 ## 📂 Техническая информация
 
+### Последние обновления
+- Массовые операции VK (`remove/add/admin`) выполняются в фоновом потоке, чтобы интерфейс не зависал; добавлен визуальный прогресс-бар.
+- Распаковка архива автообновления теперь валидирует пути перед извлечением для защиты от path traversal.
+- Проверка обновлений переведена на `QThread` (модель потоков Qt) вместо Python `threading.Thread`.
+- В Windows сохранение токена требует успешного шифрования через DPAPI; при ошибке шифрования сессия продолжается, но токен не сохраняется на диск.

 ### Сборка проекта (для разработчиков)
 Проект использует кастомный скрипт автоматизации `build.py`, который оптимизирует зависимости `PySide6` и корректно упаковывает `QtWebEngineCore`.
