    Opening CS6 documents in CS4




      When I create a psd in CS6, and then open it in CS4, I get this error:


      This document contains unknown data which will be discarded to keep layers editable. To preserve the original appearance instead, choose Flatten to load composite data as a flattened image.


      And then I have the options to Flatten or Keep Layers. If I Keep Layers, things seem OK, but I'm wondering what data is being lost. I'm asking this question because I'd like to begin working in CS6, but I want to make sure anything I do in CS6 will still be editable in CS4 in case I don't buy CS6 right away when the beta trial period is over.
