-* Fixed a bug in power::expand() that could produce invalid exressions.
+1.0.13 (<date>)
+* Contracting epsilon tensors with Euclidean indices now works.
+* Improved dummy index symmetrization in sums.

+ strings.
+* Powers with negative numeric exponents are printed as fractions in the
+ LaTeX output.
+* Added symbolic_matrix() for the convenient creation of matrices filled
+ with symbols.
+* Added collect_common_factors() which collects common factors from the
+ terms of sums.
+* simplify_indexed() converts "gamma~mu*p.mu" to "p\".
