Changelog

Changes to what a client sends to Advisor or receives from it, newest first. Changes to the data itself, such as a new compilation, are not listed: every answer carries its own currency. See Data currency and status.

October 2026

• get_amendment_history pages its versions. versions_limit and versions_offset, newest first, with versions_page. Titles with long histories, such as the Privacy Act 1988, were refused as too large and now answer.
• uncommenced_amendments says where the amending text is held. text_available and amending_instrument_held are true where get_uncommenced_text can return the amending law's items.
• Long lists are cut to fit, not refused. A response whose items are in one list keeps its first items and says so in truncated and truncation_note.
• get_portfolio_functions_and_legislation lists no legislation per function. function_id and response_format: "detailed" are withdrawn and refused: the Order allocates legislation to portfolios, not functions.
• Centrality counts only the Order's allocations in its breadth term, not text-similarity links between titles and functions.
• maker.office reads in full where it was cut before "delegate", for example "Manager, Continued Operational Safety, a delegate of the Civil Aviation Safety Authority".
• Streamable HTTP endpoint. https://advisor.lawatlas.ai/api/mcp-http/mcp, stateless, alongside the SSE endpoint. Required by clients that do not support SSE, such as OpenAI Codex.
• Partner API keys. Organisations and clients on the partner page; bearer keys beginning lap_; scopes; per-client rate limits returning RATE_LIMITED; TERMS_REQUIRED for Hansard. See Partner API keys.
• Errors are not billed. A call that returns an error, is refused or fails is not billed; an answer is billed once.
• Developer documentation at lawatlas.ai/docs, with llms.txt and llms-full.txt.

September and October 2026

• Law not in force is never served. TITLE_NOT_IN_FORCE, and a status block with confirmed_with_frl_at on every title and served provision.
• The compilation block. register_id, compilation_no, check_date and state on served text.
• The error envelope with stable code values and no internal detail. See Errors and status codes.

Note: Each payload carries a schema_version. It differs between tools and rises when a tool's payload changes.
