# Changelog

Changes to the B3OS beta API, products and docs, newest first. Breaking changes are announced here 14 days before they ship.

Breaking changes appear here at least 14 days before they take effect, with the date of the `B3OS-Version` that introduces them.

**Docs for the v0.1 API contract**

The first version of these docs, written against the v0.1 API contract: quickstarts, concepts, a section for each product, the generated API reference with 210 operations, the error catalog with 140 codes, and the SDK, CLI and MCP pages.

  The contract covers vision (including Firecrawl v1 and v2 compatibility), render, sandboxes, routines, actions and triggers, vault, infer (OpenAI-compatible), webhooks, the request log, and keys, usage and limits. Operations planned for later in the beta answer `501 not_implemented` until they ship; the [beta contract](/concepts/beta) lists them.
