Release notes

Overview

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

Release overview

watchOS 3.2.3 was released on July 19, 2017. Apple's consumer entry remains a general maintenance statement, while the advisory identifies repairs in communications, kernel, libraries, interprocess services, and Wi-Fi.[1][2][3]

Evidence boundary

The source does not name ordinary bug fixes, so none is inferred. The Wi-Fi claim is limited to the vulnerability and hardware scope stated by Apple rather than generalized into a connectivity improvement.[4][3]
