Hey all,I've been discussing this on-and off with @@Maveth and wondering if you need anything to help with the update option. 

This is the first I'm hearing about an "update option", but feel free to submit an enhancement request on Github if it's something you'd like to see added.

 

The website does have versioning data available in JSON, but could be adapted to plain text or whatever works better for C#.

Discussion is via git now so I'm closing this. https://github.com/rscustom/rocksmith-custom-song-toolkit/issues/152

Rocksmith Toolkit now have auto-update feature.

Thanks.

I see some great new features! :D
