- The ``RoutesMapper`` class in ``repoze.bfg.urldispatch`` has been

  removed, as well as its documentation.  It had been deprecated since
  0.6.3.  Code in ``repoze.bfg.urldispatch.RoutesModelTraverser``
  which catered to it has also been removed.

- The semantics of the ``route`` ZCML directive have been simplified.
  Previously, it was assumed that to use a route, you wanted to map a
  route to an externally registered view.  The new ``route`` directive
  instead has a ``view`` attribute which is required, specifying the
  dotted path to a view callable.  When a route directive is
  processed, a view is *registered* using the name attribute of the
  route directive as its name and the callable as its value.  The
  ``view_name`` and ``provides`` attributes of the ``route`` directive
  are therefore no longer used.  Effectively, if you were previously
  using the ``route`` directive, it means you must change a pair of
  ZCML directives that look like this::

    <route
       name="home"
       path=""
       view_name="login"
       factory=".models.root.Root"
     />

    <view
       for=".models.root.Root"
       name="login"
       view=".views.login_view"
     />
    
  To a ZCML directive that looks like this::

    <route
       name="home"
       path=""
       view=".views.login_view"
       factory=".models.root.Root"
     />

  In other words, to make old code work, remove the ``view``
  directives that were only there to serve the purpose of backing
  ``route`` directives, and move their ``view=`` attribute into the
  ``route`` directive itself.

  This change also necessitated that the ``name`` attribute of the
  ``route`` directive is now required.  If you were previously using
  ``route`` directives without a ``name`` attribute, you'll need to
  add one (the name is arbitrary, but must be unique among all
  ``route`` and ``view`` statements).

  The ``provides`` attribute of the ``route`` directive has also been
  removed.  This directive specified a sequence of interface types
  that the generated context would be decorated with.  Since route
  views are always generated now for a single interface
  (``repoze.bfg.IRoutesContext``) as opposed to being looked up
  arbitrarily, there is no need to decorate any context to ensure a
  view is found.

- The Routes ``Route`` object used to resolve the match is now put
  into the environment as ``bfg.route`` when URL dispatch is used.
