Resolve 19 or 18 Beginner Guide?

Hi everyone,
I have found the free tutorials and I am working through them! I have a question though.. I noticed that in the PDF book tutorial section that the series is based on Resolve version 18 except for the beginners guide which is based upon Resolve 19.. Is there a difference between them both? If so, is there a way I could download and carry on with the Resolve 18 version of the beginner guide?
Thanks,
Trav
