Features
- Copilot chats run on the GitHub Copilot SDK instead of ACP (#1714).
- Stacked PR lanes are grouped in order in the Work page and joined with a rail (#1722).
- A compact new-lane composer with inline branch pickers (#1721).
- Elements you inspect in the browser tell the agent their HTML, CSS and source file (#1719).
Speed
- ADE opens faster by reusing compiled code from the last launch (#1743).
- The background service starts faster the same way (#1744).
- Finding slash commands no longer freezes the background service on large skill folders (#1737).
Sync & multi-machine reliability
- A chat you just started on another machine shows as working right away, not Done (#1733).
- A closed Tools pane stays closed while a shell on another machine prints (#1742).
- Lane “new chat” buttons open on that exact lane and machine (#1720).
- Deleting a lane on another machine shows the same progress overlay as a local delete (#1724).
- A machine that isn’t reconnecting automatically says so instead of just “Not connected” (#1739).
- Sync status right after the background service starts says ready when it is (#1736).
- Serving a project that follows another machine no longer stops the project that hosts sync (#1735), and a runtime that isn’t allowed to host never claims the sync cluster (#1730).
- Start sync says what’s happening instead of a raw 30-second timeout (#1738).
Fixes
- A resumed subagent stays marked as running (#1713).
- Settings always keeps the sidebar visible and never becomes a project’s start page (#1725).
- Renderer path checks no longer reveal, through symlinks, whether files exist outside allowed folders (#1727).
Diagnostics
- Logged errors group in Sentry by the real error instead of by log event (#1726), and CLI runtime errors keep their stack in the log (#1728).
