# Changelog

The API and the MCP server share one version. A breaking change gets a new version, and a deprecation notice here with its date before it takes effect. The spec for the current version is [https://www.closefinch.com/openapi.json](https://www.closefinch.com/openapi.json).

What's shipped in the product itself is in the [product changelog](https://www.closefinch.com/changelog).

## 0.1.0 (2026-11-06)

- Every API and MCP error carries `fix` and `docs` (a link to its section of /docs/errors); a missing key says where to get one.
- `ra sandbox create`: an agent gets a sandbox organization and a limited key from the CLI, saved as a profile.
- `ra_billing_upgrade_link` / `POST /v1/billing/upgrade-link`: an agent suggests a paid plan; an owner reviews and pays.
- MCP tool descriptions are written task first, each with an example call.
- `ra_templates_list` lists agent templates again (its route is `/v1/agent-templates`).
- Developer docs: quickstarts per client, task recipes, approvals and policy, and a reference page per MCP tool and API resource.
- MCP server: protocol versions 2025-06-18 and 2025-03-26.

**Deprecations:** none.
