--------
- Compatibility with WebOb 1.0.
Requirements
------------
- Now requires WebOb >= 1.0.
Backwards Incompatibilities
---------------------------
- Due to changes introduced WebOb 1.0, the
``repoze.bfg.request.make_request_ascii`` event subscriber no longer
works, so it has been removed. This subscriber was meant to be used
in a deployment so that code written before BFG 0.7.0 could run
unchanged. At this point, such code will need to be rewritten to
expect Unicode from ``request.GET``, ``request.POST`` and
``request.params`` or it will need to be changed to use
``request.str_POST``, ``request.str_GET`` and/or
``request.str_params`` instead of the non-``str`` versions of same,
as the non-``str`` versions of the same APIs always now perform
decoding to Unicode.

``pregenerator`` argument. The pregenerator for the resulting route
is called by ``route_url`` in order to adjust the set of arguments
passed to it by the user for special purposes, such as Pylons
'subdomain' support. It will influence the URL returned by
``route_url``. See the ``repoze.bfg.interfaces.IRoutePregenerator``
interface for more information.

- Rearrange router logic so that start_response is not called until there
is no chance of an exception occurring.
|
|
--------
- A ``request.matched_route`` attribute is now added to the request
when a route has matched. Its value is the "route" object that
matched (see the ``IRoute`` interface within
``repoze.bfg.interfaces`` API documentation for the API of a route
object).
- The ``exception`` attribute of the request is now set slightly
earlier and in a slightly different set of scenarios, for benefit of
"finished callbacks" and "response callbacks". In previous
versions, the ``exception`` attribute of the request was not set at
all if an exception view was not found. In this version, the
``request.exception`` attribute is set immediately when an exception
is caught by the router, even if an exception view could not be
found.
Backwards Incompatibilities
---------------------------
- The router no longer sets the value ``wsgiorg.routing_args`` into
the environ when a route matches. The value used to be something
like ``((), matchdict)``. This functionality was only ever
obliquely referred to in change logs; it was never documented as an
API.
- The ``exception`` attribute of the request now defaults to ``None``.
In prior versions, the ``request.exception`` attribute did not exist
if an exception was not raised by user code during request
processing; it only began existence once an exception view was
found.
Deprecations
------------
- References to the WSGI environment values ``bfg.routes.matchdict``
and ``bfg.routes.route`` were removed from documentation. These
will stick around internally for several more releases, but it is
``request.matchdict`` and ``request.matched_route`` are now the
"official" way to obtain the matchdict and the route object which
resulted in the match.
Documentation
-------------
- Added two sections to the "Hooks" chapter of the documentation:
"Using Response Callbacks" and "Using Finished Callbacks".
- Added documentation of the ``request.exception`` attribute to the
``repoze.bfg.request.Request`` API documentation.
- Added glossary entries for "response callback" and "finished
callback".
- The "Request Processing" narrative chapter has been updated to note
finished and response callback steps.

end of request processing:
``repoze.bfg.interfaces.IFinishedRequest``. This event is meant to
be used when it is necessary to perform unconditional cleanup after
request processing. See the ``repoze.bfg.events.FinishedRequest``
class documentation for more information.
- The ``repoze.bfg.interfaces.IWSGIApplicationCreatedEvent`` event
interface was renamed to
``repoze.bfg.interfaces.IApplicationCreated``. Likewise, the
``repoze.bfg.events.WSGIApplicationCreatedEvent`` class was renamed
to ``repoze.bfg.events.ApplicationCreated``. The older aliases will
continue to work indefinitely.
- The ``repoze.bfg.interfaces.IAfterTraversal`` event interface was
renamed to ``repoze.bfg.interfaces.IContextFound``. Likewise, the
``repoze.bfg.events.AfterTraveral`` class was renamed to
``repoze.bfg.events.ContextFound``. The older aliases will continue
to work indefinitely.

--------
- In support of making it easier to configure applications which are
"secure by default", a default permission feature was added. If
supplied, the default permission is used as the permission string to
all view registrations which don't otherwise name a permission.
These APIs are in support of that:
- A new constructor argument was added to the Configurator:
``default_permission``.
- A new method was added to the Configurator:
``set_default_permission``.
- A new ZCML directive was added: ``default_permission``.
Documentation
-------------
- Added documentation for the ``default_permission`` ZCML directive.
- Added documentation for the ``default_permission`` constructor value
and the ``set_default_permission`` method in the Configurator API
documentation.
- Added a new section to the "security" chapter named "Setting a
Default Permission".
- Document ``renderer_globals_factory`` and ``request_factory``
arguments to Configurator constructor.
