Assigned Version 4 but Version 3.3.1 shows up in projectBrowser Info Environment
The only difference between versions 3.3.1 and 4 is that 4 works with concrete v9 but 3.3.1 doesn't.
When it came time to adapt my packages to concrete v9 I had a choice between making a version that would work everywhere or making a separate version. The latter was simpler so that's what I did.
Other than that they are exactly the same. If you're on concrete v8 you'll get 3.3.1 and if you are on concrete v9 you'll get 4.
Let me know if anything is not clear.
