This upgrade spans multiple minor versions, from 0.17.0 to 0.21.0, which correspond to updates for Kubernetes versions 1.17 through 1.21. The most significant breaking change is the removal of a deprecated RBAC API version.

Breaking Changes:

• RBAC API Removal: The rbac.authorization.k8s.io/v1alpha1 and rbac.authorization.k8s.io/v1beta1 API versions were removed in Kubernetes 1.20 (client version 0.20.0). Code using these API versions must be updated to use rbac.authorization.k8s.io/v1.

Deprecation Warnings:

• Several v1beta1 APIs for resources like Ingress, CustomResourceDefinition, and ValidatingWebhookConfiguration are deprecated and will be removed in Kubernetes 1.22 (the version after this upgrade). While not breaking in 0.21.0, applications using them should plan for migration.

Source: Kubernetes Changelogs

Recommendation: Before merging, audit your codebase for any usage of the removed v1alpha1 and v1beta1 RBAC APIs and update them to the stable v1 API. It is also highly recommended to review usage of other deprecated v1beta1 APIs to prepare for future upgrades.
