[pyup-bot]

This PR updates flask from 1.1.4 to 2.0.2.

Changelog

2.0.2

-------------
Released 2021-10-04
- Fix type annotation for ``teardown_*`` methods. :issue:`4093`
- Fix type annotation for ``before_request`` and ``before_app_request``
decorators. :issue:`4104`
- Fixed the issue where typing requires template global
decorators to accept functions with no arguments. :issue:`4098`
- Support View and MethodView instances with async handlers. :issue:`4112`
- Enhance typing of ``app.errorhandler`` decorator. :issue:`4095`
- Fix registering a blueprint twice with differing names. :issue:`4124`
- Fix the type of ``static_folder`` to accept ``pathlib.Path``.
:issue:`4150`
- ``jsonify`` handles ``decimal.Decimal`` by encoding to ``str``.
:issue:`4157`
- Correctly handle raising deferred errors in CLI lazy loading.
:issue:`4096`
- The CLI loader handles ``**kwargs`` in a ``create_app`` function.
:issue:`4170`
- Fix the order of ``before_request`` and other callbacks that trigger
before the view returns. They are called from the app down to the
closest nested blueprint. :issue:`4229`

2.0.1

-------------
Released 2021-05-21
- Re-add the ``filename`` parameter in ``send_from_directory``. The
``filename`` parameter has been renamed to ``path``, the old name
is deprecated. :pr:`4019`
- Mark top-level names as exported so type checking understands
imports in user projects. :issue:`4024`
- Fix type annotation for ``g`` and inform mypy that it is a namespace
object that has arbitrary attributes. :issue:`4020`
- Fix some types that weren't available in Python 3.6.0. :issue:`4040`
- Improve typing for ``send_file``, ``send_from_directory``, and
``get_send_file_max_age``. :issue:`4044`, :pr:`4026`
- Show an error when a blueprint name contains a dot. The ``.`` has
special meaning, it is used to separate (nested) blueprint names and
the endpoint name. :issue:`4041`
- Combine URL prefixes when nesting blueprints that were created with
a ``url_prefix`` value. :issue:`4037`
- Roll back a change to the order that URL matching was done. The
URL is again matched after the session is loaded, so the session is
available in custom URL converters. :issue:`4053`
- Re-add deprecated ``Config.from_json``, which was accidentally
removed early. :issue:`4078`
- Improve typing for some functions using ``Callable`` in their type
signatures, focusing on decorator factories. :issue:`4060`
- Nested blueprints are registered with their dotted name. This allows
different blueprints with the same name to be nested at different
locations. :issue:`4069`
- ``register_blueprint`` takes a ``name`` option to change the
(pre-dotted) name the blueprint is registered with. This allows the
same blueprint to be registered multiple times with unique names for
``url_for``. Registering the same blueprint with the same name
multiple times is deprecated. :issue:`1091`
- Improve typing for ``stream_with_context``. :issue:`4052`

2.0.0

-------------
Released 2021-05-11
- Drop support for Python 2 and 3.5.
- Bump minimum versions of other Pallets projects: Werkzeug >= 2,
Jinja2 >= 3, MarkupSafe >= 2, ItsDangerous >= 2, Click >= 8. Be sure
to check the change logs for each project. For better compatibility
with other applications (e.g. Celery) that still require Click 7,
there is no hard dependency on Click 8 yet, but using Click 7 will
trigger a DeprecationWarning and Flask 2.1 will depend on Click 8.
- JSON support no longer uses simplejson. To use another JSON module,
override ``app.json_encoder`` and ``json_decoder``. :issue:`3555`
- The ``encoding`` option to JSON functions is deprecated. :pr:`3562`
- Passing ``script_info`` to app factory functions is deprecated. This
was not portable outside the ``flask`` command. Use
``click.get_current_context().obj`` if it's needed. :issue:`3552`
- The CLI shows better error messages when the app failed to load
when looking up commands. :issue:`2741`
- Add :meth:`sessions.SessionInterface.get_cookie_name` to allow
setting the session cookie name dynamically. :pr:`3369`
- Add :meth:`Config.from_file` to load config using arbitrary file
loaders, such as ``toml.load`` or ``json.load``.
:meth:`Config.from_json` is deprecated in favor of this. :pr:`3398`
- The ``flask run`` command will only defer errors on reload. Errors
present during the initial call will cause the server to exit with
the traceback immediately. :issue:`3431`
- :func:`send_file` raises a :exc:`ValueError` when passed an
:mod:`io` object in text mode. Previously, it would respond with
200 OK and an empty file. :issue:`3358`
- When using ad-hoc certificates, check for the cryptography library
instead of PyOpenSSL. :pr:`3492`
- When specifying a factory function with ``FLASK_APP``, keyword
argument can be passed. :issue:`3553`
- When loading a ``.env`` or ``.flaskenv`` file, the current working
directory is no longer changed to the location of the file.
:pr:`3560`
- When returning a ``(response, headers)`` tuple from a view, the
headers replace rather than extend existing headers on the response.
For example, this allows setting the ``Content-Type`` for
``jsonify()``. Use ``response.headers.extend()`` if extending is
desired. :issue:`3628`
- The ``Scaffold`` class provides a common API for the ``Flask`` and
``Blueprint`` classes. ``Blueprint`` information is stored in
attributes just like ``Flask``, rather than opaque lambda functions.
This is intended to improve consistency and maintainability.
:issue:`3215`
- Include ``samesite`` and ``secure`` options when removing the
session cookie. :pr:`3726`
- Support passing a ``pathlib.Path`` to ``static_folder``. :pr:`3579`
- ``send_file`` and ``send_from_directory`` are wrappers around the
implementations in ``werkzeug.utils``. :pr:`3828`
- Some ``send_file`` parameters have been renamed, the old names are
deprecated. ``attachment_filename`` is renamed to ``download_name``.
``cache_timeout`` is renamed to ``max_age``. ``add_etags`` is
renamed to ``etag``. :pr:`3828, 3883`
- ``send_file`` passes ``download_name`` even if
``as_attachment=False`` by using ``Content-Disposition: inline``.
:pr:`3828`
- ``send_file`` sets ``conditional=True`` and ``max_age=None`` by
default. ``Cache-Control`` is set to ``no-cache`` if ``max_age`` is
not set, otherwise ``public``. This tells browsers to validate
conditional requests instead of using a timed cache. :pr:`3828`
- ``helpers.safe_join`` is deprecated. Use
``werkzeug.utils.safe_join`` instead. :pr:`3828`
- The request context does route matching before opening the session.
This could allow a session interface to change behavior based on
``request.endpoint``. :issue:`3776`
- Use Jinja's implementation of the ``|tojson`` filter. :issue:`3881`
- Add route decorators for common HTTP methods. For example,
``app.post("/login")`` is a shortcut for
``app.route("/login", methods=["POST"])``. :pr:`3907`
- Support async views, error handlers, before and after request, and
teardown functions. :pr:`3412`
- Support nesting blueprints. :issue:`593, 1548`, :pr:`3923`
- Set the default encoding to "UTF-8" when loading ``.env`` and
``.flaskenv`` files to allow to use non-ASCII characters. :issue:`3931`
- ``flask shell`` sets up tab and history completion like the default
``python`` shell if ``readline`` is installed. :issue:`3941`
- ``helpers.total_seconds()`` is deprecated. Use
``timedelta.total_seconds()`` instead. :pr:`3962`
- Add type hinting. :pr:`3973`.
