As far as I am concerned, everything worked out fine.
Just a small lag between the 100% download and the actual installation process.
This version brings minor improvements to the previous 2020.8.1, namely a better voice recognition, some additional interface languages and expanded access to non-Tesla charging stations (which where introduced in the 8.1).
Mine does not have sentry mode so I cannot say if this could cause a problem.
Good luck to all
