A Huobi and HTX signing defect mixed the local date with the UTC time, so a host running outside UTC had every private request fail for part of the day. It read as an intermittent authentication problem, and it was a two-line fix…
Four Kraken defects fixed in 2026.9: the spot WebSocket client was speaking v1 while connected to a v2 endpoint, Futures REST orders went out as GET with the signed body discarded, and private subscriptions never replayed after a reconnect…
sgcWebSockets 2026.9.0 adds the sgcHTML Design Surface, so pages can be composed visually on a VCL form instead of only in code, using the exact same components and producing the exact same HTML…
