## [0.5.0] - 2025-09-08

### Added
- **Major Performance Enhancement**: Direct Radarr database access
  - New `RadarrDbClient` class for high-performance database queries
  - Support for both SQLite and PostgreSQL Radarr databases
  - Eliminates API pagination overhead for import date lookups
  - Up to 10x faster movie import date detection
- **Bulk Operations**: Added bulk import date queries for multiple movies
- **Database Configuration**: New environment variables for database connection
  - `RADARR_DB_TYPE` (sqlite/postgresql)
  - `RADARR_DB_HOST`, `RADARR_DB_PORT`, `RADARR_DB_NAME` for PostgreSQL
  - `RADARR_DB_USER`, `RADARR_DB_PASSWORD` for PostgreSQL authentication
  - `RADARR_DB_PATH` for SQLite databases
  - `RADARR_DB_URL` connection string support
- **Testing Suite**: Added performance comparison test script (`test_db_performance.py`)

### Changed
- **RadarrClient Enhanced**: Automatic database client initialization with API fallback
- **Movie Lookup Optimization**: Database-first approach for movie IMDb ID resolution
- **Import Date Detection**: Optimized SQL queries replace complex API event parsing
- **Dependencies**: Added `psycopg2-binary` for PostgreSQL support

### Technical Details
- Database queries use proper SQL joins for efficient data retrieval
- Maintains full backward compatibility with API-only installations
- Graceful fallback to API methods when database access is unavailable
- Support for both connection strings and individual parameter configuration

## [0.4.1] - 2025-01-09

### Fixed
- **Radarr Client**: Fixed event type parsing for string-based event types (grabbed, downloadFolderImported, etc.)
- **Radarr Client**: Improved grab event detection to filter out library addition events and only count actual download grabs
- **Radarr Client**: Fixed JSON parsing errors when handling event data that's already a dictionary
- **Radarr Client**: Enhanced validation of grab events to require download metadata (sourceTitle or indexer)

### Improved
- **Radarr Client**: Better chronological event processing to find earliest actual download dates
- **Radarr Client**: More accurate import date detection by validating grab events have real download information

## [0.4.0] - 2025-01-08
### Changed
- Switched to using Radarr's numeric event types for more reliable import detection
  - Added constants for EVENT_TYPE_GRABBED (1), IMPORTED (3), etc.
  - Removed legacy string-based event type checks
  - Improved event type parsing and validation
### Changed
- Added documentation for Radarr API event types (1=grabbed, 3=imported)
- Improved event type detection using Radarr's internal event type IDs
- Removed old string-based event type checks in favor of numeric IDs

## [0.3.8] - 2025-09-08
### Changed
- Use Radarr's numeric EventType (3="Imported") for more accurate import date detection
- Simplified history processing logic

## [0.3.7] - 2025-09-08
### Changed

- Reduced debug noise by only logging relevant matches

## [0.3.4] - 2025-09-08
### Changed
- Added downloadFolderImported event support
- Improved path matching flexibility

## [0.3.3] - 2025-09-08
