After living there for ten years and being here for three, I'm not sure of any changes but I'll do my best.
No "duty" to inform but if you are stopped do it as a courtesy to the officer, you don't have to use the "I'm a Jew" (by law, sir, I am required to inform you I am a Jew (carrying a firearm)) line but just hand them your DL, Reg, Insurance and, CCW. It will actually make the stop smother, in case they spot your weapon.
Other than that go wherever, do whatever, with obvious exceptions courthouse, Don's Guns, any place that you may find that is actually posted.
But what do I know, I'm just a high school educated security officer.
