This resulted in doing more work than was actually +necessary, and this has been rectified. On the other hand, this change +means that in some circumstances, codes may not have explicitly +told an FEValues or FEFaceValues object that they actually need the +JxW values, but could access them anyway without getting an +error. This will now yield an error that is easily fixed by +explicitly listing update_JxW_values as a required flag where you +create the FEValues object. +
