Release notes
What changed
Original editorial synthesis. Linked references appear with the claims they support and in the source ledger.
Archived Apple note state
Internet Archive preserved Apple's iPadOS 26.4 beta documentation during the interval after Beta 1 and before Beta 2. The raw DocC payload identifies itself as the 26.4 beta notes and contains 12 structured items represented here.[1]
Documented Beta 1 inventory
The archived state covers Background Assets APIs and limitations, memory protection, RCS encryption testing, networking, StoreKit, SwiftUI, UIKit, Feedback, external media, and Reality Composer. Items are separated below so known issues, resolved issues, new APIs, and test-only capabilities remain distinguishable.[1]
Attribution boundary
This page records the first retained 26.4 note state, not a claim that every item debuted at the exact seed publication time. The raw capture predates Beta 2, which makes Beta 1 the only intervening 26.4 milestone; later beta, RC, and Public material is not copied backward.[1]
