# v12.0.1

Kubernetes API Version: 1.16.15

**Breaking Change:**

- `kubernetes.config.Configuration()` will now return the default "initial" configuration, `kubernetes.config.Configuration.get_default_copy()` will return the default configuration if there is a default set via `Configuration.set_default(c)`, otherwise, it will also return the default "initial" configuration. [OpenAPITools/openapi-generator#4485](https://github.com/OpenAPITools/openapi-generator/pull/4485), [OpenAPITools/openapi-generator#5315](https://github.com/OpenAPITools/openapi-generator/pull/5315). **Note: ** This change also affects v12.0.0a1, v12.0.0b1 and v12.0.0.

# v12.0.0a1

Kubernetes API Version: 1.16.14

**API Change:**

- Resolve regression in metadata.managedFields handling in update/patch requests submitted by older API clients ([#91748](https://github.com/kubernetes/kubernetes/pull/91748), [@apelisse](https://github.com/apelisse)) [SIG API Machinery and Testing]
- Fix bug where sending a status update completely wipes managedFields for some types. ([#90033](https://github.com/kubernetes/kubernetes/pull/90033), [@apelisse](https://github.com/apelisse)) [SIG API Machinery and Testing]
- The `MutatingWebhookConfiguration` and `ValidatingWebhookConfiguration` APIs have been promoted to `admissionregistration.k8s.io/v1`:
  - `failurePolicy` default changed from `Ignore` to `Fail` for v1
  - `matchPolicy` default changed from `Exact` to `Equivalent` for v1
  - `timeout` default changed from `30s` to `10s` for v1
  - `sideEffects` default value is removed, and the field made required, and only `None` and `NoneOnDryRun` are permitted for v1
  - `admissionReviewVersions` default value is removed and the field made required for v1 (supported versions for AdmissionReview are `v1` and `v1beta1`)
  - The `name` field for specified webhooks must be unique for `MutatingWebhookConfiguration` and `ValidatingWebhookConfiguration` objects created via `admissionregistration.k8s.io/v1`
- The `AdmissionReview` API sent to and received from admission webhooks has been promoted to `admission.k8s.io/v1`. Webhooks can specify a preference for receiving `v1` AdmissionReview objects with `admissionReviewVersions: ["v1","v1beta1"]`, and must respond with an API object in the same `apiVersion` they are sent. When webhooks use `admission.k8s.io/v1`, the following additional validation is performed on their responses:
  - `response.patch` and `response.patchType` are not permitted from validating admission webhooks
  - `apiVersion: "admission.k8s.io/v1"` is required
  - `kind: "AdmissionReview"` is required
  - `response.uid: "<value of request.uid>"` is required
  - `response.patchType: "JSONPatch"` is required (if `response.patch` is set) ([#80231](https://github.com/kubernetes/kubernetes/pull/80231), [@liggitt](https://github.com/liggitt))
- The `CustomResourceDefinition` API type is promoted to `apiextensions.k8s.io/v1` with the following changes:
  - Use of the new `default` feature in validation schemas is limited to v1
  - `spec.scope` is no longer defaulted to `Namespaced` and must be explicitly specified
  - `spec.version` is removed in v1; use `spec.versions` instead
  - `spec.validation` is removed in v1; use `spec.versions[*].schema` instead
  - `spec.subresources` is removed in v1; use `spec.versions[*].subresources` instead
  - `spec.additionalPrinterColumns` is removed in v1; use `spec.versions[*].additionalPrinterColumns` instead
  - `spec.conversion.webhookClientConfig` is moved to `spec.conversion.webhook.clientConfig` in v1
  - `spec.conversion.conversionReviewVersions` is moved to `spec.conversion.webhook.conversionReviewVersions` in v1
  - `spec.versions[*].schema.openAPIV3Schema` is now required when creating v1 CustomResourceDefinitions
  - `spec.preserveUnknownFields: true` is disallowed when creating v1 CustomResourceDefinitions; it must be specified within schema definitions as `x-kubernetes-preserve-unknown-fields: true`
  - In `additionalPrinterColumns` items, the `JSONPath` field was renamed to `jsonPath` in v1 (fixes https://github.com/kubernetes/kubernetes/issues/66531)
    The `apiextensions.k8s.io/v1beta1` version of `CustomResourceDefinition` is deprecated and will no longer be served in v1.19. ([#79604](https://github.com/kubernetes/kubernetes/pull/79604), [@liggitt](https://github.com/liggitt))
- The `ConversionReview` API sent to and received from custom resource CustomResourceDefinition conversion webhooks has been promoted to `apiextensions.k8s.io/v1`. CustomResourceDefinition conversion webhooks can now indicate they support receiving and responding with `ConversionReview` API objects in the `apiextensions.k8s.io/v1` version by including `v1` in the `conversionReviewVersions` list in their CustomResourceDefinition. Conversion webhooks must respond with a ConversionReview object in the same apiVersion they receive. `apiextensions.k8s.io/v1` `ConversionReview` responses must specify a `response.uid` that matches the `request.uid` of the object they were sent. ([#81476](https://github.com/kubernetes/kubernetes/pull/81476), [@liggitt](https://github.com/liggitt))
- Add scheduling support for RuntimeClasses. RuntimeClasses can now specify nodeSelector constraints & tolerations, which are merged into the PodSpec for pods using that RuntimeClass. ([#80825](https://github.com/kubernetes/kubernetes/pull/80825), [@tallclair](https://github.com/tallclair))
- Kubelet should now more reliably report the same primary node IP even if the set of node IPs reported by the CloudProvider changes. ([#79391](https://github.com/kubernetes/kubernetes/pull/79391), [@danwinship](https://github.com/danwinship))
- Omit nil or empty field when calculating container hash value to avoid hash changed. For a new field with a non-nil default value in the container spec, the hash would still get changed. ([#57741](https://github.com/kubernetes/kubernetes/pull/57741), [@dixudx](https://github.com/dixudx))
- Property `conditions` in `apiextensions.v1beta1.CustomResourceDefinitionStatus` and `apiextensions.v1.CustomResourceDefinitionStatus` is now optional instead of required. ([#64996](https://github.com/kubernetes/kubernetes/pull/64996), [@roycaihw](https://github.com/roycaihw))
- When the status of a CustomResourceDefinition condition changes, its corresponding `lastTransitionTime` is now updated. ([#69655](https://github.com/kubernetes/kubernetes/pull/69655), [@CaoShuFeng](https://github.com/CaoShuFeng))

**New Feature:**

- Adds the ability to load kubeconfig from a dictionary [kubernetes-client/python-base#195](https://github.com/kubernetes-client/python-base/pull/195)
- Allow incluster to accept pass-in config [kubernetes-client/python-base#193](https://github.com/kubernetes-client/python-base/pull/193)
- Set expiration on token of incluster config and reload the token if it expires [kubernetes-client/python-base#191](https://github.com/kubernetes-client/python-base/pull/191)

**Bug Fix:**

- Fixes a bug in loading kubeconfig when there are no users in the config [kubernetes-client/python-base#198](https://github.com/kubernetes-client/python-base/pull/198)
- Retry expired watches [kubernetes-client/python-base#133](https://github.com/kubernetes-client/python-base/pull/133)

- Python 3.7 support
- Update to Kubernetes 1.10.10 API

**Breaking Change:**
- **ACTION REQUIRED** Rename the currently being-used `async` parameter to `async_req` to support Python 3.7 because `async` is a reserved keyword in Python 3.7 [kubernetes-client/gen#67](https://github.com/kubernetes-client/gen/pull/67)
- **NOTE** Python 3.7 was released after v6.0.0 release. It's not necessary to upgrade your client to v6.1.0 if you do not use Python 3.7+.

**API change:**
- Add custom object status and scale api kubernetes-client/gen#72

# v8.0.0
**New Feature:**
- Add utility to create API resource from yaml file [kubernetes-client/python#655](https://github.com/kubernetes-client/python/pull/655)

  [kubernetes-client/python-base#86](https://github.com/kubernetes-client/python-base/pull/86)

**API Change:**
- Upon receiving a LIST request with expired continue token, the apiserver now returns a continue token together with the 410 "the from parameter is too old " error. If the client does not care about getting a list from a consistent snapshot, the client can use this token to continue listing from the next key, but the returned chunk will be from the latest snapshot [kubernetes/kubernetes#67284](https://github.com/kubernetes/kubernetes/pull/67284)
- Introduces autoscaling/v2beta2 and custom\_metrics/v1beta2, which implement metric selectors for Object and Pods metrics, as well as allowing AverageValue targets on Objects, similar to External metrics [kubernetes/kubernetes#64097](https://github.com/kubernetes/kubernetes/pull/64097)

  that may be used to run containers in the cluster. Pods can select a
  RunitmeClass to use via the RuntimeClassName field. This feature is in alpha,
  and the RuntimeClass feature gate must be enabled in order to use it [kubernetes/kubernetes#67737](https://github.com/kubernetes/kubernetes/pull/67737)
- The PodShareProcessNamespace feature to configure PID namespace sharing within
  a pod has been promoted to beta [kubernetes/kubernetes#66507](https://github.com/kubernetes/kubernetes/pull/66507)
- To address the possibility dry-run requests overwhelming admission webhooks that rely on side effects and a reconciliation mechanism, a new field is being added to admissionregistration.k8s.io/v1beta1.ValidatingWebhookConfiguration and admissionregistration.k8s.io/v1beta1.MutatingWebhookConfiguration so that webhooks can explicitly register as having dry-run support. If a dry-run request is made on a resource that triggers a non dry-run supporting webhook, the request will be completely rejected, with "400: Bad Request". Additionally, a new field is being added to the admission.k8s.io/v1beta1.AdmissionReview API object, exposing to webhooks whether or not the request being reviewed is a dry-run [kubernetes/kubernetes#66936](https://github.com/kubernetes/kubernetes/pull/66936)
- Add custom object status and scale api [kubernetes-client/gen#72](https://github.com/kubernetes-client/gen/pull/72)
