-1.0.13 (<date>)
+1.0.14 (<date>)
+* Improved the C-source output: complex numbers are printed correctly (using
+ the STL complex<> template or cln::complex()), rational numbers use cl_RA()
+ in the CLN output, and small integers are printed in a more compact format
+ (e.g. "2.0" instead of "2.0000000e+00").
+* function_options::set_return_type() and function_options::do_not_evalf_params()
+ now actually work.
+
+1.0.13 (27 January 2003)
* 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.
+* 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\".
1.0.12 (30 October 2002)
* Fixed a bug in power::expand() that could produce invalid expressions.
