Changelog

Sourced from flask's changelog.

Version 1.1.2

Released 2020-04-03

• Work around an issue when running the flask command with an external debugger on Windows. :issue:3297
• The static route will not catch all URLs if the Flask static_folder argument ends with a slash. :issue:3452

Version 1.1.1

Released 2019-07-08

• The flask.json_available flag was added back for compatibility with some extensions. It will raise a deprecation warning when used, and will be removed in version 2.0.0. :issue:3288

Version 1.1.0

Released 2019-07-04

• Bump minimum Werkzeug version to >= 0.15.

• Drop support for Python 3.4.

• Error handlers for InternalServerError or 500 will always be passed an instance of InternalServerError. If they are invoked due to an unhandled exception, that original exception is now available as e.original_exception rather than being passed directly to the handler. The same is true if the handler is for the base HTTPException. This makes error handler behavior more consistent. :pr:3266

  • :meth:Flask.finalize_request is called for all unhandled exceptions even if there is no 500 error handler.

• :attr:Flask.logger takes the same name as :attr:Flask.name (the value passed as Flask(import_name). This reverts 1.0's behavior of always logging to "flask.app", in order to support multiple apps in the same process. A warning will be shown if old configuration is detected that needs to be moved. :issue:2866

• :meth:flask.RequestContext.copy includes the current session object in the request context copy. This prevents session pointing to an out-of-date object. :issue:2935

• Using built-in RequestContext, unprintable Unicode characters in Host header will result in a HTTP 400 response and not HTTP 500 as
