v1.31.5-beta.1

Percy now fully supports asynchronous DOM serialization, enabling accurate snapshots of modern web applications that use dynamic resources like blob URLs and lazy-loaded images.

Key Improvements:

• Blob URL Handling: Automatically detects, converts, and captures blob URLs (e.g., blob:http://...) used in images, videos, iframes, and other media elements
• Lazy-Loaded Image Support: Resolves and captures lazy-loaded images before taking snapshots
• Fully Async Pipeline: The entire DOM serialization process is now asynchronous, ensuring all dynamic resources are processed before snapshot completion

What Changed:

• PercyDOM.serialize() is now an async function that returns a Promise
• Blob URLs are automatically converted to Percy-hosted resources during serialization
• Lazy-loaded images are resolved and their final sources are captured
• All SDK integrations remain backward compatible (automation tools automatically handle Promise resolution per W3C WebDriver specification)
