Oct 8, 04:00:01 GMT+0 - Identified - Maintenance is now in progress Oct 6, 19:56:15 GMT+0 - Identified - A scheduled CLOB release requires a brief restart, with downtime of up to \~10 minutes.

Update to the live-sports order taker delay implementation (orders that return status "delayed"). Before: Held orders were released together at the top of each second. Taker's actual hold was anywhere from 0 to 1s depending on when in the second the order was sent. After: Each held order is released exactly 1s (the market's seconds\_delay) after the engine receive it. Why: Align with standard delay practices thereby making the hold consistent for all takers. This will also allow fills to arrive as a steady stream instead of a burst at the top of each second. Scope: this only applies to the live-sports seconds\_delay hold. The taker delay amount itself is unchanged (orders are still held for seconds\_delay and still return "delayed"), and the crypto taker delay is not affected at all.
