Review Comment:
   I don't mean the whole comment... most of the comment is fine... I just 
don't think it's useful to hard-code the version numbers into the comment, 
because that's not really adding anything that the rest of the comment doesn't 
already have... but by hard-coding these version names into the comment, it is 
making it more that we have to change when we move forward, in order to keep 
the comment current. I just think that's creating unnecessary work for 
ourselves, and in this case, I don't think it makes it any more clear than what 
was there before.
