 1.0.13 (<date>)
 * 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.
 
 1.0.12 (30 October 2002)
 * Fixed a bug in power::expand() that could produce invalid expressions.
