Changelog since v1.26.0

Changes by Kind

API Change

• The list-type of the alpha resourceClaims field introduced to Pods in 1.26.0 was modified from "set" to "map", resolving an incompatibility with use of this schema in CustomResourceDefinitions and with server-side apply. (#114617, @JoelSpeed) [SIG API Machinery]

Feature

• Kubernetes is now built with Go 1.19.5 (#115014, @cpanato) [SIG Release and Testing]

Failing Test

• Deflake a preemption test that may patch Nodes incorrectly. (#114350, @Huang-Wei) [SIG Scheduling and Testing]

Bug or Regression

• Client-go: fixes potential data races retrying requests using a custom io.Reader body; with this fix, only requests with no body or with string / []byte / runtime.Object bodies can be retried (#113933, @liggitt) [SIG API Machinery]
• Do not include preemptor pod metadata in the event message (#114946, @mimowo) [SIG Scheduling]
• Do not include preemptor pod metadata in the message of DisruptionTarget condition (#114945, @mimowo) [SIG Scheduling]
• Failed pods associated with a job with parallelism = 1 are recreated by the job controller honoring exponential backoff delay again. However, for jobs with parallelism > 1, pods might be created without exponential backoff delay. (#115027, @nikhita) [SIG Apps]
• Fix a regression that the scheduler always goes through all Filter plugins. (#114524, @Huang-Wei) [SIG Scheduling]
• Fix bug in CRD Validation Rules (beta) and ValidatingAdmissionPolicy (alpha) where all admission requests could result in internal error: runtime error: index out of range [3] with length 3 evaluating rule: <rule name> under certain circumstances. (#114861, @jpbetz) [SIG API Machinery, Auth and Cloud Provider]
• Fix clearing of rate-limiter for the queue of checks for cleaning stale pod disruption conditions.
  The bug could result in the PDB synchronization updates firing too often or the pod disruption cleanups taking too long to happen. (#114780, @mimowo) [SIG Apps]
• Fixed DaemonSet to update the status even if it fails to create a pod. (#114819, @gjkim42) [SIG Apps and Testing]
• Fixes stuck apiserver if an aggregated apiservice returned 304 Not Modified for aggregated discovery information (#114459, @alexzielenski) [SIG API Machinery]
• Fixing issue in Winkernel Proxier - Unexpected active TCP connection drops while horizontally scaling the endpoints for a LoadBalancer Service with External Traffic Policy: Local (#114038, @princepereira) [SIG Network]
• Fixing issue with Winkernel Proxier - No ingress load balancer rules with endpoints to support load balancing when all the endpoints are terminating. (#114453, @princepereira) [SIG Network and Windows]
• Optimizing loadbalancer creation with the help of attribute Internal Traffic Policy: Local (#114468, @princepereira) [SIG Network]

Changelog since v1.25.0

Urgent Upgrade Notes

(No, really, you MUST read this before you upgrade)

• Deprecated beta APIs scheduled for removal in v1.26 are no longer served. See https://kubernetes.io/docs/reference/using-api/deprecation-guide/#v1-26 for more information. (#111973, @liggitt)
• The in-tree cloud provider for OpenStack (and the cinder volume provider) has been removed. Please use the external cloud provider and csi driver from cloud-provider-openstack instead. (#67782, @dims)

Changes by Kind

Deprecation

• CLI flag pod-eviction-timeout is deprecated and will be removed together with enable-taint-manager in v1.27. (#113710, @kerthcet)
• Kube-apiserver: the unused --master-service-namespace flag was deprecated and will be removed in v1.27. (#112797, @SataQiu)
• The gcp and azure auth plugins have been removed from client-go and kubectl. See kubelogin and Kubectl Auth Changes in GKE for details about the cloud-specific replacements. (#112341, @enj)

API Change

• 'A new preEnqueue extension point was added to scheduler's component config
  v1beta2/v1beta3/v1.'
  (#113275, @Huang-Wei)
• 'Added a ResourceClaim API (in the resource.k8s.io/v1alpha1 API group and
  behind the DynamicResourceAllocation feature gate).
  The new API is now more flexible than the existing Device Plugins feature of Kubernetes because it
  allows Pods to request (claim) special kinds of resources, which can be available at node level, cluster
  level, or following any other model you implement.' (#111023, @pohly)
• 'Container preStop and postStart lifecycle handlers using httpGet now
  honor the specified scheme and headers fields. This enables setting custom
  headers and changing the scheme to HTTPS, consistent with container
  startup/readiness/liveness probe capabilities. Lifecycle handlers configured
  with scheme: HTTPS that encounter errors indicating the endpoint is actually
  using HTTP fall back to making the request over HTTP for compatibility with
  previous releases. When this happens, a LifecycleHTTPFallback event is recorded
  in the namespace of the pod and a kubelet_lifecycle_handler_http_fallbacks_total
  metric in the kubelet is incremented. Cluster administrators can opt out of the
  expanded lifecycle handler capabilities by setting
  --feature-gates=ConsistentHTTPGetHandlers=false in kubelet.'
  (#86139, @jasimmons)
• 'Graduated JobTrackingWithFinalizers to stable.
  Jobs created before the feature was enabled are still tracked without finalizers.
  Jobs tracked with finalizers have the annotation batch.kubernetes.io/job-tracking.
  If the annotation is present and the user attempts to remove it, the control plane adds it back.
  The annotation batch.kubernetes.io/job-tracking is now deprecated.
  The control plane will ignore it and stop adding it for new Jobs in v1.27.' (#113510, @alculquicondor)
• 'Kubelet added the following Pod failure conditions:
• DisruptionTarget (graceful node shutdown, node pressure eviction)' (#112360, @mimowo)
• 'Priority and Fairness has introduced a new feature called borrowing that allows an API priority level
  to borrow a number of seats from other priority level(s). As a cluster operator, you can enable borrowing
  for a certain priority level configuration object via the two newly introduced fields lendablePercent, and
  borrowingLimitPercent located under the .spec.limited field of the designated priority level.
  This change added the following metrics:
  • apiserver_flowcontrol_nominal_limit_seats: Nominal number of execution seats configured for each priority level
  • apiserver_flowcontrol_lower_limit_seats: Configured lower bound on number of execution seats available to each priority level
  • apiserver_flowcontrol_upper_limit_seats: Configured upper bound on number of execution seats available to each priority level
  • apiserver_flowcontrol_demand_seats: Observations, at the end of every nanosecond, of (the number of seats each priority level could use) / (nominal number of seats for that level)
  • apiserver_flowcontrol_demand_seats_high_watermark: High watermark, over last adjustment period, of demand_seats
  • apiserver_flowcontrol_demand_seats_average: Time-weighted average, over last adjustment period, of demand_seats
  • apiserver_flowcontrol_demand_seats_stdev: Time-weighted standard deviation, over last adjustment period, of demand_seats
  • apiserver_flowcontrol_demand_seats_smoothed: Smoothed seat demands
  • apiserver_flowcontrol_target_seats: Seat allocation targets
  • apiserver_flowcontrol_seat_fair_frac: Fair fraction of server's concurrency to allocate to each priority level that can use it
  • apiserver_flowcontrol_current_limit_seats: current derived number of execution seats available to each priority level
    The possibility of borrowing means that the old metric apiserver_flowcontrol_request_concurrency_limit can no longer mean both the configured concurrency limit and the enforced concurrency limit. Henceforth it means the configured concurrency limit.' (#113485, @MikeSpreitzer)
• 'NodeInclusionPolicy in podTopologySpread plugin is now enabled by default.'
  (#113500, @kerthcet)
• 'PodDisruptionBudget now adds an alpha spec.unhealthyPodEvictionPolicy field.
  When the PDBUnhealthyPodEvictionPolicy feature-gate is enabled in kube-apiserver,
  setting this field to "AlwaysAllow" allows pods to be evicted if they do not
  have a ready condition, regardless of whether the PodDisruptionBudget is currently
  healthy.'
  (#113375, @atiratree)
• 'metav1.LabelSelectors specified in API objects are now validated to ensure
  they do not contain invalid label values that will error at time of use. Existing
  invalid objects can be updated, but new objects are required to contain valid
  label selectors.'
  (#113699, @liggitt)
• Add percentageOfNodesToScore as a scheduler profile level parameter to API version v1. When a profile percentageOfNodesToScore is set, it will override global percentageOfNodesToScore. (#112521, @yuanchen8911)
• Add auth API to get self subject attributes (new selfsubjectreviews API is added).
  The corresponding command for kubctl is provided - kubectl auth whoami. (#111333, @nabokihms) [SIG API Machinery, Auth, CLI and Testing]
• Added kubernetes_feature_enabled metric series to track whether each active feature gate is enabled. (#112690, @logicalhan)
• Added a --topology-manager-policy-options flag to the kubelet to support fine tuning the topology manager policies. The first policy option, prefer-closest-numa-nodes, allows these policies to favor sets of NUMA nodes with shorter distance between nodes when making admission decisions. (#112914, @PiotrProkop)
• Added a feature that allows a StatefulSet to start numbering replicas from an arbitrary non-negative ordinal, using the .spec.ordinals.start field. (#112744, @pwschuurman)
• Added a kube-proxy flag (--iptables-localhost-nodeports, default true) to allow disabling NodePort services on loopback addresses. Note: this only applies to iptables mode and ipv4. (#108250, @cyclinder)
• Added a new namespace alpha field to DataSourceRef field in PersistentVolumeClaim API. (#113186, @ttakahashi21)
• Aggregated discovery will be alpha and can be toggled with the AggregatedDiscoveryEndpoint feature flag. (#113171, @Jefftree)
• Clarified the CFS quota as 100ms in the code comments and set the minimum cpuCFSQuotaPeriod to 1ms to match Linux kernel expectations. (#112123, @paskal)
• Component-base: make the validation logic about LeaderElectionConfiguration consistent between component-base and client-go (#111758, @SataQiu) [SIG API Machinery and Scheduling]
• Deprecated the apiserver_request_slo_duration_seconds metric for v1.27 in favor of apiserver_request_sli_duration_seconds for naming consistency purposes with other SLI-specific metrics and to avoid any confusion between SLOs and SLIs. (#112679, @dgrisonnet)
• Enable the "Retriable and non-retriable pod failures for jobs" feature into beta. (#113360, @mimowo)
• Enabled kube-controller-manager to support '--concurrent-horizontal-pod-autoscaler-syncs' flag to set the number of horizontal pod autoscaler controller workers. (#108501, @zroubalik)
• Fixed spurious field is immutable errors validating updates to Event API objects via the events.k8s.io/v1 API. (#112183, @liggitt)
• Graduated ServiceInternalTrafficPolicy feature to GA. (#113496, @avoltz)
• In 'kube-proxy`: The "userspace" proxy mode (deprecated for over a year) is no
  longer supported on either Linux or Windows. Users should use "iptables" or "ipvs"
  on Linux, or "kernelspace" on Windows.
  (#112133, @knabben)
• Introduce v1beta3 for Priority and Fairness with the following changes to the API spec:
• rename 'assuredConcurrencyShares' (located under `spec.limited') to 'nominalConcurrencyShares'.
• apply strategic merge patch annotations to 'Conditions' of flowschemas and prioritylevelconfigurations. (#112306, @tkashem)
• Introduced v1alpha1 API for validating admission policies, enabling extensible admission control via CEL expressions (KEP 3488: CEL for Admission Control). To use, enable the ValidatingAdmissionPolicy feature gate and the admissionregistration.k8s.io/v1alpha1 API via --runtime-config. (#113314, @cici37)
• KMS: added validation for duplicate kms config name when auto reload is enabled. If you enabled automatic reload of encryption configuration with API server flag --encryption-provider-config-automatic-reload, ensure all the KMS provider names (v1 and v2) in the encryption configuration are unique. (#113697, @aramase)
• Kubelet external Credential Provider feature is moved to GA. Credential Provider Plugin and Credential Provider Config APIs updated from v1beta1 to v1 with no API changes. (#111616, @ndixita)
• Legacy klog flags are no longer available. Only -v and -vmodule are still supported. (#112120, @pohly) [SIG Architecture, CLI, Instrumentation, Node and Testing]
• Moved MixedProtocolLBService from beta to GA. (#112895, @janosi)
• New Pod API field .spec.schedulingGates is introduced to enable users to control when to mark a Pod as scheduling ready. (#113274, @Huang-Wei)
• 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, @haoruan)
• Removed feature gates ServiceLoadBalancerClass and ServiceLBNodePortControl. These feature gates were enabled (and locked) since v1.24. (#112577, @andrewsykim)
• Reverted regression that prevented client-go latency metrics to be reported with a template URL to avoid label cardinality. (#111752, @aanm)
• The EndpointSliceTerminatingCondition feature gate was graduated to GA. The gate is now locked and will be removed in v1.28. (#113351, @andrewsykim)
• DynamicKubeletConfig feature gate has been removed from the API server.
  Dynamic kubelet reconfiguration now can't be used even when older nodes are still
  attempting to rely on it. This is aligned with the Kubernetes version skew policy.
  (#112643, @SergeyKanzhelev)
• kubectl wait command with jsonpath flag will wait for target path until timeout.
  (#109525, @jonyhy96)

Feature

• 'Added selector validation to HorizontalPodAutoscaler: when multiple HPAs
  select the same set of Pods, scaling now will be disabled for those HPAs with
  the reason AmbiguousSelector. This change also covers a case when multiple HPAs
  point to the same deployment.'
  (#112011, @pbeschetnov)
• 'Pod Security admission: the pod-security warn level will now default to
  the enforce level.'
  (#113491, @tallclair)
• 'Promoted the APIServerIdentity feature to Beta. By default, each kube-apiserver
  will now create a Lease in the kube-system namespace. These lease objects can
  be used to identify the number of active API servers in the cluster, and may also
  be used for future features such as the Storage Version API.'
  (#113629, @andrewsykim)
• 'The iptables kube-proxy backend now process service/endpoint changes
  more efficiently in very large clusters.' (#110268, @danwinship)
• 'CSIMigrationvSphere was upgraded to GA and locked to true. Do not upgrade to K8s
  1.26 if you need Windows, or XFS, or raw block support until vSphere CSI Driver
  adds support for them in a version post v2.7.x.'
  (#113336, @divyenpatel)
• 'DelegateFSGroupToCSIDriver feature is GA.'
  (#113225, @bertinatto)
• 'NodeOutOfServiceVolumeDetach is now beta.'
  (#113511, @xing-yang)
• 'RetroactiveDefaultStorageClass feature is now beta.'
  (#113329, @RomanBednar)
• 'registered_metric_total will now report the number of metrics broken down by
  stability level and deprecated version.'
  (#112907, @logicalhan)
• 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, @shyamjvs)
• A new pod_status_sync_duration_seconds histogram is reported at alpha metrics stability that estimates how long the Kubelet takes to write a pod status change once it is detected. (#107896, @smarterclayton) [SIG Apps, Architecture, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Network, Node, Release, Scheduling, Storage and Testing]
• API Server Tracing now includes a variety of new spans and span events. (#113172, @dashpole) [SIG API Machinery, Architecture, Auth, Instrumentation, Network, Node and Scheduling]
• API Server tracing now includes the latency of authorization, priorityandfairness, impersonation, audit, and authentication filters. (#113217, @dashpole)
• API Server tracing root span name for opentelemetry is changed from KubernetesAPI to HTTP GET. (#112545, @dims)
• Added --disable-compression flag to kubectl (default = false). When true, it opts out of response compression for all requests to the apiserver.

• Added new metric job_controller_terminated_pods_tracking_finalizer which can be used to monitor whether the job controller is removing Pod finalizers from terminated Pods after accounting them in Job status. (#113176, @alculquicondor)
• Added publishing events when enabling/disabling TopologyAwareHints. (#113544, @LiorLieberman)
• Added reconstruction of SELinux mount context after kubelet restart. Feature SELinuxMountReadWriteOncePod is now fully implemented and kubelet does not lose its cache of SELinux contexts after kubelet process restart. (#113596, @jsafrane)
• Added support for Evented PLEG feature gate. (#111384, @harche)
• Added the metric pod_start_sli_duration_seconds to kubelet. (#111930, @azylinski)
• Added validation for the --container-runtime-endpoint flag of kubelet to be non-empty. (#112542, @astraw99)
• Adds alpha --output plaintext protected by environment variable KUBECTL_EXPLAIN_OPENAPIV3 (#113146, @alexzielenski) [SIG CLI]
• Adds metrics force_delete_pods_total and force_delete_pod_errors_total in the Pod GC Controller. (#113519, @xing-yang) [SIG Apps]

• If ComponentSLIs feature gate is enabled, then /metrics/slis now becomes available on cloud-controller-manager allowing you to scrape health check metrics. (#113340, @Richabanker)
• If more than one StorageClass is designated as default (via the "storageclass.kubernetes.io/is-default-class" annotation), choose the newest one instead of throwing an error. (#110559, @danishprakash)
• In client-go SharedInformerFactory will now support waiting for goroutines during shutdown.
  (#112200, @pohly)
• In kubeadm, command kubeadm join phase control-plane-prepare certs now supports to run with dry-run mode on it's own. (#113005, @chendave)
• 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, @shyamjvs)
• Kubeadm: added show-join-command 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, @SataQiu)

• Switched kubectl to use github.com/russross/blackfriday/v2 (#112731, @pacoxu)
• The ExpandedDNSConfig feature has graduated to beta and is enabled by default. Note that this feature requires container runtime support. (#112824, @gjkim42) [SIG Network and Testing]
• The LegacyServiceAccountTokenNoAutoGeneration feature gate was promoted to GA. (#112838, @zshihang)
• The ProxyTerminatingEndpoints feature is now Beta and enabled by default. When enabled, kube-proxy will attempt to route traffic to terminating pods when the traffic policy is Local and there are only terminating pods remaining on a node. (#113363, @andrewsykim)
• 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, @sanposhiho) [SIG Instrumentation and Scheduling]
• Updated cAdvisor to v0.46.0. (#113769, @bobbypage)
• Updated the Lease identity naming format for the APIServerIdentity feature to use a persistent name. (#113307, @andrewsykim)
• When ComponentSLIs feature gate is enabled, /metrics/slis becomes available on kube-scheduler, allowing you to scrape health check metrics. (#113026, @Richabanker)
• When ComponentSLIs feature gate is enabled, then /metrics/slis becomes available on kube-proxy allowing you to scrape health check metrics. (#113057, @Richabanker)
• When ComponentSLIs feature gate is enabled, then /metrics/slis becomes available on kube-controller-manager, allowing you to scrape health check metrics. (#112978, @logicalhan)
• When the alpha LegacyServiceAccountTokenTracking feature gate is enabled, secret-based service account tokens will have a kubernetes.io/legacy-token-last-used applied to them containing the date they were last used. (#108858, @zshihang) [SIG API Machinery, Auth and Testing]

  enabled now removed in v1.26.
  (#112386, @Shubham82)
• kubectl config view now automatically redacts any secret fields marked with a datapolicy tag. (#109189, @mpuckett159)

Documentation

• Clarified the default CFS quota period as being 100µs and not 100ms. (#111554, @paskal) [SIG Node]

Bug or Regression

• Added back unused flags on kubectl run command, which did not go through the required deprecation period before being removed. (#112243, @brianpursley)
• Added support for RSA and ECDSA format keys in preflight check on kubeadm. (#112508, @SataQiu)
• Allowed Label section in vSphere e2e cloud provider configuration. (#112427, @gnufied)
• Apiserver /healthz/etcd endpoint rate limits the number of forwarded health check requests to the etcd backends, answering with the last known state if the rate limit is exceeded. The rate limit is based on 1/2 of the timeout configured, with no burst allowed. (#112046, @aojea)
• Apiserver: used the correct error when logging errors updating managedFields. (#113711, @andrewsykim)
• Avoided propagating hosts search . into containers in /etc/resolv.conf. (#112157, @dghubble)

• Fixed that disruption controller used to change the status of a stale disruption condition after 2 min when the PodDisruptionConditions feature gate is enabled. (#113580, @mimowo)
• Fixed the PodAndContainerStatsFromCRI feature, instead of supplementing with stats from cAdvisor. (#113291, @mengjiao-liu)
• Fixed the occasional double-counting of the job_finished_total metric. (#112948, @mimowo)
• For kubectl, --server-side now migrates ownership of all fields used by client-side-apply to the specified --fieldmanager. This prevents fields previously specified using kubectl from being able to live outside of server-side-apply's management and become undeleteable. (#112905, @alexzielenski)
• 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 change modified that behavior to ensure it is only called once per volume per node. (#112403, @akankshakumari393)
• Improved kubectl display of invalid request errors returned by the API server. (#112150, @liggitt)
• In 'kube-apiserver,x-kubernetes-list-type` validation is now enforced when updating status of custom resources.' (#111866, @pacoxu)
• In kube-apiserver, custom resources can now be specified in the --encryption-provider-config file and can be encrypted in etcd. (#113015, @ritazh)

• Kube-apiserver: redirects from backend API servers are no longer followed when checking availability with requests to /apis/$group/$version (#112772, @liggitt) [SIG API Machinery and Testing]
• Kube-apiserver: resolved a regression that treated 304 Not Modified responses from aggregated API servers as internal errors. (#112526, @liggitt)
• Kube-proxy no longer falls back from ipvs mode to iptables mode if you ask it to do ipvs but the system is not correctly configured. Instead, it will just exit with an error. (#111806, @danwinship) [SIG Network]
• Kube-scheduler: added taints filtering logic consistent with TaintToleration plugin for PodTopologySpread plugin. (#112357, @SataQiu)

• Kubectl: fixed a bug where kubectl convert did not pick the right API version (#112700, @SataQiu)
• Kubelet now cleans up the Node's cloud node IP annotation correctly if you
  stop using --node-ip. (In particular, this fixes the problem where people who
  were unnecessarily using --node-ip with an external cloud provider in 1.23,
  and then running into problems with 1.24, could not fix the problem by just
  removing the unnecessary --node-ip from the kubelet arguments, because
  that wouldn't remove the annotation that caused the problems.) (#112184, @danwinship) [SIG Network and Node]
• Kubelet: Fixed a startup crash in devicemanager. (#113021, @rphillips)
• Kubelet: fixed log spam from kubelet_getters.go Path does not exist. (#112650, @rphillips)
• Kubelet: fixed nil pointer in reflector start for standalone mode. (#113501, @pacoxu)
• Kubelet: when there are multi option lines in /etc/resolv.conf, merge all options into one line in a pod with the Default DNS policy. (#112414, @pacoxu) [SIG Network and Node]
• 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 displayed as the correct resource and group, instead of *unstructured.Unstructured. (#111807, @ncdc)
• Moved LocalStorageCapacityIsolationFSQuotaMonitoring back to Alpha. (#112076, @rphillips)
• NOTE (#113749, @jpbetz) [SIG API Machinery]
• Nested MountPoints are now grouped correctly on all cases. (#112571, @claudiubelu)
• Pod failed in scheduling due to expected error will be updated with the reason of SchedulerError rather than Unschedulable. (#111999, @kerthcet)
• Pod logs using --timestamps are not broken up with timestamps anymore. (#113481, @rphillips)
• Removed of raising an error when setting an annotation with the same value, just ignore it. (#109505, @zigarn)
• Resolved an issue that caused winkernel proxier to treat stale VIPs as valid. (#113521, @daschott)
• The ResourceVersion returned in objects from delete responses is now consistent with the ResourceVersion contained in the delete watch event. (#113369, @wojtek-t)
• The kube-scheduler and kube-controller-manager now use server side apply to set conditions related to pod disruption. (#113304, @mimowo) [SIG API Machinery, Apps and Scheduling]
• The errors in k8s.io/apimachinery/pkg/api/meta now support for the stdlibs errors.Is matching, including when wrapped. (#111808, @alvaroaleman)
• The metrics etcd_request_duration_seconds and etcd_bookmark_counts now differentiate by group resource instead of object type, allowing unique entries per CustomResourceDefinition, instead of grouping them all under *unstructured.Unstructured. (#112042, @ncdc)
• The pod admission error message was improved for usability. (#112644, @vitorfhc) [SIG Node]
• The time duration of a failed or unschedulable scheduling attempt will be longer, it
  now includes the time duration of the unreserve operation. (#113113, @kerthcet)

• Updated creation of LoadBalancer services, for there to be fewer AWS security group rules in most cases. (#112267, @sjenning)
• Updated the system-validators library to v1.8.0 (#112026, @pacoxu)
• Updates golang.org/x/text`` tov0.3.8`` to fix CVE-2022-32149 (#112989, @ameukam)
• Volume mount cleanup now considers only plugin directory and not the entire kubelet root (#112607, @mattcary)
• kubectl now escapes terminal special characters in output. This fixes CVE-2021-25743.

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. (#112008, @pacoxu)
• Kubeadm: removed the usage of the --container-runtime=remote flag for the kubelet during kubeadm init/join/upgrade. The flag value remote had been the only possible value since dockershim was removed from the kubelet. (#112000, @pacoxu)

• Refactored test/e2e/framework so that the core framework is smaller. Optional functionality like resource monitoring, log size monitoring, metrics gathering and debug information dumping must be imported by specific e2e test suites. Init packages are provided which can be imported to re-enable the functionality that traditionally was in the core framework. If you have code that no longer compiles because of this PR, you can use the script from a commit message to update that code. (#112043, @pohly)

Changelog since v1.26.0-rc.0

Changes by Kind

Bug or Regression

• Fix endpoint reconciler not being able to delete the apiserver lease on shutdown (#114122, @aojea) [SIG API Machinery]
• Fixed a bug that resulted in "grpc: the client connection is closing" errors shortly after the Kubernetes API server automatically reloaded its encryption-at-rest config due to an observed change to the file. This bug was only encountered when the --encryption-provider-config-automatic-reload flag was set to true. (#113955, @enj) [SIG API Machinery, Auth and Testing]
• When the feature gates PodDisruptionConditions and JobPodFailurePolicy are both enabled,
  the Job controller now does not consider a terminating Pod (a pod that has a .metadata.deletionTimestamp)
  as a failure until that Pod is terminal (its .status.phase is Failed or Succeeded).

However, the Job controller creates a replacement Pod as soon as the termination becomes apparent.
Once the pod terminates, the Job controller evaluates .backoffLimit and .podFailurePolicy for the
relevant Job, taking this now-terminated Pod into consideration.

This behavior is limited to Jobs with .spec.podFailurePolicy set, and only when those two feature
gates are both enabled.
If either of these requirements is not satisfied, the Job controller counts a terminating Pod as an immediate
failure, even if that Pod later terminates with phase: "Succeeded". (#113860, @alculquicondor) [SIG Apps]

Changelog since v1.26.0-beta.0

Changes by Kind

API Change

• Add a ResourceClaim API (in the resource.k8s.io/v1alpha1 API group and
  behind the DynamicResourceAllocation feature gate).
  The new API is more flexible than the existing Device Plugins feature of Kubernetes because it
  allows Pods to request (claim) special kinds of resources, which can be available at node level, cluster
  level, or following any other model you implement. (#111023, @pohly) [SIG API Machinery, Apps, Architecture, Auth, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Node, Release, Scheduling, Storage and Testing]
• PodDisruptionBudget adds an alpha spec.unhealthyPodEvictionPolicy field. When the PDBUnhealthyPodEvictionPolicy feature-gate is enabled in kube-apiserver, setting this field to "AlwaysAllow" allows pods to be evicted if they do not have a ready condition, regardless of whether the PodDisruptionBudget is currently healthy. (#113375, @atiratree) [SIG API Machinery, Apps, Auth and Testing]

Feature

• Promote kubectl alpha events to kubectl events (#113819, @soltysh) [SIG CLI and Testing]

Bug or Regression

• Known issue: Job field .spec.podFailurePolicy.rules[*].onExitCode might be ignored if the Pod is deleted before it terminates. (#113856, @alculquicondor) [SIG Apps]

Changelog since v1.26.0-alpha.3

Changes by Kind

Deprecation

• CLI flag pod-eviction-timeout is deprecated and will be removed together with enable-taint-manager in v1.27. (#113710, @kerthcet) [SIG API Machinery and Apps]

API Change

• A new preEnqueue extension point is added to scheduler's component config v1beta2/v1beta3/v1. (#113275, @Huang-Wei) [SIG API Machinery, Apps, Instrumentation, Scheduling and Testing]
• Add a new namespace alpha field to dataSourceRef field in PersistentVolumeClaim API. (#113186, @ttakahashi21) [SIG API Machinery, Apps, Storage and Testing]
• Add a kube-proxy flag (--iptables-localhost-nodeports, default true) to allow disabling NodePort services on loopback addresses. Note: this only applies to iptables mode and ipv4. (#108250, @cyclinder) [SIG API Machinery, Cloud Provider, Network, Node, Scalability, Storage and Testing]
• Added a --topology-manager-policy-options flag to the kubelet to support fine tuning the topology manager policies. The first policy option, prefer-closest-numa-nodes, allows these policies to favor sets of NUMA nodes with shorter distance between nodes when making admission decisions. (#112914, @PiotrProkop) [SIG API Machinery and Node]
• Added a feature that allows a StatefulSet to start numbering replicas from an arbitrary non-negative ordinal, using the .spec.ordinals.start field. (#112744, @pwschuurman) [SIG API Machinery and Apps]
• Deprecate the apiserver_request_slo_duration_seconds metric for v1.27 in favor of apiserver_request_sli_duration_seconds for naming consistency purposes with other SLI-specific metrics and to avoid any confusion between SLOs and SLIs. (#112679, @dgrisonnet) [SIG API Machinery and Instrumentation]
• Enable the "Retriable and non-retriable pod failures for jobs" feature into beta (#113360, @mimowo) [SIG Apps, Auth, Node, Scheduling and Testing]
• Graduate JobTrackingWithFinalizers to stable.
  Jobs created before the feature was enabled are still tracked without finalizers.
  Users can choose to migrate jobs to tracking with finalizers by adding the annotation batch.kubernetes.io/job-tracking.
  If the annotation was already present and the user attempts to remove it, the control plane adds the annotation back. (#113510, @alculquicondor) [SIG API Machinery, Apps and Testing]
• Graduate ServiceInternalTrafficPolicy feature to GA (#113496, @avoltz) [SIG Apps and Network]
• If you enabled automatic reload of encryption configuration with API server flag --encryption-provider-config-automatic-reload, ensure all the KMS provider names (v1 and v2) in the encryption configuration are unique. (#113697, @aramase) [SIG API Machinery and Auth]
• Introduce v1alpha1 API for validating admission policies, enabling extensible admission control via CEL expressions (KEP 3488: CEL for Admission Control). To use, enable the ValidatingAdmissionPolicy feature gate and the admissionregistration.k8s.io/v1alpha1 API via --runtime-config. (#113314, @cici37) [SIG API Machinery, Auth, Cloud Provider and Testing]
• Kubelet adds the following pod failure conditions:
• DisruptionTarget (graceful node shutdown, node pressure eviction) (#112360, @mimowo) [SIG Apps, Node and Testing]
• Metav1.LabelSelectors specified in API objects are now validated to ensure they do not contain invalid label values that will error at time of use. Existing invalid objects can be updated, but new objects are required to contain valid label selectors. (#113699, @liggitt) [SIG API Machinery, Apps, Auth, Network and Storage]
• Moving MixedProtocolLBService from beta to GA (#112895, @janosi) [SIG Apps, Network and Testing]
• New Pod API field .spec.schedulingGates is introduced to enable users to control when to mark a Pod as scheduling ready. (#113274, @Huang-Wei) [SIG Apps, Scheduling and Testing]
• NodeInclusionPolicy in podTopologySpread plugin is enabled by default. (#113500, @kerthcet) [SIG API Machinery, Apps, Scheduling and Testing]
• Priority and Fairness has introduced a new feature called borrowing that allows an API priority level
  to borrow a number of seats from other priority level(s). As a cluster operator, you can enable borrowing
  for a certain priority level configuration object via the two newly introduced fields lendablePercent, and
  borrowingLimitPercent located under the .spec.limited field of the designated priority level.
  This PR adds the following metrics.
• apiserver_flowcontrol_nominal_limit_seats: Nominal number of execution seats configured for each priority level
• apiserver_flowcontrol_lower_limit_seats: Configured lower bound on number of execution seats available to each priority level
• apiserver_flowcontrol_upper_limit_seats: Configured upper bound on number of execution seats available to each priority level
• apiserver_flowcontrol_demand_seats: Observations, at the end of every nanosecond, of (the number of seats each priority level could use) / (nominal number of seats for that level)
• apiserver_flowcontrol_demand_seats_high_watermark: High watermark, over last adjustment period, of demand_seats
• apiserver_flowcontrol_demand_seats_average: Time-weighted average, over last adjustment period, of demand_seats
• apiserver_flowcontrol_demand_seats_stdev: Time-weighted standard deviation, over last adjustment period, of demand_seats
• apiserver_flowcontrol_demand_seats_smoothed: Smoothed seat demands
• apiserver_flowcontrol_target_seats: Seat allocation targets
• apiserver_flowcontrol_seat_fair_frac: Fair fraction of server's concurrency to allocate to each priority level that can use it
• apiserver_flowcontrol_current_limit_seats: current derived number of execution seats available to each priority level

The possibility of borrowing means that the old metric apiserver_flowcontrol_request_concurrency_limit can no longer mean both the configured concurrency limit and the enforced concurrency limit. Henceforth it means the configured concurrency limit. (#113485, @MikeSpreitzer) [SIG API Machinery and Testing]
- The EndpointSliceTerminatingCondition feature gate has graduated to GA. The gate is now locked and will be removed in v1.28. (#113351, @andrewsykim) [SIG API Machinery, Apps, Network and Testing]
- Yes, aggregated discovery will be alpha and can be toggled with the AggregatedDiscoveryEndpoint feature flag (#113171, @Jefftree) [SIG API Machinery, Apps, Architecture, Auth, Autoscaling, CLI, Cloud Provider, Cluster Lifecycle, Network, Node, Release, Scalability, Scheduling, Storage and Testing]

Changes by Kind

API Change

• Additional documentation e.g., KEPs (Kubernetes Enhancement Proposals), usage docs, etc.:

(#86139, @jasimmons) [SIG API Machinery, Apps, Architecture, Auth, Autoscaling, CLI, Contributor Experience, Instrumentation, Network, Node, Release, Scheduling, Storage and Testing]
- Add percentageOfNodesToScore as a scheduler profile level parameter to API version v1. If a profile percentageOfNodesToScore is set, it will override global percentageOfNodesToScore. (#112521, @yuanchen8911) [SIG API Machinery, Scheduling and Testing]
- Kube-controller-manager supports '--concurrent-horizontal-pod-autoscaler-syncs' flag to set the number of horizontal pod autoscaler controller workers. (#108501, @zroubalik) [SIG API Machinery, Apps and Autoscaling]
- Kube-proxy: The "userspace" proxy mode (deprecated for over a year) is no longer supported on either Linux or Windows. Users should use "iptables" or "ipvs" on Linux, or "kernelspace" on Windows. (#112133, @knabben) [SIG API Machinery, Network, Scalability, Testing and Windows]
- Kubectl wait command with jsonpath flag will wait for target path appear until timeout. (#109525, @jonyhy96) [SIG CLI and Testing]
- Kubelet external Credential Provider feature is moved to GA. Credential Provider Plugin and Credential Provider Config APIs updated from v1beta1 to v1 with no API changes. (#111616, @ndixita) [SIG API Machinery, Node, Scheduling and Testing]
- The DynamicKubeletConfig feature gate has been removed from the API server. Dynamic kubelet reconfiguration now cannot be used even when older nodes are still attempting to rely on it. This is aligned with the Kubernetes version skew policy. (#112643, @SergeyKanzhelev) [SIG API Machinery, Apps, Auth, Node and Testing]

Feature

• Added categories column to the kubectl api-resources command's wide output (-o wide).
  Added --categories flag to the kubectl api-resources command, which can be used to filter the output to show only resources belonging to one or more categories. (#111096, @brianpursley) [SIG CLI]
• Admission control plugin "DefaultStorageClass": If more than one StorageClass is designated as default (via the "storageclass.kubernetes.io/is-default-class" annotation), choose the newest one instead of throwing an error. (#110559, @danishprakash) [SIG Apps and Storage]
• Change preemption_victims metric bucket from LinearBuckets to ExponentialBuckets. (#112939, @lengrongfu) [SIG Instrumentation and Scheduling]
• Extend the job job_finished_total metric by newreason` label and introduce a new job metric to count pod failures
  handled by pod failure policy with respect to the action applied. (#113324, @mimowo) [SIG Apps and Testing]

Changelog since v1.26.0-alpha.1

Changes by Kind

Deprecation

• Kube-apiserver: the unused '--master-service-namespace' flag is deprecated and will be removed in v1.27. (#112797, @SataQiu) [SIG API Machinery]

API Change

• Add kubernetes_feature_enabled metric series to track whether each active feature gate is enabled. (#112690, @logicalhan) [SIG API Machinery, Architecture, Cluster Lifecycle, Instrumentation, Network, Node and Scheduling]
• Introduce v1beta3 for Priority and Fairness with the following changes to the API spec:
• rename 'assuredConcurrencyShares' (located under spec.limited') to 'nominalConcurrencyShares'
• apply strategic merge patch annotations to 'Conditions' of flowschemas and prioritylevelconfigurations (#112306, @tkashem) [SIG API Machinery and Testing]
• Legacy klog flags are no longer available. Only -v and -vmodule are still supported. (#112120, @pohly) [SIG Architecture, CLI, Instrumentation, Node and Testing]
• The feature gates ServiceLoadBalancerClass and ServiceLBNodePortControl have been removed. These feature gates were enabled (and locked) since v1.24. (#112577, @andrewsykim) [SIG Apps]

Feature

• A new --disable-compression flag has been added to kubectl (default = false). When true, it opts 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. (#112580, @shyamjvs) [SIG CLI and Testing]
• A new pod_status_sync_duration_seconds histogram is reported at alpha metrics stability that estimates how long the Kubelet takes to write a pod status change once it is detected. (#107896, @smarterclayton) [SIG Apps, Architecture, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Network, Node, Release, Scheduling, Storage and Testing]
• Added a new feature gate CELValidatingAdmission to enable expression validation for Admission Control. (#112792, @cici37) [SIG API Machinery]
• Added validation for the --container-runtime-endpoint flag of kubelet to be non-empty. (#112542, @astraw99) [SIG Node]
• Expose health check SLI metrics on "metrics/slis" for apiserver (#112741, @logicalhan) [SIG API Machinery, Architecture, Auth and Instrumentation]
• Kubeadm: sub-phases are now able to support the dry-run mode, e.g. kubeadm reset phase cleanup-node --dry-run (#112945, @chendave) [SIG Cluster Lifecycle]
• Kubeadm: support image repository format validation (#112732, @SataQiu) [SIG Cluster Lifecycle]
• Kubernetes is now built with Go 1.19.2 (#112900, @xmudrii) [SIG Release and Testing]
• Switch kubectl to use github.com/russross/blackfriday/v2 (#112731, @pacoxu) [SIG CLI]
• registered_metric_total now reports the number of metrics broken down by stability level and deprecated version (#112907, @logicalhan) [SIG Architecture and Instrumentation]

• Consider only plugin directory and not entire kubelet root when cleaning up mounts (#112607, @mattcary) [SIG Storage]
• Fix that pods running on nodes tainted with NoExecute continue to run when the PodDisruptionConditions feature gate is enabled (#112518, @mimowo) [SIG Apps and Auth]
• Fixes an issue in winkernel proxier that causes proxy rules to leak anytime service backends are modified. (#112837, @daschott) [SIG Network and Windows]
• Kube-apiserver: redirects from backend API servers are no longer followed when checking availability with requests to /apis/$group/$version (#112772, @liggitt) [SIG API Machinery and Testing]
• Kubeadm: fix a bug when performing validation on ClusterConfiguration networking fields (#112751, @SataQiu) [SIG Cluster Lifecycle]
• Kubelet now cleans up the Node's cloud node IP annotation correctly if you
  stop using --node-ip. (In particular, this fixes the problem where people who
  were unnecessarily using --node-ip with an external cloud provider in 1.23,
  and then running into problems with 1.24, could not fix the problem by just
  removing the unnecessary --node-ip from the kubelet arguments, because
  that wouldn't remove the annotation that caused the problems.) (#112184, @danwinship) [SIG Network and Node]
• Kubelet: Fix log spam from kubelet_getters.go "Path does not exist" (#112650, @rphillips) [SIG Node]
• Kubelet: when there are multi option lines in /etc/resolv.conf, merge all options into one line in a pod with the Default DNS policy. (#112414, @pacoxu) [SIG Network and Node]
• The pod admission error message was improved for usability. (#112644, @vitorfhc) [SIG Node]

Other (Cleanup or Flake)

• Adds a kubernetes_feature_enabled metric which will tell you if a feature is enabled. (#112652, @logicalhan) [SIG Architecture and Instrumentation]
• Introduce ComponentSLIs alpha feature-gate for component SLIs metrics endpoint. (#112884, @logicalhan) [SIG API Machinery]
• Lock ServerSideApply feature gate to true with the feature already being GA. (#112748, @wojtek-t) [SIG API Machinery, Apps, Instrumentation and Testing]
• PodOverhead feature gate was removed as the feature is in GA since 1.24 (#112579, @SergeyKanzhelev) [SIG Node and Scheduling]
• Reworded log message upon image garbage collection failure to be more clear. (#112631, @tzneal) [SIG Node]
• The IndexedJob and SuspendJob feature gates that graduated to GA in 1.24 and were unconditionally enabled have been removed in v1.26 (#112589, @SataQiu) [SIG Apps]
• The test/e2e/framework was refactored so that the core framework is smaller. Optional functionality like resource monitoring, log size monitoring, metrics gathering and debug information dumping must be imported by specific e2e test suites. Init packages are provided which can be imported to re-enable the functionality that traditionally was in the core framework. If you have code that no longer compiles because of this PR, you can use the script from a commit message to update that code.

• Updated cri-tools to [v1.25.0(https://github.com/kubernetes-sigs/cri-tools/releases/tag/v1.25.0) (#112058, @saschagrunert) [SIG Cloud Provider and Release]
