v1.9.5 2017-11-05

• Fix build with OCaml 4.06 (and -safe-string) (#108 @hcarty)

This means that packages that implicitly depended on the module without including the ocamlfind uri.services package may now fail. Just adding the ocamlfind dependency will fix it, and is backwards compatible with older Uri releases.
