Many have asked me if it is really necessary to switch over to data 47.4 from earlier used 46.3.
We have not seen noticeable issues with dataset 47.4 with 2011-2013 cars but yes you might need dataset 47.4 for the cars coming out of production now. Dataset 46.3 was very stable for earlier cars and unless you want to try new features, I dont see you to change over to new set immidiately. This is my personal opinion. Datasets will keep changing in future, that doesnt mean you should continue to chase them.
In reality, most of the people just want few features to be added and once they are done, they dont want further chnages.
