Messages After Updating

Good Time of Day:

After updating and Debian-Goodies telling me which services need to be
restarted, I've always been puzzled by these messages:

Debian-gdm on /dev/tty7 is running obsolete gnome-session-b[785],
gnome-settings-[1015], gnome-shell[794]
stephen on /dev/tty2 is running obsolete blueman-applet[1316],

Does this mean that the above need to be restarted, therefore one should
logout and back in? The term 'obsolete' confuses this user.
