Change log below the --- 

We don't want it in the permanent git history.  There will
be a link tag to this thread to allow anyone who happens to 
want to known more to find the version change log.

Given you got it right in the other 3 patches, I'm guessing you
just missed here.

If that is all that turns up in review, I can fix it whilst applying.

Thanks,

Jonathan
