As far as 4a14f13a0 goes, I would think that ought to be mentioned under
"Source Code" since it's a change in a rather widely used API. I doubt
that the performance aspect of it is really all that exciting to end
users, but third-party modules calling the dynahash code would care.
The hash join changes are a completely different thing.
