Almost all products got their version bumped up on the websites, but they are not available on the market at all (at least in my country; just asked my dealer for a TL-SG108PE v2, which he didn't even heard of until I asked for). Probably those new versions just will just have the new TP-Link logo on the box and a web UI with new look & feel, which was introduced recently due to the 20-year jubilee of TP-Link. For any other differences we probably will have to wait until those successor versions will hit the market. I hope that future software for newer versions will be made available to older hardware, too.
