Well this was our guess from start of the year:
https://www.globalsecurity.org/military/world/china/luyang-iv.htm Luyang IV / Type 052E new radar, new propulsion, and larger displacement.

Pretty sure H2616 is one of the 052D. There are six 726A LCAC in the photo. So
H2616 launched and fitting out as expected
For the 8 that were scheduled for assembly in dry dock, all are now launched except for the 055
For the 4 that are scheduled to start work, one of the 726A LCAC is already launched and in the water
So there should be another two 052D being built somewhere, plus another 726A LCAC, if the image and our guesses at the type were correct.
