"This release debuts full support for fast user switching, a
long-requested feature that makes the networking experience on
multi-user computers butter-smooth. As a result of the simplified
0.9 architecture, each user gets their own network applet and each
applet can control networking independently, provided that user has
permissions to do so.
If you switch and the new active user doesn't have permissions
for a connection, it's terminated. It's as simple as that and works
just like you'd expect.
