+## 🔧 Recent Bug Fixes & Improvements (v3.4.5)
+### **Unified Download Workflow Architecture**
+- **Unified execution pipeline**: All download modes now use the same execution workflow, eliminating inconsistencies and broken pipelines
+- **Consistent behavior**: All modes (--channel-focus, --all-videos, --songlist-only, --latest-per-channel) use identical download execution, progress tracking, and error handling
+- **Centralized download logic**: Single `execute_unified_download_workflow()` method handles all download execution
+- **Automatic parallel support**: All download modes automatically support `--parallel --workers N` without additional implementation
+- **Unified cache management**: Consistent progress tracking and resume functionality across all modes
+
+### **Architecture Pattern for New Download Modes**
+When adding new download modes in the future, follow this pattern to ensure consistency:
+
+#### **1. Download Plan Building (Mode-Specific)**
+Each download mode should build a download plan (list of videos to download) with this structure:
+```python
+download_plan = [
+    {
+        "video_id": "video_id",
+        "artist": "artist_name", 
+        "title": "song_title",
+        "filename": "sanitized_filename.mp4",
+        "channel_name": "channel_name",
+        "video_title": "original_video_title",
+        "force_download": False
+    }
+]
+```
+
+#### **2. Unified Execution (Shared)**
+All modes should use the unified execution workflow:
+```python
+downloaded_count, success = self.execute_unified_download_workflow(
+    download_plan=download_plan,
+    cache_file=cache_file,  # Optional, for progress tracking
+    limit=limit,            # Optional, for limiting downloads
+    show_progress=True,     # Optional, for progress display
+)
+```
+
+#### **3. Execution Method Selection (Automatic)**
+The unified workflow automatically chooses execution method based on settings:
+- **Sequential**: Uses `DownloadPipeline` for single-threaded downloads
+- **Parallel**: Uses `ParallelDownloader` when `--parallel` is enabled
+
+#### **4. Required Implementation Pattern**
+```python
+def download_new_mode(self, ...):
+    """New download mode implementation."""
+    
+    # 1. Build download plan (mode-specific logic)
+    download_plan = []
+    for video in videos_to_download:
+        download_plan.append({
+            "video_id": video["id"],
+            "artist": artist,
+            "title": title,
+            "filename": filename,
+            "channel_name": channel_name,
+            "video_title": video["title"],
+            "force_download": force_download
+        })
+    
+    # 2. Create cache file (optional, for progress tracking)
+    cache_file = get_download_plan_cache_file("new_mode", **plan_kwargs)
+    save_plan_cache(cache_file, download_plan, [])
+    
+    # 3. Use unified execution workflow
+    downloaded_count, success = self.execute_unified_download_workflow(
+        download_plan=download_plan,
+        cache_file=cache_file,
+        limit=limit,
+        show_progress=True,
+    )
+    
+    return success
+```
+
+### **Benefits of Unified Architecture**
+- **Consistency**: All modes behave identically for execution, progress tracking, and error handling
+- **Maintainability**: Changes to download execution only need to be made in one place
+- **Reliability**: Eliminates broken pipelines and inconsistent behavior between modes
+- **Extensibility**: New modes automatically get all existing features (parallel downloads, progress tracking, etc.)
+- **Testing**: Easier to test since all modes use the same execution logic
+
+### **What Was Fixed**
+- **Broken Pipeline**: Previously, different modes used different execution paths, leading to inconsistencies
+- **Missing Method**: Added missing `download_latest_per_channel()` method that was referenced in CLI but not implemented
+- **Code Duplication**: Eliminated duplicate download execution logic across different modes
+- **Inconsistent Behavior**: All modes now have identical progress tracking, error handling, and cache management
+
+### **Future Development Guidelines**
+1. **NEVER implement custom download execution logic** in new download modes
+2. **ALWAYS use `execute_unified_download_workflow()`** for download execution
+3. **Focus on download plan building** - that's where mode-specific logic belongs
+4. **Use the standard download plan structure** for consistency
+5. **Implement cache file handling** for progress tracking and resume functionality
+6. **Test with both sequential and parallel modes** to ensure compatibility

+## 🔧 Development Guidelines
+
+### **Adding New Download Modes**
+When adding new download modes, follow the unified workflow pattern to ensure consistency:
+
+#### **1. Build Download Plan (Mode-Specific)**
+```python
+def download_new_mode(self, ...):
+    # Build download plan with standard structure
+    download_plan = []
+    for video in videos_to_download:
+        download_plan.append({
+            "video_id": video["id"],
+            "artist": artist,
+            "title": title,
+            "filename": filename,
+            "channel_name": channel_name,
+            "video_title": video["title"],
+            "force_download": force_download
+        })

+#### **2. Key Principles**
+- **NEVER implement custom download execution logic** - always use `execute_unified_download_workflow()`
+- **Focus on download plan building** - that's where mode-specific logic belongs
+- **Use the standard download plan structure** for consistency
+- **Implement cache file handling** for progress tracking and resume functionality

+- **Improved title parsing**: Enhanced `extract_artist_title` function to handle multiple video title formats

+- **Better matching accuracy**: Can now parse titles like "Hold On Loosely Karaoke | 38 Special Karaoke Version"
-  - `"Title Artist KARAOKE"` → Attempts to extract artist from complex titles
+- **Consistent parsing**: All modules now use the same parsing logic from `fuzzy_matcher.py`
-  - `"Artist - Title"` → Standard format (unchanged)
+- **Reduced false negatives**: Songs that previously couldn't be matched due to title format differences now have a higher chance of being found
-- **Consolidated parsing logic**: All modules now use the same `extract_artist_title` function from `fuzzy_matcher.py`
+
-- **Better matching accuracy**: Reduced false negatives for songs with non-standard title formats
+### **Fixed Import Conflicts**

+- **Consistent behavior**: All parts of the system use the same parsing logic
+- **Cleaner codebase**: Eliminated duplicate code and import conflicts
