Hello, i need more shader setup for the shader like in Cubicity tutorial. 
yeah the node changed in the latest Blender release. I know Martin has an image where he details the changes and he'll probably upload it here. But I would like to make the case for using the Blender version Kent uses in Cubicity instead. Much other things have changed, not only the node, so you'll be struggling with that throughout the course, so it is much better to learn with the Blender version Kent uses, it's not a big deal, it's just buttons and UI changes, all the core knowledge is 100% the same. You will have a better experience of the course with you match the Blender version, believe me.
Sorry I'm not very good in English. If I understand correctly, you advise me to launch a previous version of blender?
I don't know if you use DeepL, but it's a great resource for translation:

But yeah, a previous Blender version, specifically the one Kent is using in the course, so that your Blender and the Blender in the video match.
Yeah, use the version from the course (3.2) or 3.3 LTS. Especially if you plan to make Assets to be included in the library. Models made in 3.4+ will not be accepted, because they won't be usable; 3.4 is not backwards compatible.
But if you want to know: Specular has been renamed to IOR Level and is found under Specular. Roughness is still Roughness (just below Metallic).
