Shouldn't be to hard, there are numerous hooks that could be used either
on the developer end (post-commit), on the server end (post-update) or
even when a maintainer applies a patch (post-applypatch). See
githooks(5) for more info on what hooks are available and what args are
passed.
There is also the possibility of generating this changelog at the time
of release. I'd advocate this approach as it would allow you to edit the
changelog to make it more useful to readers.
Either way the actual format could probably be generated with 'git log
--format' (someone else may reply with better plumbing commands, but my
initial response is use git log).
My 2 minutes worth of reading git-log(1) got me this
git log --format="%ai%x09%an <%ae> %n%x09* %s" REVISIONS
Which for a chunk of gits pu branch gave me this (my mail client munges
some of the longer lines)

* Introduce CHERRY_PICK_HEAD
Which is pretty close. You could experiment with more format specifiers
to get the info you need.
Hope that helps
