Changelog

Every change to the API's contract, newest first: operations, arguments, status codes, and the descriptions an MCP client reads. What counts as breaking is on Versioning.

26 October 2026

The reference is published, for /v1 as it stands.

Ten arguments that had no description now have one, over HTTP and over MCP alike:

  • reply_to_thread: thread_id
  • resolve_thread: thread_id, resolved
  • react_to_comment: comment_id, emoji
  • create_file: workspace_id
  • create_folder: workspace_id
  • rename_node: name
  • begin_upload: workspace_id
  • upload_image: workspace_id

Nothing else changed. No route, argument or status code moved.
