Features:
- The rear USB port can now be switched between Host (Master) and Slave modes via the menu.
- In USB Slave mode, added composite USB gadget support with a virtual COM port (CAT control) and a virtual audio device for PC connection.
- Reworked the internal DSP filters: latency reduced by 20 ms, and the RX/TX passband lower limit was extended down to 50 Hz.
- Improved unwanted sideband suppression to -90 dB across the entire audio range.
- RIT/XIT are now automatically disabled in Split mode.
- Redesigned the boot and startup splash screens.
- Improved the automatic update mechanism for the kernel and other system components.
- Optimised DSP code to reduce memory and core utiliztions.
- Added Recovery Mode: to recover a bricked device, power on the transceiver while holding the PTT pedal. The transceiver will boot from the recovery partition and connect to the remote server for troubleshooting.
- Total measured end-to-end latency from the antenna input to the PC audio output in USB mode is 128 ms (EAX mode: 150 ms). Those valuse wil be improved in tne next relases.
