Did Unity 4 change Mesh.uv?

[fanling3]

I have recently upgraded Unity from 3.5.0 to 4.1.2
I had script changing uv for frame animation, like:

Vecto2[] uvs = new Vector2[] {
    new Vector2(0, 0),
    new Vector2(0.5f, 0),
    new Vector2(0, 0.5f),
    new Vector2(0.5f, 0.5f)
}

mesh.uv = uvs;

sure my original code are variables instead of 0 and 0.5.
After I upgraded to 4.1.2 all textures displayed are abnormal, like misplacing uv coordinates. Anyone have ideas?

I changed the order and it works fine

Vecto2[] uvs = new Vector2[] {
    new Vector2(0, 0),
    new Vector2(0.5f, 0.5f),
    new Vector2(0.5f, 0),
    new Vector2(0, 0.5f)      
}
     
mesh.uv = uvs;
