 - Added seed parameter to both TTS and VC nodes for reproducible generation
 - Seed range: 0 to 4,294,967,295 (32-bit integer)
 - Enables consistent audio output for debugging and workflow control
+- Made Perth watermarking optional to fix Python 3.12+ compatibility issues
+- Nodes now function without watermarking if resemble-perth import fails
 
 ### 5/31/2025
 - Added Persistent model loading, and loading bar functionality
