AI Summary

This release enhances Studio by exposing live editing state to agentic browsers and enforcing stricter error handling to prevent silent render failures. It introduces a WebMCP polyfill for broader compatibility and ensures nested runtime videos retain their unique identities.

Key Highlights

  • Studio exposes live editing state to agentic browsers (WebMCP).
  • Renders now fail explicitly when sub-compositions, media extraction, or validation break, instead of succeeding silently.
  • Added a WebMCP polyfill to support browsers lacking native WebMCP implementation.
  • Nested runtime videos are now kept distinct.

Breaking Changes

  • Renders that previously succeeded silently due to sub-composition or media extraction errors will now fail.
  • Nested runtime video identity handling has changed to maintain distinct identities.

New Features

  • Studio exposes live state to agentic browsers.
  • WebMCP polyfill fallback for browsers without native support.
