The version bump is because 0.5.0 drops support for Clojure 1.3.0.
Release 0.5.0 adds testing against Clojure 1.9.0 master, drops the dependency on core.incubator, and marks the Clojure dependency as “provided” so it’s less likely to cause a conflict downstream.
In addition, :use/:only has been replaced with :require/:refer, and the new-in-Clojure-1.4 reduce-kv is now used in one place. Additional post-1.3 cleanup welcome!
On Clojure 1.9.0 Alpha 5 and later, the built-in seqable? is used instead of the version that core.incubator used to provide (which is copied into congomongo.coerce for the time being).
