+
+    The \\sincelist command expands to a detailed breakdown of new
+    inclusions to the documented API in a specified version. Example
+    usage:
+
+    \badcode * \QtMajorVersion \QtMinorVersion \QtVer
+    /\1!
+       \page newclasses\2\3.html
+       \title New Classes and Functions in \4
+       \brief A comprehensive list of new classes and functions in \4.
+
+       \sincelist \4
+    \1/
+    \endcode
+
+    \\sincelist takes a single argument, a version string. The generated
+    output includes all functionality that is marked with a
+    \l {since-command}{\\since} command or a \l {since clause} matching
+    the version string.
