2.16.0 September 22, 2026 Windows Subsystem for Linux, Office attachments, and live subagent cards Connect to a Windows Subsystem for Linux distribution from Application Settings, and drop Word, Excel, and PowerPoint files straight into a prompt.

Subagent invocations now appear as dedicated cards in the conversation stream with live running, waiting, and completed status, a hover control to stop a running subagent, and one-click navigation to its conversation in the side pane. Prompt actions in interactive widgets and HTML artifacts now fill in and focus the message box instead of sending automatically, so you can review or edit the prompt before submitting it. Right-click an image in an attachment, a preview modal, or an earlier message to Copy Image or Save Image. SVG images can now be copied to the clipboard and pasted into other applications. The loading indicator now shows what the agent is doing while it prepares a response, including tool initialization progress and a live countdown with attempt count when a model request is retried.

Application keyboard shortcuts now take priority over web previews, so shortcuts keep working while a preview has focus. The Confirm Undo dialog
