 ## 📋 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).
