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.
Do you have a source link for this? I don't want to sound snarky, but this list doesn't make sense to me.
Offline support has been available (and buggy, YMMV) for a long time.
Web Push has been available since 16.4 (with a lot of caveats)
I haven't heard anything about installation (but I may have missed something)
