Changelog

1.13 (latest)

+Added the ability to install GMiner on Bitmain stock firmware from late February 2024, including firmware from 2025 (no longer required to downgrade the stock device to an older firmware version)

+Improved logic for returning from a backup pool to the main

+Added S21+ submodels support: A3HB70702, A3HB70703

1.12

+Improved logic for switching to backup pools, detects domain blocking by the provider and switching to the next pool

+Reworked the option to ignore broken temperature sensors. Now, at least one working temperature sensor is required for mining. Specifying a minimum number of working sensors is no longer required

+Added an option to enable/disable DNS over HTTPS, allowing you to hide pool addresses from the provider

1.11

+Added power efficiency mode for T21/S21/S21+/S21 Pro/S21 XP, it can be enabled in performance section. In our tests this mode improved power efficiency by 0.5-1J/T (S21+ 235T)

1.10

+Improved performance optimizer in mining mode

1.09

Miner:

+Added option to disable performance optimization after auto-tuning and in manual mode

+Added option to ignore abnormally slow chips during auto-tuning and during performance monitoring

Toolkit:

+Fixed bug that could cause random operation failures (update, configuration, reboot, etc
