 ### Added
+* PermutationFullUnaryOperator and PermutationFullBinaryOperator functional interfaces for the purpose
+  of specifying custom operations on Permutation objects. These are variations of the existing
+  PermutationUnaryOperator and PermutationBinaryOperator interfaces that were added in 3.2.0, but with 
+  both the raw int arrays and Permutation objects passed to the operators.
+* Permutation.apply methods, one for each of the two new PermutationFullUnaryOperator 
+  and PermutationFullBinaryOperator interfaces, for applying such custom Permutation operators.
