That's not how we reference upstream commits. I had to search the git log the hard 
way to figure out that it's commit d9345c65eb79 ...

Also, once you look at that commit you'll see how sloppy the capitalization in 
your changelog is. I fixed that up for all the original commits in the hope of you 
learning from those mistakes - but that was last year and the experiment failed.

Thanks,
