   Users that want to keep PulseAudio will want to set `services.pipewire.enable = false;` and `hardware.pulseaudio.enable = true;`.
   There is currently no plan to fully deprecate and remove PulseAudio, however, PipeWire should generally be preferred for new installs.
 
+- The Rust rewrite of the `switch-to-configuration` program is now used for system activation by default.
+  If you experience any issues, please report them.
+  The original Perl script can still be used for now by setting `system.switch.enableNg` to `false`.

         This is good for image based appliances where updates are handled
         outside the image. Reducing features makes the image lighter and
