 ### Authorization mode configuration {#choice-of-authz-config}
 
 You can configure the Kubernetes API server's authorizer chain using either
-[command line arguments](#using-flags-for-your-authorization-module) only or, as a beta feature,
-using a [configuration file](#using-configuration-file-for-authorization).
+a [configuration file](#using-configuration-file-for-authorization) only or
+[command line arguments](#using-flags-for-your-authorization-module).
 
 You have to pick one of the two configuration approaches; setting both `--authorization-config`
 path and configuring an authorization webhook using the `--authorization-mode` and
 `--authorization-webhook-*` command line arguments is not allowed.
 If you try this, the API server reports an error message during startup, then exits immediately.

-* `--authorization-mode=Node` (Node authorizer)
-* `--authorization-mode=Webhook` (Webhook authorization mode)
-* `--authorization-mode=AlwaysAllow` (always allows requests; carries [security risks](#warning-always-allow))
-* `--authorization-mode=AlwaysDeny` (always denies requests)
-
-You can choose more than one authorization mode; for example:
-`--authorization-mode=Node,RBAC,Webhook`

-Kubernetes checks authorization modules based on the order that you specify them
-on the API server's command line, so an earlier module has higher priority to allow
