## What changed
- Make `thread/turns/list`, `thread/items/list`, and `thread/revert` available
without the experimental API capability.
- Stabilize `thread/reverted`, `thread.historyMode`, and the pagination fields
used by `thread/resume` and `thread/fork`.
- Publish the promoted requests, responses, and fields in the stable JSON and
TypeScript schemas, and update the app-server documentation accordingly.
