliceController to correctly create endpoints for IPv6-only pods.
Fixed the EndpointController to allow IPv6 headless services, if the IPv6DualStack
feature gate is enabled, by specifying `ipFamily: IPv6` on the service. (This already
worked with the EndpointSliceController.) ([#91399](https://github.com/kubernetes/kubernetes/pull/91399), [@danwinship](https://github.com/danwinship)) [SIG Apps and Network]

## Changelog since v1.19.0-rc.0
## Urgent Upgrade Notes
### (No, really, you MUST read this before you upgrade)
- Azure blob disk feature(`kind`: `Shared`, `Dedicated`) has been deprecated, you should use `kind`: `Managed` in `kubernetes.io/azure-disk` storage class. ([#92905](https://github.com/kubernetes/kubernetes/pull/92905), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider and Storage]
## Changes by Kind
### Deprecation
- Kubeadm: deprecate the "kubeadm alpha kubelet config enable-dynamic" command. To continue using the feature please defer to the guide for "Dynamic Kubelet Configuration" at k8s.io. ([#92881](https://github.com/kubernetes/kubernetes/pull/92881), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
### API Change
- Added pod version skew strategy for seccomp profile to synchronize the deprecated annotations with the new API Server fields. Please see the corresponding section [in the KEP](https://github.com/kubernetes/enhancements/tree/master/keps/sig-node/135-seccomp#version-skew-strategy) for more detailed explanations. ([#91408](https://github.com/kubernetes/kubernetes/pull/91408), [@saschagrunert](https://github.com/saschagrunert)) [SIG Apps, Auth, CLI and Node]
- Custom Endpoints are now mirrored to EndpointSlices by a new EndpointSliceMirroring controller. ([#91637](https://github.com/kubernetes/kubernetes/pull/91637), [@robscott](https://github.com/robscott)) [SIG API Machinery, Apps, Auth, Cloud Provider, Instrumentation, Network and Testing]
- Generic ephemeral volumes, a new alpha feature under the `GenericEphemeralVolume` feature gate, provide a more flexible alternative to `EmptyDir` volumes: as with `EmptyDir`, volumes are created and deleted for each pod automatically by Kubernetes. But because the normal provisioning process is used (`PersistentVolumeClaim`), storage can be provided by third-party storage vendors and all of the usual volume features work. Volumes don't need to be empt; for example, restoring from snapshot is supported. ([#92784](https://github.com/kubernetes/kubernetes/pull/92784), [@pohly](https://github.com/pohly)) [SIG API Machinery, Apps, Auth, CLI, Instrumentation, Node, Scheduling, Storage and Testing]
### Feature
- ACTION REQUIRED : In CoreDNS v1.7.0, [metrics names have been changed](https://github.com/coredns/coredns/blob/master/notes/coredns-1.7.0.md#metric-changes) which will be backward incompatible with existing reporting formulas that use the old metrics' names. Adjust your formulas to the new names before upgrading.
Kubeadm now includes CoreDNS version v1.7.0. Some of the major changes include:
- Fixed a bug that could cause CoreDNS to stop updating service records.
- Fixed a bug in the forward plugin where only the first upstream server is always selected no matter which policy is set.
- Remove already deprecated options `resyncperiod` and `upstream` in the Kubernetes plugin.
- Includes Prometheus metrics name changes (to bring them in line with standard Prometheus metrics naming convention). They will be backward incompatible with existing reporting formulas that use the old metrics' names.
- The federation plugin (allows for v1 Kubernetes federation) has been removed.
More details are available in https://coredns.io/2020/06/15/coredns-1.7.0-release/ ([#92651](https://github.com/kubernetes/kubernetes/pull/92651), [@rajansandeep](https://github.com/rajansandeep)) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle and Instrumentation]
- Add tags support for Azure File Driver ([#92825](https://github.com/kubernetes/kubernetes/pull/92825), [@ZeroMagic](https://github.com/ZeroMagic)) [SIG Cloud Provider and Storage]
- Audit events for API requests to deprecated API versions now include a `"k8s.io/deprecated": "true"` audit annotation. If a target removal release is identified, the audit event includes a `"k8s.io/removal-release": "<majorVersion>.<minorVersion>"` audit annotation as well. ([#92842](https://github.com/kubernetes/kubernetes/pull/92842), [@liggitt](https://github.com/liggitt)) [SIG API Machinery and Instrumentation]
- Cloud node-controller use InstancesV2 ([#91319](https://github.com/kubernetes/kubernetes/pull/91319), [@gongguan](https://github.com/gongguan)) [SIG Apps, Cloud Provider, Scalability and Storage]
- Kubeadm: deprecate the "--csr-only" and "--csr-dir" flags of the "kubeadm init phase certs" subcommands. Please use "kubeadm alpha certs generate-csr" instead. This new command allows you to generate new private keys and certificate signing requests for all the control-plane components, so that the certificates can be signed by an external CA. ([#92183](https://github.com/kubernetes/kubernetes/pull/92183), [@wallrj](https://github.com/wallrj)) [SIG Cluster Lifecycle]
- Server-side apply behavior has been regularized in the case where a field is removed from the applied configuration. Removed fields which have no other owners are deleted from the live object, or reset to their default value if they have one. Safe ownership transfers, such as the transfer of a `replicas` field from a user to an HPA without resetting to the default value are documented in [Transferring Ownership](https://kubernetes.io/docs/reference/using-api/api-concepts/#transferring-ownership) ([#92661](https://github.com/kubernetes/kubernetes/pull/92661), [@jpbetz](https://github.com/jpbetz)) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation and Testing]
- Set CSIMigrationvSphere feature gates to beta.
Users should enable CSIMigration + CSIMigrationvSphere features and install the vSphere CSI Driver (https://github.com/kubernetes-sigs/vsphere-csi-driver) to move workload from the in-tree vSphere plugin "kubernetes.io/vsphere-volume" to vSphere CSI Driver.
Requires: vSphere vCenter/ESXi Version: 7.0u1, HW Version: VM version 15 ([#92816](https://github.com/kubernetes/kubernetes/pull/92816), [@divyenpatel](https://github.com/divyenpatel)) [SIG Cloud Provider and Storage]
- Support a smooth upgrade from client-side apply to server-side apply without conflicts, as well as support the corresponding downgrade. ([#90187](https://github.com/kubernetes/kubernetes/pull/90187), [@julianvmodesto](https://github.com/julianvmodesto)) [SIG API Machinery and Testing]
- Trace output in apiserver logs is more organized and comprehensive. Traces are nested, and for all non-long running request endpoints, the entire filter chain is instrumented (e.g. authentication check is included). ([#88936](https://github.com/kubernetes/kubernetes/pull/88936), [@jpbetz](https://github.com/jpbetz)) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation and Scheduling]
- `kubectl alpha debug` now supports debugging nodes by creating a debugging container running in the node's host namespaces. ([#92310](https://github.com/kubernetes/kubernetes/pull/92310), [@verb](https://github.com/verb)) [SIG CLI]
### Failing Test
- Kube-proxy iptables min-sync-period defaults to 1 sec. Previously, it was 0. ([#92836](https://github.com/kubernetes/kubernetes/pull/92836), [@aojea](https://github.com/aojea)) [SIG Network]
### Bug or Regression
- Dockershim security: pod sandbox now always run with `no-new-privileges` and `runtime/default` seccomp profile
dockershim seccomp: custom profiles can now have smaller seccomp profiles when set at pod level ([#90948](https://github.com/kubernetes/kubernetes/pull/90948), [@pjbgf](https://github.com/pjbgf)) [SIG Node]
- Eviction requests for pods that have a non-zero DeletionTimestamp will always succeed ([#91342](https://github.com/kubernetes/kubernetes/pull/91342), [@michaelgugino](https://github.com/michaelgugino)) [SIG Apps]
- Fix detection of image filesystem, disk metrics for devicemapper, detection of OOM Kills on 5.0+ linux kernels. ([#92919](https://github.com/kubernetes/kubernetes/pull/92919), [@dashpole](https://github.com/dashpole)) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation and Node]
- Fixed memory leak in endpointSliceTracker ([#92838](https://github.com/kubernetes/kubernetes/pull/92838), [@tnqn](https://github.com/tnqn)) [SIG Apps and Network]
- Kube-aggregator certificates are dynamically loaded on change from disk ([#92791](https://github.com/kubernetes/kubernetes/pull/92791), [@p0lyn0mial](https://github.com/p0lyn0mial)) [SIG API Machinery]
- Kube-up now includes CoreDNS version v1.7.0. Some of the major changes include:
- Fixed a bug that could cause CoreDNS to stop updating service records.
- Fixed a bug in the forward plugin where only the first upstream server is always selected no matter which policy is set.
- Remove already deprecated options `resyncperiod` and `upstream` in the Kubernetes plugin.
- Includes Prometheus metrics name changes (to bring them in line with standard Prometheus metrics naming convention). They will be backward incompatible with existing reporting formulas that use the old metrics' names.
- The federation plugin (allows for v1 Kubernetes federation) has been removed.
More details are available in https://coredns.io/2020/06/15/coredns-1.7.0-release/ ([#92718](https://github.com/kubernetes/kubernetes/pull/92718), [@rajansandeep](https://github.com/rajansandeep)) [SIG Cloud Provider]
- The apiserver will no longer proxy non-101 responses for upgrade requests. This could break proxied backends (such as an extension API server) that respond to upgrade requests with a non-101 response code. ([#92941](https://github.com/kubernetes/kubernetes/pull/92941), [@tallclair](https://github.com/tallclair)) [SIG API Machinery]
- The terminationGracePeriodSeconds from pod spec is respected for the mirror pod. ([#92442](https://github.com/kubernetes/kubernetes/pull/92442), [@tedyu](https://github.com/tedyu)) [SIG Node and Testing]
### Other (Cleanup or Flake)
- --cache-dir sets cache directory for both http and discovery, defaults to $HOME/.kube/cache ([#92910](https://github.com/kubernetes/kubernetes/pull/92910), [@soltysh](https://github.com/soltysh)) [SIG API Machinery and CLI]
- Fix: license issue in blob disk feature ([#92824](https://github.com/kubernetes/kubernetes/pull/92824), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider]

## Changelog since v1.19.0-beta.1
## Changes by Kind
### Deprecation
- Kubeadm: remove the deprecated "--use-api" flag for "kubeadm alpha certs renew" ([#90143](https://github.com/kubernetes/kubernetes/pull/90143), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]
- Scheduler's alpha feature 'ResourceLimitsPriorityFunction' is completely removed due to lack of usage ([#91883](https://github.com/kubernetes/kubernetes/pull/91883), [@SataQiu](https://github.com/SataQiu)) [SIG Scheduling and Testing]
### API Change
- Remove `BindTimeoutSeconds` from schedule configuration `KubeSchedulerConfiguration` ([#91580](https://github.com/kubernetes/kubernetes/pull/91580), [@cofyc](https://github.com/cofyc)) [SIG Scheduling and Testing]
- Resolve regression in metadata.managedFields handling in update/patch requests submitted by older API clients ([#91748](https://github.com/kubernetes/kubernetes/pull/91748), [@apelisse](https://github.com/apelisse)) [SIG API Machinery and Testing]
- The CertificateSigningRequest API is promoted to certificates.k8s.io/v1 with the following changes:
- `spec.signerName` is now required, and requests for `kubernetes.io/legacy-unknown` are not allowed to be created via the `certificates.k8s.io/v1` API
- `spec.usages` is now required, may not contain duplicate values, and must only contain known usages
- `status.conditions` may not contain duplicate types
- `status.conditions[*].status` is now required
- `status.certificate` must be PEM-encoded, and contain only CERTIFICATE blocks ([#91685](https://github.com/kubernetes/kubernetes/pull/91685), [@liggitt](https://github.com/liggitt)) [SIG API Machinery, Architecture, Auth, CLI and Testing]
- The Kubelet's `--cloud-provider` and `--cloud-config` options are now marked as deprecated. ([#90408](https://github.com/kubernetes/kubernetes/pull/90408), [@knabben](https://github.com/knabben)) [SIG Cloud Provider and Node]
### Feature
- A new extension point `PostFilter` is introduced to scheduler framework which runs after Filter phase to resolve scheduling filter failures. A typical implementation is running preemption logic. ([#91314](https://github.com/kubernetes/kubernetes/pull/91314), [@Huang-Wei](https://github.com/Huang-Wei)) [SIG Scheduling and Testing]
- Added --privileged flag to kubectl run ([#90569](https://github.com/kubernetes/kubernetes/pull/90569), [@brianpursley](https://github.com/brianpursley)) [SIG CLI]
- Enable feature Gate DefaultPodTopologySpread to use PodTopologySpread plugin to do defaultspreading. In doing so, legacy DefaultPodTopologySpread plugin is disabled. ([#91793](https://github.com/kubernetes/kubernetes/pull/91793), [@alculquicondor](https://github.com/alculquicondor)) [SIG Scheduling]
- Extend AWS azToRegion method to support Local Zones ([#90874](https://github.com/kubernetes/kubernetes/pull/90874), [@Jeffwan](https://github.com/Jeffwan)) [SIG Cloud Provider]
- Kube-Proxy now supports IPv6DualStack on Windows with the IPv6DualStack feature gate. ([#90853](https://github.com/kubernetes/kubernetes/pull/90853), [@kumarvin123](https://github.com/kumarvin123)) [SIG Network, Node and Windows]
- Kube-controller-manager: the `--experimental-cluster-signing-duration` flag is marked as deprecated for removal in v1.22, and is replaced with `--cluster-signing-duration`. ([#91154](https://github.com/kubernetes/kubernetes/pull/91154), [@liggitt](https://github.com/liggitt)) [SIG Auth and Cloud Provider]
- Support kubectl create deployment with replicas ([#91562](https://github.com/kubernetes/kubernetes/pull/91562), [@zhouya0](https://github.com/zhouya0)) [SIG CLI]
- The RotateKubeletClientCertificate feature gate has been promoted to GA, and the kubelet --feature-gate RotateKubeletClientCertificate parameter will be removed in 1.20. ([#91780](https://github.com/kubernetes/kubernetes/pull/91780), [@liggitt](https://github.com/liggitt)) [SIG Auth and Node]
- The metric label name of `kubernetes_build_info` has been updated from `camel case` to `snake case`:
- gitVersion --> git_version
- gitCommit --> git_commit
- gitTreeState --> git_tree_state
- buildDate --> build_date
- goVersion --> go_version
This change happens in `kube-apiserver`、`kube-scheduler`、`kube-proxy` and `kube-controller-manager`. ([#91805](https://github.com/kubernetes/kubernetes/pull/91805), [@RainbowMango](https://github.com/RainbowMango)) [SIG API Machinery, Cluster Lifecycle and Instrumentation]
- `EventRecorder()` is exposed to `FrameworkHandle` interface so that scheduler plugin developers can choose to log cluster-level events. ([#92010](https://github.com/kubernetes/kubernetes/pull/92010), [@Huang-Wei](https://github.com/Huang-Wei)) [SIG Scheduling]
### Bug or Regression
- Azure: set dest prefix and port for IPv6 inbound security rule ([#91831](https://github.com/kubernetes/kubernetes/pull/91831), [@aramase](https://github.com/aramase)) [SIG Cloud Provider]
- Fix etcd version migration script in etcd image. ([#91925](https://github.com/kubernetes/kubernetes/pull/91925), [@wenjiaswe](https://github.com/wenjiaswe)) [SIG API Machinery]
- Fix issues when supported huge page sizes changes ([#80831](https://github.com/kubernetes/kubernetes/pull/80831), [@odinuge](https://github.com/odinuge)) [SIG Node and Testing]
- Fix kubectl describe output format for empty annotations. ([#91405](https://github.com/kubernetes/kubernetes/pull/91405), [@iyashu](https://github.com/iyashu)) [SIG CLI]
- Fixed an issue that a Pod's nominatedNodeName cannot be cleared upon node deletion. ([#91750](https://github.com/kubernetes/kubernetes/pull/91750), [@Huang-Wei](https://github.com/Huang-Wei)) [SIG Scheduling and Testing]
- Fixed several bugs involving the IPFamily field when creating or updating services
in clusters with the IPv6DualStack feature gate enabled.
Beware that the behavior of the IPFamily field is strange and inconsistent and will
likely be changed before the dual-stack feature goes GA. Users should treat the
field as "write-only" for now and should not make any assumptions about a service
based on its current IPFamily value. ([#91400](https://github.com/kubernetes/kubernetes/pull/91400), [@danwinship](https://github.com/danwinship)) [SIG Apps and Network]
- Kube-apiserver: fixes scale subresource patch handling to avoid returning unnecessary 409 Conflict error to clients ([#90342](https://github.com/kubernetes/kubernetes/pull/90342), [@liggitt](https://github.com/liggitt)) [SIG Apps, Autoscaling and Testing]
- Kube-up: fixes setup of validating admission webhook credential configuration ([#91995](https://github.com/kubernetes/kubernetes/pull/91995), [@liggitt](https://github.com/liggitt)) [SIG Cloud Provider and Cluster Lifecycle]
- Kubeadm: Add retries for kubeadm join / UpdateStatus to make update status more resilient by adding a retry loop to this operation ([#91952](https://github.com/kubernetes/kubernetes/pull/91952), [@xlgao-zju](https://github.com/xlgao-zju)) [SIG Cluster Lifecycle]
- On AWS nodes with multiple network interfaces, kubelet should now more reliably report addresses from secondary interfaces. ([#91889](https://github.com/kubernetes/kubernetes/pull/91889), [@anguslees](https://github.com/anguslees)) [SIG Cloud Provider]
- Resolve regression in metadata.managedFields handling in create/update/patch requests not using server-side apply ([#91690](https://github.com/kubernetes/kubernetes/pull/91690), [@apelisse](https://github.com/apelisse)) [SIG API Machinery and Testing]
### Other (Cleanup or Flake)
- Deprecate the `--target-ram-md` flags that is no longer used for anything. ([#91818](https://github.com/kubernetes/kubernetes/pull/91818), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery]
- Replace framework.Failf with ExpectNoError ([#91811](https://github.com/kubernetes/kubernetes/pull/91811), [@lixiaobing1](https://github.com/lixiaobing1)) [SIG Instrumentation, Storage and Testing]
- The Kubelet's `--experimental-allocatable-ignore-eviction` option is now marked as deprecated. ([#91578](https://github.com/kubernetes/kubernetes/pull/91578), [@knabben](https://github.com/knabben)) [SIG Node]
- Update corefile-migration library to 1.0.8 ([#91856](https://github.com/kubernetes/kubernetes/pull/91856), [@wawa0210](https://github.com/wawa0210)) [SIG Node]

## Changelog since v1.19.0-alpha.3
## Urgent Upgrade Notes
### (No, really, you MUST read this before you upgrade)
- ACTION REQUIRED : Switch core master base images (kube-controller-manager) from debian to distroless. If you need Flex Volumes support using scripts, please build your own image with required packages (like bash) ([#91329](https://github.com/kubernetes/kubernetes/pull/91329), [@dims](https://github.com/dims)) [SIG Cloud Provider, Release, Storage and Testing]
- Kubeadm: Move the "kubeadm init" phase "kubelet-start" later in the init workflow, after the "kubeconfig" phase. This makes kubeadm start the kubelet only after the KubeletConfiguration component config file (/var/lib/kubelet/config.yaml) is generated and solves a problem where init systems like OpenRC cannot crashloop the kubelet service. ([#90892](https://github.com/kubernetes/kubernetes/pull/90892), [@xphoniex](https://github.com/xphoniex)) [SIG Cluster Lifecycle]

## Changelog since v1.19.0-alpha.2
## Urgent Upgrade Notes
### (No, really, you MUST read this before you upgrade)
- Kubeadm does not set the deprecated '--cgroup-driver' flag in /var/lib/kubelet/kubeadm-flags.env, it will be set in the kubelet config.yaml. If you have this flag in /var/lib/kubelet/kubeadm-flags.env or /etc/default/kubelet (/etc/sysconfig/kubelet for RPMs) please remove it and set the value using KubeletConfiguration ([#90513](https://github.com/kubernetes/kubernetes/pull/90513), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]
- Kubeadm respects resolvConf value set by user even if systemd-resolved service is active. kubeadm no longer sets the flag in '--resolv-conf' in /var/lib/kubelet/kubeadm-flags.env. If you have this flag in /var/lib/kubelet/kubeadm-flags.env or /etc/default/kubelet (/etc/sysconfig/kubelet for RPMs) please remove it and set the value using KubeletConfiguration ([#90394](https://github.com/kubernetes/kubernetes/pull/90394), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]

## Changelog since v1.19.0-alpha.1
## Urgent Upgrade Notes
### (No, really, you MUST read this before you upgrade)
- Kubeadm now respects user specified etcd versions in the ClusterConfiguration and properly uses them. If users do not want to stick to the version specified in the ClusterConfiguration, they should edit the kubeadm-config config map and delete it. ([#89588](https://github.com/kubernetes/kubernetes/pull/89588), [@rosti](https://github.com/rosti)) [SIG Cluster Lifecycle]

- Kubeadm: during 'upgrade apply', if the kube-proxy ConfigMap is missing, assume that kube-proxy should not be upgraded. Same applies to a missing kube-dns/coredns ConfigMap for the DNS server addon. Note that this is a temporary workaround until 'upgrade apply' supports phases. Once phases are supported the kube-proxy/dns upgrade should be skipped manually.

([#89902](https://github.com/kubernetes/kubernetes/pull/89902), [@wojtek-t](https://github.com/wojtek-t)) [SIG Cloud Provider, Network and Scalability]
- If firstTimestamp is not set use eventTime when printing event ([#89999](https://github.com/kubernetes/kubernetes/pull/89999), [@soltysh](https://github.com/soltysh)) [SIG CLI]
- If we set parameter cgroupPerQos=false and cgroupRoot=/docker，this function will retrun nodeAllocatableRoot=/docker/kubepods, it is not right, the correct return should be /docker.
cm.NodeAllocatableRoot(s.CgroupRoot, s.CgroupDriver)
kubeDeps.CAdvisorInterface, err = cadvisor.New(imageFsInfoProvider, s.RootDirectory, cgroupRoots, cadvisor.UsingLegacyCadvisorStats(s.ContainerRuntime, s.RemoteRuntimeEndpoint))
the above function，as we use cgroupRoots to create cadvisor interface，the wrong parameter cgroupRoots will lead eviction manager not to collect metric from /docker, then kubelet frequently print those error：
E0303 17:25:03.436781 63839 summary_sys_containers.go:47] Failed to get system container stats for "/docker": failed to get cgroup stats for "/docker": failed to get container info for "/docker": unknown container "/docker"

- In the kubelet resource metrics endpoint at /metrics/resource, change the names of the following metrics:
- node_cpu_usage_seconds --> node_cpu_usage_seconds_total
- container_cpu_usage_seconds --> container_cpu_usage_seconds_total
This is a partial revert of [#86282](https://github.com/kubernetes/kubernetes/pull/86282), which was added in 1.18.0, and initially removed the _total suffix ([#89540](https://github.com/kubernetes/kubernetes/pull/89540), [@dashpole](https://github.com/dashpole)) [SIG Instrumentation and Node]
- Kube-apiserver: multiple comma-separated protocols in a single X-Stream-Protocol-Version header are now recognized, in addition to multiple headers, complying with RFC2616 ([#89857](https://github.com/kubernetes/kubernetes/pull/89857), [@tedyu](https://github.com/tedyu)) [SIG API Machinery]
- Kubeadm increased to 5 minutes its timeout for the TLS bootstrapping process to complete upon join ([#89735](https://github.com/kubernetes/kubernetes/pull/89735), [@rosti](https://github.com/rosti)) [SIG Cluster Lifecycle]
- Kubeadm: during join when a check is performed that a Node with the same name already exists in the cluster, make sure the NodeReady condition is properly validated ([#89602](https://github.com/kubernetes/kubernetes/pull/89602), [@kvaps](https://github.com/kvaps)) [SIG Cluster Lifecycle]
- Kubeadm: fix a bug where post upgrade to 1.18.x, nodes cannot join the cluster due to missing RBAC ([#89537](https://github.com/kubernetes/kubernetes/pull/89537), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]

- Kubectl azure authentication: fixed a regression in 1.18.0 where "spn:" prefix was unexpectedly added to the `apiserver-id` configuration in the kubeconfig file ([#89706](https://github.com/kubernetes/kubernetes/pull/89706), [@weinong](https://github.com/weinong)) [SIG API Machinery and Auth]
- Restore the ability to `kubectl apply --prune` without --namespace flag. Since 1.17, `kubectl apply --prune` only prunes resources in the default namespace (or from kubeconfig) or explicitly specified in command line flag. But this is s breaking change from kubectl 1.16, which can prune resources in all namespace in config file. This patch restores the kubectl 1.16 behaviour. ([#89551](https://github.com/kubernetes/kubernetes/pull/89551), [@tatsuhiro-t](https://github.com/tatsuhiro-t)) [SIG CLI and Testing]
- Restores priority of static control plane pods in the cluster/gce/manifests control-plane manifests ([#89970](https://github.com/kubernetes/kubernetes/pull/89970), [@liggitt](https://github.com/liggitt)) [SIG Cluster Lifecycle and Node]
- Service account tokens bound to pods can now be used during the pod deletion grace period. ([#89583](https://github.com/kubernetes/kubernetes/pull/89583), [@liggitt](https://github.com/liggitt)) [SIG Auth]
- Sync LB backend nodes for Service Type=LoadBalancer on Add/Delete node events. ([#81185](https://github.com/kubernetes/kubernetes/pull/81185), [@andrewsykim](https://github.com/andrewsykim)) [SIG Apps and Network]
### Other (Cleanup or Flake)

- Changes not found message when using `kubectl get` to retrieve not namespaced resources ([#89861](https://github.com/kubernetes/kubernetes/pull/89861), [@rccrdpccl](https://github.com/rccrdpccl)) [SIG CLI]
- Node ([#76443](https://github.com/kubernetes/kubernetes/pull/76443), [@mgdevstack](https://github.com/mgdevstack)) [SIG Architecture, Network, Node, Testing and Windows]
- Reduce event spam during a volume operation error. ([#89794](https://github.com/kubernetes/kubernetes/pull/89794), [@msau42](https://github.com/msau42)) [SIG Storage]
- The PR adds functionality to generate events when a PV or PVC processing encounters certain failures. The events help users to know the reason for the failure so they can take necessary recovery actions. ([#89845](https://github.com/kubernetes/kubernetes/pull/89845), [@yuga711](https://github.com/yuga711)) [SIG Apps]
- The PodShareProcessNamespace feature gate has been removed, and the PodShareProcessNamespace is unconditionally enabled. ([#90099](https://github.com/kubernetes/kubernetes/pull/90099), [@tanjunchen](https://github.com/tanjunchen)) [SIG Node]

## Changelog since v1.19.0-alpha.0
## Urgent Upgrade Notes
### (No, really, you MUST read this before you upgrade)
- The StreamingProxyRedirects feature and `--redirect-container-streaming` flag are deprecated, and will be removed in a future release. The default behavior (proxy streaming requests through the kubelet) will be the only supported option.
If you are setting `--redirect-container-streaming=true`, then you must migrate off this configuration. The flag will no longer be able to be enabled starting in v1.20. If you are not setting the flag, no action is necessary. ([#88290](https://github.com/kubernetes/kubernetes/pull/88290), [@tallclair](https://github.com/tallclair)) [SIG API Machinery and Node]
- `kubectl` no longer defaults to `http://localhost:8080`. If you own one of these legacy clusters, you are *strongly- encouraged to secure your server. If you cannot secure your server, you can set `KUBERNETES_MASTER` if you were relying on that behavior and you're client-go user. Set `--server`, `--kubeconfig` or `KUBECONFIG` to make it work in `kubectl`.
