So, the 1.1.4 version from the marketplace is just the version that points 3rd party planes that come with the standard GNS to the WT GNS. Version 1.1.2 is the WT GNS that is included in the base sim planes. IIRC the piper arrow now comes with the WT GNS as a standard, so it would be using version 1.1.2.
