   program outputs are typically probabilistic and statistics produced by measurement processes are
   conditional on the selected decision tree path.
 
+* Two new verifiers were added to the `quantum.paulirot` operation. They verify that the Pauli word
+  length and the number of qubit operands are the same, and that all of the Pauli words are legal.
