Release notes

Overview

Editorial synthesis with inline references and a source ledger when citations are available.

Release overview

The existing local tvOS 13.4.5 record has an audited public appearance dated May 20, 2020. Apple's cumulative consumer page confirms the version but gives no date, while Apple's security advisory labels tvOS 13.4.5 as released May 26, creating an unresolved six-day source conflict.[1][2]

Evidence boundary

This bundle preserves the audited local route and event target instead of rewriting chronology. It explicitly records the first-party date disagreement, uses Apple's advisory for the security content, and makes no claim that resolves which date should be canonical.[3][2]
