-### Transponder firmware
+## Transponder firmware
 
 This is a vanilla Eclipse CDT project. Import it into your workspace and (assuming you have ARM cross compiler installed) it should be straightforward.
 
 The application is mainly interrupt driven, with a single event queue being dispatched by a FreeRTOS task. I did this mainly to take advantage of the robust queues in the OS.
+
+### Key updates
+
+ - With board 6.1 bringup complete, the system now runs FreeRTOS 10. 
+ - DFU can be achieved by jumping directly into the ROM bootloader, so there is no need for hardware to manipulate the BOOT0 pin
+ - The TX_DISABLE signal is now supported
