API Change
- Fixes a 1.30.0 regression in openapi descriptions of imagePullSecrets and hostAliases fields to mark the fields used as keys in those lists as either defaulted or required. ([kubernetes/kubernetes124553](https://github.com/kubernetes/kubernetes/pull/124553), [pmalek](https://github.com/pmalek)) [SIG API Machinery]
- Fixes a 1.30.0 regression in openapi descriptions of imagePullSecrets and hostAliases fields to mark the fields used as keys in those lists as either defaulted or required. ([kubernetes/kubernetes124694](https://github.com/kubernetes/kubernetes/pull/124694), [pmalek](https://github.com/pmalek)) [SIG API Machinery]
- Added (alpha) support for the `managedBy` field on Jobs. Jobs with a custom value of this field - any value other than `kubernetes.io/job-controller` - were skipped by the job controller, and their reconciliation was delegated to an external controller, indicated by the value of the field. Jobs that didn't have this field at all, or where the field value was the reserved string `kubernetes.io/job-controller`, were reconciled by the built-in job controller.
([kubernetes/kubernetes123273](https://github.com/kubernetes/kubernetes/pull/123273), [mimowo](https://github.com/mimowo))
- Added alpha-level support for the SuccessPolicy in Jobs.
([kubernetes/kubernetes123412](https://github.com/kubernetes/kubernetes/pull/123412), [tenzen-y](https://github.com/tenzen-y))
- Added the `CEL` library for IP Addresses and CIDRs. This was made available for use starting from version `1.31`.
([kubernetes/kubernetes121912](https://github.com/kubernetes/kubernetes/pull/121912), [JoelSpeed](https://github.com/JoelSpeed))
- Allowed container runtimes to fix an image garbage collection bug by adding an `image_id` field to the CRI Container message.
([kubernetes/kubernetes123508](https://github.com/kubernetes/kubernetes/pull/123508), [saschagrunert](https://github.com/saschagrunert))
- Dynamic Resource Allocation: DRA drivers can now use "structured parameters" to let the scheduler handle claim allocation.
([kubernetes/kubernetes123516](https://github.com/kubernetes/kubernetes/pull/123516), [pohly](https://github.com/pohly))
- Fixed accidental enablement of the new alpha `optionalOldSelf` API field in `CustomResourceDefinition` validation rules, which should only have been allowed to be set when the `CRDValidationRatcheting` feature gate is enabled.
([kubernetes/kubernetes122329](https://github.com/kubernetes/kubernetes/pull/122329), [jpbetz](https://github.com/jpbetz))
- Implemented the `prescore` extension point for the `volumeBinding` plugin. It now returns skip if it doesn't do anything in Score.
([kubernetes/kubernetes115768](https://github.com/kubernetes/kubernetes/pull/115768), [AxeZhan](https://github.com/AxeZhan))
- Kubelet would fail if NodeSwap was used with LimitedSwap and cgroupv1 node.
([kubernetes/kubernetes123738](https://github.com/kubernetes/kubernetes/pull/123738), [kannon92](https://github.com/kannon92))
- Promoted `AdmissionWebhookMatchConditions` to GA. The feature is now stable, and the feature gate is now locked to default.
([kubernetes/kubernetes123560](https://github.com/kubernetes/kubernetes/pull/123560), [ivelichkovich](https://github.com/ivelichkovich))
- Structured Authentication Configuration now supports `DiscoveryURL`. If specified, `discoveryURL` overrides the URL used to fetch discovery information. This is for scenarios where the well-known and jwks endpoints are hosted at a different location than the issuer (such as locally in the cluster).
([kubernetes/kubernetes123527](https://github.com/kubernetes/kubernetes/pull/123527), [aramase](https://github.com/aramase))
- The `StorageVersionMigration` API, previously available as a Custom Resource Definition (CRD), is now a built-in API in Kubernetes.
([kubernetes/kubernetes123344](https://github.com/kubernetes/kubernetes/pull/123344), [nilekhc](https://github.com/nilekhc))
- When configuring a JWT authenticator:
If `username.expression` used 'claims.email', then 'claims.email_verified' must have been used in `username.expression` or `extra[*].valueExpression` or `claimValidationRules[*].expression`. An example claim validation rule expression that matches the validation automatically applied when `username.claim` is set to 'email' is 'claims.?email_verified.orValue(true)'.
([kubernetes/kubernetes123737](https://github.com/kubernetes/kubernetes/pull/123737), [enj](https://github.com/enj))
- `readOnly` volumes now support recursive read-only mounts for kernel versions >= 5.12."
([kubernetes/kubernetes123180](https://github.com/kubernetes/kubernetes/pull/123180), [AkihiroSuda](https://github.com/AkihiroSuda))
- cri-api: Implemented KEP-3857: Recursive Read-only (RRO) mounts.
([kubernetes/kubernetes123272](https://github.com/kubernetes/kubernetes/pull/123272), [AkihiroSuda](https://github.com/AkihiroSuda))
- kube-apiserver: the AuthenticationConfiguration type accepted in `--authentication-config` files has been promoted to `apiserver.config.k8s.io/v1beta1`.
([kubernetes/kubernetes123696](https://github.com/kubernetes/kubernetes/pull/123696), [aramase](https://github.com/aramase))
- kubelet allowed specifying a custom root directory for pod logs (instead of the default /var/log/pods) using the `podLogsDir` key in kubelet configuration.
([kubernetes/kubernetes112957](https://github.com/kubernetes/kubernetes/pull/112957), [mxpv](https://github.com/mxpv))
- resource.k8s.io/ResourceClaim (alpha API): The strategic merge patch strategy for the `status.reservedFor` array was changed so that a strategic-merge-patch can now add individual entries. This change may break clients using strategic merge patch to update status, which rely on the previous behavior (replacing the entire array).
([kubernetes/kubernetes122276](https://github.com/kubernetes/kubernetes/pull/122276), [pohly](https://github.com/pohly))
- Added a CBOR implementation of `runtime.Serializer`. Until CBOR graduates to Alpha, API servers will refuse to start if configured with CBOR support. ([kubernetes/kubernetes122881](https://github.com/kubernetes/kubernetes/pull/122881), [benluddy](https://github.com/benluddy))
- Added a alpha feature, behind the `RelaxedEnvironmentVariableValidation` feature gate.
When that gate is enabled, Kubernetes allows almost all printable ASCII characters to be used in the names
of environment variables for containers in Pods. ([kubernetes/kubernetes123385](https://github.com/kubernetes/kubernetes/pull/123385), [HirazawaUi](https://github.com/HirazawaUi))
- Added a new (alpha) field, `trafficDistribution`, to the Service `spec` to express preferences for traffic distribution to endpoints. Enabled through the `ServiceTrafficDistribution` feature gate. ([kubernetes/kubernetes123487](https://github.com/kubernetes/kubernetes/pull/123487), [gauravkghildiyal](https://github.com/gauravkghildiyal))
- Added audienceMatchPolicy field to AuthenticationConfiguration and support for configuring multiple audiences.
The "audienceMatchPolicy" can be empty (or unset) when a single audience is specified in the "audiences" field.
The "audienceMatchPolicy" must be set to "MatchAny" when multiple audiences are specified in the "audiences" field. ([kubernetes/kubernetes123165](https://github.com/kubernetes/kubernetes/pull/123165), [aramase](https://github.com/aramase))
- Added consistent vanity import to files and provided tooling for verifying and updating them. ([kubernetes/kubernetes120642](https://github.com/kubernetes/kubernetes/pull/120642), [jcchavezs](https://github.com/jcchavezs))
- Added the `disable-force-detach` CLI option for `kube-controller-manager`. By default, it's set to `false`. When enabled, it prevents force detaching volumes based on maximum unmount time and node status. If activated, the non-graceful node shutdown feature must be used to recover from node failure. Additionally, if a pod needs to be forcibly terminated at the risk of corruption, the appropriate VolumeAttachment object must be deleted. ([kubernetes/kubernetes120344](https://github.com/kubernetes/kubernetes/pull/120344), [rohitssingh](https://github.com/rohitssingh))
- Added to `MutableFeatureGate` the ability to override the default setting of feature gates, to allow default-enabling a feature on a component-by-component basis instead of for all affected components simultaneously. ([kubernetes/kubernetes122647](https://github.com/kubernetes/kubernetes/pull/122647), [benluddy](https://github.com/benluddy))
- Aggregated discovery supports both `v2beta1` and v2 types and feature is promoted to GA. ([kubernetes/kubernetes122882](https://github.com/kubernetes/kubernetes/pull/122882), [Jefftree](https://github.com/Jefftree))
- Alpha support for field selectors on custom resources has been added. With the `CustomResourceFieldSelectors` feature gate enabled, the CustomResourceDefinition API now allows specifying `selectableFields`. Listing a field there enables filtering custom resources for that CustomResourceDefinition in list or watch requests. ([kubernetes/kubernetes122717](https://github.com/kubernetes/kubernetes/pull/122717), [jpbetz](https://github.com/jpbetz))
- AppArmor profiles can now be configured through fields on the `PodSecurityContext` and container `SecurityContext`. The beta AppArmor annotations are deprecated, and AppArmor status is no longer included in the node ready condition. ([kubernetes/kubernetes123435](https://github.com/kubernetes/kubernetes/pull/123435), [tallclair](https://github.com/tallclair))
- Contextual logging is now in beta and enabled by default. Check out the [KEP](https://github.com/kubernetes/enhancements/issues/3077) and [official documentation](https://kubernetes.io/docs/concepts/cluster-administration/system-logs/#contextual-logging) for more details. ([kubernetes/kubernetes122589](https://github.com/kubernetes/kubernetes/pull/122589), [pohly](https://github.com/pohly))

([kubernetes/kubernetes114301](https://github.com/kubernetes/kubernetes/pull/114301), [harshanarayana](https://github.com/harshanarayana))
- Graduated pod scheduling gates to general availability.
The `PodSchedulingReadiness` feature gate no longer has any effect, and the
`.spec.schedulingGates` field is always available within the Pod and PodTemplate APIs. ([kubernetes/kubernetes123575](https://github.com/kubernetes/kubernetes/pull/123575), [Huang-Wei](https://github.com/Huang-Wei))
- Graduated support for `minDomains` in pod topology spread constraints, to general availability.
The `MinDomainsInPodTopologySpread` feature gate no longer has any effect, and the field is
always available within the Pod and PodTemplate APIs. ([kubernetes/kubernetes123481](https://github.com/kubernetes/kubernetes/pull/123481), [sanposhiho](https://github.com/sanposhiho))
- In kubelet configuration, the `.memorySwap.swapBehavior` field now accepts a new value `NoSwap`, which becomes the default if unspecified. The previously accepted `UnlimitedSwap` value has been dropped.
([kubernetes/kubernetes122745](https://github.com/kubernetes/kubernetes/pull/122745), [kannon92](https://github.com/kannon92))
- Kube-apiserver: the AuthorizationConfiguration type accepted in `--authorization-config` files has been promoted to `apiserver.config.k8s.io/v1beta1`. ([kubernetes/kubernetes123640](https://github.com/kubernetes/kubernetes/pull/123640), [liggitt](https://github.com/liggitt))
- OIDC authentication will now fail if the username asserted based on a CEL expression config is the empty string. Previously the request would be authenticated with the username set to the empty string. ([kubernetes/kubernetes123568](https://github.com/kubernetes/kubernetes/pull/123568), [enj](https://github.com/enj))
- Removed note that `hostAliases` are not supported on hostNetwork Pods from the PodSpec API. The feature has been supported since v1.8. ([kubernetes/kubernetes122422](https://github.com/kubernetes/kubernetes/pull/122422), [neolit123](https://github.com/neolit123))
- Structured Authentication Configuration now supports configuring multiple JWT authenticators. The maximum allowed JWT authenticators in the authentication configuration is 64. ([kubernetes/kubernetes123431](https://github.com/kubernetes/kubernetes/pull/123431), [aramase](https://github.com/aramase))
- Text logging in Kubernetes components now uses [textlogger](https://pkg.go.dev/k8s.io/klog/v2v2.120.0/textlogger). The same split streams of info and error log entries with buffering of info entries is now also supported for text output (off by default, alpha feature). Previously, this was only supported for JSON. Performance is better also without split streams. ([kubernetes/kubernetes#114672](https://github.com/kubernetes/kubernetes/pull/114672), [pohly](https://github.com/pohly))
- The API server now detects and fails on startup if there are conflicting issuers between JWT authenticators and service account configurations. Previously, such configurations would run but could be inconsistently effective depending on the credential. ([kubernetes/kubernetes123561](https://github.com/kubernetes/kubernetes/pull/123561), [enj](https://github.com/enj))
- The JWT authenticator configuration set via the `--authentication-config` flag is now dynamically reloaded as the file changes on disk. ([kubernetes/kubernetes123525](https://github.com/kubernetes/kubernetes/pull/123525), [enj](https://github.com/enj))
- The `StructuredAuthenticationConfiguration` feature is now beta and enabled. ([kubernetes/kubernetes123719](https://github.com/kubernetes/kubernetes/pull/123719), [enj](https://github.com/enj))

([kubernetes/kubernetes122729](https://github.com/kubernetes/kubernetes/pull/122729), [jparrill](https://github.com/jparrill))
- The kubernetes repo now uses Go workspaces. This should not impact end users at all, but does have impact for developers of downstream projects. Switching to workspaces caused some breaking changes in the flags to the various k8s.io/code-generator tools. Downstream consumers should look at staging/src/k8s.io/code-generator/kube_codegen.sh to see the changes. ([kubernetes/kubernetes123529](https://github.com/kubernetes/kubernetes/pull/123529), [thockin](https://github.com/thockin))
- Updated an audit annotation key used by the `…/serviceaccounts/<name>/token` resource handler.
The annotation used to persist the issued credential identifier is now `authentication.kubernetes.io/issued-credential-id`. ([kubernetes/kubernetes123098](https://github.com/kubernetes/kubernetes/pull/123098), [munnerz](https://github.com/munnerz)) [SIG Auth]
- Users are now allowed to mutate `FSGroupPolicy` and `PodInfoOnMount` in `CSIDriver.Spec`. ([kubernetes/kubernetes116209](https://github.com/kubernetes/kubernetes/pull/116209), [haoruan](https://github.com/haoruan))

- When scheduling a mix of pods using `ResourceClaims` and others that don't, scheduling a pod with `ResourceClaims` has a lower impact on scheduling latency. ([kubernetes/kubernetes121876](https://github.com/kubernetes/kubernetes/pull/121876), [pohly](https://github.com/pohly))
- When working with client-go events, it's now recommended to use `NewEventBroadcasterAdapterWithContext` instead of `NewEventBroadcasterAdapter` if contextual logging support is needed. ([kubernetes/kubernetes122142](https://github.com/kubernetes/kubernetes/pull/122142), [pohly](https://github.com/pohly))
- A new (alpha) field, `trafficDistribution`, has been added to the Service `spec`.
This field provides a way to express preferences for how traffic is distributed to the endpoints for a Service.
It can be enabled through the `ServiceTrafficDistribution` feature gate. ([kubernetes/kubernetes123487](https://github.com/kubernetes/kubernetes/pull/123487), [gauravkghildiyal](https://github.com/gauravkghildiyal)) [SIG API Machinery, Apps and Network]

don't have this field at all, or where the field value is the reserved string `kubernetes.io/job-controller`,
are reconciled by the built-in job controller. ([kubernetes/kubernetes123273](https://github.com/kubernetes/kubernetes/pull/123273), [mimowo](https://github.com/mimowo)) [SIG API Machinery, Apps and Testing]
- Added a alpha feature, behind the `RelaxedEnvironmentVariableValidation` feature gate.

- Added alpha support for field selectors on custom resources.
Provided that the `CustomResourceFieldSelectors` feature gate is enabled, the CustomResourceDefinition
API now lets you specify `selectableFields`. Listing a field there allows filtering custom resources for that
CustomResourceDefinition in **list** or **watch** requests. ([kubernetes/kubernetes122717](https://github.com/kubernetes/kubernetes/pull/122717), [jpbetz](https://github.com/jpbetz)) [SIG API Machinery]

- Text logging in Kubernetes components now uses [textlogger](https://pkg.go.dev/k8s.io/klog/v2v2.120.0/textlogger). The same split streams of info and error log entries with buffering of info entries is now also supported for text output (off by default, alpha feature). Previously, this was only supported for JSON. Performance is better also without split streams.

- This change adds the following CLI option for `kube-controller-manager`:
- `disable-force-detach` (defaults to `false`): Prevent force detaching volumes based on maximum unmount time and node status. If enabled, the non-graceful node shutdown feature must be used to recover from node failure (see https://kubernetes.io/blog/2023/08/16/kubernetes-1-28-non-graceful-node-shutdown-ga/). If enabled and a pod must be forcibly terminated at the risk of corruption, then the appropriate VolumeAttachment object (see here: https://kubernetes.io/docs/reference/kubernetes-api/config-and-storage-resources/volume-attachment-v1/) must be deleted.

- Updated an audit annotation key used by the `…/serviceaccounts/<name>/token` resource handler.
The annotation used to persist the issued credential identifier is now `authentication.kubernetes.io/issued-credential-id`. ([kubernetes/kubernetes123098](https://github.com/kubernetes/kubernetes/pull/123098), [munnerz](https://github.com/munnerz)) [SIG Auth]
- Add CEL library for IP Addresses and CIDRs. This will not be available for use until 1.31. ([kubernetes/kubernetes121912](https://github.com/kubernetes/kubernetes/pull/121912), [JoelSpeed](https://github.com/JoelSpeed)) [SIG API Machinery]
- Added to MutableFeatureGate the ability to override the default setting of feature gates, to allow default-enabling a feature on a component-by-component basis instead of for all affected components simultaneously. ([kubernetes/kubernetes122647](https://github.com/kubernetes/kubernetes/pull/122647), [benluddy](https://github.com/benluddy)) [SIG API Machinery and Cluster Lifecycle]
- Adds a rule on the kube_codegen tool to ignore vendor folder during the code generation. ([kubernetes/kubernetes122729](https://github.com/kubernetes/kubernetes/pull/122729), [jparrill](https://github.com/jparrill)) [SIG API Machinery and Cluster Lifecycle]
- Allow users to mutate FSGroupPolicy and PodInfoOnMount in CSIDriver.Spec ([kubernetes/kubernetes116209](https://github.com/kubernetes/kubernetes/pull/116209), [haoruan](https://github.com/haoruan)) [SIG API Machinery, Storage and Testing]
- Client-go events: `NewEventBroadcasterAdapterWithContext` should be used instead of `NewEventBroadcasterAdapter` if the goal is to support contextual logging. ([kubernetes/kubernetes122142](https://github.com/kubernetes/kubernetes/pull/122142), [pohly](https://github.com/pohly)) [SIG API Machinery, Instrumentation and Scheduling]
- Fixes accidental enablement of the new alpha `optionalOldSelf` API field in CustomResourceDefinition validation rules, which should only be allowed to be set when the CRDValidationRatcheting feature gate is enabled. ([kubernetes/kubernetes122329](https://github.com/kubernetes/kubernetes/pull/122329), [jpbetz](https://github.com/jpbetz)) [SIG API Machinery]
- Implement `prescore` extension point for `volumeBinding` plugin. Return skip if it doesn't do anything in Score. ([kubernetes/kubernetes115768](https://github.com/kubernetes/kubernetes/pull/115768), [AxeZhan](https://github.com/AxeZhan)) [SIG Scheduling, Storage and Testing]
- Resource.k8s.io/ResourceClaim (alpha API): the strategic merge patch strategy for the `status.reservedFor` array was changed such that a strategic-merge-patch can add individual entries. This breaks clients using strategic merge patch to update status which rely on the previous behavior (replacing the entire array). ([kubernetes/kubernetes122276](https://github.com/kubernetes/kubernetes/pull/122276), [pohly](https://github.com/pohly)) [SIG API Machinery]
- When scheduling a mixture of pods using ResourceClaims and others which don't, scheduling a pod with ResourceClaims impacts scheduling latency less.
