+
+## [0.3.1] - 2025-01-27
+
+### Fixed
+- **BREAKING**: Fixed deprecated Hibernate API usage in BaseRepositoryImpl
+  - Replaced deprecated `session.createQuery()` with `session.createMutationQuery()` for DELETE operations
+  - This ensures compatibility with future Hibernate versions and removes deprecation warnings
+
+### Changed
+- Updated Hibernate ORM from 6.4.1.Final to 6.4.10.Final for better performance and security
+- Updated H2 database from 2.2.224 to 2.2.232 for latest bug fixes
+
+### Added
+- Enhanced transaction management in BaseRepositoryImpl with new helper methods:
+  - `executeInTransaction()` for operations that return values
+  - `executeInTransactionVoid()` for void operations
+  - Both methods include proper rollback handling for improved reliability
+
+### Technical Details
+- Improved error handling in repository operations
+- Better transaction safety with automatic rollback on exceptions
+- Removed FIXME comments related to deprecated API usage
+
+## [0.3.0] - 2025-01-26
+
+### Added
+- Comprehensive Spring Data JPA-like query system
+- Method name parsing for automatic query generation
+- Support for @Query, @Modifying, and @QueryHint annotations
+- Enhanced RepositoryFactory with query method support
+- Database-level query execution for improved performance
+
+### Fixed
+- Resolved "socket hang up" errors in exception handling
+- Fixed excessive logging in ORM components
+- Improved code quality and reduced duplication in repository implementations
+
+### Changed
+- Migrated from memory-based filtering to database-level queries
+- Enhanced query method parser with support for complex operations
+- Improved error messages and debugging capabilities
+
+## [0.2.0] - 2025-01-25
+
+### Added
+- Comprehensive dependency injection system
+- Spring-like annotations (@Component, @Named, @Primary, @PostConstruct, @PreDestroy)
+- Zero-configuration DI container
+- Automatic component scanning and registration
+
+### Changed
+- Enhanced framework architecture with DI support
+- Improved documentation and examples
+
+## [0.1.0] - 2025-01-24
