🆕 Expanded PSU Support
• Added support for PSU types: 0xc4, 0x69

⚙️ New Features & Enhancements
• Default Thermal Safety for Hydro/Immersion: To ensure hardware longevity, the default Critical Temperature for all Hydro and Immersion-cooled models is now set to 80°C upon firmware installation.
• Expanded Localization: Added support for two new languages: Portuguese (pt) and Georgian (ka).
• Expanded Startup & Resume Delay: The Mining startup delay (configurable in seconds) now also applies to Resume mining. This ensures a controlled staggered start for power stability, whether the miner is powering on for the first time or resuming after a pause.
• Rollback to Stock: Added an option to automatically wipe system logs when performing a “Rollback to Stock” operation.
• Thermal Protection: Implemented critical PSU temperature monitoring. The system will now automatically lower/raise presets to prevent PSU overheating.
• Safety Shutdowns: Miner now switches to “Failure State” immediately upon detecting sensor errors or overheating.
• Autotune Optimization: Improved autotune algorithms for better stability and efficiency.
• Voltage Management: Reduced voltage offsets during frequency tuning for more precise power control.
• Enhanced Diagnostics: Updated temperature sensor validation logic and fixed widespread issues related to global setting applications.
• Stability Fixes: Resolved the “Random DevFee penalty” bug.

🔧 New Configuration Options
• Offline Mining: Allows the miner to continue operating without an internet connection (Note: hashrate produced offline is not submitted to pools).
• Delayed Resume: Added an optional delay before mining resumes.
• Advanced Power Management: New throttle command: Allows users to manually scale down mining power. For example, setting the throttle to 50% will reduce a 200TH miner to 100TH, allowing for immediate power savings without stopping the miner.
• Hydro-Specific Settings: Added “Minimum water temperature for startup” for liquid-cooled systems.
• New Cooling Widget: Added a dedicated dashboard widget for Hydro and Immersion cooling systems.
• Advanced Logic:
• Added “Retune on chain break” option.
• Added “Allow disable chain without PICs” option.
• Preset Tuning Timestamps: The interface now displays the completion date for autotuned presets. Note: This applies only to tuning sessions performed on this version or later. Presets tuned in previous versions will not display a date.
• Power Limit: Added a new Power Limit functionality. The miner will now strictly adhere to a user-defined wattage cap, automatically lowering the overclock (frequency/voltage) if power consumption attempts to exceed the limit.

🔧 Bug Fixes
• NTP Synchronization: Added new time-server pools (pool.ntp.org) to ensure more reliable system clock synchronization and faster connection to mining pools.
• Factory Reset Protection: Fixed an issue where the device serial number was accidentally deleted during a factory reset.
• Fixed issues involving the cloning of miner settings.
• Resolved a dashboard freezing bug occurring when querying third-party monitoring services.
• Configuration Persistence: Fixed an issue where miner configuration changes failed to save correctly.
• Network Settings: Fixed an issue with reading and displaying Network settings.

This ensures that IP addresses, gateway configurations, and other network parameters are correctly retrieved from the system and accurately shown in the web interface.

⚠️ Deprecated & Removed Features
• Removed: higher-volt-offset option.
• UI Cleanup: Widget settings have been removed from the interface for a more streamlined experience.
• Removed “Modded PSU” Setting: The option to manually select a Modded PSU has been removed from the configuration.

💻 API Changes
• Method Migration: The find-miner method is now deprecated.
• New Route: Introduced ‘locate-miner’. This new method includes a parameter to explicitly enable or disable the miner locator (LED), providing better control via the API.
• New Route: Added the ‘boards’ route to the API for more granular hashboard data retrieval.
• New Route: ‘/mining/throttle’ added a specific route to control the new throttling/power scaling feature.
• Route Removal: The ‘/chips’ route has been permanently removed from the API.
• Field Renaming: To improve clarity, the API field ‘remain_stopped_on_reboot’ has been renamed to ‘restore_miner_state_on_reboot’.
