Just got a new Logitech Combo Touch case for my iPad, and I noticed a few subtle changes compared to an older revision.
First, they changed the speaker holes to be individual holes aligned with the iPad's grille rather than one long line:
This was probably to address the stretching issue where many of these cases stretched and sagged along the speaker holes because of the thin TPU material. Hopefully this new design will be more durable with the added material along the speaker area.
The second change is with the icons on the volume keys:
Previously there were defined plus and minus symbols, but since Apple introduced adaptive volume buttons their functions are no longer fixed so now we have generic button outlines.
