Overview

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

iOS 5 reorganized daily interaction around Notification Center, iMessage, Newsstand, Reminders, system-level Twitter support, richer Camera and Photos tools, and broader Mail, Calendar, Game Center, keyboard, and accessibility features.[1][2]

The release also moved setup, software updating, and iTunes synchronization away from a required cable, integrated iCloud services, exposed more than 1,500 developer APIs, and delivered security work spanning credentials, certificate trust, TLS, documents, networking, Safari, and WebKit.[3][4][5][6][7]
