A new upgrade is available today. The download to the phone via home wifi took about a minute (3gb in size). The transfer to from my phone to the Mini via Bluetooth took about 10 minutes. Installation took another 10 minutes. If you start the car immediately after the install, it will still need to download and install the latest language set (US English for me) to enable the Mini Voice assistant upgrade. The new Go Kart feature set was available immediately. Use the Mini App on your phone to get full details of each feature upgrade noted in the summary of the Release Notes image.

 

Nice! But my app still says 07/2024.40 is the latest software version...

 

I talked to customer care on another point (they say in a future release of software they will add home link believe it or not - would imply the transmitter is in car and they are going to implement software buttons maybe) but the agent said they phase roll out the upgrades across servers so could be why some have received before others. Also noticed OP has ICE Countryman whereas I am EV and wonder if the two on different release schedule as well?
