 == Changes since the 2.0.0 release
 
 === Language changes
+
+* Added integer and float literals: 'r', 'i', and 'ri'.
+  * "42r" and "3.14r" are evaluated as Rational(42, 1) and 3.14.rationalize,
+    respectively.  But exponential form with 'r' suffix like "6.022e+23r" is
+    not accepted bcause it is misleadable.
+  * "42i" and "3.14i" are evaluated as Complex(0, 1) and Complex(0, 1.5),
+    respectively.
+  * "42ri" and "3.14ri" are evaluated as Complex(0, 42r) and Complex(0, 3.14r),
+    respectively.

 === Core classes updates (outstanding ones only)
