How to render a Markdown comment safely in every place it shows up, with one policy for setHTML() and DOMPurify, and Trusted Types to catch code that writes the comment with innerHTML instead.
TOCus is officially out! In AI news, Google announced Gemini 4 Argon, OpenAI had a big DevDay where they announced GPT-6.1 Sol and some bad news for current Pro users, and Anthropic released Claude Sonnet 5.5. Then there's Firefox 157, CSS corner shapes, an open model that finds browser bugs, vertical wrap in Figma, Gemini's text-to-speech models, and JavaScript iterators.
Claude Opus 5.5 led Artificial Analysis' tests. I explain what Jev is, the thing everybody is talking about. OpenAI released GPT-6 Sol and Luna, SpaceXAI introduced Grok 4.7, and Xiaomi's MiMo-V2.6-Pro is now free. Chrome 154 allows embedded frames to resize to fit the page, Lighthouse 13.5 checks support for AI assistants, and Cloudflare added previews for each branch. Google, Anthropic, and OpenAI updated their programming tools, and nine mathematicians will help OpenAI with sharing math research.
Artificial Analysis swapped the tests behind the model table so every score moved, Chrome 153 shipped camera and microphone as real HTML elements, OpenAI launched GPT-6 Astra and published an AI-written Navier-Stokes proof, Claude, ChatGPT, and Grok broke on the same morning, and NVIDIA signed to buy Hugging Face.
Claude Fable 5.1 took the top of the model table, Gemini 3.8 Flash came in as the fastest model on it, Chrome and Firefox both shipped, OpenAI is cutting Cursor off, and Go, Flutter, and Dart join The Brief.
