New edition with new/changed text

[JSWolf]

I'm wondering if a new edition of a book should be combined with the old edition. The new edition has updates/added bits The following is from the author on what was done to the book.

* The most important bit: adjustment of technology and background in the book(s) to reflect what's routinely been part of young readers' lives, starting in 2008
* Some minor editing of material that struck me while revising as clumsy or ineffective
* Some additional material (not vast amounts)
* Repair and reconstruction of what has for a long time been a very broken, inconsistent and frankly dysfunctional timeline

Now I'm thinking it should not be combined with the older version. Am I correct in thinking this since it's not just an alternate cover, but a new version with new/changed text?

That is the cover and link for the new edition should it be deemed a good idea to split it from the other. I do think it's a good idea because it's just too easy for it to get lost in amongst the old editions.

Those are all relatively minor changes, and the Millennium editions should be combined with the originals.
