``repoze.bfg.exceptions.NotFound``. The old location still
functions, but emits a deprecation warning.
- The import of ``repoze.bfg.security.Unauthorized`` is deprecated in
favor of ``repoze.bfg.exceptions.Forbidden``. The old location
still functions but emits a deprecation warning. The rename from
``Unauthorized`` to ``Forbidden`` brings parity to the the name of
the exception and the system view it invokes when raised.
- New ``repoze.bfg.exceptions`` module was created to house exceptions
that were previously sprinkled through various modules.
- An ``exceptions`` API chapter was added, documenting the new
``repoze.bfg.exceptions`` module.

- Speed up ``repoze.bfg.traversal.model_path_tuple`` slightly.
- Speed up ``repoze.bfg.traversal.traverse`` slightly.
- In 0.8a7, the return value expected from an object implementing
``ITraverserFactory`` was changed from a sequence of values to a
dictionary containing the keys ``context``, ``view_name``,
``subpath``, ``traversed``, ``virtual_root``, ``virtual_root_path``,
and ``root``. Until now, old-style traversers which returned a
sequence have continued to work but have generated a deprecation
warning. In this release, traversers which return a sequence
instead of a dictionary will no longer work.

--------
- Speed up ``repoze.bfg.encode.urlencode`` (nee'
``repoze.bfg.url.urlencode``) slightly.
- Speed up ``repoze.bfg.traversal.model_path`` and
``repoze.bfg.traversal.model_path_tuple`` slightly.
Internal
--------
- Move ``repoze.bfg.traversal._url_quote`` into ``repoze.bfg.encode``
as ``url_quote``.
Backwards Incompatibilities
---------------------------
- We previously had a Unicode-aware wrapper for the
``urllib.urlencode`` function named ``repoze.bfg.url.urlencode``
which delegated to the stdlib function, but which marshalled all
unicode values to utf-8 strings before calling the stdlib version.
A newer replacement now lives in ``repoze.bfg.encode`` (old imports
will still work). The replacement does not delegate to the stdlib.
The replacement diverges from the stdlib implementation and the
previous ``repoze.bfg.url`` url implementation inasmuch as its
``doseq`` argument is a decoy: it always behaves in the
``doseq=True`` way (which is the only sane behavior) for speed
purposes.
The old import location (``repoze.bfg.url.urlencode``) still
functions and has not been deprecated.

This should have no external effects.
- An object implementing the ``IRenderer`` interface (and
``ITemplateRenderer`, which is a subclass of ``IRenderer``) must now
accept an extra ``system`` argument in its ``__call__`` method
implementation. Values computed by the system (as opposed to by the
view) are passed by the system in the ``system`` parameter, which
will always be a dictionary. Keys in the dictionary include:
``view`` (the view object that returned the value),
``renderer_name`` (the template name or simple name of the
renderer), ``context`` (the context object passed to the view), and
``request`` (the request object passed to the view). Previously
only ITemplateRenderers received system arguments as elements inside
the main ``value`` dictionary.

- Speed: do not register an IContextURL in configure.zcml; instead
rely on queryAdapter and a manual default to TraversalContextURL.
- General speed microimprovements for helloworld benchmark: replace
try/excepts with statements which use 'in' keyword.

deprecated in favor of
``repoze.bfg.testing.registerTemplateRenderer``. A deprecation
warning is *not* issued at import time for the former name; it will
exist "forever".
- The ``repoze.bfg.templating.renderer_from_cache`` function has been
moved to ``repoze.bfg.renderer.template_renderer_factory``. This
was never an API, but code in the wild was spotted that used it. A
deprecation warning is issued at import time for the former.
- Better error message when a wrapper view returns None.

decorator) can now accept a "wrapper" value. If a "wrapper" value
is supplied, it is the value of a separate view's *name* attribute.
When a view with a ``wrapper`` attribute is rendered, the "inner"
view is first rendered normally. Its body is then attached to the
request as "wrapped_body", and then a wrapper view name is looked up
and rendered (using ``repoze.bfg.render_view_to_response``), passed
the request and the context. The wrapper view is assumed to do
something sensible with ``request.wrapped_body``, usually inserting
its structure into some other rendered template. This feature makes
it possible to specify (potentially nested) "owrap" relationships
between views using only ZCML or decorators (as opposed always using
ZPT METAL and analogues to wrap view renderings in outer wrappers).

decorator) can now accept an "attr" value. If an "attr" value is
supplied, it is considered a method named of the view object to be
called when the response is required. This is typically only good
for views that are classes or instances (not so useful for
functions, as functions typically have no methods other than
``__call__``).
- A ZCML ``view`` directive (and the associated ``bfg_view``
decorator) can now accept a "template" value. If a "template" value
is supplied, and the view callable returns a dictionary, the
associated template is rendered with the dictionary as keyword
arguments.

from "repoze.bfg.registry", deprecated since repoze.bfg 0.9 has been
removed. If you are tring to use the registry manager within a
debug script of your own, use a combination of the
"repoze.bfg.paster.get_app" and "repoze.bfg.scripting.get_root" APIs
instead.

e.g. ``somepackage:foo/bar/static``. This is now the preferred
mechanism for spelling package-relative static paths using this

backwards compatibility. If it is supplied, it will be honored.
