+## 🔧 Recent Bug Fixes & Improvements (v3.4.7)
+### **Configurable Data Directory Path**
+- **Centralized Data Path Management**: New `data_path_manager.py` module provides unified data directory path management
+- **Configurable Location**: Data directory path can be set in `config/config.json` under `folder_structure.data_dir`
+- **Backward Compatibility**: Defaults to "data" directory if not configured
+- **Cross-Project Integration**: Enables the karaoke downloader to be used as a component in other projects with different data directory structures
+- **Updated All Modules**: All modules now use the data path manager instead of hardcoded "data/" paths
+- **Utility Functions**: Provides `get_data_path()`, `get_data_dir()`, and `get_data_path_manager()` functions for easy access
+- **Fixed Circular Dependency**: Moved `config.json` from `data/` to root directory to resolve chicken-and-egg problem
+
+### **Benefits of Configurable Data Directory**
+- **Flexible Deployment**: Can be integrated into other projects with different directory structures
+- **Centralized Configuration**: Single point of configuration for all data file paths
+- **Maintainable Code**: Eliminates hardcoded paths throughout the codebase
+- **Easy Testing**: Can use temporary directories for testing without affecting production data
+- **Future-Proof**: Makes it easier to change data directory structure in the future
+
+### **Circular Dependency Solution**
+The original implementation had a circular dependency problem:
+- **Problem**: `config.json` was located in the `data/` directory
+- **Issue**: To read the config file, we needed to know where the data directory is
+- **Conflict**: But the data directory location is specified in the config file
+- **Solution**: Moved `config.json` to the `config/` directory as a fixed location
+- **Result**: Config file is always accessible in a dedicated config directory, and data directory can be configured within it
+- **Backward Compatibility**: System still works with config files in custom data directories when explicitly specified
+
