+ ** Integer formats used in the printf family of functions now work for
+    64-bit integers and are more compatible with Matlab when printing
+    non-integer values.  Now instead of truncating, Octave will switch
+    the effective format to '%g' in the following circumstances:
+
+      * the value of an integer type (int8, uint32, etc.) value exceeds
+        the maximum for the format specifier.  For '%d', the limit is
+        intmax ('int64') and for '%u' it is intmax ('uint64').
+
+      * round(x) != x or the value is outside the range allowed by the
+        integer format specifier.
+
+    There is still one difference:  Matlab switches to '%e' and Octave
+    is currently switching to '%g'.
