They added a small outside fin to the new endplate, similar to that seen on the Mercedes. The wing introduced in China was quite a big change compared to the previous iteration used in Malaysia (Sepang). The endplate is totally different: it no longer has holes in the lower section and features a single rear exit, again as on the Mercedes. The main plane is also different, with a stepped section on the outside (see red arrows).
