Changelog from v3.12_448:

• Improved: Improved firmware loading process, requiring NiceHashTools v1.1 and up
• Improved: Improved tuning algorithm, efficiency and safety checks
• Improved: Allows miners to boot and initialise when one or more dashboards have EEPROM errors
• Improved: Miners with only 1 working fan will enter sleep mode automatically after reboot to avoid hardware damage
• Improved: Miners with only 2 working fans will mine at half hashrate to avoid hardware damage
• Improved: Miners start to mine during the preheat phase, utilizing the power more effectively
• Improved: Miner will load the previous tuning profile after a reboot. In case the resulting hashrate is low, an automatic re-tune is triggered
• Improved: Minor UI/UX improvements
• Fixed: Pool settings are correctly restored when uninstalling NiceHash Firmware
• Fixed: LED indicator now more closely matches stock behaviour
• Fixed: Fixed an issue with S19 Pro miners creating an excess amount of duplicate shares leading to low hashrate
• Added: Tuning progress bar
• Added: Support for Alphaminer PSUs
• Added: Support for S21 BHB68606 variant
• Added: Option to stop mining in case all pools are dead to conserve power. Mining will automatically resume once at least one pool becomes available
