Flask: Ending Python 2 Support

[NewsBot]

A new Flask blog post/announcement has been posted!

Upstream support for Python 2.7 is ending on January 1, 2020. Pallets is joining the community of open source projects ending support for Python 2 at that time. Our statement and support plan are based on PyTest's announcement.

We will be dropping support for Python 2.7 as well as Python 3.5 and below, as their support windows have ended or will end around the same time. Future releases of each Pallets project will only support Python versions still supported upstream, which can be found in the Python Developer's Guide.

The last version branch of each core project to support Python 2.7 and Python 3.5 are:

• Flask 1.1.x
• Werkzeug 1.0.x
• Click 7.x
• Jinja 2.11.x
• ItsDangerous 1.1.x
