Beginning with 4Dv15, the R releases (ie 4Dv15R2) use a separate set of licenses prepended with the "R-" suffix. These set of licenses are their own set of unique licenses with their own number of features.



This means that, if originally the regular set of licenses provided 10 client connections, the R set of licenses will provide its own set of 10 client connections for the R versions, however this does not mean that one server can provide 20 client connections.
