It changed with 2.0.0, which is not that recent ...

The ISBN changes with every major version of R, i.e., it will change
next when 3.0.0 is released. We are already stretching the ISBN rules
to the limit (on the no-change-side) with that policy, and the
reason is exactly to make the reference more stable. But with a major
release we really need to assign a new ISBN.
