I am just curious as to what the current version is and do new songs automatically get downloaded and added to the game?
The current version is 2016.1.3.0. If you have a version with the launcher installed, you can check the "Update" button to see if you can get any updates.
As for automatic downloads, the ones we deem "finished" get added with any new update, but you have to download the Beta releases individually. You can find those on the right side of the launcher.
It says ultrastar version 1.3.5 and if I update it says it is up to date
