+- Conditionally apply translations-update-upstream BuildRequires
+  and macro for non-openSUSE only.
+- Change gnome-session-ice-auth-for-suid.patch patch tag to
+  PATCH-FIX-SLE, and only apply for non-opensuse. Same for
+  gnome-common BuildRequires and NOCONFIGURE call.
+- Add xsltproc BuildRequries: Needed for man pages, pulled in by
+  gnome-common before.
+- Drop no longer needed Provides and Obsoletes: gnome-core,
+  gnome-session-branding, gnome-session-gtk1-support,
+  gnome-session-splash, gnome-session-fallback-session and
+  gnome2-look-and-feel.
+- Drop hicolor-icon-theme BuildRequires: We rely on Adwaita now,
+  and that is always provided by gtk3.
