# Changelog

All notable changes to this project will be documented in this file.

## [Unreleased] - v0.6.0

### Added
- **🔐 Secure Configuration System**: Two-file configuration with automatic API key masking
  - **Main `.env`**: Paths and preferences (safe to share for debugging)
  - **Separate `.env.secrets`**: API keys and passwords (never committed to git)
  - **Automatic Loading**: Both files loaded at startup with python-dotenv
  - **Log Security**: API keys automatically masked in all log output
  - **Git Protection**: Updated .gitignore prevents accidental commits of sensitive data
- **🧠 Smart Date Validation**: Intelligent release date selection with configurable gap detection
  - **Automatic Detection**: Prefers theatrical dates when digital/physical are unreasonably late
  - **Configurable**: `MAX_RELEASE_DATE_GAP_YEARS=10` (default: 10 years maximum gap)
  - **Example**: "The Craft (1996)" prefers 1996 theatrical over 2022 physical release
  - **Toggle**: `ENABLE_SMART_DATE_VALIDATION=true` to enable/disable feature
- **🧹 Repository Cleanup**: Removed legacy and duplicate files
  - **Removed**: `media_date_cache.py`, `webhook_server.py` (replaced by nfoguard.py)
  - **Removed**: Outdated documentation files (`API_ENDPOINTS.md`, `MIGRATION.md`, `STRUCTURE.md`)
  - **Streamlined**: Cleaner codebase with only essential files
- **🎯 Configurable Release Date Priority System**: Revolutionary smart fallback for manual imports
  - **Configurable Priority Order**: `RELEASE_DATE_PRIORITY=digital,physical,theatrical` (customizable)
  - **Digital Releases**: VOD/streaming dates (Netflix, iTunes, etc.) - TMDB type 4
  - **Physical Releases**: DVD/Blu-ray dates - TMDB type 5  
  - **Theatrical Releases**: Cinema release dates - TMDB type 3
  - **Smart Comparison Logic**: Prevents unrealistic dates (won't use 2000 digital for 1983 movie)
  - **Per-Movie Intelligence**: "The Craft (1996)" gets 1996 theatrical, "Top Gun Maverick (2022)" gets digital
  - **Configuration**: `PREFER_RELEASE_DATES_OVER_FILE_DATES=true` replaces old digital-only setting
- **🔇 File Date Fallback Control**: New option to completely disable file date usage
  - **Configuration**: `ALLOW_FILE_DATE_FALLBACK=false` (default: false)
  - **Behavior**: Movies with no release dates get skipped instead of using file dates
  - **Clean Logs**: Eliminates "Using file dateAdded as fallback" warnings
- **Enhanced Debug Endpoints**:
  - `/debug/movie/{imdb_id}/priority` - Shows date selection logic and available sources
  - Detailed analysis of file date vs digital date decisions
- **Complete API Documentation**: Updated README with all curl commands and response examples
- **Testing Infrastructure**: 
  - `test_bulk_update.py` - Database connection validation
  - `test_movie_scan.py` - Directory scanning logic testing  
  - `test_end_to_end.py` - Complete workflow validation
- **External API Integration**:
  - TMDB API for digital release dates
  - OMDb API for DVD/digital release dates
  - Jellyseerr integration for additional digital release data
- **Deployment Documentation**:
  - `SETUP.md` - Secure configuration setup guide
  - `DEPLOYMENT.md` - Complete Docker deployment guide  
  - `TESTING.md` - Testing strategy and troubleshooting
  - `.env.template` - Clean main configuration template
  - `.env.secrets.template` - Secure secrets configuration template
  - `docker-compose.yml` - Production-ready deployment with volume mounts

### Changed
- **Configuration Management**: Secure two-file system replaces single .env approach
  - **Separated Concerns**: Main config (.env) vs sensitive data (.env.secrets)
  - **Enhanced Security**: API key masking and git protection built-in
  - **Docker Integration**: Updated docker-compose.yml with proper volume mounts
- **Movie Priority Logic**: Enhanced `import_then_digital` to intelligently handle file date fallbacks
- **README.md**: Complete rewrite with secure configuration examples and curl commands

### Fixed
- **Manual Import Handling**: Movies manually imported to Radarr now use digital release dates instead of file modification dates
- **Path Configuration**: Fixed hardcoded media paths, now fully configurable via environment variables
- **Debug History Endpoint**: Fixed endpoint showing wrong movie events (still needs database-only implementation)

### Technical Details
- Maintains full backward compatibility with existing configurations
- Smart date comparison algorithm considers theatrical release dates when available
- Environment variable validation and fallback to sensible defaults

- Completely eliminated Radarr API usage for movie lookups and import date detection
- All movie operations now use direct database queries exclusively
- Debug endpoints updated to use database-only methods
- Enhanced error messaging when database access is not configured

### Fixed
- Fixed debug endpoint still calling API methods despite database availability
