Different documentation per version

Hi,

I am using Shapes for a while now and because I am pretty lazy updating (especially because I tweaked the shaders for my very special use case) I use quite an old version of Shapes. However, not only the package is evolving but also the documentation and I am more and more confused because of the divergence between documentation version and my plugin version.

So maybe it would be cool to have a version selector for the documentation? Just in the same way the Unity Manual has an Engine version selector at its top left corner! Or would this require too much effort for the benefit it would generate?

Thanks for the great work!
