I haven't heard about any new release of the APS-C in E mount lately. Which model is the latest and when it was released?
I believe the ZV-E10 is their latest release... approx. the middle of 2021. Don't know a whole lot about it, but it appears to be a fairly video-centric camera... for vloggers more than for photographers.
Prior to that the a6100 and a6600 were both introduced around the middle of 2019. As with all the a6000-series they aree more still photography-oriented models, though they are also capable of shooting video. The a6100 is a relatively entry-level (update to the a6000), while the a6600 is top-of-the-line (superseding the a6500). The 6 month older a6400 is also offered (replaced the a6300), with price and specs that slot in between the other two models.
All four of these are 24MP APS-C cameras. It is price and other features they offer that set them apart from each other.
ZV-E10... $698
a6100..... $748
a6400..... $898
a6600... $1398
You can see quick comparisons of the different models here (I use an a6600 to a6400 example, which you can change around to compare other models if you wish):

But, for example, the a6600 and a6400 have a higher resolution electronic viewfinder (EVF) than the a6100, while the ZV-E10 doesn't have an EVF at all. It only has the screen on the rear for composition.
And, a major difference between the a6600 and the a6400 is that the more expensive, top-of-the-line model has IBIS or "in body image stabilization". All the other APS-C Sony models lack IBIS (ZV-E10 has digital stabilization for video only).
Sometimes you need to read between the lines a little:
The a6600 also appears more power efficient, getting nearly 2X the number of shots out of a battery charge compared to the a6400. However, there are two reasons for this. First, the a6600 uses a larger, higher capacity battery. However, it also doesn't have a built-in flash, while the a6400 does. When it's done on a camera that has a built-in flash, the standardized CIPA testing requires half the shots to use the flash. That's a heavy power drain on the battery. As a result, a camera that doesn't have a built-in flash will always appear more power efficient than a similar model with a built-in flash, all other things being equal. It further helps the a6600 stand out that it uses a higher capacity battery.

EDIT:
I completely disagree with several previous responses... APS-C format remains popular and will continue to be so in the future. It is only on blogs and forums such as UHH, where relatively serious amateurs and some pro shooters gather and chat, that full frame is treated like the be-all and end-all (and even here that's not everyone's opinion).
While full frame has grown in popularity, the vast majority of cameras being sold today are still NOT full frame. Full frame is still a relatively small niche (as are even larger medium format and even smaller Micro 4/3).
In 2021 the top ten cameras sold in Japan didn't include even a single full frame model. Nine were APS-C and one was M4/3. Interestingly, all ten were mirrorless! Not a single DSLR! While this top ten list is a snapshot of a specific camera market, we simply don't have full data on the rest of the world yet and there are certainly some regional differences, but when it comes to sensor format it's not likely to be all that different from Japan. (Also, because of the way the top ten list was compiled three camera models appear twice, each being sold in choice of two or more different kits.)
APS-C are a comfortable and poplulare compromise that's more than capable of meeting most peoples' needs. It is pretty much only pixel-peepers like us, judging the detail in our images magnified on our computer screens waaaay larger than we'll ever print them, who are inclined to spend a whole lot more for bigger heavier full frame cameras and much bigger, heavier full frame-capable lenses. The rest of the world and the majority of buyers are quite happy with their APS-C cameras!
