2.68 scene opened in 2.70a Light Path: Diffuse, Glossy values changed?

I have an old scene made in 2.68 that I’m opening in 2.70a and in the Scene, Render Panel settings under Light Paths, the Diffuse and Glossy values are automatically changed from 128 (in 2.68) to 4 (in 2.70a). Is this a bug or have those values been scaled down somehow in 2.70a? Should I just manually raise them both back up to 128 in my 2.70a version of the scene?
