@ -369,3 +369,10 @@ Changes made since CMake 3.15.0 include the following.
* In CMake 3.15.0 and 3.15.1 the :variable:`CMAKE_FIND_PACKAGE_PREFER_CONFIG`
variable caused the :command:`find_package` command to fail on a missing
package even without the ``REQUIRED`` option. This has been fixed.
3.15.3
------
* ``CrayPrgEnv`` compiler wrapper support has been updated for the 19.06
release of the Cray Programming Environment for which the default linking
mode on XC Cray systems is now dynamic instead of static.
