 This file records noteworthy changes.
 
+1.3.1 (04 May 2005)
+* integral() and eval_integ() can be used from ginsh.
+* Integrals can be series-expanded.
+* Fixed a library initialization problem.
+* GiNaC compiles from tarball even if lex/flex is missing.
+* Fixed bugs in canonicalize_clifford(), clifford_prime() and clifford_to_lst().
+* clifford_moebius_map(), remove_dirac_ONE() and LaTeX output of Clifford
+  objects now care about representation labels.
+* Fixed bug in gcd.
+* Better output for slashed expressions
+
 1.3.0 (19 October 2004)
-* Clifford algebra has been generalized (V. Kisil).
-* Symbolic integration class added (C. Dams).
-* The multiple polylogarithm Li now evaluates numerically for arbitrary arguments.
-* New function G added (another notation for a multiple polylogarithm).
+* The Clifford classes have been generalized to allow working with Clifford
+  algebras generated by arbitrary symmetric tensors or matrices. Also, a lot
+  of new functions for Clifford algebras have been added, including
+  automorphisms and Moebius transformations. [V. Kisil]
+* Added some basic symbolic and numeric integration facilities. [C. Dams]
+* The multiple polylogarithm Li() now evaluates numerically for arbitrary
+  arguments.
+* New functions G(a,y) and G(a,s,y) added (another notation for multiple
+  polylogarithms).
 
 1.2.4 (12 October 2004)
 * Added ex::unitcontprim() to compute the unit, content, and primitive parts
