The release of major version 2.0 for the Kubernetes and Helm providers for HashiCorp Terraform includes significant changes to authentication, a new Terraform SDK upgrade, improved resource consistency with the upstream Kubernetes API, normalized wait conditions across several resources, removal of support for Helm v2, and deprecation of Terraform v0.11. The updates aim to promote explicit declaration of access credentials and improve user experience, particularly for users managing multiple Kubernetes clusters. Users are advised to review the upgrade guides for each provider before upgrading to ensure a smooth transition.
