New firmware out :
RB03PR.01.08.006.5058
its alredy listed on italian dyson page for manually updating your unit
download https://ota-firmware.cp.dyson.com/277/WF00/latest/download.html
note : at the moment the unit will reverse to the latest older version if auto update is turned on.

The most important thing about this is that the unit is now doing less turns and is doing longer straight lines.
This should improve runtime but more important improves the cleaning result even more.
Turns on surfaces like carpets that are having a pile direction (if you clean against the pile cleaning results are pretty worse - even with stick vacs or casual units).
