 ## [Unreleased]
 
+### Changed
+- New installs now start with the minimal workspace layout (theme already follows the system). Anyone who previously toggled the mode keeps their stored setting.
+- Whole-codebase restructuring pass (internal, no behavior change): the remote-daemon stack moved out of `Workspace.swift`, browser data-import out of `BrowserPanel.swift`, v2 browser automation out of `TerminalController.swift`, UI-test harnesses out of `AppDelegate.swift`, and `TabManager`/`GhosttyNSView`/`ContentView` split into per-concern files — the largest source files shrank by 3,000–5,000 lines each, cutting incremental build times. The copy-pasted v1 telemetry-handler skeleton, agent-wrapper commands (Go and Swift), and boilerplate settings accessors were each collapsed onto single shared implementations.
+
+### Fixed
+- Port telemetry from shells and agents (`report_ports`, `clear_ports`) no longer blocks on the app's main thread, so a busy UI can't stall the socket.
+- Notifications in multi-window sessions now respect which window owns the tab: the tab in front of you no longer fires an external banner, and background tabs in other windows are no longer misjudged as focused.
+- Closing a pane now cleans up everything closing a single surface does — stale unread badges and leaked per-panel state are gone.
+- `send`/`send_surface` now refresh the terminal after injecting text (parity with v2 `surface.send_text`), so socket-driven agents see output without a focus change.
+- CI: removed a stale release guard that blocked all PRs after the first single-lane auto-ship, and fixed a startup race plus re-run churn in the typing-lag regression job.
