v1.5.21

What's Changed

• Thermal Graph & Background Telemetry Fix (#65): Aligned THERMAL_ONLY graph mode with hardware GPU sensors using dynamic detection (hasGpu) and updated the legend label to Thermal Only (CPU, GPU, Skin, Battery). Maintained continuous background thermal & battery telemetry during active Gaming Mode sessions to eliminate 0.0° flatline telemetry gaps.
• Ping Timeout & Read Status Handling (#70): Added -w 2 timeout deadline to ICMP echo calls and integrated pingReadStatus (MetricReadStatus) into PingMonitor and MetricModule. Overlay now displays timeout state during packet loss instead of misleading -- ms.
