Release notes

Overview

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

Release overview

tvOS 11.1 was released on October 31, 2017 with the Apple TV app in Norway and Sweden, general performance and stability improvements, and security repairs across text, kernel, archives, WebKit, and model-scoped Wi-Fi behavior.[1][2][3]

Evidence boundary

Apple does not enumerate the performance and stability work, so it remains a general entry. KRACK statements retain the advisory's distinction between Apple TV 4K and Apple TV (4th generation).[3][4]
