 release. If you rely on this, your code is probably unnecessarily slow. Let us
 know if the removal would create a problem for you.

 #  ML_ADMConstraints: There seems to be a problem regarding calculating the
    constraints from the BSSN quantities. The exact problem is not known yet,
    but indications point towards a compiler problem (Intel in all cases).
+   In all cases the metric data (evolved with ML_BSSN) is identical to the test
+   data (to round-off error) and only the ML_ADMConstraints data differ
+   significantly from the test data. If output statements of relevant
+   quantities are inserted into the code, the differences disappear
    One consistent symptom is failing of the Dissipation and RotatingSymmetry
    testsuites (as they include output of the constraints using
    ML_ADMConstraints). Investigations on this matter will continue,
