http://bubba/admin/settings/software currently reports squeezecenter 7.5.1.dfsg1-5.
However, http://bubba:9000/ reports, at the bottom of the page, a new available version 7.5.1.
1. Is 7.5.1 newer than 7.5.1.dfsg1-5?

2. Should I best rely on the Bubba system update, or am I supposed to update squeezebox server manualy?
