Chris,

I am sorry to repeat myself, but the changelog is quite verbose with 
respect to "what is being done", but it doesn't contain any information 
whatsoever with respect to "why is this an improvement over current 
state", IOW why we are changing the status quo at all.

This absolutely has to be present in the changelog.

Thanks,
