Module `Html` does not expose `beginnerProgram`
<p>I'm trying to <code>import Html exposing (beginnerProgram)</code>, as it is shown <a href="http://elm-lang.org/examples/buttons" rel="noreferrer">there</a> and <a href="http://package.elm-lang.org/packages/elm-lang/html/2.0.0/Html#beginnerProgram" rel="noreferrer">there</a>, but the compiler doesn't agree : "Module <code>Html</code> does not expose <code>beginnerProgram</code>".</p>

<p>Thanks in advance.</p>
