I don't know of a single resource that lists all the changes over such a
wide range of versions.  You can probably dig up changelogs here and
there or documentation of most differences between each big release, but
you'll be collating things yourself.

My sincere suggestion is that you abandon that book if possible since so
much has changed between Ruby 1.7 and 2.0.  That book is probably going
to trip you up in subtle ways as much as anything.

While the book at the following URL is also a bit outdated, it's still
better for you since it covers Ruby 1.8:

  http://www.ruby-doc.org/docs/ProgrammingRuby/

Here is another reference with free information:

  http://www.ruby-lang.org/en/documentation/

You can also check through the ruby-talk forum other suggestions for
reading material.
