v1.4.1

v1.4.1 — Correct Demo Trading Isolation

This release aligns the PHP SDK’s Demo Trading behavior with Bybit’s actual environment model: Demo Trading and Testnet are separate services with separate credentials and endpoints.

Fixed

• Testnet now always uses Bybit’s official global endpoints:
  • REST: https://api-testnet.bybit.com
  • WebSocket: wss://stream-testnet.bybit.com
• Removed unsupported regional Testnet routing for Japan and Hong Kong.
• Preserved strict separation between Testnet and Demo Trading; they cannot be enabled together.

Added

• BybitClient::demo() factory for creating an isolated Demo Trading client without manually configuring flags.
• requestDemoFundsSimple() helper for requesting or reducing funds for one supported Demo Trading coin: BTC, ETH, USDT, or USDC.
• getDemoApiKeyInfo() helper for reading the active Demo Trading API key information.
• subscribeGreeks() for the Demo Trading private WebSocket stream.
• Tests covering Demo Trading routing, the simplified funding payload, Demo API key access, and Testnet endpoint selection.

Notes

• Demo Trading REST requests use https://api-demo.bybit.com.
• Demo private WebSocket streams use wss://stream-demo.bybit.com/v5/private.
• Public Demo market data is served through the mainnet public WebSocket.
• Bybit WebSocket Trade is not available in Demo Trading.

See the Bybit Demo Trading documentation for the complete list of supported operations and service limitations.
