New Modules

   - A new module ``repoze.bfg.url`` has been added.  It contains the
     ``model_url`` API (moved from ``repoze.bfg.traversal``) and an
     implementation of ``urlencode`` (like Python's
     ``urllib.urlencode``) which can handle Unicode keys and values in
     parameters to the ``query`` argument.

  Deprecations

   - The ``model_url`` function has been moved from
     ``repoze.bfg.traversal`` into ``repoze.bfg.url``.  It can still
     be imported from ``repoze.bfg.traversal`` but an import from
     ``repoze.bfg.traversal`` will emit a DeprecationWarning.

  Features

   - The ``repoze.bfg.url.model_url`` API (nee'
     ``repoze.bfg.traversal.model_url``) now accepts and honors a
     keyword argument named ``query``.  The value of this argument
     will be used to compose a query string, which will be attached to
     the generated URL before it is returned.  See the API docs (in
     the docs directory or `on the web
     <http://static.repoze.org/bfgdocs>`_) for more information.
