And so the CJ1000 also got a new designation?
Don't know, haven't seen it, but it should.
The thing is that CJxxxx was more like a code name of development program. All ACAE's engine eventually would be labeled in this way, 1st letter represents A(CEA), 2nd is E(ngine), 3rd is type F(an)/P(ropeller)/S(haft), 4 following digits should be class of power or force(3500 => 3500kw or 350kn or 35 ton-force).
Maybe because CJ-1000A model was not shown in Zhuhai 2018? If it was I would assume it will be labeled in the same manner.
[Correction] It should be AECC (Aero Engine Corporation of China) instead of ACEA. AECC was founded May 2016 before CJ-1000A was last exhibited during 2012 Zhuhai airshow.
If it does eventually get a product number, it would probably be AEF1400 because the official spec is 14000kgf.

Just since we tangled this issue in the new naval fighter thread concerning a possible FC-31V3, can anyone give a summary of the WS-13's status??
From what is said, the WS-13 is officially ready, even in production but IMO not confirmed or even unlikely. So to admit, the WS-13 is a mystery like the similar rated WP-14 Kunlun once. There are reports that a FC-1/JF-17 flew with it in 2010/11 ... there are even reports via Jane's that current production models are using it already but I don't think so. The next we know that the FC-31V1 flew with two different engines in 2014, one said to be a WS-13 replacing one RD-93, but again nothing confirmed.
Did I miss anything?

Unsure of its credibility, but would be significant news regarding the WS-15 if true.
Could someone do a comprehensive translation/summary of the two posters below? One of them mentions that three batches of the WS-15 have been produced or are in production and that the third batch has won an award. Perhaps this implies that batches 01 & 02 have been built and thoroughly tested.

Rough translation of texts that you underlined (and not underlined but related)
First photo:
- XX15 engine inner and outer passage/duct matching optimization.
- XX20 engine fan blade vibration reduction.
- (not underlined) XX15 engine improvement batch full engine (not just core) dynamic (动力学) characteristic, abnormal (异常) load analysis and structure improvement/optimization according to the analysis.
- Intercooling gas turbine dynamic simulation and application.
- Axial symmetric TVC nuzzle A8 actuation system load distribution analysis.
- Research of key assembly technique and method of engine core of XX15 (improvement batch).
- A type of combustion chamber design.
- Design of inlet duct of 3rd batch XX15 based on MBD (massive diffusion bonding).
- Two stage high pressure turbine cooling blade of high thrust medium bypass ratio engine.
- Medium bypass engine. What is this? WS-10 and 15 are low bypass, WS-20 is high bypass.
- What does it mean by cooling blade (冷却叶片)? Should it be blade cooling (叶片冷却) instead?
- Research into the impact of surface material characteristic of an important engine type to stealthy coating.
Probably WS-20? If it's CFM56-ish (BPR 4-6) as rumoured it's what I'd nowadays describe as a medium bypass ratio engine - high bypass these days is >8 really (CJ-1000A, for example). With a two-stage HPT it's almost certainly not going to be the WS-15, which will probably adopt a single-stage HPT for weight and inertia reasons.
EDIT: actually, the two-stage HPT excludes the WS-20 too, doesn't it? The WS-10 core has a single-stage HPT as well. Hmm...
That would be my guess. Or "cooled blade"?
