 ## 📋 Fix / changelog (this fork)
 
+### v2.6.5
+*   **Mieru install fix** — wait for `/var/run/mita.sock`, seed a bootstrap user (empty `users` caused `mita start` RPC EOF), retry apply/start with systemd restart.
+
+### v2.6.4
+*   **Mieru (mita v3.28.0)** — optional per-server install from [enfein/mieru](https://github.com/enfein/mieru): native Debian/RPM package, no Docker. Marketplace + server card, TCP port at install, user connections with `mierus://` share links. Pinned release **v3.28.0** (GitHub has no v2.8.0 tag).
+
+### v2.6.3
+*   **Client connection domain (AWG / WireGuard)** — set a DNS name per server (or per AWG/WG protocol) instead of IP in client configs (`Endpoint = domain:port`). Survives server IP changes — update the A-record only. UI on server list, server page, and when adding a server.
+*   **Legacy `data.json` → PostgreSQL** — import normalizes old backups (UUIDs, duplicate usernames/tokens, string `server_info`); failed auto-import no longer bricks panel startup; JSON restore returns clear errors.
+*   **Dokploy / Traefik 404** — `traefik.http.services.amnezia_panel.loadbalancer.server.port=5000` in compose (Traefik must route to container port **5000**).
+*   **Support the project** — `/support` page for all users (SBP / card / crypto placeholders); admin configures requisites in **Settings** (no popups).
+
 ### v2.6.2
 *   **Panel backup → PostgreSQL dump** — Settings backup downloads `.sql` via `pg_dump`; restore accepts `.sql` or legacy `data.json`. JSON export kept as secondary link.
