Hello Coders!

In October 2021 [Flask Version 2.0.2](https://flask.palletsprojects.com/en/2.0.x/changes/) has been released with various upgrades to the framework, improvements, and deprecations. This article is a quick overview of Flask 2.x update.

> Thanks for reading!

## ✨ Flask 2.x Updates

> `Blueprints`

Starting with `2.0` version `Blueprints` can be nested under each other. This feature might improve the design of complex products.

---

> `Config from file`

Re-add deprecated `Config.from_json`, which was accidentally removed early.

---

> `Improved CLI errors`

When an app could not be loaded, errors are displayed instantly when the development server is active.

---

> `FLASK_DEBUG` is deprecated

Replaced by `FLASK_ENV`, a more current environment variable.

---

> `Language Detection`

`langdetect` package is used by default.

---

> `Improved Static files cache` - on development

Browsers will cache static files based on file content rather than a 12-hour refresh time frame.

---

> `Blueprints`

Can be registered the same blueprint with different names
