v2.1.1

Released 2026-08-25

Highlights

  • Cancelled remote HTTP calls no longer release their connection-pool slot before the background transport finishes, eliminating an intermittent protocol and routing failure after cancellation.
  • Power-Boost catalog changes are now delivered to active AI sessions through real MCP notifications. The stale state where the UI showed 237 tools while AI remained at 189 is fixed.
  • Two stable compatibility tools provide bounded search over the complete live catalog and safe dispatch to a selected tool, keeping tools reachable even when a client limits direct tools.
  • Concurrent HTTP tool calls no longer queue behind one connection; a bounded persistent connection pool reduces latency.
  • Hanging tool calls are fixed: when an MCP server sends a request to the app (for example ping) it now always gets a reply. Previously such requests went unanswered, the server kept waiting, and the call stayed pending until the 300-second ceiling.
  • When an MCP server stops reading its input, the call now fails with a clear error within the given timeout; previously it could wait forever without ever hitting a timeout.
  • Tool calls with large arguments are noticeably faster: the roughly 12 ms summarisation cost paid on the response path for a 5 MB argument is gone, and the cost no longer depends on input size.

Fixes

  • Backup listing, backup preview, diagnostics ZIP creation and folder launch now run outside the gateway event loop. Large logs or backup histories no longer pause concurrent tool calls, and broken archives no longer fail the entire list.
  • The explicitly selected unsigned packaging mode now completes correctly when Windows Application Control blocks the embedded backend after the shell starts; signed release mode remains strict.
  • Valid JSON-RPC tool calls no longer fall through to HTTP 404 when a connector or reverse proxy rewrites the invocation path after discovery; the same access-key and Origin checks remain enforced.
  • Power-Boost extensions added, updated or removed from a running MCP are now reconciled automatically with the live runtime and tool catalog. Custom gateway ports are discovered from the active instance and settings, with no manual restart required.
  • Remote MCP HTTP errors now include the endpoint, status and bounded response detail without exposing secret query values. A tool call that received an HTTP response is never resent through fallback.
  • Ambiguous remote tool calls are no longer resent through another connection when the socket may have failed after execution, preventing the same action from running twice.
  • The live Tool Calls view now reconciles rows locally instead of issuing three API requests and rerunning history aggregates for every event.
  • Gateway diagnostics show the latest catalog revision and tool count delivered to each AI session; history queries are faster through composite indexes and invalidated caches.
  • Two redundant database reads on every successful tool call were removed; the cached client lookup now actually skips the query it was meant to avoid.

v2.1.0

Released 2026-08-13

Highlights

  • Manual MCP installation now scans first, shows the detected command/package/URL recipe and required fields, and installs only from the reviewed server-side scan record.
  • MCP install, update, repair and rollback flows are now operation-locked and transactional; a failed update automatically restores the last working version.
  • The Windows desktop package is about 74% smaller; unused legacy UI dependencies were removed and startup plus heavy tool-traffic performance was improved.
  • The app and self-update chain is hardened with SHA-256, TLS, size and timeout checks, plus certificate verification for signed packages. This release is unsigned and clearly disclosed on the download card.

Fixes

  • Desktop Commander no longer performs a runtime npx download; it uses the installed package's local executable.
  • The invalid python -m guess for Computer Control OCR was removed; the real Python console_scripts entry point is resolved and verified with initialize/tools-list.
  • URL template values can no longer leak into HTTP headers; private server.json access, DNS rebinding and update-file replacement windows are blocked.
  • Full uninstall can no longer erase a drive root, custom MCP container or unrelated user files; incomplete cleanup is now reported as an error.

v2.0.6

Planned 2026-07-17

Highlights

  • Major performance update: GPU usage is reduced substantially — the dashboard's blur layers and constant animations were streamlined, and the renderer now sleeps while the app waits in the tray.
  • The dashboard no longer stalls under heavy tool-call traffic: call records are written on a background thread, startup is faster, and starting many MCPs at once no longer slows the machine down.

Fixes

  • An unresponsive MCP no longer hangs around for minutes at startup (initialize timeout 120 s → 45 s; genuinely slow servers can still raise it per recipe).
  • The OS "reduce motion" preference now disables all dashboard animations.

v2.0.5

Released 2026-07-09

Highlights

  • Launch update notice: when a new version is available, a 5-second notification appears and it can be installed with one click from Settings.

Fixes

  • "Install and Restart" and other confirmation-gated actions (quit, MCP remove/repair/rollback, backup restore, directory move) no longer silently do nothing: the confirmation now uses an in-app dialog that works reliably inside the desktop shell.
  • Errors from button actions are now surfaced as a visible error notification.

v2.0.4

Released 2026-07-09

Highlights

  • In-app self-update now completes cleanly end to end: the desktop shell also shuts down properly during the update, the installer hits no file-lock conflicts, and the app comes back automatically on the new version.

Fixes

  • Removed the misleading "backend connection lost" error shown during updates; its Retry button can no longer launch a new backend mid-install and corrupt the update.

v2.0.3

Released 2026-07-08

Highlights

  • MCP installs are now resilient to broken dependency updates in community packages: a dependency release that breaks compatibility after the MCP was published is detected, automatically downgraded to the version its developer actually tested, and the install verification is re-run.

Fixes

  • Works independently of the package name and on every system, including machines where uv is unavailable (os error 448); if the repair does not apply, the original error is reported unchanged.

v2.0.2

Released 2026-07-02

Highlights

  • The setup wizard now detects update vs fresh install: updates show a "vX → vY, your data is preserved" welcome and skip already-answered pages.
  • Refreshed UI: consistent content width on every page, a modern menu with an active-page indicator, unified card/button/table styling and keyboard focus outlines.
  • The English UI is now fully English: all remaining strings and backend-generated error messages are produced in the selected language.
  • In-app updates are verified end to end: completion is confirmed via the installer exit code, and failures show the exact reason.

Fixes

  • The setup wizard no longer looks frozen at launch or on "Install": cleanup runs only when needed, with visible progress.
  • The uninstaller now removes everything, including the extracted backend cache (%LOCALAPPDATA%), and shows status text during long steps.
  • The Windows "untrusted mount point (os error 448)" error no longer aborts MCP installs: an existing Python matching the package requirement is used automatically (version-agnostic).

v2.0.1

Released 2026-07-01

Highlights

  • Managed runtimes (Node/Python/uv) now live in a shared machine folder (%PROGRAMDATA%): they are no longer re-downloaded on app update/reinstall and are shared across users.
  • Application data (MCPs, settings, logs) is written to the “data” folder next to the install directory; the folder no longer stays empty.

Fixes

  • The Power-Boost tool could not find installed MCPs; it now reliably detects the real data location.
  • Full uninstall now also clears the shared runtime folder, leaving no residue.

v2.0.0

Released 2026-06-26

Highlights

  • A real Windows app: the panel now opens in a single WebView2 application window instead of a browser tab.
  • Single-file install and a much smaller download (~28 MB); the backend is embedded in the app.
  • Right-click/DevTools/browser shortcuts are disabled; external links open in the system browser.
  • A single tray icon; “Quit” fully closes the app from both the window and the tray.

Fixes

  • Fixed the app not opening (a backend startup crash).
  • Close-to-tray and single-instance are now handled natively.

v1.8.1

Released 2026-06-21

Highlights

  • AI Applications: VS Code is now auto-configured with real connection detection; ChatGPT copies the public gateway URL (it does not support localhost).
  • First-Run is now an ordered, follow-the-menus setup guide.

Fixes

  • A gateway port changed in Settings/First-Run now actually applies on restart.
  • Tray restart reliably closes the old instance; two instances no longer run at once.
  • The app opens only once (single-instance hardened).
  • Home page scrolls again on small screens; Tool Calls “load more” adds +50.

v1.8

Released 2026-06-20

Highlights

  • Tray icon: the app keeps running in the background when the window is closed (Show App / Quit).
  • Live streaming for tool calls; Runtime Center; startup update check.

Fixes

  • Fixed first-install startup race and Python version incompatibility.
