+    \class QOperatingSystemVersion
+    \inmodule QtCore
+    \since 5.9
+    \brief The QOperatingSystemVersion class provides information about the
+    operating system version.
+
+    Unlike other version functions in QSysInfo, QOperatingSystemVersion provides
+    access to the full version number that \a developers typically use to vary
+    behavior or determine whether to enable APIs or features based on the
+    operating system version (as opposed to the kernel version number or
+    marketing version).
+
+    This class is also a complete replacement for QSysInfo::macVersion and
+    QSysInfo::windowsVersion, additionally providing access to the third (micro)
+    version number component.
+
+    Presently, Android, Apple Platforms (iOS, macOS, tvOS, and watchOS),
+    and Windows are supported.
+
+    The \a majorVersion(), \a minorVersion(), and \a microVersion() functions
+    return the parts of the operating system version number based on:
+
+    \table
+        \header
+            \li Platforms
+            \li Value
+        \row
+            \li Android
+            \li result of parsing
+                \l{https://developer.android.com/reference/android/os/Build.VERSION.html#RELEASE}{android.os.Build.VERSION.RELEASE}
+                using QVersionNumber, with a fallback to
+                \l{https://developer.android.com/reference/android/os/Build.VERSION.html#SDK_INT}{android.os.Build.VERSION.SDK_INT}
+                to determine the major and minor version component if the former
+                fails
+        \row
+            \li Apple Platforms
+            \li majorVersion, minorVersion, and patchVersion from
+                \l{https://developer.apple.com/reference/foundation/nsprocessinfo/1410906-operatingsystemversion?language=objc}{NSProcessInfo.operatingSystemVersion}
+        \row
+            \li Windows
+            \li dwMajorVersion, dwMinorVersion, and dwBuildNumber from
+                \l{https://msdn.microsoft.com/en-us/library/mt723418.aspx}{RtlGetVersion} -
+                note that this function ALWAYS return the version number of the
+                underlying operating system, as opposed to the shim underneath
+                GetVersionEx that hides the real version number if the
+                application is not manifested for that version of the OS
+    \endtable
+
+    Because QOperatingSystemVersion stores both a version number and an OS type, the OS type
+    can be taken into account when performing comparisons. For example, on a macOS system running
+    macOS Sierra (v10.12), the following expression will return \c false even though the
+    major version number component of the object on the left hand side of the expression (10) is
+    greater than that of the object on the right (9):
+
+    \snippet code/src_corelib_global_qoperatingsystemversion.cpp 0
+
+    This allows expressions for multiple operating systems to be joined with a logical OR operator
+    and still work as expected. For example:
+
+    \snippet code/src_corelib_global_qoperatingsystemversion.cpp 1
+
+    A more naive comparison algorithm might incorrectly return true on all versions of macOS,
+    including Mac OS 9. This behavior is achieved by overloading the comparison operators to return
+    \c false whenever the OS types of the QOperatingSystemVersion instances being compared do not
+    match. Be aware that due to this it can be the case \c x >= y and \c x < y are BOTH \c false
+    for the same instances of \c x and \c y.
