New vs old N150

[Camoman1]

I read that VV updated their formula to be more temp stable, any one know when this happened and if anyone knows how the new preforms vs the old?

I asked a vihtavuori rep this a few years ago, and he stated that it is not a change and has always been temperature stable. According to him, only the anti-coppering agent is new. My experience is that N150, while not the most temperature sensitive, is no way comparable to the Hodgdon Extreme powders in this regard.
