• PHP-aggedon: OpenAI’s GPT-5.6 Sol and Google’s Wiz, with its Atlas agent and Gemini 4 Argon, found the decades-old flaws, which AI makes both findable and newly easy to exploit, so the race is on to patch tens of millions of sites (techcrunch.com/2026/10/21/php-armageddon-opena…) (TechCrunch)

• Anthropic unveils Claude Duet, a proactive agent app on iOS, Android, and the web that works in the background, in research preview for US Pro and Max users (claude.com/resources/articles/claude-duet) (Claude)
