Just a quick idea for the forum. How about in a user’s profile we have an option to select which Cycling ’74 products and versions we own/use. Then this can be displayed next to a username in the forum when posting (or hidden if the user doesn’t want to make it public). It’s mainly for selfish reasons as I keep getting disappointed when pasting compressed files in to Max5 only to find they use something only available in Max6 and I can’t use them at all.
My patches show up as Max 5 patches when I paste them, too. And I don’t have Max 5 on my system. I have a suspicion that if a patch contains no Max 6 specific features, it can be opened in Max 5 and the code is marked as such. It’s just a guess, but I’m a software engineer and that’s what I would do.
