+
+  This macro can be defined in the project file to disable functions deprecated in
+  a specified version of Qt or any earlier version. The default version number is 5.0,
+  meaning that functions deprecated in or before Qt 5.0 will not be included.
+
+  Examples:
+  When using a future release of Qt 5, set QT_DISABLE_DEPRECATED_BEFORE=0x050100 to
+  disable functions deprecated in Qt 5.1 and earlier. In any release, set
+  QT_DISABLE_DEPRECATED_BEFORE=0x000000 to enable any functions, including the ones
+  deprecated in Qt 5.0

+
+  QRefCount implements atomic ref counting for Qt's shared classes. It behaves very similar
+  to QAtomicInt, but ignores negative ref counts.
+
+  This can be used to allow to implement e.g. const read-only QStringData objects. QString::shared_null and
+  the qs(...) macro make use of this feature.
