I chuckled when I saw this thread. In the past, I have complained that I thought Corona was upgrading full versions too fast. Ha. I think Tom makes a great point about a maturing application becoming a product with refinements, speed boosts and the occasional major feature. I mean, how many groundbreaking features does Microsoft add to Word these days?
In the old days, major versions of 3D apps always boasted about render speed increases. I don't see that much with Corona right now. Mainly relying on the number of cores on the system being used. If the features stayed the same, but render speed was increased by 50% or more, that is a game-changer for most. Corona is already great and artists are making amazing images now, but if they can do the same thing a lot faster? Boom.
