Hi folks. I bought Gunbot back in 2017, maybe August when BTC was around $4000, spending 0.1 BTC at the time. In those days there was only one license/version, but now there are four? I've been out of the scene and living under a rock since January 2018. My robot is installed up on Amazon Web Services. My question is how do i get up to date with the latest version for my license?
