so nothing to fix Hal's find?
No, that will be fixed in the 0.8 release.If you think the single-send-not-randomizing-the-change-address-bug gives you significantly less privacy... well, you're probably wrong, it is easy to cluster addresses if you have the right network analysis tools. But you can workaround the bug by adding an extra output to all of your transactions (add a new receiving address and then click the 'add recipient' button in on the Send Coins tab in Bitcoin-Qt and send some coins to yourself).
