   CAUTION: All default values are lost! If you have built a circuit that contains
            test cases that depend on a non-null default value, this tests will fail. To
            resolve this issue, reset the default value.
-- added an enable input to the T flip-flop
+- Added an enable input to the T flip-flop
   CAUTION: By default this input is activated now. In circuits which used the T flip-flop
            in the past, the new input needs to be disabled.
 - A warning message shows up if a circuit with unnamed inputs is analysed.
