     Notes
     -----
     The return type for 2D arrays depends on the default class set for
     state space operations.  See :func:`~control.use_numpy_matrix`.
 
-    The return type for `E` differs from the equivalent return values in the
-    :func:`~control.lqr`, :func:`~control.care`, and other similar
-    functions.  The return type will be changed to a 1D array in a future
-    release.

     Examples
     --------
     >>> K, P, E = lqe(A, G, C, QN, RN)
