+## Релиз v1.4
+
+**Лимиты групп пользователей**
+
+- В `/admin/groups` администратор задаёт для каждой группы:
+  - **Квота диска** (МБ, `0` = без лимита)
+  - **Максимум папок** на пользователя (`0` = без лимита)
+  - **Максимум фото** на пользователя (`0` = без лимита)
+- Лимиты проверяются при создании папки и загрузке фото
+- В личном кабинете отображается использование квот
+
+**Переменные `.env` для группы по умолчанию:**
+
+```env
+DEFAULT_GROUP_QUOTA_MB=100
+DEFAULT_GROUP_MAX_FOLDERS=10
+DEFAULT_GROUP_MAX_PHOTOS=500
+```
+
+**Рекламные баннеры**
+
+- Управление в `/admin/banners`
+- Позиции: главная (под hero), личный кабинет, подвал
+- URL изображения, опциональная ссылка при клике, порядок сортировки, вкл/выкл
+
+**Обновление до v1.4 на сервере:**
+
+```bash
+cd ~/fotohost
+git fetch --tags
+git checkout v1.4
+docker compose up -d --build
