Hi, i'm upgrading from coherence 0.4 to 0.5 and running mix coh.install --reinstall but now i'm getting the following error:

== Compilation error in file lib/twd_web/controllers/coherence/session_controller.ex ==

If you look at the latest session controller you will see that the lines import Coherence.Rememberable, only: [hash: 1, gen_cookie: 3] and alias Coherence.{Rememberable} are commented out. In place of these imported functions, the module now defines these local functions:

defp hash(value) do
  schema(Rememberable).hash value
end

defp gen_cookie(user_id, series, token) do
  schema(Rememberable).gen_cookie user_id, series, token
end

You will need to generate new controllers and use git diff to choose which changes to incorporate.
