Flask 2.0 Is Coming, Please Help Us Test

Hello,

Flask 2.0 is due for release soon, with a release candidate 2.0.0rc1 available now on PyPI. Please try this out and let us know if there are any issues.

pip install --pre flask

This major release of Flask is accompanied by major releases of Werkzeug, Jinja2, click, and itsdangerous which we’d also welcome and appreciate testing (their pre releases are installed with the Flask pre release).

Some highlights from Flask’s Changelog,

• Support Python 3.6+ (dropping Python 2.7 and 3.5 support)
• Deprecate a number of features (see details).
• Initial async-await support (optional install flask[async]), that allows for async route handlers, errorhandlers, before/after request, and teardown functions.
• Short form route decorators e.g. @app.get, @app.post, etc…
• Nested blueprints, blueprint.register_blueprint(another_blueprint).
• Much more! (Please ask)
