I’m currently working on a project with a few other devs that use Unity Pro 3.5.X, and it would make it much easier/‘safer’ to also be working in Unity Pro 3.5 (I do my work in Unity free right now, and submit my work piece-meal to them for testing/integration into the project). I would really like to buy Unity Pro 4.0 for other current/future projects, but would like to know if by doing so, if I would also be able to download Unity 3.5.X to use for this project as it nears completion. I would really not want to be forced to buy Unity Pro 3.5.X now, and then also buy Unity Pro 4.0.
Thanks in advance.
