This release resolves two issues introduced in v3.80, and brings a stability improvement for the new Cerbo GX MK3, along with Modbus-TCP improvements, listed below.

Fixes and improvements

• Classic UI: fixes the missing AC and DC values of VE.Bus devices in the device list (broken in v3.80).
• Pytes batteries: installers can now enable Shared Voltage Sense.
• Cerbo GX MK3: no longer reboots while plenty of free memory remains, and about 19 MB more RAM is available. Further memory improvements are in progress.

Modbus-TCP

• Register 232, /MicroGrid/OperationSwitcher/Operation, is writable again. It was accidentally made read-only when added in v3.80.
• New register 235: MicroGrid AllowBlackStart.
• New register 129: controls the VE.Bus Weak AC Input config setting.
