the bright side, there's nothing left to take out, so feel free to subclass now. ;-)

--------
- The ``repoze.bfg.url.model_url`` API now works against contexts
derived from Routes URL dispatch (``Routes.util.url_for`` is called
under the hood).
- "Virtual root" support for traversal-based applications has been
added. Virtual root support is useful when you'd like to host some
model in a :mod:`repoze.bfg` model graph as an application under a
URL pathname that does not include the model path itself. For more
information, see the (new) "Virtual Hosting" chapter in the
documentation.
- A ``repoze.bfg.traversal.virtual_root`` API has been added. When
called, it returns the virtual root object (or the physical root
object if no virtual root has been specified).
Implementation Changes
----------------------
- ``repoze.bfg.traversal.RoutesModelTraverser`` has been moved to
``repoze.bfg.urldispatch``.
- ``model_url`` URL generation is now performed via an adapter lookup
based on the context and the request.
- ZCML which registers two adapters for the ``IContextURL`` interface
has been added to the configure.zcml in ``repoze.bfg.includes``.

consults a utility to generate the base model url (without extra
elements or a query string). Eventually this will service virtual
hosting; for now it's undocumented and should not be hooked.

"traversal" API chapter in the docs. This was a function previously
known as ``split_path`` that was not an API but people were using it
anyway. Unlike ``split_path`` it now returns a tuple instead of a
list (as its values are cached).

``wsgiorg.routing_args`` environment variable into the environ when
a route matches. This is a tuple of ((), routing_args) where
routing_args is the value that comes back from the routes mapper
match (the "match dict").
- The ``repoze.bfg.traversal.RoutesModelTraverser`` class now wants to
obtain the ``view_name`` and ``subpath`` from the
``wsgiorgs.routing_args`` environment variable. It falls back to
obtaining these from the context for backwards compatibility.

list of permissions (e.g. ``(Allow, Everyone, ['read', ['view',
['write', 'manage']]])`)`. The list must instead be fully expanded
(e.g. ``(Allow, Everyone, ['read', 'view', 'write', 'manage])``). This
feature was never documented, and was never an API, so it's not a
backwards incompatibility.

``ACLSecurityPolicy`` now does what it did inline.
- Get rid of ``repoze.bfg.interfaces.NoAuthorizationInformation``
exception: it was used only by ``ACLAuthorizer``.

``repoze.bfg.ACLAuthorizer.permits`` (e.g. ['fred', ['larry',
'bob']). The principals list must be fully expanded. This feature
was never documented, and was never an API, so it's not a backwards
incompatibility.

:mod:`repoze.bfg` generates when a view cannot be found or cannot be
invoked due to lack of permission. See the "ZCML Hooks" chapter in
the docs for more information.
- Use a homegrown Unauthorized error instead of
``webob.exc.Unauthorized`` (the latter is slow).
- Various speed micro-tweaks.

----------------
- The ``repoze.bfg.view.render_view_to_response`` API will no longer
raise a ValueError if an object returned by a view function it calls
does not possess certain attributes (``headerlist``, ``app_iter``,
``status``). This API used to attempt to perform a check using the
``is_response`` function in ``repoze.bfg.view``, and raised a
``ValueError`` if the ``is_response`` check failed. The
responsibility is now the caller's to ensure that the return value
from a view function is a "real" response.
- WSGI environ dicts passed to ``repoze.bfg`` 's Router must now
contain a REQUEST_METHOD key/value; if they do not, a KeyError will
be raised (speed).

path segments to unicode (for speed, because its results are
LRU cached).
- ``repoze.bfg.traversal.step`` was made a method of the
ModelGraphTraverser.
|
|
``BFG_UNICODE_PATH_SEGMENTS`` configuration variable have been
removed. Path segments are now always passed to model
``__getitem__`` methods as unicode. "True" has been the default for
this setting since 0.5.4, but changing this configuration setting to
false allowed you to go back to passing raw path element strings to
model ``__getitem__`` methods. This services a speed goal (we get
about +80 req/s by removing the check), and it's clearer just to
always expect unicode path segments in model ``__getitem__``
methods.

lazier about constructing the representation of a reason message for
speed; ``repoze.bfg.view_execution_permitted`` takes advantage of
this.
- The ``is_response`` check was sped up by about half at the expense
of making its code slightly uglier.

``registerSubscriptionAdapter``, ``notify`` is a noop for speed.
