    - update to 23.6.0:
      * Omits alpha-level enums from the static openapi file captured in api/openapi-spec
      * Fixes a regression in v1beta1 PodDisruptionBudget handling of "strategic
        merge patch"-type API requests for the `selector` field. Prior to 1.21,
        these requests would merge `matchLabels` content and replace
        `matchExpressions` content. In 1.21, patch requests touching the `selector`
        field started replacing the entire selector. This is consistent with
        server-side apply and the v1 PodDisruptionBudget behavior, but should not
        have been changed for v1beta1.
