+Updates
+=======

+3.11.1
+------
+
+* The :module:`CheckIncludeFile` module ``check_include_file`` macro,
+  :module:`CheckIncludeFileCXX` module ``check_include_file_cxx`` macro,
+  and :module:`CheckIncludeFiles` module ``check_include_files`` macro
+  were taught to honor the ``CMAKE_REQUIRED_LIBRARIES`` variable in
+  CMake 3.11.0.  This has been reverted due to changing behavior of
+  checks for existing projects.  It may be restored in the future
+  with a policy for compatibility.
