Release Notes

Agents Run agent sessions in Dev Containers on remote hosts Setting: setting(chat.agentHost.devContainer.enabled) (Agents window only) Let agents build and test your remote project with the right tools and dependencies, without duplicating toolchain setup on your laptop or the remote host. This release extends Dev Container sessions from local folders to projects on SSH, Tunnel, and WSL hosts. To get started, enable setting(chat.agentHost.devContainer.enabled) and select Use Dev Container from the folder menu in the Agents Window. The remote folder must have a supported Dev Cont... Faster session list loading VS Code loads and refreshes large agent session lists faster. The agent host keeps lightweight session and chat metadata in a central catalog instead of opening every conversation database each time the list is built. Full conversation content remains isolated in the individual session and chat databases. The improvement grows with the number of sessions because the previous approach did work in proportion to your session count. Measured with around 645 sessions on a development machine: | Operation | Before | After | Improvement | | ---------- | ------ |... Compact sessions list Fit more sessions in the sessions list by enabling Compact View in the sessions list view of the Agents Window. Compact rows show the session title at rest and reveal workspace details when you hover over or focus the row. A row expands when the session needs input or approval, so these requests remain visible. Progress also appears on the row for the chat that owns the work. When you collapse a session, the parent row summarizes progress from its hidden chats. Filter empty session groups Disable Empty Groups from Filter Sessions to hide empty custom groups and the empty Chats section. This preference is stored in your profile and resets with the other sessions list filters. Rename sessions and chats in place Rename a session or nested chat directly in the sessions list. Double-click its title, use the Rename context menu action, or focus the row and press kb(sessions.sessionHeader.rename) for a session or kb(sessions.chatCompositeBar.renameChat) for a nested chat. Inline validation prevents blank titles, and canceling restores the previous title. Choose how chats appear in a session (Preview) Setting: setting(sessions.showChatTabs) (Agents window only) An agent session can contain multiple chats, each representing a different conversation or context. When a session contains multiple chats, choose the presentation that best fits your workflow from the session header menu: Multiple shows each chat on its own tab. Single shows only the active chat and hides the tab bar. Switching presentations preserves y...
