Release 2 firmware versions are available for download with descriptions of what they do via the link in the FAQs in post #3. So I don't know what you are asking about. There is no special firmware that works on just one version that I am aware of. All of the cameras currently being shipped (original and jumbo size) are running Rel 2 firmware to my knowledge.
When I approached Diana for a cam, 50S/S/C firmware was not made known to me. The default firmware that the manufacturer would load was the Rel 2 4Gb continuous without date/time stamp. I needed the date/time stamp feature so I've asked her whether she would be able to load 20S/S/C firmware. She said it was not possible.
If you are using this cam as a car dvr, the firmware with 50S/S/C will suit the bill. You do not need a jumbo since the cam is connected to car charger.
