I buy Parallels 15 licence 3 weeks ago, 19/07/2020, now there is a new version and I have to pay another 49 euro to upgrade to it... Feels like a money grab. Not even a discounted upgrade to reflect the 3 weeks of use I got before the new version was released...
Hey, I was able upgrade for free there is a link on the page below https://www.parallels.com/products/desktop/ hope it helps!
