Changelog

Sourced from flask's changelog.

Version 2.0.3

Released 2022-02-14

• The test client's as_tuple parameter is deprecated and will be removed in Werkzeug 2.1. It is now also deprecated in Flask, to be removed in Flask 2.1, while remaining compatible with both in 2.0.x. Use response.request.environ instead. :pr:4341
• Fix type annotation for errorhandler decorator. :issue:4295
• Revert a change to the CLI that caused it to hide ImportError tracebacks when importing the application. :issue:4307
• app.json_encoder and json_decoder are only passed to dumps and loads if they have custom behavior. This improves performance, mainly on PyPy. :issue:4349
• Clearer error message when after_this_request is used outside a request context. :issue:4333

Closing for #7116

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
