+ * Function:    H5Fset_latest_format
+ *
+ * Purpose:     Enable switching between latest or non-latest format while
+ *              a file is open.
+ *              This is deprecated starting release 1.10.2 and is modified
+ *              to call the private H5F_set_libver_bounds() to set the
+ *              bounds.
+ *
+ *              Before release 1.10.2, the library supports only two
+ *              combinations of low/high bounds: 
+ *                  (earliest, latest)
+ *                  (latest, latest)
+ *              Thus, this public routine does the job in switching 
+ *              between the two combinations listed above.
+ *
+ *              Starting release 1.10.2, we add v18 to the enumerated
+ *              define H5F_libver_t and the library supports five combinations
+ *              as below:
+ *                  (earliest, v18)
+ *                  (earliest, v10)
+ *                  (v18, v18)
+ *                  (v18, v10)
+ *                  (v10, v10)
+ *              So we introduce the new public routine H5Fset_libver_bounds()
+ *              in place of H5Fset_latest_format().
+ *              See also RFC: Setting Bounds for Object Creation in HDF5 1.10.0.
+ *
+ * Return:      Non-negative on success/Negative on failure
+ *
+ * Programmer:  Vailin Choi; December 2017
