When I was ordering my new ESS "plug" Tesla looked at my log files and said I needed a firmware update. I quickly checked logs I had pulled a few months ago and noticed that the firmware I had was 4.6.8 40. I assumed this was the latest? "timestamp, firmware version 08/31/2014 10:53:05, 4.6.5 40 02/27/2015 15:56:32, 4.6.8 40 I emailed Tesla an extract from my logs showing the above and they said that I do not have the latest version and when my car is up and running to bring it to the SC... Certainly news to me...anybody else aware of this?
