 * Contracting epsilon tensors with Euclidean indices now works.
 * Improved dummy index symmetrization in sums.
+* Added dirac_gammaL/R(), which can be used instead of dirac_gamma6/7()
+  but are single objects, to allow for a more compact notation of Dirac
+  strings.
+* Powers with negative numeric exponents are printed as fractions in the
+  LaTeX output.
