Is Sparkle otherwise stable?  My main concern is a big Sparkle upgrade right as we push out a huge update (1.4); some unforeseen problem could be a huge headache.  On the other hand, if everything else is okay, we can get the new Sparkle in, continue to use the old update methods, test delta updating in a beta series, and start using it in the release series if successful.
