Changelog since v1.16.0-alpha.3

Action Required

• scheduler.alpha.kubernetes.io/critical-pod annotation is removed. Pod priority (spec.priorityClassName) should be used instead to mark pods as critical. Action required! (#80342, @draveness)
• Removed cadvisor metric labels pod_name and container_name to match instrumentation guidelines. (#80376, @ehashman)
  • Action required: any Prometheus queries that match pod_name and container_name labels (e.g. cadvisor or kubelet probe metrics) must be updated to use pod and container instead.
• Remove DirectCodecFactory(replace with serializer.WithoutConversionCodecFactory), DirectEncoder(replace with runtime.WithVersionEncoder) and DirectDecoder(replace with runtime.WithoutVersionDecoder). action required (#79263, @draveness)

Other notable changes

• fix: detach azure disk issue using dangling error (#81266, @andyzhangx)
• 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.uidthat matches the request.uid of the object they were sent. (#81476, @liggitt)
• The CustomResourceDefinition API type is promoted to apiextensions.k8s.io/v1 with the following changes: (#79604, @liggitt)
  * 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; use spec.versions instead
  * spec.validation is removed; use spec.versions[*].schema instead
  * spec.subresources is removed; use spec.versions[*].subresources instead
  * spec.additionalPrinterColumns is removed; use spec.versions[*].additionalPrinterColumns instead
  * spec.conversion.webhookClientConfig is moved to spec.conversion.webhook.clientConfig
  * spec.conversion.conversionReviewVersions is moved to spec.conversion.webhook.conversionReviewVersions
  * 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 (fixes https://github.com/kubernetes/kubernetes/issues/66531)
