Pause/Resume for agents — The agent can now be paused and resumed, which means it can handle long-running tools (model training, large database queries, scripts that take hours) without hitting timeout issues. This was a known bug in earlier versions.
Permission controls for tool calls — runcell now asks for your approval before executing actions like running code, bash commands, or installing dependencies. This gives you more control over what the agent does. It's fully configurable — you can choose between manual approval or letting it act directly.
New model support — Opus 4.6, Codex 5.2, and Kimi 2.5 are now available.
