Here’s the latest I-level versions for BMW ISTA. The i3 is I001.
I3 drive me crazy … even with a new 12v

Thanks! Good stuff!
Do you know the meaning of the V4.0.x numbers at the end of each i-step level?
The i-step level of our i3 is I001-22-11-550 which is just one level newer than the i-step level corresponding to my ISTA 4.39.20. I'm hoping that this slight mismatch would not have a noticeable effect on the performance of ISTA 4.39.20 with our i3, but I would prefer to have ISTA 4.40 or later.

I have no idea what the v4.0.x numbers mean, sorry. It doesn't seem to follow any pattern.
ISTA 4.39.20 was the last version of ISTA that didn't require an activation license. Luckily enough, that version works fine with our "now" older BMW's. The I-level software (SDP) is somewhat separate and can be loaded into an older version of ISTA. For example, earlier this year I used ISTA 4.39.20 with the 4.47.1x SDP taking my I3 to the 24-03 I-level. Next month when I do its annual service and tire swap for winter, I will update the SDP to 4.50.1x or whatever is the latest and have the 24-11 I-level.
As far as I know, a newer ISTA software version is only required when working with the newest vehicles.
The last few I-level updates I've done (after 2021) have only really updated the Idrive (headunit) so I don't think there's much being worked on for the I3. The Idrive is probably being updated since it's used in many different BMWs.
And just an FYI, the BMW ISTA software is available to anyone for a fee. https://bmwtechinfo.bmwgroup.com/
Thanks for that confirmation!
Does this mean that anyone who subscribes to the BMW TIS, even for only 1 day, would be able to download ISTA?

Yes, you still need the hardware (ICOM) if you want to connect to the vehicle. You can still use ISTA for repair procedures and wiring diagrams without hardware.
You also have access to all the service bulletins.
