2D Sprite Shape is out of preview for 2019.3

Unity Engine

Hello, I’m looking for an old version that had isDirty exposed:

public bool isDirty
        {
            set
            {
                this.m_isDirty = value;
            }
        }

SpriteShape Preview Package page-1

Does anyone know where can I find it? I have my reasons trust me.

Also, where is SpriteShapeRenderer? It was part of SpriteShapeModule/UnityEngine.U2D
