What's New

Fixes Studio crashes outside Vite hosts and improves engine stability with finite video slots and cache preservation.

New Features

  • Added retry logic for Producer capture when CDP refuses screenshots

Improvements

  • Engine now holds finite video slots past EOF
  • Long-capture caches are now preserved effectively
  • Improved error handling for backup failures in Studio

Bug Fixes

  • Studio no longer crashes when loaded outside a Vite host
  • Engine now holds finite video slots past EOF
  • Keep a render's dependent extraction-cache entry alive during long captures
  • Tell an opaque document how to actually get its Web Audio back

Upgrade Notes

No configuration changes are required. The player now handles non-Vite ESM hosts gracefully, and engine caches are preserved more effectively.
