- CVE-2020-8559 (Medium): Privilege escalation from compromised node to cluster. See kubernetes#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, @tallclair) [SIG API Machinery]
-
CVE-2020-8557 (Medium): Node-local denial of service via container /etc/hosts file. See kubernetes#93032 for more details. (#92916, @joelsmith) [SIG Node]

Fixes a problem with 63-second or 1-second connection delays with some VXLAN-based network plugins which was first widely noticed in 1.16 (though some users saw it earlier than that, possibly only with specific network plugins). If you were previously using ethtool to disable checksum offload on your primary network interface, you should now be able to stop doing that. (#92035, @danwinship) [SIG Network and Node]
-
Kubeadm: add the deprecated flag --port=0 to kube-controller-manager and kube-scheduler manifests to disable insecure serving. Without this flag the components by default serve (e.g. /metrics) insecurely on the default node interface (controlled by --address). Users that wish to override this behavior and enable insecure serving can pass a custom --port=X via kubeadm's "extraArgs" mechanic for these components. (#92720, @neolit123) [SIG Cluster Lifecycle]
-
Kubeadm: during "join", don't re-add an etcd member if it already exists in the cluster. (#92118, @neolit123) [SIG Cluster Lifecycle]

hyperkube: Use [email protected] image
A previous release built hyperkube using the [email protected], which was updated to address a CVE in the CNI plugins.
A side-effect of using this new image was that the networking packages (namely
iptables) drifted from the versions used in the kube-proxy images.The following issues were filed on kube-proxy failures when using hyperkube:
To address this, the new debian-hyperkube-base image (v1.1.0) uses the debian-iptables base image (v12.1.0), which includes iptables-wrapper, a script used to determine the correct iptables mode to run in. (#92494, @justaugustus) [SIG Cluster Lifecycle and Release]

hyperkube: Use [email protected] image
A previous release built hyperkube using the [email protected], which was updated to address a CVE in the CNI plugins.
A side-effect of using this new image was that the networking packages (namely

To address this, the new debian-hyperkube-base image (v1.1.0) uses the debian-iptables base image (v12.1.0), which includes iptables-wrapper, a script used to determine the correct iptables mode to run in. (#92494, @justaugustus) [SIG Cluster Lifecycle and Release]

A complete changelog for the release notes is now hosted in a customizable format at relnotes.k8s.io. Check it out and please give us your feedback!
Added as a beta feature way back in v1.2, v1.17 sees the general availability of cloud provider labels.
The Kubernetes Volume Snapshot feature is now beta in Kubernetes v1.17. It was introduced as alpha in Kubernetes v1.12, with a second alpha with breaking changes in Kubernetes v1.13.
The Kubernetes in-tree storage plugin to Container Storage Interface (CSI) migration infrastructure is now beta in Kubernetes v1.17. CSI migration was introduced as alpha in Kubernetes v1.14.
- volumeDevices mapping ignored when container is privileged
- The
Should recreate evicted statefulsetconformance test fails becausePod ss-0 expected to be re-created at least once. This was caused by thePredicate PodFitsHostPorts failedscheduling error. The root cause was a host port conflict for port21017. This port was in-use as an ephemeral port by another application running on the node. This will be looked at for the 1.18 release. - client-go discovery clients constructed using
NewDiscoveryClientForConfigorNewDiscoveryClientForConfigOrDiedefault to rate limits that cause normal discovery request patterns to take several seconds. This is fixed in https://issue.k8s.io/86168 and will be resolved in v1.17.1. As a workaround, theBurstvalue can be adjusted higher in the rest.Config passed intoNewDiscoveryClientForConfigorNewDiscoveryClientForConfigOrDie. - the IP allocator in v1.17.0 can return errors such as
the cluster IP <ip> for service <service-name> is not within the service CIDR <cidr>; please recreatein the logs of the kube-apiserver. The cause is incorrect CIDR calculations if the service CIDR (--service-cluster-ip-range) is set to bits lower than/16. This is fixed in http://issue.k8s.io/86534 and will be resolved in v1.17.1.
- Kubeadm: add a new
kubelet-finalizephase as part of theinitworkflow and an experimental sub-phase to enable automatic kubelet client certificate rotation on primary control-plane nodes. Prior to 1.17 and for existing nodes created bykubeadm initwhere kubelet client certificate rotation is desired, you must modify/etc/kubernetes/kubelet.confto point to the PEM symlink for rotation:client-certificate: /var/lib/kubelet/pki/kubelet-client-current.pemandclient-key: /var/lib/kubelet/pki/kubelet-client-current.pem, replacing the embedded client certificate and key. (#84118, @neolit123)
- EndpointSlices: If upgrading a cluster with EndpointSlices already enabled, any EndpointSlices that should be managed by the EndpointSlice controller should have a
endpointslice.kubernetes.io/managed-bylabel set toendpointslice-controller.k8s.io.
- Kubeadm: when adding extra apiserver authorization-modes, the defaults
Node,RBACare no longer prepended in the resulting static Pod manifests and a full override is allowed. (#82616, @ghouscht)

x-kubernetes-list-typeandx-kubernetes-map-typeatomic to reject non-atomic sub-types. (#84722, @sttts) - Kube-apiserver: The
AdmissionConfigurationtype accepted by--admission-control-config-filehas been promoted toapiserver.config.k8s.io/v1with no schema changes. (#85098, @liggitt) - Fixed EndpointSlice port name validation to match Endpoint port name validation (allowing port names longer than 15 characters) (#84481, @robscott)
- CustomResourceDefinitions introduce
x-kubernetes-map-typeannotation as a CRD API extension. Enables this particular validation for server-side apply. (#84113, @enxebre)
- kube-apiserver: the

- Client-go: improved allocation behavior of the delaying workqueue when handling objects with far-future ready times. (#83945, @barkbay)
- Fixed an issue with informers missing an
Addedevent if a recently deleted object was immediately recreated at the same time the informer dropped a watch and relisted. (#83911, @matte21) - Fixed panic when accessing CustomResources of a CRD with
x-kubernetes-int-or-string. (#83787, @sttts) - The resource version option, when passed to a list call, is now consistently interpreted as the minimum allowed resource version. Previously when listing resources that had the watch cache disabled clients could retrieve a snapshot at that exact resource version. If the client requests a resource version newer than the current state, a TimeoutError is returned suggesting the client retry in a few seconds. This behavior is now consistent for both single item retrieval and list calls, and for when the watch cache is enabled or disabled. (#72170, @jpbetz)
- Fixes a goroutine leak in kube-apiserver when a request times out. (#83333, @lavalamp)

- Client-ca bundles for the all generic-apiserver based servers will dynamically reload from disk on content changes (#83579, @deads2k)
- Client-go: Clients can request protobuf and json and correctly negotiate with the server for JSON for CRD objects, allowing all client libraries to request protobuf if it is available. If an error occurs negotiating a watch with the server, the error is immediately return by the client
Watch()method instead of being sent as anErrorevent on the watch stream. (#84692, @smarterclayton) Renamed FeatureGate RequestManagement to APIPriorityAndFairness. This feature gate is an alpha and has not yet been associated with any actual functionality. (#85260, @MikeSpreitzer) - Filter published OpenAPI schema by making nullable, required fields non-required in order to avoid kubectl to wrongly reject null values. (#85722, @sttts)

- The mutating and validating admission webhook plugins now read configuration from the admissionregistration.k8s.io/v1 API. (#80883, @liggitt)
- kube-proxy: a configuration file specified via
--configis now loaded with strict deserialization, which fails if the config file contains duplicate or unknown fields. This protects against accidentally running with config files that are malformed, mis-indented, or have typos in field names, and getting unexpected behavior. (#82927, @obitech) - When registering with a 1.17+ API server, MutatingWebhookConfiguration and ValidatingWebhookConfiguration objects can now request that only
v1AdmissionReview requests be sent to them. Previously, webhooks were required to support receivingv1beta1AdmissionReview requests as well for compatibility with API servers <= 1.15.- When registering with a 1.17+ API server, a CustomResourceDefinition conversion webhook can now request that only
v1ConversionReview requests be sent to them. Previously, conversion webhooks were required to support receivingv1beta1ConversionReview requests as well for compatibility with API servers <= 1.15. (#82707, @liggitt)
- When registering with a 1.17+ API server, a CustomResourceDefinition conversion webhook can now request that only
- OpenAPI v3 format in CustomResourceDefinition schemas are now documented. (#85381, @sttts)

- Add table convertor to component status. (#85174, @zhouya0)
- Scale custom resource unconditionally if resourceVersion is not provided (#80572, @knight42)
- When the go-client reflector relists, the ResourceVersion list option is set to the reflector's latest synced resource version to ensure the reflector does not "go back in time" and reprocess events older than it has already processed. If the server responds with an HTTP 410 (Gone) status code response, the relist falls back to using
resourceVersion="". (#83520, @jpbetz) - Fix unsafe JSON construction in a number of locations in the codebase (#81158, @zouyee)
- Fixes a flaw (CVE-2019-11253) in json/yaml decoding where large or malformed documents could consume excessive server resources. Request bodies for normal API requests (create/delete/update/patch operations of regular resources) are now limited to 3MB. (#83261, @liggitt)
- CRDs can have fields named
typewith valuearrayand nested array withitemsfields without validation to fall over this. (#85223, @sttts)
- Support Service Topology (#72046, @m1093782566)
- Finalizer Protection for Service LoadBalancers is now in GA (enabled by default). This feature ensures the Service resource is not fully deleted until the correlating load balancer resources are deleted. (#85023, @MrHohn)

- Fixed the bug that deleted services were processed by EndpointSliceController repeatedly even their cleanup were successful. (#82996, @tnqn)
- An end-user may choose to request logs without confirming the identity of the backing kubelet. This feature can be disabled by setting the
AllowInsecureBackendProxyfeature-gate to false. (#83419, @deads2k) - When scaling down a ReplicaSet, delete doubled up replicas first, where a "doubled up replica" is defined as one that is on the same node as an active replica belonging to a related ReplicaSet. ReplicaSets are considered "related" if they have a common controller (typically a Deployment). (#80004, @Miciah)

- Privilege escalation has been disabled for all containers. (#82347, @pjbgf)
-
Kubernetes no longer monitors firewalld. On systems using firewalld for firewall maintenance, kube-proxy will take slightly longer to recover from disruptive firewalld operations that delete kube-proxy's iptables rules.
As a side effect of these changes, kube-proxy's
sync_proxy_rules_last_timestamp_secondsmetric no longer behaves the way it used to; now it will only change when services or endpoints actually change, rather than reliably updating every 60 seconds (or whatever). If you are trying to monitor for whether iptables updates are failing, thesync_proxy_rules_iptables_restore_failures_totalmetric may be more useful. (#81517, @danwinship)

- kubeadm: fix a panic in case the KubeProxyConfiguration feature gates were not initialized. (#85524, @Arvinderpal)
- kubeadm: fix stray "node-cidr-mask-size" flag in the kube-controller-manager manifest when IPv6DualStack is enabled (#85494, @tedyu)
- CRDs can have fields named
typewith valuearrayand nested array withitemsfields without validation to fall over this. (#85223, @sttts) - Resolves error from v1.17.0-beta.2 with --authorizer-mode webhook complaining about an invalid version (#85441, @liggitt)
- Promote CSIMigrationAWS to Beta (off by default since it requires installation of the AWS EBS CSI Driver) (#85237, @leakingtapan)
- The in-tree AWS EBS plugin "kubernetes.io/aws-ebs" is now deprecated and will be removed in 1.21. Users should enable CSIMigration + CSIMigrationAWS features and install the AWS EBS CSI Driver (https://github.com/kubernetes-sigs/aws-ebs-csi-driver) to avoid disruption to existing Pod and PVC objects at that time.
- Users should start using the AWS EBS CSI CSI Driver directly for any new volumes.

- Renamed FeatureGate RequestManagement to APIPriorityAndFairness. This feature gate is an alpha and has not yet been associated with any actual functionality. (#85260, @MikeSpreitzer)
- Action required: change references to feature gate RequestManagement into references to APIPriorityAndFairness
- ACTION REQUIRED: kubeadm: add a new "kubelet-finalize" phase as part of the "init" workflow and an experimental sub-phase to enable automatic kubelet client certificate rotation on primary control-plane nodes. (#84118, @neolit123)
- Prior to 1.17 and for existing nodes created by "kubeadm init" where kubelet client certificate rotation is desired, you must modify "/etc/kubernetes/kubelet.conf" to point to the PEM symlink for rotation:
- "client-certificate: /var/lib/kubelet/pki/kubelet-client-current.pem" and "client-key: /var/lib/kubelet/pki/kubelet-client-current.pem", replacing the embedded client certificate and key.
- action required: kubeadm deprecates the use of the hyperkube image (#85094, @rosti)

- Feature gates CSIMigration to Beta (on by default) and CSIMigrationGCE to Beta (off by default since it requires installation of the GCE PD CSI Driver) (#85231, @davidz627)
- The in-tree GCE PD plugin "kubernetes.io/gce-pd" is now deprecated and will be removed in 1.21. Users should enable CSIMigration + CSIMigrationGCE features and install the GCE PD CSI Driver (https://github.com/kubernetes-sigs/gcp-compute-persistent-disk-csi-driver) to avoid disruption to existing Pod and PVC objects at that time.
- Users should start using the GCE PD CSI CSI Driver directly for any new volumes.
- kube-controller-manager: Fixes bug setting headless service labels on endpoints (#85361, @liggitt)

- Reduce default NodeStatusReportFrequency to 5 minutes. With this change, periodic node status updates will be send every 5m if node status doesn't change (otherwise they are still send with 10s). (#84007, @wojtek-t)
- Bump NodeProblemDetector version to v0.8.0 to reduce forced NodeStatus updates frequency to 5 minutes.
- CSI Topology feature is GA. The CSINodeInfo feature gate is deprecated and will be removed in a future release. The storage.k8s.io/v1beta1 CSINode object is deprecated and will be removed in a future release. (#83474, @msau42)
- Only validate duplication of the RequestedToCapacityRatio custom priority and allow other custom predicates/priorities (#84646, @liu-cong)
- Added kubelet serving certificate metric
server_rotation_secondswhich is a histogram reporting the age of a just rotated serving certificate in seconds. (#84534, @sambdavidson) - During namespace deletion some controllers create event and log spam because they do not recognize namespace deletion as a terminal state. (#84123, @smarterclayton)
- Removed Alpha feature
MountContainers(#84365, @codenrhoden) - People can see the right log and note. (#84637, @zhipengzuo)

- deprecate cleanup-ipvs flag (#83832, @gongguan)
- Scheduler Policy API has a new recommended apiVersion "apiVersion: kubescheduler.config.k8s.io/v1" which is consistent with the scheduler API group "kubescheduler.config.k8s.io". It holds the same API as the old apiVersion "apiVersion: v1". (#83578, @Huang-Wei)
- Fixed a bug in the single-numa-policy of the TopologyManager. Previously, best-effort pods would result in a terminated state with a TopologyAffinity error. Now they will run as expected. (#83777, @lmdaly)
- local: support local filesystem volume with block resource reconstruction (#84218, @cofyc)
- Fix the bug that EndpointSlice for masters wasn't created after enabling EndpointSlice feature on a pre-existing cluster. (#84421, @tnqn)
- kubelet: a configuration file specified via
--configis now loaded with strict deserialization, which fails if the config file contains duplicate or unknown fields. This protects against accidentally running with config files that are malformed, mis-indented, or have typos in field names, and getting unexpected behavior. (#83204, @obitech) - kubeadm now propagates proxy environment variables to kube-proxy (#84559, @yastij)
- Reload apiserver SNI certificates from disk every minute (#84303, @jackkleeman)
- sourcesReady provides the readiness of kubelet configuration sources such as apiserver update readiness. (#81344, @zouyee)

- Update default etcd server version to 3.4.3 (#84329, @jingyih)
- Scheduler policy configs can no longer be declared multiple times (#83963, @damemi)
- This PR sets the --cluster-dns flag value to kube-dns service IP whether or not NodeLocal DNSCache is enabled. NodeLocal DNSCache will listen on both the link-local as well as the service IP. (#84383, @prameshj)
- Remove prometheus cluster monitoring addon from kube-up (#83442, @serathius)
- update the latest validated version of Docker to 19.03 (#84476, @neolit123)
- kubeadm: always mount the kube-controller-manager hostPath volume that is given by the --flex-volume-plugin-dir flag. (#84468, @neolit123)
- Introduce x-kubernetes-map-type annotation as a CRD API extension. Enables this particular validation for server-side apply. (#84113, @enxebre)
- kube-scheduler now fallbacks to emitting events using core/v1 Events when events.k8s.io/v1beta1 is disabled. (#83692, @yastij)
- Migrate controller-manager and scheduler to EndpointsLeases leader election. (#84084, @wojtek-t)

- CSI detach timeout increased from 10 seconds to 2 minutes (#84321, @cduchesne)
- Update etcd client side to v3.4.3 (#83987, @wenjiaswe)
- Deprecated prometheus request meta-metrics have been removed (http_request_duration_microseconds, http_request_duration_microseconds_sum, http_request_duration_microseconds_count, http_request_size_bytes, http_request_size_bytes_sum, http_request_size_bytes_count, http_requests_total, http_response_size_bytes, http_response_size_bytes_sum, http_response_size_bytes_count) due to removal from the prometheus client library. Prometheus http request meta-metrics are now generated from promhttp.InstrumentMetricHandler instead.
- The built-in system:csi-external-provisioner and system:csi-external-attacher cluster roles are removed as of 1.17 release (#84282, @tedyu)

- Adds a metric apiserver_request_error_total to kube-apiserver. This metric tallies the number of request_errors encountered by verb, group, version, resource, subresource, scope, component, and code. (#83427, @logicalhan)
- Refactor scheduler's framework permit API. (#83756, @hex108)
- The kubectl's api-resource command now has a
--sort-byflag to sort resources by name or kind. (#81971, @laddng) - Update to use go1.12.12 (#84064, @cblecker)

- When scaling down a ReplicaSet, delete doubled up replicas first, where a "doubled up replica" is defined as one that is on the same node as an active replica belonging to a related ReplicaSet. ReplicaSets are considered "related" if they have a common controller (typically a Deployment). (#80004, @Miciah)
- Promote WatchBookmark feature to GA. (#83195, @wojtek-t)
- With WatchBookmark feature, clients are able to request watch events with BOOKMARK type. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session.

- Expand scheduler priority functions and scheduling framework plugins' node score range to [0, 100]. action required. Note: this change is internal and does not affect extender and RequestedToCapacityRatio custom priority, which are still expected to provide a [0, 10] range. (#83522, @draveness)
- action required: kubeadm: when adding extra apiserver authorization-modes, the defaults "Node,RBAC" are no longer prepended in the resulting static Pod manifests and a full override is allowed. (#82616, @ghouscht)
- ACTION REQUIRED: kubeadm: properly enable kubelet client certificate rotation on primary control-plane nodes, created using "kubeadm init". A side effect of this change is that for external CA users, kubeadm now requires "bootstrap-kubelet.conf" instead of "kubelet.conf" during "kubeadm init" and its phases. (#83339, @neolit123)
- Action Required:
kubeadm.k8s.io/v1beta1has been deprecated, you should update your config to use newer non-deprecated API versions. (#83276, @Klaven)
- [migration phase 1] PodFitsHostPorts as filter plugin (#83659, @wgliang)
- [migration phase 1] PodFitsResources as framework plugin (#83650, @wgliang)
- Fixed attachment of AWS volumes that have just been detached. (#83567, @jsafrane)
- [migration phase 1] PodMatchNodeSelector/NodAffinity as filter plugin (#83660, @wgliang)
- Upgrade to etcd client 3.3.17 to fix bug where etcd client does not parse IPv6 addresses correctly when members are joining, and to fix bug where failover on multi-member etcd cluster fails certificate check on DNS mismatch (#83801, @jpbetz)
- Fixed panic when accessing CustomResources of a CRD with x-kubernetes-int-or-string. (#83787, @sttts)
- Change
pod_preemption_victimsmetric from Gauge to Histogram. (#83603, @Tabrizian) - Expose SharedInformerFactory in the framework handle (#83663, @draveness)

- [migration phase 1] PodFitsHost as filter plugin (#83662, @wgliang)
- The topology manager aligns resources for pods of all QoS classes with respect to NUMA locality, not just Guaranteed QoS pods. (#83492, @ConnorDoyle)
- Fix unsafe JSON construction in a number of locations in the codebase (#81158, @zouyee)
- Fixed a bug in the single-numa-node policy of the TopologyManager. Previously, pods that only requested CPU resources and did not request any third-party devices would fail to launch with a TopologyAffinity error. Now they will launch successfully. (#83697, @klueska)
- Add per-pod scheduling metrics across 1 or more schedule attempts. (#83674, @liu-cong)
- Fix validation message to mention bytes, not characters. (#80880, @DirectXMan12)
- external facing APIs in pluginregistration and deviceplugin packages are now available under k8s.io/kubelet/pkg/apis/ (#83551, @dims)
- Fix error where metrics related to dynamic kubelet config isn't registered (#83184, @odinuge)
- The VolumeSubpathEnvExpansion feature is graduating to GA. The
VolumeSubpathEnvExpansionfeature gate is unconditionally enabled, and will be removed in v1.19. (#82578, @kevtaylor) - Openstack: Do not delete managed LB in case of security group reconciliation errors (#82264, @multi-io)
- The mutating and validating admission webhook plugins now read configuration from the admissionregistration.k8s.io/v1 API. (#80883, @liggitt)
- kubeadm: implemented structured output of 'kubeadm token list' in JSON, YAML, Go template and JsonPath formats (#78764, @bart0sh)
- kube-proxy: a configuration file specified via
--configis now loaded with strict deserialization, which fails if the config file contains duplicate or unknown fields. This protects against accidentally running with config files that are malformed, mis-indented, or have typos in field names, and getting unexpected behavior. (#82927, @obitech) - Add "podInitialBackoffDurationSeconds" and "podMaxBackoffDurationSeconds" to the scheduler config API (#81263, @draveness)
- Authentication token cache size is increased (from 4k to 32k) to support clusters with many nodes or many namespaces with active service accounts. (#83643, @lavalamp)
- Bumps the minimum version of Go required for building Kubernetes to 1.12.4. (#83596, @jktomer)
- kube-proxy iptables probabilities are now more granular and will result in better distribution beyond 319 endpoints. (#83599, @robscott)
- Fixed the bug that deleted services were processed by EndpointSliceController repeatedly even their cleanup were successful. (#82996, @tnqn)
- If a bad flag is supplied to a kubectl command, only a tip to run --help is printed, instead of the usage menu. Usage menu is printed upon running
kubectl command --help. (#82423, @sallyom) - If container fails because ContainerCannotRun, do not utilize the FallbackToLogsOnError TerminationMessagePolicy, as it masks more useful logs. (#81280, @yqwang-ms)
- Fixed cleanup of raw block devices after kubelet restart. (#83451, @jsafrane)
- Commands like
kubectl applynow return errors if schema-invalid annotations are specified, rather than silently dropping the entire annotations section. (#83552, @liggitt) - Expose kubernetes client in the scheduling framework handle. (#82432, @draveness)
- kubeadm: fix wrong default value for the "upgrade node --certificate-renewal" flag. (#83528, @neolit123)
- IP validates if a string is a valid IP address (#83104, @zouyee)
- The
--certificate-authorityflag now correctly overrides existing skip TLS or CA data settings in the kubeconfig file (#83547, @liggitt) - hyperkube will now be available in a new github repository and will not be included in the kubernetes release from 1.17 onwards (#83454, @dims)
- more complete and accurate logging of stack backtraces in E2E failures (#82176, @pohly)
- Kubeadm: add support for 127.0.0.1 as advertise address. kubeadm will automatically replace this value with matching global unicast IP address on the loopback interface. (#83475, @fabriziopandini)
- Rename PluginContext to CycleState in the scheduling framework (#83430, @draveness)
- kube-scheduler: a configuration file specified via
--configis now loaded with strict deserialization, which fails if the config file contains duplicate or unknown fields. This protects against accidentally running with config files that are malformed, mis-indented, or have typos in field names, and getting unexpected behavior. (#83030, @obitech) - Significant kube-proxy performance improvements for non UDP ports. (#83208, @robscott)
- Fixes a flaw (CVE-2019-11253) in json/yaml decoding where large or malformed documents could consume excessive server resources. Request bodies for normal API requests (create/delete/update/patch operations of regular resources) are now limited to 3MB. (#83261, @liggitt)

- New APIs to allow adding/removing pods from pre-calculated prefilter state in the scheduling framework (#82912, @ahg-g)
- Conformance tests may now include disruptive tests. If you are running tests against a live cluster, consider skipping those tests tagged as
Disruptiveto avoid non-test workloads being impacted. Be aware, skipping any conformance tests (even disruptive ones) will make the results ineligible for consideration for the CNCF Certified Kubernetes program. (#82664, @johnSchnake) - Resolves regression generating informers for packages whose names contain
.characters (#82410, @nikhita) - Added metrics 'authentication_latency_seconds' that can be used to understand the latency of authentication. (#82409, @RainbowMango)

- Fix possible fd leak and closing of dirs when using openstack (#82873, @odinuge)
- PersistentVolumeLabel admission plugin, responsible for labeling
PersistentVolumeswith topology labels, now does not overwrite existing labels on PVs that were dynamically provisioned. It trusts the dynamic provisioning that it provided the correct labels to thePersistentVolume, saving one potentially expensive cloud API call.PersistentVolumescreated manually by users are labelled by the admission plugin in the same way as before.
