title: Was partial replacement were removed in Turbolinks 5
body: <p>I am wondering if Turbolinks 5 has partial replacement as in 3rd version.
  Also where is the 3rd version, is it Turbolinks-classic? At the rubygems site I can find only 2.5 and 5th version listed. In turbolinks-classic documentation I see partial replacement documentation which says for versions (3+). So I lost where is the Turbolinks 3, or is it just now called Turbolinks 5? Sorry if my question is unclear. </p>
