Shimano STePS DU-E8000 firmware version history

[MassDeduction]

Does anyone have a link to a version history for the firmware for the STePS 8000 motor? Or any off hand thoughts on what you lose if you're on firmware 4.3.2 vs. people who're on the current firmware?

Here is the link to the version history:

As far as what you will lose on firmware 4.3.2 vs 4.7.1, I believe you may lose compatibility with newer STEPS components that were released after 4.3.2 was released (Dec 21, 2017). In addition, you will lose any bug fixes and updates made which you will find briefly described in the version history.

I found that when I tried downgrading to 4.3.2 on a bike with a e8035 battery and EW-SW100 external power button that I could not turn the bike on with the external power button. I assumed this was because the e8035 battery and EW-SW100 external power button were released after 4.3.2 and thus were not supported by that version of the firmware, but I do not know that for sure to be true.

That makes perfect sense, and the screens/controllers for E6100/E7000 are specifically highlighted as not working with 4.3.2 which speaks to your eperience. The bike I've been looking at has an older battery and screen. Any bug fixes or feature additions of note that anyone can name between those revisions?

Is it possible to downgrade to 4.3.2 without computer ?
