Yes! All recipes are made using Godot Engine 4.0.
I highly recommend you trying to apply the knowledge from GDQuest on newer versions of Godot. If I'm correct, they will update their courses to Godot Engine 4.0 anyway.
Tho, besides breaking changes, the changes are interchangeable. We can go through the process of applying the recipes from the book into 3.5 if you're willing to. We can do that gradually through Discord :D
