       the platform don't support supplementary groups concept.

+  * bigdecimal
+    * Kernel.BigDecimal and BigDecimal.new now accept instances of Integer,
+      Rational, and Float.  If you pass a Rational or a Float to them, you must
+      specify the precision to produce the digits of a BigDecimal.
+
+    * The behavior of BigDecimal#coerce with a Rational is changed.  It uses
+      the precision of the receiver BigDecimal to produce the digits of a
+      BigDecimal from the given Rational.

 * io/console
   * new methods:
     * IO#noecho {|io| }
