@@ -347,1133 +360,3 @@ Dependencies
 - A dependency on the ``repoze.zcml`` package has been removed (its
   functionality is replaced internally).
 
-1.1.1 (2009-11-21)
-==================
-
-Bug Fixes
----------
-
-- "Hybrid mode" applications (applications which explicitly used
-  traversal *after* url dispatch via ``<route>`` paths containing the
-  ``*traverse`` element) were broken in 1.1-final and all 1.1 alpha
-  and beta releases.  Views registered without a ``route_name`` route
-  shadowed views registered with a ``route_name`` inappropriately.
-
-1.1 (2009-11-15)
-================
-
-Internals
----------
-
-- Remove dead IRouteRequirement interface from ``repoze.bfg.zcml``
-  module.
-
-Documentation
--------------
-
-- Improve the "Extending an Existing Application" narrative chapter.
-
-- Add more sections to the "Defending Design" chapter.
-
-1.1b4 (2009-11-12)
-==================
-
-Bug Fixes
----------
-
-- Use ``alsoProvides`` in the urldispatch module to attach an
-  interface to the request rather than ``directlyProvides`` to avoid
-  disturbing interfaces set in a NewRequest event handler.
-
-Documentation
--------------
-
-- Move 1.0.1 and previous changelog to HISTORY.txt.
-
-- Add examples to ``repoze.bfg.url.model_url`` docstring.
-
-- Add "Defending BFG Design" chapter to frontpage docs.
-
-Templates
----------
-
-- Remove ``ez_setup.py`` and its import from all paster templates,
-  samples, and tutorials for ``distribute`` compatibility.  The
-  documentation already explains how to install virtualenv (which will
-  include some ``setuptools`` package), so these files, imports and
-  usages were superfluous.
-
-Deprecations
-------------
-
-- The ``options`` kw arg to the ``repoze.bfg.router.make_app``
-  function is deprecated.  In its place is the keyword argument
-  ``settings``.  The ``options`` keyword continues to work, and a
-  deprecation warning is not emitted when it is detected.  However,
-  the paster templates, code samples, and documentation now make
-  reference to ``settings`` rather than ``options``.  This
-  change/deprecation was mainly made for purposes of clarity and
-  symmetry with the ``get_settings()`` API and dicussions of
-  "settings" in various places in the docs: we want to use the same
-  name to refer to the same thing everywhere.
-
-1.1b3 (2009-11-06)
-==================
-
-Features
---------
-
-- ``repoze.bfg.testing.registerRoutesMapper`` testing facility added.
-  This testing function registers a routes "mapper" object in the
-  registry, for tests which require its presence.  This function is
-  documented in the ``repoze.bfg.testing`` API documentation.
-
-Bug Fixes
----------
-
-- Compound statements that used an assignment entered into in an
-  interactive IPython session invoked via ``paster bfgshell`` no
-  longer fail to mutate the shell namespace correctly.  For example,
-  this set of statements used to fail::
-
-    In [2]: def bar(x): return x
-      ...:
-    In [3]: list(bar(x) for x in 'abc')
-    Out[3]: NameError: 'bar'
-
-  In this release, the ``bar`` function is found and the correct
-  output is now sent to the console.  Thanks to Daniel Holth for the
-  patch.
-
-- The ``bfgshell`` command did not function properly; it was still
-  expecting to be able to call the root factory with a bare
-  ``environ`` rather than a request object.
-
-Backwards Incompatibilities
----------------------------
-
-- The ``repoze.bfg.scripting.get_root`` function now expects a
-  ``request`` object as its second argument rather than an
-  ``environ``.
-
-1.1b2 (2009-11-02)
-==================
-
-Bug Fixes
----------
-
-- Prevent PyPI installation failure due to ``easy_install`` trying way
-  too hard to guess the best version of Paste.  When ``easy_install``
-  pulls from PyPI it reads links off various pages to determine "more
-  up to date" versions. It incorrectly picks up a link for an ancient
-  version of a package named "Paste-Deploy-0.1" (note the dash) when
-  trying to find the "Paste" distribution and somehow believes it's
-  the latest version of "Paste".  It also somehow "helpfully" decides
-  to check out a version of this package from SVN.  We pin the Paste
-  dependency version to a version greater than 1.7 to work around
-  this ``easy_install`` bug.
-
-Documentation
--------------
-
-- Fix "Hybrid" narrative chapter: stop claiming that ``<view>``
-  statements that mention a route_name need to come afer (in XML
-  order) the ``<route>`` statement which creates the route.  This
-  hasn't been true since 1.1a1.
-
-- "What's New in ``repoze.bfg`` 1.1" document added to narrative
-  documentation.
-
-Features
---------
-
-- Add a new event type: ``repoze.bfg.events.AfterTraversal``.  Events
-  of this type will be sent after traversal is completed, but before
-  any view code is invoked.  Like ``repoze.bfg.events.NewRequest``,
-  This event will have a single attribute: ``request`` representing
-  the current request.  Unlike the request attribute of
-  ``repoze.bfg.events.NewRequest`` however, during an AfterTraversal
-  event, the request object will possess attributes set by the
-  traverser, most notably ``context``, which will be the context used
-  when a view is found and invoked.  The interface
-  ``repoze.bfg.events.IAfterTraversal`` can be used to subscribe to
-  the event.  For example::
-
-    <subscriber for="repoze.bfg.interfaces.IAfterTraversal"
-                handler="my.app.handle_after_traverse"/>
-
-  Like any framework event, a subscriber function should expect one
-  parameter: ``event``.
-
-Dependencies
-------------
-
-- Rather than depending on ``chameleon.core`` and ``chameleon.zpt``
-  distributions individually, depend on Malthe's repackaged
-  ``Chameleon`` distribution (which includes both ``chameleon.core``
-  and ``chameleon.zpt``).
-
-1.1b1 (2009-11-01)
-==================
-
-Bug Fixes
----------
-
-- The routes root factory called route factories and the default route
-  factory with an environ rather than a request.  One of the symptoms
-  of this bug: applications generated using the ``bfg_zodb`` paster
-  template in 1.1a9 did not work properly.
-
-- Reinstate ``renderer`` alias for ``view_renderer`` in the
-  ``<route>`` ZCML directive (in-the-wild 1.1a bw compat).
-
-- ``bfg_routesalchemy`` paster template: change ``<route>``
-  declarations: rename ``renderer`` attribute to ``view_renderer``.
-
-- Header values returned by the ``authtktauthenticationpolicy``
-  ``remember`` and ``forget`` methods would be of type ``unicode``.
-  This violated the WSGI spec, causing a ``TypeError`` to be raised
-  when these headers were used under ``mod_wsgi``.
-
-- If a BFG app that had a route matching the root URL was mounted
-  under a path in modwsgi, ala ``WSGIScriptAlias /myapp
-  /Users/chrism/projects/modwsgi/env/bfg.wsgi``, the home route (a
-  route with the path of ``'/'`` or ``''``) would not match when the
-  path ``/myapp`` was visited (only when the path ``/myapp/`` was
-  visited).  This is now fixed: if the urldispatch root factory notes
-  that the PATH_INFO is empty, it converts it to a single slash before
-  trying to do matching.
-
-Documentation
--------------
-
-- In ``<route>`` declarations in tutorial ZCML, rename ``renderer``
-  attribute to ``view_renderer`` (fwd compat).
-
-- Fix various tutorials broken by 1.1a9 ``<route>`` directive changes.
-
-Internal
---------
-
-- Deal with a potential circref in the traversal module.
-
-1.1a9 (2009-10-31)
-==================
-
-Bug Fixes
----------
-
-- An incorrect ZCML conflict would be encountered when the
-  ``request_param`` predicate attribute was used on the ZCML ``view``
-  directive if any two otherwise same-predicated views had the
-  combination of a predicate value with an ``=`` sign and one without
-  (e.g. ``a`` vs. ``a=123``).
-
-Features
---------
-
-- In previous versions of BFG, the "root factory" (the ``get_root``
-  callable passed to ``make_app`` or a function pointed to by the
-  ``factory`` attribute of a route) was called with a "bare" WSGI
-  environment.  In this version, and going forward, it will be called
-  with a ``request`` object.  The request object passed to the factory
-  implements dictionary-like methods in such a way that existing root
-  factory code which expects to be passed an environ will continue to
-  work.
-
-- The ``__call__`` of a plugin "traverser" implementation (registered
-  as an adapter for ``ITraverser`` or ``ITraverserFactory``) will now
-  receive a *request* as the single argument to its ``__call__``
-  method.  In previous versions it was passed a WSGI ``environ``
-  object.  The request object passed to the factory implements
-  dictionary-like methods in such a way that existing traverser code
-  which expects to be passed an environ will continue to work.
-
-- The ZCML ``route`` directive's attributes ``xhr``,
-  ``request_method``, ``path_info``, ``request_param``, ``header`` and
-  ``accept`` are now *route* predicates rather than *view* predicates.
-  If one or more of these predicates is specified in the route
-  configuration, all of the predicates must return true for the route
-  to match a request.  If one or more of the route predicates
-  associated with a route returns ``False`` when checked during a
-  request, the route match fails, and the next match in the routelist
-  is tried.  This differs from the previous behavior, where no route
-  predicates existed and all predicates were considered view
-  predicates, because in that scenario, the next route was not tried.
-
-Documentation
--------------
-
-- Various changes were made to narrative and API documentation
-  supporting the change from passing a request rather than an environ
-  to root factories and traversers.
-
-Internal
---------
-
-- The request implements dictionary-like methods that mutate and query
-  the WSGI environ.  This is only for the purpose of backwards
-  compatibility with root factories which expect an ``environ`` rather
-  than a request.
-
-- The ``repoze.bfg.request.create_route_request_factory`` function,
-  which returned a request factory was removed in favor of a
-  ``repoze.bfg.request.route_request_interface`` function, which
-  returns an interface.
-
-- The ``repoze.bfg.request.Request`` class, which is a subclass of
-  ``webob.Request`` now defines its own ``__setattr__``,
-  ``__getattr__`` and ``__delattr__`` methods, which override the
-  default WebOb behavior.  The default WebOb behavior stores
-  attributes of the request in ``self.environ['webob.adhoc_attrs']``,
-  and retrieves them from that dictionary during a ``__getattr__``.
-  This behavior was undesirable for speed and "expectation" reasons.
-  Now attributes of the ``request`` are stored in ``request.__dict__``
-  (as you otherwise might expect from an object that did not override
-  these methods).
-
-- The router no longer calls ``repoze.bfg.traversal._traverse`` and
-  does its work "inline" (speed).
-
-- Reverse the order in which the router calls the request factory and
-  the root factory.  The request factory is now called first; the
-  resulting request is passed to the root factory.
-
-- The ``repoze.bfg.request.request_factory`` function has been
-  removed.  Its functionality is no longer required.
-
-- The "routes root factory" that wraps the default root factory when
-  there are routes mentioned in the configuration now attaches an
-  interface to the request via ``zope.interface.directlyProvides``.
-  This replaces logic in the (now-gone)
-  ``repoze.bfg.request.request_factory`` function.
-
-- The ``route`` and ``view`` ZCML directives now register an interface
-  as a named utility (retrieved from
-  ``repoze.bfg.request.route_request_interface``) rather than a
-  request factory (the previous return value of the now-missing 
-  ``repoze.bfg.request.create_route_request_factory``.
-
-- The ``repoze.bfg.functional`` module was renamed to
-  ``repoze.bfg.compat``.
-
-Backwards Incompatibilities
----------------------------
-
-- Explicitly revert the feature introduced in 1.1a8: where the name
-  ``root`` is available as an attribute of the request before a
-  NewRequest event is emitted.  This makes some potential future
-  features impossible, or at least awkward (such as grouping traversal
-  and view lookup into a single adapter lookup).
-
-- The ``containment``, ``attr`` and ``renderer`` attributes of the
-  ``route`` ZCML directive were removed.
-
-1.1a8 (2009-10-27)
-==================
-
-Features
---------
-
-- Add ``path_info`` view configuration predicate.
-
-- ``paster bfgshell`` now supports IPython if it's available for
-  import.  Thanks to Daniel Holth for the initial patch.
-
-- Add ``repoze.bfg.testing.registerSettings`` API, which is documented
-  in the "repoze.bfg.testing" API chapter.  This allows for
-  registration of "settings" values obtained via
-  ``repoze.bfg.settings.get_settings()`` for use in unit tests.
-
-- The name ``root`` is available as an attribute of the request
-  slightly earlier now (before a NewRequest event is emitted).
-  ``root`` is the result of the application "root factory".
-
-- Added ``max_age`` parameter to ``authtktauthenticationpolicy`` ZCML
-  directive.  If this value is set, it must be an integer representing
-  the number of seconds which the auth tkt cookie will survive.
-  Mainly, its existence allows the auth_tkt cookie to survive across
-  browser sessions.
-
-Bug Fixes
----------
-
-- Fix bug encountered during "scan" (when ``<scan ..>`` directive is
-  used in ZCML) introduced in 1.1a7.  Symptom: ``AttributeError:
-  object has no attribute __provides__`` raised at startup time.
-
-- The ``reissue_time`` argument to the ``authtktauthenticationpolicy``
-  ZCML directive now actually works.  When it is set to an integer
-  value, an authticket set-cookie header is appended to the response
-  whenever a request requires authentication and 'now' minus the
-  authticket's timestamp is greater than ``reissue_time`` seconds.
-
-Documentation
--------------
-
-- Add a chapter titled "Request and Response" to the narrative
-  documentation, content cribbed from the WebOb documentation.
-
-- Call out predicate attributes of ZCML directive within "Views"
-  chapter.
-
-- Fix route_url documentation (``_query`` argument documented as
-  ``query`` and ``_anchor`` argument documented as ``anchor``).
-
-Backwards Incompatibilities
----------------------------
-
-- The ``authtkt`` authentication policy ``remember`` method now no
-  longer honors ``token`` or ``userdata`` keyword arguments.
-
-Internal
---------
-
-- Change how ``bfg_view`` decorator works when used as a class method
-  decorator.  In 1.1a7, the``scan``directive actually tried to grope
-  every class in scanned package at startup time, calling ``dir``
-  against each found class, and subsequently invoking ``getattr``
-  against each thing found by ``dir`` to see if it was a method.  This
-  led to some strange symptoms (e.g. ``AttributeError: object has no
-  attribute __provides__``), and was generally just a bad idea.  Now,
-  instead of groping classes for methods at startup time, we just
-  cause the ``bfg_view`` decorator itself to populate the method's
-  class' ``__dict__`` when it is used as a method decorator.  This
-  also requires a nasty _getframe thing but it's slightly less nasty
-  than the startup time groping behavior.  This is essentially a
-  reversion back to 1.1a6 "grokking" behavior plus some special magic
-  for using the ``bfg_view`` decorator as method decorator inside the
-  ``bfg_view`` class itself.
-
-- The router now checks for a ``global_response_headers`` attribute of
-  the request object before returning a response.  If this value
-  exists, it is presumed to be a sequence of two-tuples, representing
-  a set of headers to append to the 'normal' response headers.  This
-  feature is internal, rather than exposed externally, because it's
-  unclear whether it will stay around in the long term.  It was added
-  to support the ``reissue_time`` feature of the authtkt
-  authentication policy.
-
-- The interface ITraverserFactory is now just an alias for ITraverser.
-
-1.1a7 (2009-10-18)
-==================
-
-Features
---------
-
-- More than one ``@bfg_view`` decorator may now be stacked on top of
-  any number of others.  Each invocation of the decorator registers a
-  single view configuration.  For instance, the following combination
-  of decorators and a function will register two view configurations
-  for the same view callable::
-
-    from repoze.bfg.view import bfg_view
-
-    @bfg_view(name='edit')
-    @bfg_view(name='change')
-    def edit(context, request):
-        pass
-
-  This makes it possible to associate more than one view configuration
-  with a single callable without requiring any ZCML.
-
-- The ``@bfg_view`` decorator can now be used against a class method::
-
-    from webob import Response
-    from repoze.bfg.view import bfg_view
-
-    class MyView(object):
-        def __init__(self, context, request):
-            self.context = context
-            self.request = request
-
-        @bfg_view(name='hello')
-        def amethod(self):
-            return Response('hello from %s!' % self.context)
-
-  When the bfg_view decorator is used against a class method, a view
-  is registered for the *class* (it's a "class view" where the "attr"
-  happens to be the name of the method it is attached to), so the
-  class it's defined within must have a suitable constructor: one that
-  accepts ``context, request`` or just ``request``.
-
-Documentation
--------------
-
-- Added ``Changing the Traverser`` and ``Changing How
-  :mod:`repoze.bfg.url.model_url` Generates a URL`` to the "Hooks"
-  narrative chapter of the docs.
-
-Internal
---------
-
-- Remove ``ez_setup.py`` and imports of it within ``setup.py``.  In
-  the new world, and as per virtualenv setup instructions, people will
-  already have either setuptools or distribute.
-
-1.1a6 (2009-10-15)
-==================
-
-Features
---------
-
-- Add ``xhr``, ``accept``, and ``header`` view configuration
-  predicates to ZCML view declaration, ZCML route declaration, and
-  ``bfg_view`` decorator.  See the ``Views`` narrative documentation
-  chapter for more information about these predicates.
-
-- Add ``setUp`` and ``tearDown`` functions to the
-  ``repoze.bfg.testing`` module.  Using ``setUp`` in a test setup and
-  ``tearDown`` in a test teardown is now the recommended way to do
-  component registry setup and teardown.  Previously, it was
-  recommended that a single function named
-  ``repoze.bfg.testing.cleanUp`` be called in both the test setup and
-  tear down.  ``repoze.bfg.testing.cleanUp`` still exists (and will
-  exist "forever" due to its widespread use); it is now just an alias
-  for ``repoze.bfg.testing.setUp`` and is nominally deprecated.
-
-- The BFG component registry is now available in view and event
-  subscriber code as an attribute of the request
-  ie. ``request.registry``.  This fact is currently undocumented
-  except for this note, because BFG developers never need to interact
-  with the registry directly anywhere else.
-
-- The BFG component registry now inherits from ``dict``, meaning that
-  it can optionally be used as a simple dictionary.  *Component*
-  registrations performed against it via e.g. ``registerUtility``,
-  ``registerAdapter``, and similar API methods are kept in a
-  completely separate namespace than its dict members, so using the
-  its component API methods won't effect the keys and values in the
-  dictionary namespace.  Likewise, though the component registry
-  "happens to be" a dictionary, use of mutating dictionary methods
-  such as ``__setitem__`` will have no influence on any component
-  registrations made against it.  In other words, the registry object
-  you obtain via e.g. ``repoze.bfg.threadlocal.get_current_registry``
-  or ``request.registry`` happens to be both a component registry and
-  a dictionary, but using its component-registry API won't impact data
-  added to it via its dictionary API and vice versa.  This is a
-  forward compatibility move based on the goals of "marco".
-
-- Expose and document ``repoze.bfg.testing.zcml_configure`` API.  This
-  function populates a component registry from a ZCML file for testing
-  purposes.  It is documented in the "Unit and Integration Testing"
-  chapter.
-
-Documentation
--------------
-
-- Virtual hosting narrative docs chapter updated with info about
-  ``mod_wsgi``.
-
-- Point all index URLs at the literal 1.1 index (this alpha cycle may
-  go on a while).
-
-- Various tutorial test modules updated to use
-  ``repoze.bfg.testing.setUp`` and ``repoze.bfg.testing.tearDown``
-  methods in order to encourage this as best practice going forward.
-
-- Added "Creating Integration Tests" section to unit testing narrative
-  documentation chapter.  As a result, the name of the unittesting
-  chapter is now "Unit and Integration Testing".
-
-Backwards Incompatibilities
----------------------------
-
-- Importing ``getSiteManager`` and ``get_registry`` from
-  ``repoze.bfg.registry`` is no longer supported.  These imports were
-  deprecated in repoze.bfg 1.0.  Import of ``getSiteManager`` should
-  be done as ``from zope.component import getSiteManager``.  Import of
-  ``get_registry`` should be done as ``from repoze.bfg.threadlocal
-  import get_current_registry``.  This was done to prevent a circular
-  import dependency.
-
-- Code bases which alternately invoke both
-  ``zope.testing.cleanup.cleanUp`` and ``repoze.bfg.testing.cleanUp``
-  (treating them equivalently, using them interchangeably) in the
-  setUp/tearDown of unit tests will begin to experience test failures
-  due to lack of test isolation.  The "right" mechanism is
-  ``repoze.bfg.testing.cleanUp`` (or the combination of
-  ``repoze.bfg.testing.setUp`` and
-  ``repoze.bfg.testing.tearDown``). but a good number of legacy
-  codebases will use ``zope.testing.cleanup.cleanUp`` instead.  We
-  support ``zope.testing.cleanup.cleanUp`` but not in combination with
-  ``repoze.bfg.testing.cleanUp`` in the same codebase.  You should use
-  one or the other test cleanup function in a single codebase, but not
-  both.
-
-Internal
---------
-
-- Created new ``repoze.bfg.configuration`` module which assumes
-  responsibilities previously held by the ``repoze.bfg.registry`` and
-  ``repoze.bfg.router`` modules (avoid a circular import dependency).
-
-- The result of the ``zope.component.getSiteManager`` function in unit
-  tests set up with ``repoze.bfg.testing.cleanUp`` or
-  ``repoze.bfg.testing.setUp`` will be an instance of
-  ``repoze.bfg.registry.Registry`` instead of the global
-  ``zope.component.globalregistry.base`` registry.  This also means
-  that the threadlocal ZCA API functions such as ``getAdapter`` and
-  ``getUtility`` as well as internal BFG machinery (such as
-  ``model_url`` and ``route_url``) will consult this registry within
-  unit tests. This is a forward compatibility move based on the goals
-  of "marco".
-
-- Removed ``repoze.bfg.testing.addCleanUp`` function and associated
-  module-scope globals.  This was never an API.
-
-1.1a5 (2009-10-10)
-==================
-
-Documentation
--------------
-
-- Change "Traversal + ZODB" and "URL Dispatch + SQLAlchemy" Wiki
-  tutorials to make use of the new-to-1.1 "renderer" feature (return
-  dictionaries from all views).
-
-- Add tests to the "URL Dispatch + SQLAlchemy" tutorial after the
-  "view" step.
-
-- Added a diagram of model graph traversal to the "Traversal"
-  narrative chapter of the documentation.
-
-- An ``exceptions`` API chapter was added, documenting the new
-  ``repoze.bfg.exceptions`` module.
-
-- Describe "request-only" view calling conventions inside the
-  urldispatch narrative chapter, where it's most helpful.
-
-- Add a diagram which explains the operation of the BFG router to the
-  "Router" narrative chapter.
-
-Features
---------
-
-- Add a new ``repoze.bfg.testing`` API: ``registerRoute``, for
-  registering routes to satisfy calls to
-  e.g. ``repoze.bfg.url.route_url`` in unit tests.
-
-- The ``notfound`` and ``forbidden`` ZCML directives now accept the
-  following addtional attributes: ``attr``, ``renderer``, and
-  ``wrapper``.  These have the same meaning as they do in the context
-  of a ZCML ``view`` directive.
-
-- For behavior like Django's ``APPEND_SLASH=True``, use the
-  ``repoze.bfg.view.append_slash_notfound_view`` view as the Not Found
-  view in your application.  When this view is the Not Found view
-  (indicating that no view was found), and any routes have been
-  defined in the configuration of your application, if the value of
-  ``PATH_INFO`` does not already end in a slash, and if the value of
-  ``PATH_INFO`` *plus* a slash matches any route's path, do an HTTP
-  redirect to the slash-appended PATH_INFO.  Note that this will
-  *lose* ``POST`` data information (turning it into a GET), so you
-  shouldn't rely on this to redirect POST requests.
-
-- Speed up ``repoze.bfg.location.lineage`` slightly.
-
-- Speed up ``repoze.bfg.encode.urlencode`` (nee'
-  ``repoze.bfg.url.urlencode``) slightly.
-
-- Speed up ``repoze.bfg.traversal.model_path``.
-
-- Speed up ``repoze.bfg.traversal.model_path_tuple`` slightly.
-
-- Speed up ``repoze.bfg.traversal.traverse`` slightly.
-
-- Speed up ``repoze.bfg.url.model_url`` slightly.
-
-- Speed up ``repoze.bfg.url.route_url`` slightly.
-
-- Sped up ``repoze.bfg.traversal.ModelGraphTraverser:__call__``
-  slightly.
-
-- Minor speedup of ``repoze.bfg.router.Router.__call__``.
-
-- New ``repoze.bfg.exceptions`` module was created to house exceptions
-  that were previously sprinkled through various modules.
-
-Internal
---------
-
-- Move ``repoze.bfg.traversal._url_quote`` into ``repoze.bfg.encode``
-  as ``url_quote``.
-
-Deprecations
-------------
-
-- The import of ``repoze.bfg.view.NotFound`` is deprecated in favor of
-  ``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.
-
-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`` 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 now 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.
-
-- 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.
-
-1.1a4 (2009-09-23)
-==================
-
-Bug Fixes
----------
-
-- On 64-bit Linux systems, views that were members of a multiview
-  (orderings of views with predicates) were not evaluated in the
-  proper order.  Symptom: in a configuration that had two views with
-  the same name but one with a ``request_method=POST`` predicate and
-  one without, the one without the predicate would be called
-  unconditionally (even if the request was a POST request).  Thanks
-  much to Sebastien Douche for providing the buildbots that pointed
-  this out.
-
-Documentation
--------------
-
-- Added a tutorial which explains how to use ``repoze.session``
-  (ZODB-based sessions) in a ZODB-based repoze.bfg app.
-
-- Added a tutorial which explains how to add ZEO to a ZODB-based
-  ``repoze.bfg`` application.
-
-- Added a tutorial which explains how to run a ``repoze.bfg``
-  application under `mod_wsgi <http://code.google.com/p/modwsgi/>`_.
-  See "Running a repoze.bfg Application under mod_wsgi" in the
-  tutorials section of the documentation.
-
-Features
---------
-
-- Add a ``repoze.bfg.url.static_url`` API which is capable of
-  generating URLs to static resources defined by the ``<static>`` ZCML
-  directive.  See the "Views" narrative chapter's section titled
-  "Generating Static Resource URLs" for more information.
-
-- Add a ``string`` renderer.  This renderer converts a non-Response
-  return value of any view callble into a string.  It is documented in
-  the "Views" narrative chapter.
-
-- Give the ``route`` ZCML directive the ``view_attr`` and
-  ``view_renderer`` parameters (bring up to speed with 1.1a3
-  features).  These can also be spelled as ``attr`` and ``renderer``.
-
-Backwards Incompatibilities
----------------------------
-
-- 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.
-
-Internal
---------
-
-- The way ``bfg_view`` declarations are scanned for has been modified.
-  This should have no external effects.
-
-- Speed: do not register an ITraverserFactory in configure.zcml;
-  instead rely on queryAdapter and a manual default to
-  ModelGraphTraverser.
-
-- 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.
-
-1.1a3 (2009-09-16)
-==================
-
-Documentation
--------------
-
-- The "Views" narrative chapter in the documentation has been updated
-  extensively to discuss "renderers".
-
-Features
---------
-
-- A ``renderer`` attribute has been added to view configurations,
-  replacing the previous (1.1a2) version's ``template`` attribute.  A
-  "renderer" is an object which accepts the return value of a view and
-  converts it to a string.  This includes, but is not limited to,
-  templating systems.
-
-- A new interface named ``IRenderer`` was added.  The existing
-  interface, ``ITemplateRenderer`` now derives from this new
-  interface.  This interface is internal.
-
-- A new interface named ``IRendererFactory`` was added.  An existing
-  interface named ``ITemplateRendererFactory`` now derives from this
-  interface.  This interface is internal.
-
-- The ``view`` attribute of the ``view`` ZCML directive is no longer
-  required if the ZCML directive also has a ``renderer`` attribute.
-  This is useful when the renderer is a template renderer and no names
-  need be passed to the template at render time.
-
-- A new zcml directive ``renderer`` has been added.  It is documented
-  in the "Views" narrative chapter of the documentation.
-
-- A ZCML ``view`` directive (and the associated ``bfg_view``
-  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).
-
-Dependencies
-------------
-
-- When used under Python < 2.6, BFG now has an installation time
-  dependency on the ``simplejson`` package.
-
-Deprecations
-------------
-
-- The ``repoze.bfg.testing.registerDummyRenderer`` API has been
-  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"; its existence has been removed from the
-  documentation, however.
-
-- 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.
-
-Backwards Incompatibilities
----------------------------
-
-- The ``ITemplateRenderer`` interface has been changed.  Previously
-  its ``__call__`` method accepted ``**kw``.  It now accepts a single
-  positional parameter named ``kw`` (REVISED: it accepts two
-  positional parameters as of 1.1a4: ``value`` and ``system``).  This
-  is mostly an internal change, but it was exposed in APIs in one
-  place: if you've used the
-  ``repoze.bfg.testing.registerDummyRenderer`` API in your tests with
-  a custom "renderer" argument with your own renderer implementation,
-  you will need to change that renderer implementation to accept
-  ``kw`` instead of ``**kw`` in its ``__call__`` method (REVISED: make
-  it accept ``value`` and ``system`` positional arguments as of 1.1a4).
-
-- The ``ITemplateRendererFactory`` interface has been changed.
-  Previously its ``__call__`` method accepted an ``auto_reload``
-  keyword parameter.  Now its ``__call__`` method accepts no keyword
-  parameters.  Renderers are now themselves responsible for
-  determining details of auto-reload.  This is purely an internal
-  change.  This interface was never external.
-
-- The ``template_renderer`` ZCML directive introduced in 1.1a2 has
-  been removed.  It has been replaced by the ``renderer`` directive.
-
-- The previous release (1.1a2) added a view configuration attribute
-  named ``template``.  In this release, the attribute has been renamed
-  to ``renderer``.  This signifies that the attribute is more generic:
-  it can now be not just a template name but any renderer name (ala
-  ``json``).  
-
-- In the previous release (1.1a2), the Chameleon text template
-  renderer was used if the system didn't associate the ``template``
-  view configuration value with a filename with a "known" extension.
-  In this release, you must use a ``renderer`` attribute which is a
-  path that ends with a ``.txt`` extension
-  (e.g. ``templates/foo.txt``) to use the Chameleon text renderer.
-
-1.1a2 (2009-09-14)
-==================
-
-Features
---------
-
-- A ZCML ``view`` directive (and the associated ``bfg_view``
-  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.  See the section named "Views That Have a ``template``"
-  in the "Views" narrative documentation chapter for more information.
-
-1.1a1 (2009-09-06)
-==================
-
-Bug Fixes
----------
-
-- "tests" module removed from the bfg_alchemy paster template; these
-  tests didn't work.
-
-- Bugfix: the ``discriminator`` for the ZCML "route" directive was
-  incorrect.  It was possible to register two routes that collided
-  without the system spitting out a ConfigurationConflictError at
-  startup time.
-
-Features
---------
-
-- Feature addition: view predicates.  These are exposed as the
-  ``request_method``, ``request_param``, and ``containment``
-  attributes of a ZCML ``view`` declaration, or the respective
-  arguments to a ``@bfg_view`` decorator.  View predicates can be used
-  to register a view for a more precise set of environment parameters
-  than was previously possible.  For example, you can register two
-  views with the same ``name`` with different ``request_param``
-  attributes.  If the ``request.params`` dict contains 'foo'
-  (request_param="foo"), one view might be called; if it contains
-  'bar' (request_param="bar"), another view might be called.
-  ``request_param`` can also name a key/value pair ala ``foo=123``.
-  This will match only when the ``foo`` key is in the request.params
-  dict and it has the value '123'.  This particular example makes it
-  possible to write separate view functions for different form
-  submissions.  The other predicates, ``containment`` and
-  ``request_method`` work similarly.  ``containment`` is a view
-  predicate that will match only when the context's graph lineage has
-  an object possessing a particular class or interface, for example.
-  ``request_method`` is a view predicate that will match when the HTTP
-  ``REQUEST_METHOD`` equals some string (eg. 'POST').
-
-- The ``@bfg_view`` decorator now accepts three additional arguments:
-  ``request_method``, ``request_param``, and ``containment``.
-  ``request_method`` is used when you'd like the view to match only a
-  request with a particular HTTP ``REQUEST_METHOD``; a string naming
-  the ``REQUEST_METHOD`` can also be supplied as ``request_type`` for
-  backwards compatibility.  ``request_param`` is used when you'd like
-  a view to match only a request that contains a particular
-  ``request.params`` key (with or without a value).  ``containment``
-  is used when you'd like to match a request that has a context that
-  has some class or interface in its graph lineage.  These are
-  collectively known as "view predicates".
-
-- The ``route`` ZCML directive now honors ``view_request_method``,
-  ``view_request_param`` and ``view_containment`` attributes, which
-  pass along these values to the associated view if any is provided.
-  Additionally, the ``request_type`` attribute can now be spelled as
-  ``view_request_type``, and ``permission`` can be spelled as
-  ``view_permission``.  Any attribute which starts with ``view_`` can
-  now be spelled without the ``view_`` prefix, so ``view_for`` can be
-  spelled as ``for`` now, etc.  Both forms are documented in the
-  urldispatch narraitve documentation chapter.
-
-- The ``request_param`` ZCML view directive attribute (and its
-  ``bfg_view`` decorator cousin) can now specify both a key and a
-  value.  For example, ``request_param="foo=123"`` means that the foo
-  key must have a value of ``123`` for the view to "match".
-
-- Allow ``repoze.bfg.traversal.find_interface`` API to use a class
-  object as the argument to compare against the ``model`` passed in.
-  This means you can now do ``find_interface(model, SomeClass)`` and
-  the first object which is found in the lineage which has
-  ``SomeClass`` as its class (or the first object found which has
-  ``SomeClass`` as any of its superclasses) will be returned.
-
-- Added ``static`` ZCML directive which registers a route for a view
-  that serves up files in a directory.  See the "Views" narrative
-  documentation chapter's "Serving Static Resources Using a ZCML
-  Directive" section for more information.
-
-- The ``repoze.bfg.view.static`` class now accepts a string as its
-  first argument ("root_dir") that represents a package-relative name
-  e.g. ``somepackage:foo/bar/static``.  This is now the preferred
-  mechanism for spelling package-relative static paths using this
-  class.  A ``package_name`` keyword argument has been left around for
-  backwards compatibility.  If it is supplied, it will be honored.
-
-- The API ``repoze.bfg.testing.registerView`` now takes a
-  ``permission`` argument.  Use this instead of using
-  ``repoze.bfg.testing.registerViewPermission``.
-
-- The ordering of route declarations vs. the ordering of view
-  declarations that use a "route_name" in ZCML no longer matters.
-  Previously it had been impossible to use a route_name from a route
-  that had not yet been defined in ZCML (order-wise) within a "view"
-  declaration.
-
-- The repoze.bfg router now catches both
-  ``repoze.bfg.security.Unauthorized`` and
-  ``repoze.bfg.view.NotFound`` exceptions while rendering a view.
-  When the router catches an ``Unauthorized``, it returns the
-  registered forbidden view.  When the router catches a ``NotFound``,
-  it returns the registered notfound view.
-
-Internal
---------
-
-- Change urldispatch internals: Route object is now constructed using
-  a path, a name, and a factory instead of a name, a matcher, a
-  generator, and a factory.
-
-- Move (non-API) default_view, default_forbidden_view, and
-  default_notfound_view functions into the ``repoze.bfg.view`` module
-  (moved from ``repoze.bfg.router``).
-
-- Removed ViewPermissionFactory from ``repoze.bfg.security``.  View
-  permission checking is now done by registering and looking up an
-  ISecuredView.
-
-- The ``static`` ZCML directive now uses a custom root factory when
-  constructing a route.
-
-- The interface ``IRequestFactories`` was removed from the
-  repoze.bfg.interfaces module.  This interface was never an API.
-
-- The function named ``named_request_factories`` and the data
-  structure named ``DEFAULT_REQUEST_FACTORIES`` have been removed from
-  the ``repoze.bfg.request`` module.  These were never APIs.
-
-- The ``IViewPermissionFactory`` interface has been removed.  This was
-  never an API.
-
-Documentation
--------------
-
-- Request-only-convention examples in the "Views" narrative
-  documentation were broken.
-
-- Fixed documentation bugs related to forget and remember in security API
-  docs.
-
-- Fixed documentation for ``repoze.bfg.view.static`` (in narrative
-  ``Views`` chapter).
-
-Deprecations
-------------
-
-- The API ``repoze.bfg.testing.registerViewPermission`` has been
-  deprecated.
-
-Backwards Incompatibilities
----------------------------
-
-- The interfaces ``IPOSTRequest``, ``IGETRequest``, ``IPUTRequest``,
-  ``IDELETERequest``, and ``IHEADRequest`` have been removed from the
-  ``repoze.bfg.interfaces`` module.  These were not documented as APIs
-  post-1.0.  Instead of using one of these, use a ``request_method``
-  ZCML attribute or ``request_method`` bfg_view decorator parameter
-  containing an HTTP method name (one of ``GET``, ``POST``, ``HEAD``,
-  ``PUT``, ``DELETE``) instead of one of these interfaces if you were
-  using one explicitly.  Passing a string in the set (``GET``,
-  ``HEAD``, ``PUT``, ``POST``, ``DELETE``) as a ``request_type``
-  argument will work too.  Rationale: instead of relying on interfaces
-  attached to the request object, BFG now uses a "view predicate" to
-  determine the request type.
-
-- Views registered without the help of the ZCML ``view`` directive are
-  now responsible for performing their own authorization checking.
-
-- The ``registry_manager`` backwards compatibility alias importable
-  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.
-
-- The ``INotFoundAppFactory`` interface has been removed; it has
-  been deprecated since repoze.bfg 0.9.  If you have something like
-  the following in your ``configure.zcml``::
-
-   <utility provides="repoze.bfg.interfaces.INotFoundAppFactory"
-            component="helloworld.factories.notfound_app_factory"/>
-
-  Replace it with something like::
-
-   <notfound 
-       view="helloworld.views.notfound_view"/>
-
-  See "Changing the Not Found View" in the "Hooks" chapter of the
-  documentation for more information.
-
-- The ``IUnauthorizedAppFactory`` interface has been removed; it has
-  been deprecated since repoze.bfg 0.9.  If you have something like
-  the following in your ``configure.zcml``::
-
-   <utility provides="repoze.bfg.interfaces.IUnauthorizedAppFactory"
-            component="helloworld.factories.unauthorized_app_factory"/>
-
-  Replace it with something like::
-
-   <forbidden
-       view="helloworld.views.forbidden_view"/>
-
-  See "Changing the Forbidden View" in the "Hooks" chapter of the
-  documentation for more information.
-
-- ``ISecurityPolicy``-based security policies, deprecated since
-  repoze.bfg 0.9, have been removed.  If you have something like this
-  in your ``configure.zcml``, it will no longer work::
-
-     <utility
-       provides="repoze.bfg.interfaces.ISecurityPolicy"
-       factory="repoze.bfg.security.RemoteUserInheritingACLSecurityPolicy"
-      />
-
-  If ZCML like the above exists in your application, you will receive
-  an error at startup time.  Instead of the above, you'll need
-  something like::
-
-     <remoteuserauthenticationpolicy/>
-     <aclauthorizationpolicy/>
-
-  This is just an example.  See the "Security" chapter of the
-  repoze.bfg documentation for more information about configuring
-  security policies.
-
-- Custom ZCML directives which register an authentication or
-  authorization policy (ala "authtktauthenticationpolicy" or
-  "aclauthorizationpolicy") should register the policy "eagerly" in
-  the ZCML directive instead of from within a ZCML action.  If an
-  authentication or authorization policy is not found in the component
-  registry by the view machinery during deferred ZCML processing, view
-  security will not work as expected.

+1.1.1 (2009-11-21)
+==================
+
+Bug Fixes
+---------
+
+- "Hybrid mode" applications (applications which explicitly used
+  traversal *after* url dispatch via ``<route>`` paths containing the
+  ``*traverse`` element) were broken in 1.1-final and all 1.1 alpha
+  and beta releases.  Views registered without a ``route_name`` route
+  shadowed views registered with a ``route_name`` inappropriately.
+
+1.1 (2009-11-15)
+================
+
+Internals
+---------
+
+- Remove dead IRouteRequirement interface from ``repoze.bfg.zcml``
+  module.
+
+Documentation
+-------------
+
+- Improve the "Extending an Existing Application" narrative chapter.
+
+- Add more sections to the "Defending Design" chapter.
+
+1.1b4 (2009-11-12)
+==================
+
+Bug Fixes
+---------
+
+- Use ``alsoProvides`` in the urldispatch module to attach an
+  interface to the request rather than ``directlyProvides`` to avoid
+  disturbing interfaces set in a NewRequest event handler.
+
+Documentation
+-------------
+
+- Move 1.0.1 and previous changelog to HISTORY.txt.
+
+- Add examples to ``repoze.bfg.url.model_url`` docstring.
+
+- Add "Defending BFG Design" chapter to frontpage docs.
+
+Templates
+---------
+
+- Remove ``ez_setup.py`` and its import from all paster templates,
+  samples, and tutorials for ``distribute`` compatibility.  The
+  documentation already explains how to install virtualenv (which will
+  include some ``setuptools`` package), so these files, imports and
+  usages were superfluous.
+
+Deprecations
+------------
+
+- The ``options`` kw arg to the ``repoze.bfg.router.make_app``
+  function is deprecated.  In its place is the keyword argument
+  ``settings``.  The ``options`` keyword continues to work, and a
+  deprecation warning is not emitted when it is detected.  However,
+  the paster templates, code samples, and documentation now make
+  reference to ``settings`` rather than ``options``.  This
+  change/deprecation was mainly made for purposes of clarity and
+  symmetry with the ``get_settings()`` API and dicussions of
+  "settings" in various places in the docs: we want to use the same
+  name to refer to the same thing everywhere.
+
+1.1b3 (2009-11-06)
+==================
+
+Features
+--------
+
+- ``repoze.bfg.testing.registerRoutesMapper`` testing facility added.
+  This testing function registers a routes "mapper" object in the
+  registry, for tests which require its presence.  This function is
+  documented in the ``repoze.bfg.testing`` API documentation.
+
+Bug Fixes
+---------
+
+- Compound statements that used an assignment entered into in an
+  interactive IPython session invoked via ``paster bfgshell`` no
+  longer fail to mutate the shell namespace correctly.  For example,
+  this set of statements used to fail::
+
+    In [2]: def bar(x): return x
+      ...:
+    In [3]: list(bar(x) for x in 'abc')
+    Out[3]: NameError: 'bar'
+
+  In this release, the ``bar`` function is found and the correct
+  output is now sent to the console.  Thanks to Daniel Holth for the
+  patch.
+
+- The ``bfgshell`` command did not function properly; it was still
+  expecting to be able to call the root factory with a bare
+  ``environ`` rather than a request object.
+
+Backwards Incompatibilities
+---------------------------
+
+- The ``repoze.bfg.scripting.get_root`` function now expects a
+  ``request`` object as its second argument rather than an
+  ``environ``.
+
+1.1b2 (2009-11-02)
+==================
+
+Bug Fixes
+---------
+
+- Prevent PyPI installation failure due to ``easy_install`` trying way
+  too hard to guess the best version of Paste.  When ``easy_install``
+  pulls from PyPI it reads links off various pages to determine "more
+  up to date" versions. It incorrectly picks up a link for an ancient
+  version of a package named "Paste-Deploy-0.1" (note the dash) when
+  trying to find the "Paste" distribution and somehow believes it's
+  the latest version of "Paste".  It also somehow "helpfully" decides
+  to check out a version of this package from SVN.  We pin the Paste
+  dependency version to a version greater than 1.7 to work around
+  this ``easy_install`` bug.
+
+Documentation
+-------------
+
+- Fix "Hybrid" narrative chapter: stop claiming that ``<view>``
+  statements that mention a route_name need to come afer (in XML
+  order) the ``<route>`` statement which creates the route.  This
+  hasn't been true since 1.1a1.
+
+- "What's New in ``repoze.bfg`` 1.1" document added to narrative
+  documentation.
+
+Features
+--------
+
+- Add a new event type: ``repoze.bfg.events.AfterTraversal``.  Events
+  of this type will be sent after traversal is completed, but before
+  any view code is invoked.  Like ``repoze.bfg.events.NewRequest``,
+  This event will have a single attribute: ``request`` representing
+  the current request.  Unlike the request attribute of
+  ``repoze.bfg.events.NewRequest`` however, during an AfterTraversal
+  event, the request object will possess attributes set by the
+  traverser, most notably ``context``, which will be the context used
+  when a view is found and invoked.  The interface
+  ``repoze.bfg.events.IAfterTraversal`` can be used to subscribe to
+  the event.  For example::
+
+    <subscriber for="repoze.bfg.interfaces.IAfterTraversal"
+                handler="my.app.handle_after_traverse"/>
+
+  Like any framework event, a subscriber function should expect one
+  parameter: ``event``.
+
+Dependencies
+------------
+
+- Rather than depending on ``chameleon.core`` and ``chameleon.zpt``
+  distributions individually, depend on Malthe's repackaged
+  ``Chameleon`` distribution (which includes both ``chameleon.core``
+  and ``chameleon.zpt``).
+
+1.1b1 (2009-11-01)
+==================
+
+Bug Fixes
+---------
+
+- The routes root factory called route factories and the default route
+  factory with an environ rather than a request.  One of the symptoms
+  of this bug: applications generated using the ``bfg_zodb`` paster
+  template in 1.1a9 did not work properly.
+
+- Reinstate ``renderer`` alias for ``view_renderer`` in the
+  ``<route>`` ZCML directive (in-the-wild 1.1a bw compat).
+
+- ``bfg_routesalchemy`` paster template: change ``<route>``
+  declarations: rename ``renderer`` attribute to ``view_renderer``.
+
+- Header values returned by the ``authtktauthenticationpolicy``
+  ``remember`` and ``forget`` methods would be of type ``unicode``.
+  This violated the WSGI spec, causing a ``TypeError`` to be raised
+  when these headers were used under ``mod_wsgi``.
+
+- If a BFG app that had a route matching the root URL was mounted
+  under a path in modwsgi, ala ``WSGIScriptAlias /myapp
+  /Users/chrism/projects/modwsgi/env/bfg.wsgi``, the home route (a
+  route with the path of ``'/'`` or ``''``) would not match when the
+  path ``/myapp`` was visited (only when the path ``/myapp/`` was
+  visited).  This is now fixed: if the urldispatch root factory notes
+  that the PATH_INFO is empty, it converts it to a single slash before
+  trying to do matching.
+
+Documentation
+-------------
+
+- In ``<route>`` declarations in tutorial ZCML, rename ``renderer``
+  attribute to ``view_renderer`` (fwd compat).
+
+- Fix various tutorials broken by 1.1a9 ``<route>`` directive changes.
+
+Internal
+--------
+
+- Deal with a potential circref in the traversal module.
+
+1.1a9 (2009-10-31)
+==================
+
+Bug Fixes
+---------
+
+- An incorrect ZCML conflict would be encountered when the
+  ``request_param`` predicate attribute was used on the ZCML ``view``
+  directive if any two otherwise same-predicated views had the
+  combination of a predicate value with an ``=`` sign and one without
+  (e.g. ``a`` vs. ``a=123``).
+
+Features
+--------
+
+- In previous versions of BFG, the "root factory" (the ``get_root``
+  callable passed to ``make_app`` or a function pointed to by the
+  ``factory`` attribute of a route) was called with a "bare" WSGI
+  environment.  In this version, and going forward, it will be called
+  with a ``request`` object.  The request object passed to the factory
+  implements dictionary-like methods in such a way that existing root
+  factory code which expects to be passed an environ will continue to
+  work.
+
+- The ``__call__`` of a plugin "traverser" implementation (registered
+  as an adapter for ``ITraverser`` or ``ITraverserFactory``) will now
+  receive a *request* as the single argument to its ``__call__``
+  method.  In previous versions it was passed a WSGI ``environ``
+  object.  The request object passed to the factory implements
+  dictionary-like methods in such a way that existing traverser code
+  which expects to be passed an environ will continue to work.
+
+- The ZCML ``route`` directive's attributes ``xhr``,
+  ``request_method``, ``path_info``, ``request_param``, ``header`` and
+  ``accept`` are now *route* predicates rather than *view* predicates.
+  If one or more of these predicates is specified in the route
+  configuration, all of the predicates must return true for the route
+  to match a request.  If one or more of the route predicates
+  associated with a route returns ``False`` when checked during a
+  request, the route match fails, and the next match in the routelist
+  is tried.  This differs from the previous behavior, where no route
+  predicates existed and all predicates were considered view
+  predicates, because in that scenario, the next route was not tried.
+
+Documentation
+-------------
+
+- Various changes were made to narrative and API documentation
+  supporting the change from passing a request rather than an environ
+  to root factories and traversers.
+
+Internal
+--------
+
+- The request implements dictionary-like methods that mutate and query
+  the WSGI environ.  This is only for the purpose of backwards
+  compatibility with root factories which expect an ``environ`` rather
+  than a request.
+
+- The ``repoze.bfg.request.create_route_request_factory`` function,
+  which returned a request factory was removed in favor of a
+  ``repoze.bfg.request.route_request_interface`` function, which
+  returns an interface.
+
+- The ``repoze.bfg.request.Request`` class, which is a subclass of
+  ``webob.Request`` now defines its own ``__setattr__``,
+  ``__getattr__`` and ``__delattr__`` methods, which override the
+  default WebOb behavior.  The default WebOb behavior stores
+  attributes of the request in ``self.environ['webob.adhoc_attrs']``,
+  and retrieves them from that dictionary during a ``__getattr__``.
+  This behavior was undesirable for speed and "expectation" reasons.
+  Now attributes of the ``request`` are stored in ``request.__dict__``
+  (as you otherwise might expect from an object that did not override
+  these methods).
+
+- The router no longer calls ``repoze.bfg.traversal._traverse`` and
+  does its work "inline" (speed).
+
+- Reverse the order in which the router calls the request factory and
+  the root factory.  The request factory is now called first; the
+  resulting request is passed to the root factory.
+
+- The ``repoze.bfg.request.request_factory`` function has been
+  removed.  Its functionality is no longer required.
+
+- The "routes root factory" that wraps the default root factory when
+  there are routes mentioned in the configuration now attaches an
+  interface to the request via ``zope.interface.directlyProvides``.
+  This replaces logic in the (now-gone)
+  ``repoze.bfg.request.request_factory`` function.
+
+- The ``route`` and ``view`` ZCML directives now register an interface
+  as a named utility (retrieved from
+  ``repoze.bfg.request.route_request_interface``) rather than a
+  request factory (the previous return value of the now-missing 
+  ``repoze.bfg.request.create_route_request_factory``.
+
+- The ``repoze.bfg.functional`` module was renamed to
+  ``repoze.bfg.compat``.
+
+Backwards Incompatibilities
+---------------------------
+
+- Explicitly revert the feature introduced in 1.1a8: where the name
+  ``root`` is available as an attribute of the request before a
+  NewRequest event is emitted.  This makes some potential future
+  features impossible, or at least awkward (such as grouping traversal
+  and view lookup into a single adapter lookup).
+
+- The ``containment``, ``attr`` and ``renderer`` attributes of the
+  ``route`` ZCML directive were removed.
+
+1.1a8 (2009-10-27)
+==================
+
+Features
+--------
+
+- Add ``path_info`` view configuration predicate.
+
+- ``paster bfgshell`` now supports IPython if it's available for
+  import.  Thanks to Daniel Holth for the initial patch.
+
+- Add ``repoze.bfg.testing.registerSettings`` API, which is documented
+  in the "repoze.bfg.testing" API chapter.  This allows for
+  registration of "settings" values obtained via
+  ``repoze.bfg.settings.get_settings()`` for use in unit tests.
+
+- The name ``root`` is available as an attribute of the request
+  slightly earlier now (before a NewRequest event is emitted).
+  ``root`` is the result of the application "root factory".
+
+- Added ``max_age`` parameter to ``authtktauthenticationpolicy`` ZCML
+  directive.  If this value is set, it must be an integer representing
+  the number of seconds which the auth tkt cookie will survive.
+  Mainly, its existence allows the auth_tkt cookie to survive across
+  browser sessions.
+
+Bug Fixes
+---------
+
+- Fix bug encountered during "scan" (when ``<scan ..>`` directive is
+  used in ZCML) introduced in 1.1a7.  Symptom: ``AttributeError:
+  object has no attribute __provides__`` raised at startup time.
+
+- The ``reissue_time`` argument to the ``authtktauthenticationpolicy``
+  ZCML directive now actually works.  When it is set to an integer
+  value, an authticket set-cookie header is appended to the response
+  whenever a request requires authentication and 'now' minus the
+  authticket's timestamp is greater than ``reissue_time`` seconds.
+
+Documentation
+-------------
+
+- Add a chapter titled "Request and Response" to the narrative
+  documentation, content cribbed from the WebOb documentation.
+
+- Call out predicate attributes of ZCML directive within "Views"
+  chapter.
+
+- Fix route_url documentation (``_query`` argument documented as
+  ``query`` and ``_anchor`` argument documented as ``anchor``).
+
+Backwards Incompatibilities
+---------------------------
+
+- The ``authtkt`` authentication policy ``remember`` method now no
+  longer honors ``token`` or ``userdata`` keyword arguments.
+
+Internal
+--------
+
+- Change how ``bfg_view`` decorator works when used as a class method
+  decorator.  In 1.1a7, the``scan``directive actually tried to grope
+  every class in scanned package at startup time, calling ``dir``
+  against each found class, and subsequently invoking ``getattr``
+  against each thing found by ``dir`` to see if it was a method.  This
+  led to some strange symptoms (e.g. ``AttributeError: object has no
+  attribute __provides__``), and was generally just a bad idea.  Now,
+  instead of groping classes for methods at startup time, we just
+  cause the ``bfg_view`` decorator itself to populate the method's
+  class' ``__dict__`` when it is used as a method decorator.  This
+  also requires a nasty _getframe thing but it's slightly less nasty
+  than the startup time groping behavior.  This is essentially a
+  reversion back to 1.1a6 "grokking" behavior plus some special magic
+  for using the ``bfg_view`` decorator as method decorator inside the
+  ``bfg_view`` class itself.
+
+- The router now checks for a ``global_response_headers`` attribute of
+  the request object before returning a response.  If this value
+  exists, it is presumed to be a sequence of two-tuples, representing
+  a set of headers to append to the 'normal' response headers.  This
+  feature is internal, rather than exposed externally, because it's
+  unclear whether it will stay around in the long term.  It was added
+  to support the ``reissue_time`` feature of the authtkt
+  authentication policy.
+
+- The interface ITraverserFactory is now just an alias for ITraverser.
+
+1.1a7 (2009-10-18)
+==================
+
+Features
+--------
+
+- More than one ``@bfg_view`` decorator may now be stacked on top of
+  any number of others.  Each invocation of the decorator registers a
+  single view configuration.  For instance, the following combination
+  of decorators and a function will register two view configurations
+  for the same view callable::
+
+    from repoze.bfg.view import bfg_view
+
+    @bfg_view(name='edit')
+    @bfg_view(name='change')
+    def edit(context, request):
+        pass
+
+  This makes it possible to associate more than one view configuration
+  with a single callable without requiring any ZCML.
+
+- The ``@bfg_view`` decorator can now be used against a class method::
+
+    from webob import Response
+    from repoze.bfg.view import bfg_view
+
+    class MyView(object):
+        def __init__(self, context, request):
+            self.context = context
+            self.request = request
+
+        @bfg_view(name='hello')
+        def amethod(self):
+            return Response('hello from %s!' % self.context)
+
+  When the bfg_view decorator is used against a class method, a view
+  is registered for the *class* (it's a "class view" where the "attr"
+  happens to be the name of the method it is attached to), so the
+  class it's defined within must have a suitable constructor: one that
+  accepts ``context, request`` or just ``request``.
+
+Documentation
+-------------
+
+- Added ``Changing the Traverser`` and ``Changing How
+  :mod:`repoze.bfg.url.model_url` Generates a URL`` to the "Hooks"
+  narrative chapter of the docs.
+
+Internal
+--------
+
+- Remove ``ez_setup.py`` and imports of it within ``setup.py``.  In
+  the new world, and as per virtualenv setup instructions, people will
+  already have either setuptools or distribute.
+
+1.1a6 (2009-10-15)
+==================
+
+Features
+--------
+
+- Add ``xhr``, ``accept``, and ``header`` view configuration
+  predicates to ZCML view declaration, ZCML route declaration, and
+  ``bfg_view`` decorator.  See the ``Views`` narrative documentation
+  chapter for more information about these predicates.
+
+- Add ``setUp`` and ``tearDown`` functions to the
+  ``repoze.bfg.testing`` module.  Using ``setUp`` in a test setup and
+  ``tearDown`` in a test teardown is now the recommended way to do
+  component registry setup and teardown.  Previously, it was
+  recommended that a single function named
+  ``repoze.bfg.testing.cleanUp`` be called in both the test setup and
+  tear down.  ``repoze.bfg.testing.cleanUp`` still exists (and will
+  exist "forever" due to its widespread use); it is now just an alias
+  for ``repoze.bfg.testing.setUp`` and is nominally deprecated.
+
+- The BFG component registry is now available in view and event
+  subscriber code as an attribute of the request
+  ie. ``request.registry``.  This fact is currently undocumented
+  except for this note, because BFG developers never need to interact
+  with the registry directly anywhere else.
+
+- The BFG component registry now inherits from ``dict``, meaning that
+  it can optionally be used as a simple dictionary.  *Component*
+  registrations performed against it via e.g. ``registerUtility``,
+  ``registerAdapter``, and similar API methods are kept in a
+  completely separate namespace than its dict members, so using the
+  its component API methods won't effect the keys and values in the
+  dictionary namespace.  Likewise, though the component registry
+  "happens to be" a dictionary, use of mutating dictionary methods
+  such as ``__setitem__`` will have no influence on any component
+  registrations made against it.  In other words, the registry object
+  you obtain via e.g. ``repoze.bfg.threadlocal.get_current_registry``
+  or ``request.registry`` happens to be both a component registry and
+  a dictionary, but using its component-registry API won't impact data
+  added to it via its dictionary API and vice versa.  This is a
+  forward compatibility move based on the goals of "marco".
+
+- Expose and document ``repoze.bfg.testing.zcml_configure`` API.  This
+  function populates a component registry from a ZCML file for testing
+  purposes.  It is documented in the "Unit and Integration Testing"
+  chapter.
+
+Documentation
+-------------
+
+- Virtual hosting narrative docs chapter updated with info about
+  ``mod_wsgi``.
+
+- Point all index URLs at the literal 1.1 index (this alpha cycle may
+  go on a while).
+
+- Various tutorial test modules updated to use
+  ``repoze.bfg.testing.setUp`` and ``repoze.bfg.testing.tearDown``
+  methods in order to encourage this as best practice going forward.
+
+- Added "Creating Integration Tests" section to unit testing narrative
+  documentation chapter.  As a result, the name of the unittesting
+  chapter is now "Unit and Integration Testing".
+
+Backwards Incompatibilities
+---------------------------
+
+- Importing ``getSiteManager`` and ``get_registry`` from
+  ``repoze.bfg.registry`` is no longer supported.  These imports were
+  deprecated in repoze.bfg 1.0.  Import of ``getSiteManager`` should
+  be done as ``from zope.component import getSiteManager``.  Import of
+  ``get_registry`` should be done as ``from repoze.bfg.threadlocal
+  import get_current_registry``.  This was done to prevent a circular
+  import dependency.
+
+- Code bases which alternately invoke both
+  ``zope.testing.cleanup.cleanUp`` and ``repoze.bfg.testing.cleanUp``
+  (treating them equivalently, using them interchangeably) in the
+  setUp/tearDown of unit tests will begin to experience test failures
+  due to lack of test isolation.  The "right" mechanism is
+  ``repoze.bfg.testing.cleanUp`` (or the combination of
+  ``repoze.bfg.testing.setUp`` and
+  ``repoze.bfg.testing.tearDown``). but a good number of legacy
+  codebases will use ``zope.testing.cleanup.cleanUp`` instead.  We
+  support ``zope.testing.cleanup.cleanUp`` but not in combination with
+  ``repoze.bfg.testing.cleanUp`` in the same codebase.  You should use
+  one or the other test cleanup function in a single codebase, but not
+  both.
+
+Internal
+--------
+
+- Created new ``repoze.bfg.configuration`` module which assumes
+  responsibilities previously held by the ``repoze.bfg.registry`` and
+  ``repoze.bfg.router`` modules (avoid a circular import dependency).
+
+- The result of the ``zope.component.getSiteManager`` function in unit
+  tests set up with ``repoze.bfg.testing.cleanUp`` or
+  ``repoze.bfg.testing.setUp`` will be an instance of
+  ``repoze.bfg.registry.Registry`` instead of the global
+  ``zope.component.globalregistry.base`` registry.  This also means
+  that the threadlocal ZCA API functions such as ``getAdapter`` and
+  ``getUtility`` as well as internal BFG machinery (such as
+  ``model_url`` and ``route_url``) will consult this registry within
+  unit tests. This is a forward compatibility move based on the goals
+  of "marco".
+
+- Removed ``repoze.bfg.testing.addCleanUp`` function and associated
+  module-scope globals.  This was never an API.
+
+1.1a5 (2009-10-10)
+==================
+
+Documentation
+-------------
+
+- Change "Traversal + ZODB" and "URL Dispatch + SQLAlchemy" Wiki
+  tutorials to make use of the new-to-1.1 "renderer" feature (return
+  dictionaries from all views).
+
+- Add tests to the "URL Dispatch + SQLAlchemy" tutorial after the
+  "view" step.
+
+- Added a diagram of model graph traversal to the "Traversal"
+  narrative chapter of the documentation.
+
+- An ``exceptions`` API chapter was added, documenting the new
+  ``repoze.bfg.exceptions`` module.
+
+- Describe "request-only" view calling conventions inside the
+  urldispatch narrative chapter, where it's most helpful.
+
+- Add a diagram which explains the operation of the BFG router to the
+  "Router" narrative chapter.
+
+Features
+--------
+
+- Add a new ``repoze.bfg.testing`` API: ``registerRoute``, for
+  registering routes to satisfy calls to
+  e.g. ``repoze.bfg.url.route_url`` in unit tests.
+
+- The ``notfound`` and ``forbidden`` ZCML directives now accept the
+  following addtional attributes: ``attr``, ``renderer``, and
+  ``wrapper``.  These have the same meaning as they do in the context
+  of a ZCML ``view`` directive.
+
+- For behavior like Django's ``APPEND_SLASH=True``, use the
+  ``repoze.bfg.view.append_slash_notfound_view`` view as the Not Found
+  view in your application.  When this view is the Not Found view
+  (indicating that no view was found), and any routes have been
+  defined in the configuration of your application, if the value of
+  ``PATH_INFO`` does not already end in a slash, and if the value of
+  ``PATH_INFO`` *plus* a slash matches any route's path, do an HTTP
+  redirect to the slash-appended PATH_INFO.  Note that this will
+  *lose* ``POST`` data information (turning it into a GET), so you
+  shouldn't rely on this to redirect POST requests.
+
+- Speed up ``repoze.bfg.location.lineage`` slightly.
+
+- Speed up ``repoze.bfg.encode.urlencode`` (nee'
+  ``repoze.bfg.url.urlencode``) slightly.
+
+- Speed up ``repoze.bfg.traversal.model_path``.
+
+- Speed up ``repoze.bfg.traversal.model_path_tuple`` slightly.
+
+- Speed up ``repoze.bfg.traversal.traverse`` slightly.
+
+- Speed up ``repoze.bfg.url.model_url`` slightly.
+
+- Speed up ``repoze.bfg.url.route_url`` slightly.
+
+- Sped up ``repoze.bfg.traversal.ModelGraphTraverser:__call__``
+  slightly.
+
+- Minor speedup of ``repoze.bfg.router.Router.__call__``.
+
+- New ``repoze.bfg.exceptions`` module was created to house exceptions
+  that were previously sprinkled through various modules.
+
+Internal
+--------
+
+- Move ``repoze.bfg.traversal._url_quote`` into ``repoze.bfg.encode``
+  as ``url_quote``.
+
+Deprecations
+------------
+
+- The import of ``repoze.bfg.view.NotFound`` is deprecated in favor of
+  ``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.
+
+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`` 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 now 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.
+
+- 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.
+
+1.1a4 (2009-09-23)
+==================
+
+Bug Fixes
+---------
+
+- On 64-bit Linux systems, views that were members of a multiview
+  (orderings of views with predicates) were not evaluated in the
+  proper order.  Symptom: in a configuration that had two views with
+  the same name but one with a ``request_method=POST`` predicate and
+  one without, the one without the predicate would be called
+  unconditionally (even if the request was a POST request).  Thanks
+  much to Sebastien Douche for providing the buildbots that pointed
+  this out.
+
+Documentation
+-------------
+
+- Added a tutorial which explains how to use ``repoze.session``
+  (ZODB-based sessions) in a ZODB-based repoze.bfg app.
+
+- Added a tutorial which explains how to add ZEO to a ZODB-based
+  ``repoze.bfg`` application.
+
+- Added a tutorial which explains how to run a ``repoze.bfg``
+  application under `mod_wsgi <http://code.google.com/p/modwsgi/>`_.
+  See "Running a repoze.bfg Application under mod_wsgi" in the
+  tutorials section of the documentation.
+
+Features
+--------
+
+- Add a ``repoze.bfg.url.static_url`` API which is capable of
+  generating URLs to static resources defined by the ``<static>`` ZCML
+  directive.  See the "Views" narrative chapter's section titled
+  "Generating Static Resource URLs" for more information.
+
+- Add a ``string`` renderer.  This renderer converts a non-Response
+  return value of any view callble into a string.  It is documented in
+  the "Views" narrative chapter.
+
+- Give the ``route`` ZCML directive the ``view_attr`` and
+  ``view_renderer`` parameters (bring up to speed with 1.1a3
+  features).  These can also be spelled as ``attr`` and ``renderer``.
+
+Backwards Incompatibilities
+---------------------------
+
+- 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.
+
+Internal
+--------
+
+- The way ``bfg_view`` declarations are scanned for has been modified.
+  This should have no external effects.
+
+- Speed: do not register an ITraverserFactory in configure.zcml;
+  instead rely on queryAdapter and a manual default to
+  ModelGraphTraverser.
+
+- 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.
+
+1.1a3 (2009-09-16)
+==================
+
+Documentation
+-------------
+
+- The "Views" narrative chapter in the documentation has been updated
+  extensively to discuss "renderers".
+
+Features
+--------
+
+- A ``renderer`` attribute has been added to view configurations,
+  replacing the previous (1.1a2) version's ``template`` attribute.  A
+  "renderer" is an object which accepts the return value of a view and
+  converts it to a string.  This includes, but is not limited to,
+  templating systems.
+
+- A new interface named ``IRenderer`` was added.  The existing
+  interface, ``ITemplateRenderer`` now derives from this new
+  interface.  This interface is internal.
+
+- A new interface named ``IRendererFactory`` was added.  An existing
+  interface named ``ITemplateRendererFactory`` now derives from this
+  interface.  This interface is internal.
+
+- The ``view`` attribute of the ``view`` ZCML directive is no longer
+  required if the ZCML directive also has a ``renderer`` attribute.
+  This is useful when the renderer is a template renderer and no names
+  need be passed to the template at render time.
+
+- A new zcml directive ``renderer`` has been added.  It is documented
+  in the "Views" narrative chapter of the documentation.
+
+- A ZCML ``view`` directive (and the associated ``bfg_view``
+  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).
+
+Dependencies
+------------
+
+- When used under Python < 2.6, BFG now has an installation time
+  dependency on the ``simplejson`` package.
+
+Deprecations
+------------
+
+- The ``repoze.bfg.testing.registerDummyRenderer`` API has been
+  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"; its existence has been removed from the
+  documentation, however.
+
+- 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.
+
+Backwards Incompatibilities
+---------------------------
+
+- The ``ITemplateRenderer`` interface has been changed.  Previously
+  its ``__call__`` method accepted ``**kw``.  It now accepts a single
+  positional parameter named ``kw`` (REVISED: it accepts two
+  positional parameters as of 1.1a4: ``value`` and ``system``).  This
+  is mostly an internal change, but it was exposed in APIs in one
+  place: if you've used the
+  ``repoze.bfg.testing.registerDummyRenderer`` API in your tests with
+  a custom "renderer" argument with your own renderer implementation,
+  you will need to change that renderer implementation to accept
+  ``kw`` instead of ``**kw`` in its ``__call__`` method (REVISED: make
+  it accept ``value`` and ``system`` positional arguments as of 1.1a4).
+
+- The ``ITemplateRendererFactory`` interface has been changed.
+  Previously its ``__call__`` method accepted an ``auto_reload``
+  keyword parameter.  Now its ``__call__`` method accepts no keyword
+  parameters.  Renderers are now themselves responsible for
+  determining details of auto-reload.  This is purely an internal
+  change.  This interface was never external.
+
+- The ``template_renderer`` ZCML directive introduced in 1.1a2 has
+  been removed.  It has been replaced by the ``renderer`` directive.
+
+- The previous release (1.1a2) added a view configuration attribute
+  named ``template``.  In this release, the attribute has been renamed
+  to ``renderer``.  This signifies that the attribute is more generic:
+  it can now be not just a template name but any renderer name (ala
+  ``json``).  
+
+- In the previous release (1.1a2), the Chameleon text template
+  renderer was used if the system didn't associate the ``template``
+  view configuration value with a filename with a "known" extension.
+  In this release, you must use a ``renderer`` attribute which is a
+  path that ends with a ``.txt`` extension
+  (e.g. ``templates/foo.txt``) to use the Chameleon text renderer.
+
+1.1a2 (2009-09-14)
+==================
+
+Features
+--------
+
+- A ZCML ``view`` directive (and the associated ``bfg_view``
+  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.  See the section named "Views That Have a ``template``"
+  in the "Views" narrative documentation chapter for more information.
+
+1.1a1 (2009-09-06)
+==================
+
+Bug Fixes
+---------
+
+- "tests" module removed from the bfg_alchemy paster template; these
+  tests didn't work.
+
+- Bugfix: the ``discriminator`` for the ZCML "route" directive was
+  incorrect.  It was possible to register two routes that collided
+  without the system spitting out a ConfigurationConflictError at
+  startup time.
+
+Features
+--------
+
+- Feature addition: view predicates.  These are exposed as the
+  ``request_method``, ``request_param``, and ``containment``
+  attributes of a ZCML ``view`` declaration, or the respective
+  arguments to a ``@bfg_view`` decorator.  View predicates can be used
+  to register a view for a more precise set of environment parameters
+  than was previously possible.  For example, you can register two
+  views with the same ``name`` with different ``request_param``
+  attributes.  If the ``request.params`` dict contains 'foo'
+  (request_param="foo"), one view might be called; if it contains
+  'bar' (request_param="bar"), another view might be called.
+  ``request_param`` can also name a key/value pair ala ``foo=123``.
+  This will match only when the ``foo`` key is in the request.params
+  dict and it has the value '123'.  This particular example makes it
+  possible to write separate view functions for different form
+  submissions.  The other predicates, ``containment`` and
+  ``request_method`` work similarly.  ``containment`` is a view
+  predicate that will match only when the context's graph lineage has
+  an object possessing a particular class or interface, for example.
+  ``request_method`` is a view predicate that will match when the HTTP
+  ``REQUEST_METHOD`` equals some string (eg. 'POST').
+
+- The ``@bfg_view`` decorator now accepts three additional arguments:
+  ``request_method``, ``request_param``, and ``containment``.
+  ``request_method`` is used when you'd like the view to match only a
+  request with a particular HTTP ``REQUEST_METHOD``; a string naming
+  the ``REQUEST_METHOD`` can also be supplied as ``request_type`` for
+  backwards compatibility.  ``request_param`` is used when you'd like
+  a view to match only a request that contains a particular
+  ``request.params`` key (with or without a value).  ``containment``
+  is used when you'd like to match a request that has a context that
+  has some class or interface in its graph lineage.  These are
+  collectively known as "view predicates".
+
+- The ``route`` ZCML directive now honors ``view_request_method``,
+  ``view_request_param`` and ``view_containment`` attributes, which
+  pass along these values to the associated view if any is provided.
+  Additionally, the ``request_type`` attribute can now be spelled as
+  ``view_request_type``, and ``permission`` can be spelled as
+  ``view_permission``.  Any attribute which starts with ``view_`` can
+  now be spelled without the ``view_`` prefix, so ``view_for`` can be
+  spelled as ``for`` now, etc.  Both forms are documented in the
+  urldispatch narraitve documentation chapter.
+
+- The ``request_param`` ZCML view directive attribute (and its
+  ``bfg_view`` decorator cousin) can now specify both a key and a
+  value.  For example, ``request_param="foo=123"`` means that the foo
+  key must have a value of ``123`` for the view to "match".
+
+- Allow ``repoze.bfg.traversal.find_interface`` API to use a class
+  object as the argument to compare against the ``model`` passed in.
+  This means you can now do ``find_interface(model, SomeClass)`` and
+  the first object which is found in the lineage which has
+  ``SomeClass`` as its class (or the first object found which has
+  ``SomeClass`` as any of its superclasses) will be returned.
+
+- Added ``static`` ZCML directive which registers a route for a view
+  that serves up files in a directory.  See the "Views" narrative
+  documentation chapter's "Serving Static Resources Using a ZCML
+  Directive" section for more information.
+
+- The ``repoze.bfg.view.static`` class now accepts a string as its
+  first argument ("root_dir") that represents a package-relative name
+  e.g. ``somepackage:foo/bar/static``.  This is now the preferred
+  mechanism for spelling package-relative static paths using this
+  class.  A ``package_name`` keyword argument has been left around for
+  backwards compatibility.  If it is supplied, it will be honored.
+
+- The API ``repoze.bfg.testing.registerView`` now takes a
+  ``permission`` argument.  Use this instead of using
+  ``repoze.bfg.testing.registerViewPermission``.
+
+- The ordering of route declarations vs. the ordering of view
+  declarations that use a "route_name" in ZCML no longer matters.
+  Previously it had been impossible to use a route_name from a route
+  that had not yet been defined in ZCML (order-wise) within a "view"
+  declaration.
+
+- The repoze.bfg router now catches both
+  ``repoze.bfg.security.Unauthorized`` and
+  ``repoze.bfg.view.NotFound`` exceptions while rendering a view.
+  When the router catches an ``Unauthorized``, it returns the
+  registered forbidden view.  When the router catches a ``NotFound``,
+  it returns the registered notfound view.
+
+Internal
+--------
+
+- Change urldispatch internals: Route object is now constructed using
+  a path, a name, and a factory instead of a name, a matcher, a
+  generator, and a factory.
+
+- Move (non-API) default_view, default_forbidden_view, and
+  default_notfound_view functions into the ``repoze.bfg.view`` module
+  (moved from ``repoze.bfg.router``).
+
+- Removed ViewPermissionFactory from ``repoze.bfg.security``.  View
+  permission checking is now done by registering and looking up an
+  ISecuredView.
+
+- The ``static`` ZCML directive now uses a custom root factory when
+  constructing a route.
+
+- The interface ``IRequestFactories`` was removed from the
+  repoze.bfg.interfaces module.  This interface was never an API.
+
+- The function named ``named_request_factories`` and the data
+  structure named ``DEFAULT_REQUEST_FACTORIES`` have been removed from
+  the ``repoze.bfg.request`` module.  These were never APIs.
+
+- The ``IViewPermissionFactory`` interface has been removed.  This was
+  never an API.
+
+Documentation
+-------------
+
+- Request-only-convention examples in the "Views" narrative
+  documentation were broken.
+
+- Fixed documentation bugs related to forget and remember in security API
+  docs.
+
+- Fixed documentation for ``repoze.bfg.view.static`` (in narrative
+  ``Views`` chapter).
+
+Deprecations
+------------
+
+- The API ``repoze.bfg.testing.registerViewPermission`` has been
+  deprecated.
+
+Backwards Incompatibilities
+---------------------------
+
+- The interfaces ``IPOSTRequest``, ``IGETRequest``, ``IPUTRequest``,
+  ``IDELETERequest``, and ``IHEADRequest`` have been removed from the
+  ``repoze.bfg.interfaces`` module.  These were not documented as APIs
+  post-1.0.  Instead of using one of these, use a ``request_method``
+  ZCML attribute or ``request_method`` bfg_view decorator parameter
+  containing an HTTP method name (one of ``GET``, ``POST``, ``HEAD``,
+  ``PUT``, ``DELETE``) instead of one of these interfaces if you were
+  using one explicitly.  Passing a string in the set (``GET``,
+  ``HEAD``, ``PUT``, ``POST``, ``DELETE``) as a ``request_type``
+  argument will work too.  Rationale: instead of relying on interfaces
+  attached to the request object, BFG now uses a "view predicate" to
+  determine the request type.
+
+- Views registered without the help of the ZCML ``view`` directive are
+  now responsible for performing their own authorization checking.
+
+- The ``registry_manager`` backwards compatibility alias importable
+  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.
+
+- The ``INotFoundAppFactory`` interface has been removed; it has
+  been deprecated since repoze.bfg 0.9.  If you have something like
+  the following in your ``configure.zcml``::
+
+   <utility provides="repoze.bfg.interfaces.INotFoundAppFactory"
+            component="helloworld.factories.notfound_app_factory"/>
+
+  Replace it with something like::
+
+   <notfound 
+       view="helloworld.views.notfound_view"/>
+
+  See "Changing the Not Found View" in the "Hooks" chapter of the
+  documentation for more information.
+
+- The ``IUnauthorizedAppFactory`` interface has been removed; it has
+  been deprecated since repoze.bfg 0.9.  If you have something like
+  the following in your ``configure.zcml``::
+
+   <utility provides="repoze.bfg.interfaces.IUnauthorizedAppFactory"
+            component="helloworld.factories.unauthorized_app_factory"/>
+
+  Replace it with something like::
+
+   <forbidden
+       view="helloworld.views.forbidden_view"/>
+
+  See "Changing the Forbidden View" in the "Hooks" chapter of the
+  documentation for more information.
+
+- ``ISecurityPolicy``-based security policies, deprecated since
+  repoze.bfg 0.9, have been removed.  If you have something like this
+  in your ``configure.zcml``, it will no longer work::
+
+     <utility
+       provides="repoze.bfg.interfaces.ISecurityPolicy"
+       factory="repoze.bfg.security.RemoteUserInheritingACLSecurityPolicy"
+      />
+
+  If ZCML like the above exists in your application, you will receive
+  an error at startup time.  Instead of the above, you'll need
+  something like::
+
+     <remoteuserauthenticationpolicy/>
+     <aclauthorizationpolicy/>
+
+  This is just an example.  See the "Security" chapter of the
+  repoze.bfg documentation for more information about configuring
+  security policies.
+
+- Custom ZCML directives which register an authentication or
+  authorization policy (ala "authtktauthenticationpolicy" or
+  "aclauthorizationpolicy") should register the policy "eagerly" in
+  the ZCML directive instead of from within a ZCML action.  If an
+  authentication or authorization policy is not found in the component
+  registry by the view machinery during deferred ZCML processing, view
+  security will not work as expected.
