Release notes

What changed

Original editorial synthesis. Linked references appear with the claims they support and in the source ledger.

Release identity

iPadOS 26 Beta 5 appeared on 2025-08-05. Its primary build is 23A5308g; that build identifier is scoped to iPadOS even when the same alphanumeric value also appeared on another Apple platform.[1]

What changed at this milestone

The adjacent preserved Apple Developer snapshots support 10 milestone-specific items for this seed. These are deltas visible at this point in the prerelease cycle, not a cumulative copy of the eventual public release notes.[2][3][4][5][6][7][8][9][10][11]

How to read these notes

Apple’s iOS and iPadOS 26 developer-notes page was updated throughout the beta cycle. This article uses preserved snapshots to isolate what the retained evidence supports at Beta 5; it does not project the final public notes backward or describe an unlisted revision as a bug or security fix.[12][13]
