Do .psd files have any stored metadata about historial of editions performed on them?

I edited a long time ago a .psd file, changing its brightenss, contrast, color balance, etc. Now I need to retouch some other pics that have the same darkness/dull color conditions in order to get exactly the same improvement effect than with the old one, but I don't remember what amount of color, brightness,contrast I did change, (in terms of parameters). What can I do? Is there a way to explore inside the .psd files to see what parameters change from one to another?. I still keep the original and the retouched version of the old pic, if that helps.... Thanks.
