NautilusTrader 1.184.0 Beta

Released on 22nd January 2024 (UTC).

Enhancements

• Added LogLevel.OFF (matches the Rust tracing log levels)
• Added init_logging function with sensible defaults to initialize the Rust implemented logging system
• Updated Binance Futures enum members for BinanceFuturesContractType and BinanceFuturesPositionUpdateReason
• Improved log header using the sysinfo crate (adds swap space metrics and a PID identifier)
• Removed Python dependency on psutil

Breaking Changes

• Removed clock parameter from Logger (no dependency on Clock anymore)
• Renamed LoggerAdapter to Logger (and removed old Logger class)
• Renamed Logger component_name parameter to name (matches Python built-in logging API)
• Renamed OptionKind kind parameter and property to option_kind (better clarity)
• Renamed OptionsContract Arrow schema field kind to option_kind
• Changed level_file log level to OFF (file logging is off by default)
