Riiiigggghhhhttt. What was special about 132, here are a couple of key verses in the introductions where 'god' is addressing Smith and this doctrine:
4 For behold, I reveal unto you a new and an everlasting covenant; and if ye abide not that covenant, then are ye damned; for no one can reject this covenant and be permitted to enter into my glory.
6 And as pertaining to the new and everlasting covenant, it was instituted for the fulness of my glory; and he that receiveth a fulness thereof must and shall abide the law, or he shall be damned, saith the Lord God.
Soooo, an EVERLASTING covenant that if you don't abide in it results in damnation can change from time to time. How is this so if the prophet is 'inspired' by god.
The covenant, once made, is everlasting. That's the meaning of it.
What it does not mean is that the same covenant will always be required of His people. All Bible-believing Christians already know this, as the old covenant was done away with the crucifixion of Christ. Afterward, there was a new covenant; a change.
