+## 1.4.8 — сторож роутера не трогает чужие туннели
+- Исправлено: если сторож не находил интерфейс Phobos (удалён или переименован), он брал Wireguard3 по умолчанию и прописывал туда пир Phobos — ломался посторонний WireGuard-туннель. Теперь он просто пропускает проверку.
+- Роутерам: обновить скрипты из панели или переустановить клиента; серверу — `phobos-update stable`.
+
+## 1.4.7 — роутеры Keenetic сами переключаются между серверами
+- Исправлено: после переключения на другой сервер туннель на роутере переставал работать — пир прописывался на порт обфускатора 13255, а он мог слушать другой. Порт теперь берётся из `wg-obfuscator.conf`.
+- Исправлено: проверка и обновление конфига по расписанию на Keenetic не запускались — задачи писались в `/opt/etc/crontab`, который демон не читает. Теперь busybox `crond` и crontab пользователя root.
+- Исправлено: `phobos-pull` навсегда зависал на `wget`, если туннель не работает (таймаут 8 с).
+- Роутерам: переустановить клиента или обновить скрипты из панели; серверу — `phobos-update stable`.
+
+## 1.4.6 — роутеры снова получают смену адреса
+- Исправлено: роутер получал 403 при pull конфига, если клиент создан через API/бота (`/api/client/ensure`) — смена адреса/сервера до него не доходила. Теперь принимается и общий ключ из пакета, и личный токен клиента. Роутеры переустанавливать не нужно — достаточно обновить панель.
+
 ## 1.4.5 — подсеть при установке, beta/dev по токену
 
 - **feat:** beta и dev теперь берутся из приватного репозитория на Gitea (GitHub заблокирован): `phobos-update beta|dev` с токеном подписчика — в панели «Настройки → Версия и обновления → токен подписчика» или `GH_TOKEN=… phobos-update beta`. Без токена updater сообщает, что канал закрыт, и ничего не трогает.
