Domain Rating history

Every recorded Ahrefs Domain Rating, one per UTC day, ascending — the series behind the /stats chart. current is the latest reading (null until one is set). change compares the latest reading to the most recent one with a different value — the last actual step — and is null while fewer than two exist or every reading is equal. growth compares the latest reading to the very first and is null with fewer than two. History starts at the first recorded reading and grows by one row per day the DR is checked.
