"Rendering a template", API doc missing "2.x"?

The api document for "Rendering a template" at
http://api.rubyonrails.com/classes/ActionController/Base.html#M000452
has:

  # Renders the template located in [TEMPLATE_ROOT]/weblog/show.r(html|
xml) (in Rails, app/views/weblog/show.erb)
  render :template => "weblog/show"

Is it missing 2.x after Rails? Should it be the following?

  # Renders the template located in [TEMPLATE_ROOT]/weblog/show.r(html|
xml) (in Rails 2.x, app/views/weblog/show.erb)
  render :template => "weblog/show"

actually, in Rails 2.x the standard html view would be:
app/views/weblog/show.html.erb
