 # Amnezia Web Panel
 
-A modern, high-performance web interface for managing **AmneziaWG**, **Classic WireGuard**, **Xray (XTLS-Reality)**, **Hysteria 2**, **NaiveProxy**, **Telemt (Telegram MTProxy)**, **Cloudflare WARP**, **AmneziaDNS**, **AdGuard Home**, **SOCKS5**, and **NGINX + Let's Encrypt** services on remote Ubuntu servers — from a single dashboard. Designed to provide a premium user experience with robust administrative capabilities.

     *   **NaiveProxy** (stable): HTTPS/HTTP2 camouflage proxy via [klzgrad/naiveproxy](https://github.com/klzgrad/naiveproxy) (Caddy + [klzgrad/forwardproxy](https://github.com/klzgrad/forwardproxy) naïve fork). ACME TLS on the domain, per-client basic auth, `naive+https://` share links. Requires free TCP **80** and **443**. **Use Karing** as the client — do **not** use v2rayN; other clients are untested.
     *   **Telemt (Telegram MTProxy)**: High-performance Telegram MTProxy with TLS emulation and comprehensive management (quotas, IP limits, real-time session tracking). Robust install path that auto-configures Docker's official apt/yum repository when needed.
     *   **Cloudflare WARP**: Add and manage WARP-powered connectivity from the panel for routing and network flexibility.
+    *   **NordVPN**: Connect/disconnect outbound NordVPN from Settings via the official CLI (optional country/city).
 *   **🛠 Services**:
     *   **AmneziaDNS**: Internal DNS resolver on a private docker network (`amnezia-dns-net`, IP `172.29.172.254`) to prevent DNS leaks and blockings.
     *   **AdGuard Home**: DNS-based ad blocker with a web admin UI. Two install modes: **Replace AmneziaDNS** (takes its IP, all VPN clients use AdGuard immediately) or **Side-by-side** (parallel deployment on `172.29.172.253`, web UI accessible only over the VPN by default). Optional opt-in checkboxes to expose the web UI / DoT / DoH on the host.

 ## 📋 Fix / changelog (this fork)
 
+### v2.5.2
+*   **Tunnels UI redesign** — Settings → Tunnels: grouped layout (public access / outbound VPN), provider cards, status pills, responsive grid.
+
+### v2.5.1
+*   **One-click panel update** — Settings → About → **Update panel**: downloads release ZIP from Gitea (or `git checkout` when `.git` exists), runs `pip install`, restarts.
+
+### v2.5.0
+*   **NordVPN in Tunnels** — connect/disconnect outbound NordVPN from Settings (official `nordvpn` CLI; optional country/city).
+
+### v2.4.0
+*   **Auto-update from Gitea**: Settings → About checks https://git.evilfox.cc/test2/Amnezia-Web-Panel-main releases and can install the latest tag via `git fetch` + checkout, then restart (git install only).
+
 ### v2.3.0
 *   **Cascade removed** — double-VPN feature dropped from the panel (manager, API, UI, i18n).
