As far as I can see based on pwa.gripe data, between 26.3 (my version) and the newcoming 26.4 Safari on iOS gains support for five new APIs:

— Offline support

— Media capture

— Picture-in-picture

— Storage

— Speech synthesis

As well as five more APIs with caveats:

— Installation

— Notifications

— Web Push

— Barcode detection

— Speech recognition

Even taking into account that it also evidently loses support for one (audio session; I wonder if that that has to do with potential for fingerprinting), framing this feature differential between two minor(!) releases as “intentional crippling of Mobile Safari continues” strikes me as somewhat loaded.
