Overview

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

Release overview

tvOS 13.4 was released on March 24, 2020. Apple's consumer page lists general performance and stability improvements, and its security advisory documents the version's specific system repairs.[1][2]

Evidence boundary

No named consumer-facing feature appears in Apple's 13.4 section. This page preserves that limitation and does not substitute beta notes, community observations, or later 13.4 point-release behavior.[3][4]
