- 1.4a ``pyramid.scripting.prepare`` behaved differently than 1.3 series
  function of same name.  In particular, if passed a request, it would not
  set the ``registry`` attribute of the request like 1.3 did.  A symptom
  would be that passing a request to ``pyramid.paster.bootstrap`` (which uses
  the function) that did not have a ``registry`` attribute could assume that
  the registry would be attached to the request by Pyramid.  This assumption
  could be made in 1.3, but not in 1.4.  The assumption can now be made in
  1.4 too (a registry is attached to a request passed to bootstrap or
  prepare).
