+  *) --strict-warnings no longer enables runtime debugging options
+     such as REF_DEBUG. Instead, debug options are automatically
+     enabled with '--debug' builds.

   *) Made DH and DH_METHOD opaque. The structures for managing DH objects
      have been moved out of the public header files. New functions for managing
      these have been added.
