Formatting of errors changed to include the binding name (SourceObject.SourceProperty <-/<->/-> DestObject.DestProperty). Errors are now stored in the binding object again.
Renamed GetConversionFunctionPath to SourceToDestinationFunctionPath and SetConversionFunctionPath to DestinationToSourceFunctionPath.
