Released on September 29th 2011, codename Rakija

- Refactored session support into a session interface so that
the implementation of the sessions can be changed without
having to override the Flask class.
- Empty session cookies are now deleted properly automatically.
- View functions can now opt out of getting the automatic
OPTIONS implementation.
- HTTP exceptions and Bad Request errors can now be trapped so that they
show up normally in the traceback.
- Flask in debug mode is now detecting some common problems and tries to
warn you about them.
- Flask in debug mode will now complain with an assertion error if a view
was attached after the first request was handled. This gives earlier
feedback when users forget to import view code ahead of time.
- Added the ability to register callbacks that are only triggered once at
the beginning of the first request. (:meth:`Flask.before_first_request`)
- Malformed JSON data will now trigger a bad request HTTP exception instead
of a value error which usually would result in a 500 internal server
error if not handled. This is a backwards incompatible change.
- Applications now not only have a root path where the resources and modules
are located but also an instance path which is the designated place to
drop files that are modified at runtime (uploads etc.). Also this is
conceptually only instance depending and outside version control so it's
the perfect place to put configuration files etc. For more information
see :ref:`instance-folders`.
- Added the ``APPLICATION_ROOT`` configuration variable.
- Implemented :meth:`~flask.testing.TestClient.session_transaction` to
easily modify sessions from the test environment.
- Refactored test client internally. The ``APPLICATION_ROOT`` configuration
variable as well as ``SERVER_NAME`` are now properly used by the test client
as defaults.
- Added :attr:`flask.views.View.decorators` to support simpler decorating of
pluggable (class-based) views.
- Fixed an issue where the test client if used with the "with" statement did not
trigger the execution of the teardown handlers.
- Added finer control over the session cookie parameters.
- HEAD requests to a method view now automatically dispatch to the `get`
method if no handler was implemented.
- Implemented the virtual :mod:`flask.ext` package to import extensions from.
- The context preservation on exceptions is now an integral component of
Flask itself and no longer of the test client. This cleaned up some
internal logic and lowers the odds of runaway request contexts in unittests.

correct names when blueprints or modules were involved.

blueprints.

Released on June 28th 2011, codename Grappa

- Added :meth:`~flask.Flask.make_default_options_response`
which can be used by subclasses to alter the default
behavior for ``OPTIONS`` responses.
- Unbound locals now raise a proper :exc:`RuntimeError` instead
of an :exc:`AttributeError`.
- Mimetype guessing and etag support based on file objects is now
deprecated for :func:`flask.send_file` because it was unreliable.
Pass filenames instead or attach your own etags and provide a
proper mimetype by hand.
- Static file handling for modules now requires the name of the
static folder to be supplied explicitly. The previous autodetection
was not reliable and caused issues on Google's App Engine. Until
1.0 the old behavior will continue to work but issue dependency
warnings.
- fixed a problem for Flask to run on jython.
- added a ``PROPAGATE_EXCEPTIONS`` configuration variable that can be
used to flip the setting of exception propagation which previously
was linked to ``DEBUG`` alone and is now linked to either ``DEBUG`` or
``TESTING``.
- Flask no longer internally depends on rules being added through the
`add_url_rule` function and can now also accept regular werkzeug
rules added to the url map.
- Added an `endpoint` method to the flask application object which
allows one to register a callback to an arbitrary endpoint with
a decorator.
- Use Last-Modified for static file sending instead of Date which
was incorrectly introduced in 0.6.
- Added `create_jinja_loader` to override the loader creation process.
- Implemented a silent flag for `config.from_pyfile`.
- Added `teardown_request` decorator, for functions that should run at the end
of a request regardless of whether an exception occurred. Also the behavior
for `after_request` was changed. It's now no longer executed when an exception
is raised. See :ref:`upgrading-to-new-teardown-handling`
- Implemented :func:`flask.has_request_context`
- Deprecated `init_jinja_globals`. Override the
:meth:`~flask.Flask.create_jinja_environment` method instead to
achieve the same functionality.
- Added :func:`flask.safe_join`
- The automatic JSON request data unpacking now looks at the charset
mimetype parameter.
- Don't modify the session on :func:`flask.get_flashed_messages` if there
are no messages in the session.
- `before_request` handlers are now able to abort requests with errors.
- it is not possible to define user exception handlers. That way you can
provide custom error messages from a central hub for certain errors that
might occur during request processing (for instance database connection
errors, timeouts from remote resources etc.).
- Blueprints can provide blueprint specific error handlers.
- Implemented generic :ref:`views` (class-based views).

Bugfix release, released on December 31st 2010

- Fixed an issue where the default ``OPTIONS`` response was
not exposing all valid methods in the ``Allow`` header.
- Jinja2 template loading syntax now allows "./" in front of
a template load path. Previously this caused issues with
module setups.
- Fixed an issue where the subdomain setting for modules was
ignored for the static folder.
- Fixed a security problem that allowed clients to download arbitrary files
if the host server was a windows based operating system and the client
uses backslashes to escape the directory the files where exposed from.
