 # Changelog
 
-## [0.9.10] - 2025-01-23
+## [0.9.10] - 2025-08-23
+
+### 🐛 Fixed
+- **Исправлена ошибка инициализации MuVERA**: Устранена ошибка `module 'muvera' has no attribute 'Client'`
+- **Создан MuveraWrapper**: Реализован простой wrapper вокруг `muvera.encode_fde` для обеспечения ожидаемого интерфейса
+- **Добавлена зависимость numpy**: Установлен numpy>=1.24.0 для векторных операций в поисковом сервисе
+
+### 🏗️ Changed
+- **Рефакторинг SearchService**: Заменен несуществующий `muvera.Client` на `MuveraWrapper`
+- **Упрощена архитектура поиска**: Поисковый сервис теперь использует доступную функциональность FDE кодирования
+- **Обновлен requirements.txt**: Добавлен numpy для поддержки векторных вычислений
+
+### 📦 Added
+- **MuveraWrapper класс**: Простая обертка для `muvera.encode_fde` с базовой функциональностью поиска
+- **Поддержка FDE кодирования**: Интеграция с MuVERA для кодирования многомерных векторов в фиксированные размерности
+- **Базовая функциональность поиска**: Простая реализация поиска по косинусному сходству
+
+### 🧪 Tests
+- **Проверена инициализация**: SearchService успешно создается и инициализируется
+- **Проверен базовый поиск**: Метод search() работает корректно (возвращает пустой список для пустого индекса)
 
 ### 🐛 Fixed
 - **Исправлена критическая ошибка с уведомлениями**: Устранена ошибка `null value in column "kind" of relation "notification" violates not-null constraint`
