+FetchContent
+------------
+
+* A new :module:`FetchContent` module was added which supports populating
+  content at configure time using any of the download/update methods
+  supported by :command:`ExternalProject_Add`.  This allows the content
+  to be used immediately during the configure stage, such as with
+  :command:`add_subdirectory`, etc.  Hierarchical project structures are
+  well supported, allowing parent projects to override the content details
+  of child projects and ensuring content is not populated multiple times
+  throughout the whole project tree.
