Project versioning

Hello,

I wonder if there is option in IntelliJ IDEA like:

Let's say we have a project in version 1.0. We made working program. And now we wanna freeze it, since it's working, and create version 2 where I will modify it, or add functionality. Is some simple way to do that without using, for example, github? I don't wanna use external services and I wanna do it just for my "private" projects. The only way of doing it I can think of, is to copy whole folder manually.
