+  * Use the linux-g++ mkspec on all Linux architectures. We do not need
+    the -m64 compiler flag which linux-g++-64 adds.
+  * Split qmake binary into a new binary package, qt5-qmake-bin.
+    Make the new package Multi-Arch: foreign, to make sure that a proper
+    version of qmake gets installed for cross builds (closes: #876861).
+  * Bump Standards-Version to 4.1.1, no changes needed.
