Man, I just got through changing all my computers over to 5.8.8 and they have released a new version. 

• The BOINC Manager offers two different interfaces: 'Simple' (small, graphical, skinnable) and 'Advanced' (maximum information). The Simple GUI allows local editing of preferences. You can switch back and forth between Simple and Advanced.
• CPU throttling: you can reduce CPU heat by limiting the fraction of time that BOINC computes.
• Improved scheduling policies avoid missing job deadlines even on a slow computer with lots of projects.
• You can limit the amount of memory used by BOINC; this lets you compute all the time without losing performance.
• Mac OS X version runs applications in an unpriviledged account, increasing security.
• Snooze button (in the system tray icon) lets you stop computing for one hour.

The DCF is fixed so if you keep a queue it is pretty important. The *nix version seems to be working at docking@home now. A bug where BOINC would think a task was running when it was not seems to be fixed. So it's pretty imprortant overall, although not quite as important as getting to .8 was.
