+       New: For recognizing a diverging solver before the maximum
+       number of steps is reached, <code
+       class="class">SolverControl</code> returns <code
+       class="member">failure</code> also if the residual increases
+       the start residual by a specific factor. This factor is given
+       to the <code class="class">SolverControl</code> by the <code
+       class="member">set_failure_criterion</code> function. After
+       calling the latter function the checking of this additional
+       failure criterion may again be disabled by calling <code
+       class="member">clear_failure_criterion</code>.

        Improved: The interface of preconditioner classes has changed.
        Preconditioners are now considered linear operators like

+       New: The new function <code class="member">get_face</code>
+       of <code class="class">FEFaceValues</code> and <code
+       class="class">FESubfaceValues</code> returns an iterator of the
+       present face. This is the face, for that the <code
+       class="class">FE(Sub)FaceValues</code> object was reinited
+       the last time.

        New: classes <code class="class">FEDG_Px</code> implement
        complete polynomial spaces of degree <em>x</em> on
        still incomplete.
