The versions are essentially the series of evolution that his Rinkaku has gone through in the series. And from what we´ve seen, his is the only one we´ve seen evolve like this.

It´s called "versions" because they don´t go back to a previous form, it keeps the most recent one as standard.

Example:

Version 1: Tentacles.

Version 2: It develops joints.

Version 3: It grows a extra pair.

Version 4: It grows another pair and develops fingers. (and fromt he look of it, gans the ability to come out of his abdomen in front as well as back.)

Another common factor is that from stage two and onwards, it grows in size. (look at the berserking one of version 4 when he lashed out at Arima, both times. That was a mass far larger than Kaneki himself that went ham on IXA...so how on earth is all that contained inside of him?)

So in short, the versions are meant for the Rinkaku Kagune.

The other is for his Kakuja.

I prefer this the way it is now since it´s pretty good in showing how much he has developed during the story.
