They went cheap with the upgrade here. Nothing really special. They even put back the old Type 360S radar. The Type 345 radar for the HQ-7 is gone now, as the HQ-10 doesn't need it. Under wraps is the Type 344 radar for the main gun, which means its still going to use the same 100mm gun, and the Type 349 for the H/PJ-13. Its probably the Type 349 instead of the 347G, due to the way the covering over the radar suggests a flat face, not a conical one.
The EW units are upgraded though, with the ECM unit now the standard Type 726-3.
The DLS is oddly, the 8x3 unit from the Type 055.
The rear shot is important. But due to the bars of the bridge obstructing the view, its hard to be certain that the opening in the rear might be for a VDS. If that is a VDS, then that's a sizable upgrade and positions the ship for an ASW function.
