Lesson 6, FLASK_ENV is removed from Flask 2.3.0

In lesson 6 the code suggests enabling debugging by setting FLASK_ENV=development.
This does not work since the environment variable FLASK_ENV is removed from Flask version 2.3.0.
The new way to enable debugging is to set the environment variable:
FLASK_DEBUG=True
The new way
The new old way is how I would call it. :)
The FLASK_DEBUG variable was the way to do this in the 0.x and 1.x versions of Flask. The Flask Mega-Tutorial made use of it. At some point they decided that FLASK_ENV was better. The Flask Mega-Tutorial was updated to reflect their thinking. Now they decided that FLASK_DEBUG is actually better and not worse, and removed FLASK_ENV. I really try to not be frustrated by all the breakage these people generate with this and many other silly changes like it, but it is really hard not to be! They continue putting out releases with no substantive changes, just renames and removals.
Closing as this does not apply to the new edition of this tutorial.
