Flask 2.0

Flask 2.0 has just been released. Along with it come many other major satellite releases: Werkzeug 2.0, Jinja 3.0, Click 8.0, ItsDangerous 2.0, and MarkupSafe 2.0.

Across all projects, Python 3.6+ is now required, and comprehensive type annotations are supported. At a glance, I’d say that the biggest news is async views in Flask 2. Work has also been done around Werkzeug Request and Response classes to allow for better sync and async in the future (it’s not a public API yet.) Jinja, Click and ItsDangerous come with a lot of new niceties. Details are available on the Pallets website.

Flask is, of course, the giant on which shoulders the whole Eve project rests. To say that the Pallets team has been working hard at the forge is an understatement—huge congrats to all of them.
