Release notes

What changed

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

Preserved release-note evidence

The reader-facing archive identifies the retained source document as “iOS & iPadOS 15 Beta Release Notes.” This iOS overlay selects 16 substantive records from the 146-record initial state.[1]

How this milestone is isolated

This is a representative baseline rather than an exhaustive conversion of all 146 retained records. A later cumulative snapshot is used only when its section heading names this exact beta.[2]

Platform scope

Items expressly limited to iPad, iPadOS, multiwindow iPad behavior, or iPad hardware-keyboard interfaces are excluded. Shared framework behavior and explicitly iPhone or iOS changes are retained.[3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]

Editorial boundary

The page uses original synthesis and issue-ID locators. It does not reproduce Apple's list prose, infer a build number, project generic cumulative notes into a beta, or treat TestFlight and release identity as user-facing changes. Apple's beta guidance describes these seeds as prerelease software.[19][20]
