-1.0.10 (<date>)
+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.
+* 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.
+* The input parser no longer ignores extra data following accepted input.
+* Improved the CLN C-source output (integers are printed as integers, and
+  floating point numbers include the precision).
+* Fixed a problem in the LaTeX-output of negative fractions.
+* Added print_latex() and print_csrc() to ginsh.
+* The sprem() function is now public.
+
+1.0.11 (18 September 2002)
+* Fixed a possible memory corruption in contractions of indexed objects with
+  delta or metric tensors.
+* Computing the derivative of a power series object with respect to a symbol
+  that is not the expansion variable now works correctly.
+* Several bugfixes in code generation.
+
+1.0.10 (24 July 2002)
 * Powers of indexed objects are now parenthesized correctly in LaTeX output.
 * Input parser handles indices (they have to be specified in the same list
   as the symbols).
