Ordering on versions is lexicographic, given multiple versions that satisfy a dependency Cabal will pick the latest.
Just a minor point, but would mind explaining exactly what lexicographic ordering implies? It appears to me that e.g. version 9.3 of a package would be preferred over version 10.0. That strikes me as counter-intuitive.
The lexicographical ordering would make 10.0 > 9.3. In general, A.B > C.D iff A > C or A == C && B > D. When we say the "latest" version we mean "greatest", implying that version numbers increase with time. Does that help? Cheers, Simon
