Subject: Features --------

- Added a ``traverse`` function to the ``repoze.bfg.traversal``
  module.  This function may be used to retrieve certain values
  computed during path resolution.  See the Traversal API chapter of
  the documentation for more information about this function.

Deprecations
------------

- Internal: ``ITraverser`` callables should now return a dictionary
  rather than a tuple.  Up until 0.7.0, all ITraversers were assumed
  to return a 3-tuple.  In 0.7.1, ITraversers were assumed to return a
  6-tuple.  As (by evidence) it's likely we'll need to add further
  information to the return value of an ITraverser callable, 0.8
  assumes that an ITraverser return a dictionary with certain elements
  in it.  See the ``repoze.bfg.interfaces.ITraverser`` interface for
  the list of keys that should be present in the dictionary.
  ``ITraversers`` which return tuples will still work, although a
  deprecation warning will be issued.

Backwards Incompatibilities
---------------------------

- If your code used the ITraverser interface directly (not via an API
  function such as ``find_model``) via an adapter lookup, you'll need
  to change your code to expect a dictionary rather than a 3- or
  6-tuple if your code ever gets return values from the default
  ModelGraphTraverser or RoutesModelTraverser adapters.
