Have any changes ever been made to article 3 of the united states constitution?

No there has not been any changes. "Note: Article III, section 2, of the Constitution was modified by amendment 11. The Judicial power of the United States shall not be construed to extend to any suit in law or equity, commenced or prosecuted against one of the United States by Citizens of another State, or by Citizens or Subjects of any Foreign State."
