This is actually the 4th Apple Polishing Cloth. Here are all the variants I know:
* Original one (reference size)
* New one (reference size; softer/thinner)
* Apple Vision Pro (slightly smaller, square, different colour)
* Nanotexture Display (much smaller, rectangular)
I guess anyone wanting to polish their iPhone 4 is SOL.
The new cloth is different. It's softer and thinner, but the same size.
If you want to spend 12 minutes on what changed, AppleInsider made a video: https://www.youtube.com/watch?v=iL-4kCkvEvQ
