- Added CSRF exemption to all JWT-authenticated API endpoints
- API routes use JWT tokens, not session cookies, so CSRF protection is not needed

- Change import to from flask_wtf.csrf import csrf_exempt
- Replace @csrf.exempt with @csrf_exempt decorators

- Initialize CSRFProtect in app/__init__.py
- Update import in app/upload/routes.py from flask_wtf.csrf to flask_wtf

- Added detailed error logging with traceback for debugging
- Ensures server always returns JSON instead of HTML error pages

- Error message now shows correct maximum file size from database setting
- Consistent with other validation functions using the same setting

- validate_file_size() now uses database setting instead of MAX_CONTENT_LENGTH
- detect_malicious_content() uses database setting for size limits
- Both functions now respect the configurable max_upload_size_mb (default 2048MB = 2GB)

- Explicitly set MAX_CONTENT_LENGTH in Flask app config during initialization
- Add logging to verify MAX_CONTENT_LENGTH is set correctly
- Fixes 'File too large' error for files over 500MB (now supports 5GB)

- Add seek(), tell(), read() methods to FileLike class
- Add content_type attribute for validation
- Fixes 'FileLike object has no attribute seek' error in chunked uploads

- Fixes validation error and slow upload performance

- Add chunking JavaScript to fixture_detail.html for individual match uploads
- Add chunking JavaScript to fixture_detail.html for fixture-level bulk uploads
- Add chunking JavaScript to match_detail.html for match ZIP uploads
- All ZIP uploads now use 1MB chunks instead of uploading entire files at once
- Fixes issue where large ZIP files would fail due to memory/timeouts

- Add Migration_007_AddDoneToStatusEnum class
- Safely adds 'done' to existing status ENUM if not present
- Handles databases created before 'done' status was added

- Update README and CHANGELOG with migration details

- Updated set_active() method to require status='pending' in addition to ZIP upload completion
- Added comprehensive documentation for new active status criteria
- Updated CHANGELOG.md with version 1.2.3 details

Active status now requires:
1. ZIP upload status = 'completed'
2. ZIP checksum present
3. Match status = 'pending'

This provides more precise control over match activation workflow.

- Add status column to matches table with 8 enum values (pending, scheduled, bet, ingame, cancelled, failed, paused, done)

- Implement database migration 006 for status tracking
- Update Match model with status field and validation
- Enhance match detail template to display status information

- Fixed critical bug where both fighter1 and fighter2 were incorrectly sourced from fighter1 column during XLSX uploads
- Enhanced FixtureParser.detect_required_columns() with fighter-specific matching logic in app/upload/fixture_parser.py
- Added proper fighter number detection (1 or 2) to prevent cross-mapping during partial column matching
- Fighter1 columns now correctly map to fighter1 database field, Fighter2 to fighter2 field
- Prevents false positives where 'fighter2' column incorrectly matched 'fighter1' field
- Root cause: Original partial matching used split()[0] causing both 'fighter 1' and 'fighter 2' to become 'fighter'
- Solution: Implemented specific logic checking for both 'fighter' keyword AND number in column names
- Updated documentation (README.md, CHANGELOG.md) with bug fix details and version bump to v1.2.2
- Maintains backward compatibility with existing column naming conventions

- Fixed import error for get_persistent_directories (renamed to get_config_directory)
- Fixed TypeError with classmethod call during class definition
- Added config directory support to directory utilities
- Enhanced configuration loading with proper function structure
- Ensured all persistent directories are created during setup

## Cross-Platform PyInstaller Support
- Implemented persistent directory system for Windows (%APPDATA%), macOS (~/Library/Application Support), and Linux (/opt/MBetter)
- Added PyInstaller environment detection and automatic directory path optimization
- Created comprehensive directory utilities (app/utils/directories.py) with fallback mechanisms
- Enhanced configuration system to use persistent mbetterd.conf instead of .env for PyInstaller deployments

## Configuration System Enhancement
- Added configuration file migration system (migrate_config.py) for .env to mbetterd.conf transition
- Enhanced config.py with persistent config file loading and priority system (env vars > config file > defaults)
- Automatic config file discovery in persistent directories with fallback to local .env

## Authenticated ZIP Downloads
- Added new /api/download/zip/<match_id> endpoint with hybrid JWT/API token authentication
- Enhanced /api/updates endpoint to use authenticated download URLs instead of web routes
- Implemented access control ensuring users can only download their own match files (or admin access)
- Updated API routes to use persistent ZIP_UPLOADS_DIR for file serving

## Upload System Enhancement
- Modified file upload handlers to use persistent directories (ZIP_UPLOADS_DIR, FIXTURES_DIR, TEMP_DIR)
- Enhanced upload file paths to use appropriate persistent directories based on file type
- Updated main routes for ZIP downloads to use persistent directory paths
- Fixed PyInstaller temporary directory issues ensuring files persist between application restarts

## Documentation Updates
- Updated README.md with PyInstaller features, cross-platform compatibility, and authenticated downloads
- Enhanced CHANGELOG.md with comprehensive v1.2.1 release notes
- Added migration utility documentation and deployment instructions
- Updated version numbers and platform compatibility information

## Technical Improvements
- Enhanced error handling and logging throughout persistent directory operations
- Added comprehensive fallback mechanisms for various deployment scenarios
- Improved path handling with proper cross-platform directory structures
- Security enhancements for API file downloads with proper authentication validation

## New Features
- **New /api/updates endpoint**: Incremental fixture synchronization with optional timestamp filtering
  - Supports both GET (query params) and POST (JSON body) methods
  - Optional 'from' parameter for unix timestamp-based filtering
  - Returns fixtures updated after specified timestamp or last N fixtures
  - Includes ZIP download URLs in API response
  - Configurable default count via system settings

- **Fixture active time tracking**: Automatic timestamp management
  - Added fixture_active_time column (BigInteger, indexed) to matches table
  - Automatic timestamp setting when all matches in fixture become active
  - Preserves original activation time (no overwrites)

- **Hybrid authentication system**: Maximum compatibility
  - Supports JWT tokens (short-lived, from login) AND API tokens (long-lived, from web interface)
  - Tries JWT first, falls back to API tokens automatically
  - Multiple token header formats: Authorization Bearer, X-API-Token, query parameter

- **SHA1-based ZIP file naming**: Consistent file naming
  - Uses SHA1 hash of (unix_timestamp + original_filename)
  - Applied across all upload methods for consistency

## Technical Implementation
- **Database Migration_005**: Added fixture_active_time column with proper indexing
- **System settings integration**: New api_updates_default_count setting (default: 10)
- **Backfill utility**: backfill_fixture_times.py for existing fixture data migration
- **Fallback mechanisms**: Graceful degradation for existing data without timestamps
- **Query optimization**: Proper limits and ordering for both default and filtered queries

## Bug Fixes
