Release notes

Overview

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

Apple’s first iPhone update focused on web-content security. It corrected cross-site access through redirected windows, unsafe regular-expression processing, injected XMLHttpRequest headers, deceptive internationalized domain names, and memory corruption while rendering framesets.^[1]

Apple distributed the package only through iTunes and identified the resulting version as 1.0.1. Its historical security index dates the release to July 31, 2007; no broader consumer feature list survives in Apple’s bulletin.^[2]^[3]
