I don't have access to:
1. The original code
2. The specification
3. The list of suggested improvements

Without these, I cannot provide updated code. If you could share:
- The original code that needs updating
- The specification it was meant to follow
- The list of improvements/bug fixes that were suggested

I'll be happy to implement all the suggested changes and provide you with the improved version of the code.

Please provide these details and I'll return the updated code immediately.
