Release notes

Overview

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

iOS 9.1 refined Live Photos so raising or lowering the phone was excluded from a recording and expanded the emoji keyboard with more than 150 Unicode 7.0 and 8.0 characters.[1]

The release also addressed stability, multitasking performance, Calendar, Game Center, Mail, Messages, carrier activation, App Store updates, and a substantial set of published security defects.[2][3][4]
