Yes but I think it has using been using the Drag n Drop render for each track, though now it should be moving the the Audio > Export Song As Audio file..
This will also give an option to Normalize and Acidize as well as Set Mix to Flat Dry and Center, the midi is instant via drag n drop so that method may still be used for midi/realcharts/drumcharts.
Hover over the file or right click properties > details
