v0.5.1 — contract 4.3.1

[0.5.1] — 2026-10-15

Generated from contract 4.3.1 (was 4.3.0). Nothing breaks.

Added

• client.klines(symbol, timeframe, live=True) in Python, client.klines({ symbol, timeframe, live: true }) in TypeScript: the candle in progress, is_closed: false, its OHLC from the
  same reference market and its volumes provisional until it closes.

Changed

• Docstrings and JSDoc follow the contract texts: a 1m candle is closed about 5 s after its end
  (it was about 21 s), a 1m order book about 2 s after.
