Now let's look at Expressive:
Enjoy the benefits of our lifetime license and get access to all features and
upcoming updates with a one-off payment.
Get access to all features AND UPCOMING UPDATES. Nobody is going to assume this is restricted to the current major version, and having this "gotcha" in the FAQ is going to come with some headache when customers discover "All upcoming updates" doesn't really mean what it says.
