Release notes for a new version are not the place to list all the features of the engine. You can literally click on the home page and see "Object-oriented API with language options such as GDScript, C#, C++ and visual scripting.".
If people give up "in disgust" because they can't find what language the engine uses for scripting immediately in the first sentence of a release announcement then they're probably not cut out for making any kind of software which requires digging through documentation.
