Disappointed with Vacuum firmware 4.3.3_1122

Seriously, Xiaomi is teaching users to avoid upgrading devices. But it should not be this way.

The previous firmware was good. The floor got cleaned every time. Now the vacuum does crazy movements at the end of a job on each room. It also leaves tracks, areas with dirt as if the walk distance has increased wider than its radios or something.

An also, PUT THE FUCKING AND DESCRIPTIVE CHANGE LOG in the screen where the user receives the firmware upgrade. So we can decide if it is a security fix that has to be applied, something that will help or just a random code that is going to break the normal functionality
