 This file records noteworthy changes.
 
+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.
+
+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.
