- The ``repoze.bfg.urldispatch.Route`` constructor (not an API) now
  accepts a different ordering of arguments.  Previously it was
  ``(pattern, name, factory=None, predicates=())``.  It is now
  ``(name, pattern, factory=None, predicates=())``.  This is in
  support of consistency with ``configurator.add_route``.

- The ``repoze.bfg.urldispatch.RoutesMapper.connect`` method (not an
  API) now accepts a different ordering of arguments.  Previously it
  was ``(pattern, name, factory=None, predicates=())``.  It is now
  ``(name, pattern, factory=None, predicates=())``.  This is in
  support of consistency with ``configurator.add_route``.

- The ``repoze.bfg.urldispatch.RoutesMapper`` object now has a
  ``get_route`` method which returns a single Route object or
  ``None``.

- A new interface ``repoze.bfg.interfaces.IRoute`` was added.  The
  ``repoze.bfg.urldispatch.Route`` object implements this interface.

- The canonical attribute for accessing the routing pattern from a
  route object is now ``pattern`` rather than ``path``.

- The argument to ``repoze.bfg.configuration.Configurator.add_route``
  which was previously called ``path`` is now called ``pattern`` for
  better explicability.  For backwards compatibility purposes, passing
  a keyword argument named ``path`` to ``add_route`` will still work
  indefinitely.

- The ``path`` attribute to the ZCML ``route`` directive is now named
  ``pattern`` for better explicability.  The older ``path`` attribute
  will continue to work indefinitely.

- All narrative, API, and tutorial docs which referred to a route
  pattern as a ``path`` have now been updated to refer to them as a
  ``pattern``.

- The routesalchemy template has been updated to use ``pattern`` in
  its route declarations rather than ``path``.
