Latest major additions:

• vMB203: now supports messaging (PFLAM)
• vMB202: using RadioLib, now supports the Sensecap T1000-E and Thinknode M3 (& M1)
• vMB179: added FANET id_method, auto-region by default, buzz at first GNSS fix
• vMB174: dual-protocol FANET (or P3I) plus FLARM (or ADS-L) modes
• vMB172: dual-protocol FLARM/ADS-L reception, some relaying in ADS-L protocol
• vMB171: revised relaying of ADS-B traffic, including "relay only" mode
• vMB166: added the ADS-L protocol
• vMB160: setting to control the time traffic not-heard-from is reported
• vMB159: capability to periodically transmit in an alternate protocol
• vMB155: collect statistics on reception range by relative direction
• vMB153: record compressed flight logs in flash memory (T-Beam & T-Echo)
• vMB152: settings stored in an editable text file
• vMB138: supports using add-on GNSS modules, on the T-Beam
• vMB130: supports the GNS5892R ADS-B receiver module, on the T-Beam
• vMB120: supports the latest 2024 radio protocol
• vMB110: added second serial port and data bridging (only on T-Beam)

Beyond Lyusupov's version:

• Collision prediction for circling aircraft
• Can set aircraft ID for self, ID to ignore, and ID to follow
• Support 3-level collision alarms via buzzer
• Can configure two simultaneous NMEA output destinations
• Settable baud rate for serial output
• Estimates wind while circling, uses for collision prediction
• Corrected frequency hopping and time slots
• Airborne devices can relay radio packets from landed aircraft
• Can adjust SoftRF settings within T-Echo (without an app)

And on the T-Beam specifically:

• Louder buzzer via 2-pin differential drive, or external
• Collision-danger traffic VOICE warnings!
• Includes strobe-control logic
• Option to connect to ambient WiFi network instead of creating one
• Option to send data as TCP client instead of TCP server
• Specify server's IP address for TCP client, and choice of 2 ports
• Ability to use WiFi TCP & UDP NMEA outputs simultaneously
• These WiFi options allow wireless output to XCvario
• Detect and use OLED display on either I2C port
• Winch mode ("aircraft type") with variable reported altitude

What is here:

Source code, and compiled binaries for ESP32 (T-Beam) and nRF52 (T-Echo, M1, M3 & T1000-E) (only). Note: a new T1000-E requires downgrading the bootloader before loading SoftRF.
