Agent History Opens Faster in VS Code: List Loads in 0.1 Seconds
VS Code 1.139.0 Stable, released on September 23, 2026, cut the initial load time for a list of 645 agent sessions from 1,3 to 0,1 seconds. The release also runs agent sessions in Dev Containers locally and on remote hosts.

Previously, the agent host opened the database for every conversation to build the list. It now keeps lightweight session and chat metadata in a central catalog, while migrating old sessions in the background: refreshing the list in the same measurement took 0,15 seconds instead of 0,6. The difference will be smaller for short lists.
Dev Containers go further. Previously, agent sessions in a Dev Container worked only with local folders. VS Code now runs them for projects over SSH, Tunnel, and WSL as well: enable `chat.agentHost.devContainer.enabled`, then choose Use Dev Container from the Agents Window folder menu. On a remote host, you need a Dev Container configuration and Docker. The feature is rolling out gradually, but the setting can already be enabled manually.
History is easier to manage. Agents Window now has Compact View, and you can rename a session or nested chat by double-clicking, from the context menu, or with F2. An installed editor updates through Check for Updates.
Dev Container sessions are rolling out gradually, but the setting can already be enabled manually.
