Having just bought SkySafari Pro 6 on 29 Oct 2021 and not even had time to fully evaluate it, and being a long time user of Starrynight Pro Plus 8, I was really annoyed that SkySafari Pro 7 was released today.....and I either have to pay for the upgrade or not upgrade!
This is dreadful practice. Why wasn't (at least!) offered a free upgrade in such circumstances which is the normal practice?
