     *   **AmneziaWG (AWG / AWG 2.0 / AWG Legacy)**: Advanced WireGuard-based protocol with S3/S4 obfuscation to bypass deep packet inspection (DPI). Three coexisting variants — modern AWG 2.0 with full junk-packet masking, and a legacy variant for older clients.
     *   **Classic WireGuard**: Standard, high-performance WireGuard protocol for unmatched speed and broad device compatibility with traffic monitoring support.
     *   **Xray (XTLS-Reality)**: Stealthy protocol that masks VPN traffic as standard HTTPS browsing. Pinned to **Xray-core v26.x**; transparently reads both the **panel layout** (`meta.json` + `clientsTable.json`) and the **native Amnezia client layout** (`xray_*.key` files + `clientsTable`), so a node first installed via the official mobile/desktop app can be attached to the panel without re-installation.
+    *   **Hysteria 2**: QUIC/HTTP3 proxy from [apernet/hysteria](https://github.com/apernet/hysteria) via `tobyxdd/hysteria:v2` — Let's Encrypt TLS, salamander obfuscation, password auth, `hy2://` share links. Per-server SSL domain/email defaults, renew from settings; install requires free TCP **80** and **443**.
+    *   **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).
+
+### v2.2.1
+*   **Cascade egress verify fix**: bind curl to ENTRY `awg0`/`wg0` IP (client-subnet policy route), not cascade peer Address.
+*   Soft-warn (no rollback) when policy route via `cascade` is OK but public-IP echo services fail.
+
+### v2.2.0
+*   **Cascade (double VPN) restored** — later removed in **v2.3.0**.
+*   Inspired by [ryderams/amneziawg-cascade](https://github.com/ryderams/amneziawg-cascade); logic ran over panel SSH (**no remote curl|bash**).
+
+### v2.1.0
+*   **NaiveProxy — stable**: production-ready install (Caddy + klzgrad/forwardproxy), share links always include `:443`.
+*   **Client notes (important)**:
+    *   **Do not use v2rayN** with NaiveProxy (broken DNS/IPv6 behaviour → latency −1 ms even when the server is fine).
+    *   **Karing** — confirmed working.
+    *   Other clients — untested / use at your own risk.
+*   Share-link and config UI hints updated accordingly.
+
+### v2.0.0-beta
+*   **NaiveProxy** (Beta): install [klzgrad/naiveproxy](https://github.com/klzgrad/naiveproxy) server via Caddy + naïve [forwardproxy](https://github.com/klzgrad/forwardproxy) — domain TLS (ACME), per-client basic auth, `naive+https://` share links.
+*   Marketplace / server page / users / invites / Telegram / backups include NaiveProxy.
+*   Install warns that free TCP **80** and **443** are required; uses per-server SSL domain/email defaults when set.
+*   Official prebuilt Caddy on amd64; xcaddy build path for other arches.
+*   Version line bumped to **2.0 Beta** (`v2.0.0-beta`).
+
+### v1.8.0
+*   **Hysteria 2** fully wired in marketplace, server page, users/invites, Telegram bot, and backups.
+*   **Per-server SSL defaults**: set domain + Let's Encrypt email when adding/editing a server; values pre-fill Hysteria (and NGINX) install forms.
+*   **SSL renew**: change domain or use “Renew SSL” in Hysteria settings to re-issue the certificate (needs free TCP 80).
+*   **Install warning**: free TCP ports **80** and **443** required for stable Let's Encrypt / HTTPS-QUIC operation.
+*   Official image `tobyxdd/hysteria:v2`, salamander obfs, password auth, `hy2://` share links, selectable UDP listen port.
+
+### v1.7.0
+*   **Clearer create flow**: pick **server first**, then **protocol** (WireGuard, AmneziaWG 2.0, …) — invites, guest access, and user connections no longer dump everything into one messy list.
+*   Protocol titles are human-readable and ordered (AWG 2.0 → AWG → Legacy → WireGuard → Xray → Telemt → Hysteria).
+*   3x-ui is a separate “server” choice; VLESS inbounds still load from that panel’s API.
+*   **Hysteria 2** manager restored ([apernet/hysteria](https://github.com/apernet/hysteria)) — see **v1.8.0** for full panel integration.
+
 ### v1.6.0
 *   **3x-ui multi-panel**: register several 3x-ui servers in Settings; pick a panel and load VLESS inbounds over its API when creating users/invites (share link comes from 3x-ui).
 *   **Docker / CI**: refreshed `Dockerfile` + compose, `.env.example`, CI checks, GHCR image workflow.
-*   **Cascade removed** for now (pending redesign — showed active while internet often did not work).
+*   **Cascade** was temporarily removed in this release (briefly restored in v2.2.x, removed again in **v2.3.0**).
 *   **WG/AWG backups**: ZIP export of client `.conf` + restore with loading feedback.
 *   **API performance**: in-memory data cache, faster server check/stats.
 *   **Share / guest**: one-tap “Copy key”.
 *   **User expiration**: countdown can start on first config use; UTC-safe comparisons.
 *   **UI**: shared SVG icon system.
-*   **Removed earlier**: Hysteria 2.
