  Changes between 1.1.1 and 1.1.2 [xx XXX xxxx]
 
+  *) Recreate the OS390-Unix config target.  It no longer relies on a
+     special script like it did for OpenSSL pre-1.1.0.
+     [Richard Levitte]
+
   *) Instead of having the source directories listed in Configure, add
      a 'build.info' keyword SUBDIRS to indicate what sub-directories to
      look into.
