| Feature | What Changed | Benefit |
|---------|--------------|---------|
| Node 20 & Chromium 119 compatibility | Updated native bindings to support the latest Node LTS and Chrome/Edge/WebView2 releases. | No more “WebSocket not supported” errors on up‑to‑date browsers. |
| Signed certificates by default | The installer now generates a self‑signed certificate and automatically adds it to the OS trust store (Windows Store, macOS Keychain, Linux NSS). | Eliminates the manual “untrusted connection” warnings that plagued earlier versions. |
| Improved USB‑HID handling | Refactored USB driver layer; added support for HID‑POS devices (e.g., magnetic stripe readers). | Seamless integration with new hardware without custom drivers. |
| Reduced memory footprint | Core runtime shrunk from ~12 MB to ~7 MB on idle. | Faster start‑up on low‑powered devices (Raspberry Pi, embedded Windows). |
| Enhanced logging & diagnostics | New “Diagnostics Dashboard” (accessible via http://localhost:8150/diagnostics). | One‑click access to system logs, printer status, and JavaScript error traces. |
| Built‑in auto‑updater | Optional background updater that checks the official feed once per day. | Keeps installations current without manual re‑download. |
| License‑compliant packaging | All third‑party binaries now ship with proper OSS notices. | Easier compliance for enterprise deployments. | qz tray 19 8 top download
