Faith and Life Old version vs. revised?

Just curious - what if anything was changed between the 2 versions?

I am getting some free locally, and they are the old version mostly.

It's been a couple of yers since I compared these two versions but I do remember preferring the older edition. The questions in the newer edition seemed to be written at a much higher level than the text and often without careful consideration of the material covered in the chapter. HTH!
