Product updates as they ship.
POST /orders, /orders/batch, and /orders/multi-leg now require a client-supplied idempotencyKey and reject requests without one. Use a fresh key per logical order and reuse it only to retry the identical request — identical retries replay the stored response, and a changed payload with the same key returns 409.
When your positions in logically linked markets guarantee a payout, new trades now require fewer credits. The trade panel previews credits needed and ALL savings before you place an order, and your portfolio shows payout floors and outstanding advances. API responses include the same data: relationship endpoints, portfolio collateral, and per-order execution economics. Organization managers can also review and manage market relationships from the new ALL tab in their dashboard.
Product updates relevant to users will be published here as they ship, first on staging and then in production.
