@@ -5,6 +5,90 @@ All notable changes to this project will be documented in this file.

 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 
+## [Unreleased]
+
+### Added
+
+- **Custom Output Templates**: Flexible filename customization system
+  - New `output_template` configuration in unshackle.yaml for movies, series, and songs
+  - Support for conditional variables using `?` suffix (e.g., `{year?}`, `{hdr?}`)
+  - Comprehensive template variables for title, quality, audio, video, and metadata
+  - Multiple naming styles: Scene-style (dot-separated), Plex-friendly (space-separated), minimal, custom
+  - Automatic template validation and enhanced error handling
+  - **Full backward compatibility**: Old `scene_naming` option still works and automatically converts to equivalent templates
+  - Folder naming now follows series template patterns (excluding episode-specific variables)
+  - Deprecation warnings guide users to migrate from `scene_naming` to `output_template`
+
+### Changed
+
+- **Filename Generation**: Updated all title classes (Movie, Episode, Song) to use new template system
+  - Enhanced context building for template variable substitution
+  - Improved separator handling based on template style detection
+  - Better handling of conditional content like HDR, Atmos, and multi-language audio
+
+## [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
+
+- Deprecated version references in application banner for clarity
+
+## [1.4.3] - 2025-08-20
+
+### Added
+
+- Cached IP info helper for region detection
+  - New `get_cached_ip_info()` with 24h cache and provider rotation (ipinfo/ipapi) with 429 handling.
+  - Reduces external calls and stabilizes non-proxy region lookups for caching/logging.
+
+### Changed
+
+- DRM decryption selection is fully configuration-driven
+  - Widevine and PlayReady now select the decrypter based solely on `decryption` in YAML (including per-service mapping).
+  - Shaka Packager remains the default decrypter when not specified.
+  - `dl.py` logs the chosen tool based on the resolved configuration.
+- Geofencing and proxy verification improvements
+  - Safer geofence checks with error handling and clearer logs.
+  - Always verify proxy exit region via live IP lookup; fallback to proxy parsing on failure.
+- Example config updated to default to Shaka
+  - `unshackle.yaml`/example now sets `decryption.default: shaka` (service overrides still supported).
+
+### Removed
+
+- Deprecated parameter `use_mp4decrypt`
+  - Removed from `Widevine.decrypt()` and `PlayReady.decrypt()` and all callsites.
+  - Internal naming switched from mp4decrypt-specific flags to generic `decrypter` selection.
+

+
+    This class provides a drop-in replacement for pywidevine's local CDM using
+    Decrypt Labs' KeyXtractor API service, enhanced with smart caching logic
+    that minimizes unnecessary license requests.
+
+    Key Features:
+    - Compatible with both Widevine and PlayReady DRM schemes
+    - Intelligent caching that compares required vs. available keys
+    - Automatic key combination for mixed cache/license scenarios
+    - Seamless fallback to license requests when keys are missing
+
+    Intelligent Caching System:
+    1. DRM classes (PlayReady/Widevine) provide required KIDs via set_required_kids()
+    2. get_license_challenge() first checks for cached keys
+    3. If cached keys satisfy requirements, returns empty challenge (no license needed)
+    4. If keys are missing, makes targeted license request for remaining keys
+    5. parse_license() combines cached and license keys intelligently
