I just pushed a commit that allows these two package versions.

The reason is that the last time I touched this package those versions
weren't out, and I made the conservative assumption that changes in
these versions might require changes in my package.

I figure it's no big deal if someone building my examples needs to use a
2-month-old dependency, but frustrating if what's intended as a tutorial
example fails at compile time.
