The inclusion of the "%{release}" makro in the "Provides" / "Obsoletes" fields of the package metadata means that on each and every rebuild there's a diff to the previous build and the new build is published even when there are no real changes. That causes quite some "noise" for me with SuSE Manager quite often telling me I had updates to approve of. I'm not exactly sure if %{version} wouldn't be sufficient but I thought I could at least give a heads up here ...
