<Formletter>  
Change log goes here. If it is missing, I won't know what changed.
That means I will have to dig out older patch versions to compare.
That costs time and would hold up both this patch as well as all other
patches which I still have to review.

For this reason, I will not review patches without change log.

As before, the change log is small and recent enough that I remember,
so you are lucky.

Thanks,
