Quite a lot. The headlines are: 

Three new add-ons for Limitless and Clarity — a Camera Guard that covers the whole camera bump, a Camera Kickstand with a machined metal hinge, and CNC machined aluminium Metal Buttons. 

Super Thin is back, rebuilt with an all-new co-moulded construction and a seamless side wall. 

Our magnets have been completely rebuilt and hold significantly more strongly than last year. 

Limitless is colour matched to the new iPhone colours for the first time, and the accessories match too. 

And we have made Limitless for the folding iPhone, which is the most complex case we have ever engineered.
