I just found a post in the German Coffee Forum about a software/firmware update for the Bianca.
Here's the link:

And here is the text translated with Google (and not double checked) - if there is some wrong translation, you can ask and I can try to properly translate individual sentences:
"Lelit has released firmware 4.07c, which is now implemented in all possible machines. I HAVE BEEN COMPOSED HERE OVER THE LAST MONTHS OF DEVELOPMENT, WHICH HAS BEEN FUN. The changes are impressive:
- economy mode:
Press 3sec on the "-" button, which saves the way through the menu. Since I do this several times a day, I'm pretty happy.
- Standby mode:
With the shortcut "+" and "-" for 3 seconds, the machine goes into standby -> steam boiler, brewing boiler 80 ° C.
I tend not to use this mode, but it is a huge improvement to the old menu, where you can only set a time that specifies how many minutes of inactivity the standby mode will start.
- water reserve:
So far, there was no direct stop when the tank was quickly empty, but sometimes it was still possible that the supply did not come to the end. Well, when the water runs out, a water drop symbol appears during the reference, so that you could theoretically refill. In practice, however, it is hardly necessary since the cover continues for up to 60 seconds. If you don't pull an ultra-long slayer shot, you can get there well, otherwise you have enough time to refill.
- Shott timer:
The Shottimer was hidden relatively quickly in the old firmware. Now the time is displayed for 20sec. I got along well with the first solution, but apparently you also complained to customers. It's a good thing that you get into the menu as normal during the 20sec.
- steam temperature:
The steam boiler now goes up to 135 °. This is brutal and absolutely suitable for gastro, if you want to froth larger jugs. I do not see any difference here to the LMs etc.
- Heating program:
This has taken up a lot of the time. So far it worked perfectly with cold machine and dual boiler operation, there was a bit of overheating if the machine still had a lot of residual heat or it was only used in single boiler operation, see my graphics at the beginning of the thread, where I was working for the single boiler Company described a workaround. So far, there was only a threshold temperature of residual heat, where the standard heating program was still activated or was not run at all. If you were just below it, the machine overheated as a result, just above it without a heating program it took just as long or even longer to heat up than a cold machine with a heating program. So you had to wait longer for residual heat than for a cold machine.
Now the machine differentiates fundamentally whether it works in single or dual boiler mode and has two thresholds for the residual heat in order to run different programs. For every boiler mode there is a full heating program, a shortened and none at all for residual heat above 75 ° C.
Especially with residual heat in the middle region with the short heating program, if the machine e.g. an hour was up, it only takes about 5-6 minutes.
All in all, the new firmware significantly improves the Bianca once again.
To upgrade you have to replace or have the LCC unit replaced. It is quickly done by yourself, except for the case, you don't have to remove anything. Lelit has published a video on this. To be honest, I don't know how much this part costs, I would in any case talk to my seller about it, maybe there will be a discount as an upgrade customer.
