Hi, thanks.
In some of the apps you mention they advert you when an update is available (Contrail, ORBX Central). For the WT and FBS-a320 you should check for yourself in their places. But with FSDT, unless you run the updater, I'm at a loss, because even after running the FSDT Updater I don't exactly know if something was updated or simply overwritten. Also, if you also have FSDT products for P3D installed, you don't exactly know if the updates are for P3D or MSFS.
I'm not getting either any notifications from SimMarket about FSDT updates (having checked the option to receive notifications when a product is updated).
Cheers, Ed
