15+ improvements and new features come to prototyping

I apologize, but the content provided appears to be primarily navigation menus, headers, footers, and page chrome from the Figma website. The actual release notes content for "15+ improvements and new features come to prototyping" is not included in the extracted HTML you've provided.

The page shows:

• Navigation menus (Products, Solutions, Community, Resources)
• A "Release Notes" section header
• A message stating "Sorry, there are no results that include all these filters"
• Footer links and language options

To extract the actual release notes, I would need the main content section that contains the specific details about the 15+ improvements and new prototyping features. Could you provide the full page content including the main release notes section?
