Cos'è la "escrow"? E' la fase che precede la RTM, e che serve a
verificare che sia tutto ok...
As you can tell from the cadence of releases and information coming
out, TFS 2005 is getting pretty close to shipping. We've entered what we
call "escrow". That means we think we've fixed everything we need
to fix and are performing our final full test pass to ensure that there
haven't been any new bugs introduced recently or any critical things we have
missed.
