TYPOlight 2.6.0 / 2.9.3

Hello,

I've bought Leo Feyer's TYPOlight book about 1.5 years ago, there's a CD with version 2.6.0 included. I had no time to start immediately but I knew, Tl is the way to go. Now I started to read (nice book) and this is my question:

What does make more sense, working with this book with the included 2.6.0-installation, or downloading the newest version 2.9.3 and use it alongside the book?

Thanks!

I'd do it with the newest version, as theres been a lot of changes since then.
