+## [1.4.5] - 2025-09-09
+
+### Added
+
+- **Enhanced CDM Key Caching**: Improved key caching and session management for L1/L2 devices
+  - Optimized `get_cached_keys_if_exists` functionality for better performance with L1/L2 devices
+  - Enhanced cached key retrieval logic with improved session handling
+- **Widevine Common Certificate Fallback**: Added fallback to Widevine common certificate for L1 devices
+  - Improved compatibility for L1 devices when service certificates are unavailable
+- **Enhanced Vault Loading**: Improved vault loading and key copying logic
+  - Better error handling and key management in vault operations
+- **PSSH Display Optimization**: Truncated PSSH string display in non-debug mode for cleaner output
+- **CDM Error Messaging**: Added error messages for missing service certificates in CDM sessions
+
+### Changed
+
+- **Dynamic Version Headers**: Updated User-Agent headers to use dynamic version strings
+  - DecryptLabsRemoteCDM now uses dynamic version import instead of hardcoded version
+- **Intelligent CDM Caching**: Implemented intelligent caching system for CDM license requests
+  - Enhanced caching logic reduces redundant license requests and improves performance
+- **Enhanced Tag Handling**: Improved tag handling for TV shows and movies from Simkl data
+  - Better metadata processing and formatting for improved media tagging
+
+### Fixed
+
+- **CDM Session Management**: Clean up session data when retrieving cached keys
+  - Remove decrypt_labs_session_id and challenge from session when cached keys exist but there are missing kids
+  - Ensures clean state for subsequent requests and prevents session conflicts
+- **Tag Formatting**: Fixed formatting issues in tag processing
+- **Import Order**: Fixed import order issues in tags module
+
+## [1.4.4] - 2025-09-02
+
+### Added
+
+- **Enhanced DecryptLabs CDM Support**: Comprehensive remote CDM functionality
+  - Full support for Widevine, PlayReady, and ChromeCDM through DecryptLabsRemoteCDM
+  - Enhanced session management and caching support for remote WV/PR operations
+  - Support for cached keys and improved license handling
+  - New CDM configurations for Chrome and PlayReady devices with updated User-Agent and service certificate
+- **Advanced Configuration Options**: New device and language preferences
+  - Added configuration options for device certificate status list
+  - Enhanced language preference settings
+
+### Changed
+
+- **DRM Decryption Enhancements**: Streamlined decryption process
+  - Simplified decrypt method by removing unused parameter and streamlined logic
+  - Improved DecryptLabs CDM configurations with better device support
+
+### Fixed
+
+- **Matroska Tag Compliance**: Enhanced media container compatibility  
+  - Fixed Matroska tag compliance with official specification
+- **Application Branding**: Cleaned up version display
+  - Removed old devine version reference from banner to avoid developer confusion
+  - Updated branding while maintaining original GNU license compliance
+- **IP Information Handling**: Improved geolocation services
+  - Enhanced get_ip_info functionality with better failover handling
+  - Added support for 429 error handling and multiple API provider fallback
+  - Implemented cached IP info retrieval with fallback tester to avoid rate limiting
+- **Dependencies**: Streamlined package requirements
+  - Removed unnecessary data extra requirement from langcodes
+
+### Removed
