Sorry for announcing this late..
We've have released the new v10.11 maps that will include the changes of the French speed limits.
In France the speed limits on two-lane roads will be lowered from 90km/h (50mph) to 80km/h. It will affect around 460.000 km of roads (major & secondary).
This change was announced in January 2018 by the French Prime Minister and the official implementation date will be the 1st of July 2018. It is a two-year trial and the reform will be reviewed by July 1st 2020.
The map will be for PNDs, Motorcycle, Automotive, Truck and Camper maps.The maps 10.11 for Mobile apps will be released a bit later.
Update 6 June
: This map is now also available for the GO Mobile apps.
