Release notes

What changed

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

First iOS 5.1 developer seed

Contemporaneous reporting identifies the first 5.1 beta on November 28, 2011. A preserved three-page Apple-authored PDF provides the detailed milestone state.[1][2]

Selected developer-note state

Twelve records capture API behavior, current limitations, and one explicit Newsstand repair. Ten unmarked or explicitly older states are labeled cumulative context; the peer-to-peer default and marked Newsstand repair remain milestone deltas. Three cumulative records concern the accompanying Xcode and developer-tools environment, so they are retained as host-tool context rather than on-device iOS behavior. This is a selected view rather than a transcription of the full document.[3][4][5][6][7][8][9][10][11][12][13][14]

Preservation and authorship

The linked PDF is a third-party preservation copy of Apple developer material. This page uses new prose, retains technical names only for identification, and stays non-indexable until editorial review.[15]
