ESLint v8.3.0 released

Highlights

This release supports ES2022 class static blocks in rules, the default parser, and scope analysis.

class C {
    static x = ...;
    static y;
    static z;
    static {
        try {
            const obj = doSomethingWith(this.x);
            this.y = obj.y;
            this.z = obj.z;
        }
        catch {
            this.y = ...;
            this.z = ...;
        }
    }
}

It also supports #x in obj, officially known as ergonomic brand checks for private fields.
