- Improved Portable Text editor copy‑pasting: better serialization of lists, links and filtering of unsupported objects for cross‑application paste.
- Added new developer APIs: unstable useObserveDocument hook, sticky params & intent operations, and enhanced presentation live‑query support for pt::text.
- Fixed critical bugs: stack overflow during GraphQL schema generation, history panel loading failures, and env‑undefined errors in embedded Studio environments.
