+  Comparing instances of :class:`Decimal` with floating-point
+  numbers now produces sensible results based on the numeric values
+  of the operands.  Previously such comparisons would fall back to
+  Python's default rules for comparing objects, which produced arbitrary
+  results based on their type.  Note that you still cannot combine
+  :class:`Decimal` and floating-point in other operations such as addition,
+  since you should be explicitly choosing how to convert between float and
+  :class:`Decimal`.
+  (Fixed by Mark Dickinson; :issue:`2531`.)
+
   Most of the methods of the :class:`~decimal.Context` class now accept integers
   as well as :class:`~decimal.Decimal` instances; the only exceptions are the
