+New: The tensor product kernels used by FEEvaluation have gained a faster
+variant for evaluating gradients derived from spectral identities. This
+improves performance of the Laplace operator evaluation by 10-20% in the
+computation-bound case.

+New: The FEEvaluation::read_dof_values and
+FEEvaluation::distribute_local_to_global now use dedicate gather (AVX2,
+AVX-512) and scatter (AVX-512) instructions for faster vector access if those
+are available.
