I used to do this on an ad-hoc basis: the nightly builds at MSR spit out
nofib results that I compared against previous releases.
In practice you want to do this much earlier than just before a release,
because it can take time to investigate and squash any discrepancies.
On the subject of the release process, I believe Ian has a checklist
that he keeps promising to put on the wiki (nudge :)).
