Version 0.11 ------------ Released on May 29th 2016, codename Absinthe. - Added support to serializing top-level arrays to :func:`flask.jsonify`. This introduces a security risk in ancient browsers. See :ref:`json-security` for details. - Added before_render_template signal. - Added `**kwargs` to :meth:`flask.Test.test_client` to support passing additional keyword arguments to the constructor of :attr:`flask.Flask.test_client_class`. - Added ``SESSION_REFRESH_EACH_REQUEST`` config key that controls the set-cookie behavior. If set to ``True`` a permanent session will be refreshed each request and get their lifetime extended, if set to ``False`` it will only be modified if the session actually modifies. Non permanent sessions are not affected by this and will always expire if the browser window closes. - Made Flask support custom JSON mimetypes for incoming data. - Added support for returning tuples in the form ``(response, headers)`` from a view function. - Added :meth:`flask.Config.from_json`. - Added :attr:`flask.Flask.config_class`. - Added :meth:`flask.config.Config.get_namespace`. - Templates are no longer automatically reloaded outside of debug mode. This can be configured with the new ``TEMPLATES_AUTO_RELOAD`` config key. - Added a workaround for a limitation in Python 3.3's namespace loader. - Added support for explicit root paths when using Python 3.3's namespace packages. - Added :command:`flask` and the ``flask.cli`` module to start the local debug server through the click CLI system. This is recommended over the old ``flask.run()`` method as it works faster and more reliable due to a different design and also replaces ``Flask-Script``. - Error handlers that match specific classes are now checked first, thereby allowing catching exceptions that are subclasses of HTTP exceptions (in ``werkzeug.exceptions``). This makes it possible for an extension author to create exceptions that will by default result in the HTTP error of their choosing, but may be caught with a custom error handler if desired. - Added :meth:`flask.Config.from_mapping`. - Flask will now log by default even if debug is disabled. The log format is now hardcoded but the default log handling can be disabled through the ``LOGGER_HANDLER_POLICY`` configuration key. - Removed deprecated module functionality. - Added the ``EXPLAIN_TEMPLATE_LOADING`` config flag which when enabled will instruct Flask to explain how it locates templates. This should help users debug when the wrong templates are loaded. - Enforce blueprint handling in the order they were registered for template loading. - Ported test suite to py.test. - Deprecated ``request.json`` in favour of ``request.get_json()``. - Add "pretty" and "compressed" separators definitions in jsonify() method. Reduces JSON response size when JSONIFY_PRETTYPRINT_REGULAR=False by removing unnecessary white space included by default after separators. - JSON responses are now terminated with a newline character, because it is a convention that UNIX text files end with a newline and some clients don't deal well when this newline is missing. See pallets/flask#1262 -- this came up originally as a part of https://github.com/kennethreitz/httpbin/issues/168 - The automatically provided ``OPTIONS`` method is now correctly disabled if the user registered an overriding rule with the lowercase-version ``options`` (issue ``#1288``). - ``flask.json.jsonify`` now supports the ``datetime.date`` type (pull request ``#1326``). - Don't leak exception info of already catched exceptions to context teardown handlers (pull request ``#1393``). - Allow custom Jinja environment subclasses (pull request ``#1422``). - ``flask.g`` now has ``pop()`` and ``setdefault`` methods. - Turn on autoescape for ``flask.templating.render_template_string`` by default (pull request ``#1515``). - ``flask.ext`` is now deprecated (pull request ``#1484``). - ``send_from_directory`` now raises BadRequest if the filename is invalid on the server OS (pull request ``#1763``). - Added the ``JSONIFY_MIMETYPE`` configuration variable (pull request ``#1728``). - Exceptions during teardown handling will no longer leave bad application contexts lingering around.
