 # NFOGuard Development Summary
 
-## Current Status: v1.3.6 - NFO Preservation Fix
+## Current Status: v1.3.7 - NFO XML Parsing Fix
 
-### Latest Updates (v1.3.6)
-- **🔧 NFO MANAGER**: Fixed movie.nfo to preserve existing content instead of overwriting
-- **✅ PRESERVATION**: Existing movie metadata (title, plot, actors, etc.) now maintained
-- **🎯 TARGETED**: Only updates NFOGuard-managed fields (dateadded, uniqueid, lockdata)
-- **🧹 CLEANUP**: Removes old NFOGuard elements before adding new ones to avoid duplicates
+### Latest Updates (v1.3.7)
+- **� FIXED**: XML comment parsing error causing NFO creation to fail
+- **🔧 XML HANDLING**: Improved XML comment insertion and file writing
+- **✅ PRESERVATION**: Existing movie metadata properly preserved during updates
+- **🎯 ROBUST**: Better error handling for malformed XML files
 
-### NFO Management Behavior (Fixed)
-**Before (v1.3.5 and earlier):**
-```xml
-<!-- Full existing NFO with title, plot, cast, etc. -->
-↓ NFOGuard processing
-<movie>
-  <!-- Only NFOGuard fields - ALL EXISTING CONTENT LOST -->
-</movie>
+### NFO Update Process (Fixed)
+```
+1. ✅ Load existing movie.nfo (if exists)
+2. ✅ Parse and validate XML structure  
+3. ✅ Remove old NFOGuard elements to avoid duplicates
+4. ✅ Preserve all existing content (title, plot, cast, etc.)
+5. ✅ Add/update NFOGuard fields (dateadded, lockdata, uniqueid)
+6. ✅ Write properly formatted XML with comment
 ```
 
-**After (v1.3.6):**
-```xml
-<!-- Full existing NFO with title, plot, cast, etc. -->
-↓ NFOGuard processing  
-<movie>
-  <!-- NFOGuard comment and fields added -->
-  <!-- ALL EXISTING CONTENT PRESERVED -->
-  <title>Existing Title</title>
-  <plot>Existing Plot</plot>
-  <!-- ... existing content ... -->
-  <dateadded>2025-09-14T13:37:14-04:00</dateadded>
-  <lockdata>true</lockdata>
-</movie>

+### Error Resolution
+- **v1.3.6**: XML comment handling caused `'()` error
+- **v1.3.7**: Fixed comment insertion and XML serialization
+- **Result**: NFO files now update correctly while preserving contentlopment Summary
 
 ## Current Status: v1.3.3 - Database Migration & Path Validation Complete
