Release Notes
Agents Agent host The agent host lets you connect to the same agent session from multiple VS Code windows. It runs agent harnesses in a dedicated process based on the Agent Host Protocol (AHP). The agent host's Copilot agent is powered by the Copilot SDK, which aligns the agent's behavior and functionality with the Copilot CLI, the standalone GitHub Copilot app, and other Copilot products. We're actively developing the agent host. The following screenshot shows the Copilot harness selec... Grid layout for chats in a session Keep related conversations visible by arranging chats in horizontal or vertical groups. Drag chats or subagent chats into a group to compare results or monitor work side by side. VS Code restores the chat-group layout and focus when you return to the session or reload the window. Create a side chat to open a new conversation beside the current chat. Drag and drop a subagent chat into a group to view it side by side with the current chat. You can also Alt+select a chat in the Chats picker to open it to the side. Improvements to the side pane layout Settings: setting(sessions.layout.singlePaneDetailPanel) and setting(workbench.editor.showTabs) The single-pane layout keeps session details and editors in a shared tab bar next to chat. This release makes the layout easier to control: The layout follows the setting(workbench.editor.showTabs) setting. Multiple tabs remain visible, while the single and none values use a compact single-title header. Text file editors use the same header structure as the Changes editor, with file breadcrumbs in the header. The side pane... Prompt timeline Setting: setting(sessions.chatTimeline.display) Long agent sessions can make it difficult to find earlier prompts and identify which ones changed files. The Agents window includes a timeline in the transcript gutter. Each dot represents one of your prompts, and the highlighted dot marks your current position. Hover over the timeline to view your prompts, then select one to jump to it. For prompts that changed files, the list shows the number of lines added and removed and lets you open the changes directly for review. Use the setting(sessions.chatTimeline.disp... Chat Find in chat Finding information from earlier in a long conversation previously required scrolling through the transcript. Use kb(workbench.action.chat.find) to search conversations in the Chat view, chat editors, and the Agents window. Search includes the entire conversation, even content that is not currently rendered on screen. As you move between matches, VS Code scrolls each match into view and expands a collapsed work summary if it contains the match. You can also match case, match whole words, or use regular expressions.
