A changelog of verified official facts: UK tax and National Insurance thresholds, exam specifications, and official vehicle datasets (French RappelConso recalls, Japanese MLIT recalls and complaints), plus central-bank policy rates (Bank of England, Fed, ECB). Each entry records what changed (from → to), when it took effect, the official source, the date it was verified, and a maintainer note. Entries are generated by scripts from committed data files and annotated by the maintainer — never written from memory. Coverage starts 2026-08-31.
Also available as RSS, Atom, JSON at /api/changes?since=YYYY-MM-DD, or over MCP: the what_changed_since tool at POST /api/mcp takes a date (an agent's training cutoff) and returns the entries after it.
