+- Update to version 2.31.18:
+  + GDBusProxy has now a flag,
+    G_DBUS_PROXY_FLAGS_GET_INVALIDATED_PROPERTIES, which can be set
+    to make GDBus automatically reload changed properties even if
+    the propertychanged signal does not contain the new values.
+  + GApplication puts non-unique applications on the bus
+  + GApplication now has g_application_quit()
+  + g_async_queue_timed_pop has been deprecated in favor of the new
+    g_async_queue_timeout_pop, which uses relative delays in
+    microseconds instead of a GTimeVal.
+  + Huge number of API documentation fixes
+  + Bugs fixed: bgo#647986, bgo#658484, bgo#664237, bgo#669329,
+    bgo#669330, bgo#669372, bgo#669412, bgo#669538, bgo#669544,
+    bgo#669595, bgo#669670, bgo#669671, bgo#669689, bgo#669810,
+    bgo#669865, bgo#670085, bgo#670138, bgo#670485.
+  + Updated translations.
+- Remove xz BuildRequires now that it comes for free in the build
+  system.
