[dependabot]

Bumps flask from 0.12.4 to 1.0.

Release notes

Sourced from flask's releases.

1.0

The Pallets team is pleased to release Flask 1.0. [Read the announcement on our blog.](https://www.palletsprojects.com/blog/flask-1-0-released/

There are over a year's worth of changes in this release. Many features have been improved or changed. Read the changelog to understand how your project's code will be affected.

JSON Security Fix

Flask previously decoded incoming JSON bytes using the content type of the request. Although JSON should only be encoded as UTF-8, Flask was more lenient. However, Python includes non-text related encodings that could result in unexpected memory use by a request.

Flask will now detect the encoding of incoming JSON data as one of the supported UTF encodings, and will not allow arbitrary encodings from the request.

Install or Upgrade

Install from PyPI with pip:

pip install -U Flask

Version 1.0

Released 2018-04-26

• Python 2.6 and 3.3 are no longer supported.
• Bump minimum dependency versions to the latest stable versions:
  Werkzeug >= 0.14, Jinja >= 2.10, itsdangerous >= 0.24, Click >= 5.1.
  :issue:2586
• Skip :meth:app.run <Flask.run> when a Flask application is run
  from the command line. This avoids some behavior that was confusing
  to debug.
• Change the default for :data:JSONIFY_PRETTYPRINT_REGULAR to
  False. :func:~json.jsonify returns a compact format by
  default, and an indented format in debug mode. :pr:2193
• :meth:Flask.__init__ <Flask> accepts the host_matching
  argument and sets it on :attr:~Flask.url_map. :issue:1559
• :meth:Flask.__init__ <Flask> accepts the static_host argument
  and passes it as the host argument when defining the static
  route. :issue:1559
• :func:send_file supports Unicode in attachment_filename.
  :pr:2223
• Pass _scheme argument from :func:url_for to
  :meth:~Flask.handle_url_build_error. :pr:2017
• :meth:~Flask.add_url_rule accepts the
  provide_automatic_options argument to disable adding the
  OPTIONS method. :pr:1489
• :class:~views.MethodView subclasses inherit method handlers from
  base classes. :pr:1936
• Errors caused while opening the session at the beginning of the
  request are handled by the app's error handlers. :pr:2254
• Blueprints gained :attr:~Blueprint.json_encoder and
  :attr:~Blueprint.json_decoder attributes to override the app's
  encoder and decoder. :pr:1898
• :meth:Flask.make_response raises TypeError instead of
  ValueError for bad response types. The error messages have been
  improved to describe why the type is invalid. :pr:2256
• Add routes CLI command to output routes registered on the
  application. :pr:2259
• Show warning when session cookie domain is a bare hostname or an IP
  address, as these may not behave properly in some browsers, such as
  Chrome. :pr:2282
• Allow IP address as exact session cookie domain. :pr:2282
• SESSION_COOKIE_DOMAIN is set if it is detected through
  SERVER_NAME. :pr:2282
• Auto-detect zero-argument app factory called create_app or
  make_app from FLASK_APP. :pr:2297
• Factory functions are not required to take a script_info
  parameter to work with the flask command. If they take a single
  parameter or a parameter named script_info, the

Looks like flask is up-to-date now, so this is no longer needed.
