Overview

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

Release overview

tvOS 14.3 was released on December 14, 2020 with a dedicated Apple TV+ tab, Apple Fitness+, Apple One integration, and security repairs across audio, fonts, images, model processing, web storage, WebRTC, and Wi-Fi.[1][2]

Evidence boundary

Apple notes that its TV app, Fitness+, and Apple One availability varied by country or region. The page retains those qualifications and does not import features from later tvOS releases.[3][4]
