Claude Code ships features every day — new tools, modes, integrations, and workflows. whats-new brings feature discovery into your session so you never have to leave your terminal to learn what's available. Get a feature of the day when you start a session, describe what you're working on to find relevant capabilities, or browse the full catalog of 50+ features across 10 categories. It's like having a teammate who's read every changelog and knows exactly when to mention the right feature.
