Thanks; we really ought to do a parallel release of binaries with 0.4.0, and maybe keep it up until the core dev team finally merges it.
I think everybody would like to merge bitcoin-qt as soon as the 0.4 release is shipped (see the bitcoin-dev mailing list for the current known bugs).
Closing the dozens of wxWidgets-related GUI bugs in the issues list will give me great pleasure...
Doesn't bitcoin-qt already contain the 0.4 core? If yes, what is the reason to even release bitcoin 0.4? Why not release 0.4-qt instead?
