Hi Ezo @kleelo ,
It depends on what you consider ‘compatible’; the modeling techniques taught here are still the same in 4.3, but the UI is very different.
I’d recommend you follow along with Blender 2.79, although that might seem unintuitive.
Alternatively, you can take the latest Fundamentals of Mesh Modeling: https://cgcookie.com/courses/core-fundamentals-mesh-modeling
That was made with Blender 4.2.
