# 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](/docs/versioning).

## 26 October 2026

<!-- contract: de7574f716898672 -->

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.
