What's New
Fixes Studio crashes, HDR color accuracy, and prevents orphan worker processes.
New Features
- HDR auto-promotion reporting in `check --json` command.
- Environment variable `HYPERFRAMES_RENDER_DETACHED` for intentional detached renders.
Improvements
- Forced `--sdr` renders tone-map HDR sources to match Studio preview colors.
- Studio preview and render downloads now work for non-Latin-1 filenames.
- Render workers no longer survive as orphans after Ctrl-C or parent exit.
Bug Fixes
- Studio no longer crashes when loaded outside a Vite host (e.g., MCP sessions).
- Engine holds finite video slots past End of File (EOF).
- Long-capture caches are preserved effectively.
- Render workers no longer survive as orphans after Ctrl-C or parent exit.
- Forced `--sdr` renders tone-map HDR sources to fix color cast.
Upgrade Notes
If you previously relied on workers surviving parent exit, use `HYPERFRAMES_RENDER_DETACHED=1`. Otherwise, the default behavior now ensures workers terminate cleanly.
