Chris,
The ver 3.4 that was discussed is the new hardware version of the printed circuit board. You are correct about the firmware/software being easily upgradable to different versions, which has contributed to the popularity of the NanoVNA units. However, if you want the latest and greatest hardware changes then you have to purchase a NanoVNA-H with a ver 3.4 printed circuit board. hugen posted some screenshots last night in another message thread that show improved ver 3.4 PCB performance out to 1500 MHz.
