Release notes
Editorial synthesis with inline references and a source ledger when citations are available.
iOS 14.5.1 corrected an App Tracking Transparency state problem: people who had disabled and later re-enabled requests could fail to receive tracking prompts from apps.[1]
The security update fixed two WebKit vulnerabilities that could allow code execution through malicious web content. Apple said both issues may have been actively exploited, making this more than a routine prompt-state patch.[2]
