 This file records noteworthy changes.
 
+1.4.0 (<date>)
+
+1.3.6 (<date>)
+* Better worst case behavior in heuristic gcd [Alexei Sheplyakov].
+* ...<please continue here>...
+
+1.3.5 (17 August 2006)
+* Re-built bison related files that caused bugs with gcc 4.
+* Fixed bugs in fderivative::match_same_type(), expairseq::match(),
+  expand_dummy_sum(), and expairseq::map().
+* Fixed template specialization for class container to be gcc 4.2 compliant.
+* Output in csrc mode is now -x instead of -1.0*x.
+* Fixed tutorial and reference generation in html/pdf/ps format.
+* Modified autotool configuration to allow for compilation on MinGW.
+* Debian packaging files updated.
+
+1.3.4 (12 April 2006)
+* More general index dimensions are now possible.
+* Improved algebraic substitutions.
+* Fixed wrong matching in .has(). 
+* Fixed bug in differentiation of a power.
+* collect_common_factors also works with negative powers of common factors now.
+* Code clean-up and preparations for upcoming cln 1.2.
+
+1.3.3 (24 October 2005)
+* Fixed bug occuring in algebraic substitutions with expressions involving
+  indices.
+* Fixed bug that selected the wrong algorithm for determinants of purely
+  numeric matrices with at least one floating point element.
+* Fixed bug in function H that caused an infinite recursion for arguments
+  around +-I.
+* Fixed const-correctness in printing handler for GCC 4.0.2.
+* Made lookup in adaptivesimpson precision-aware.
+* Added series expansion for functions (classical) Li and S around x==0.
+* Added fsolve() numerical univariate real-valued function solver.
+* Added functions sub_matrix() and reduced_matrix().
+* Small cleanups. Less warnings with latest GCC.
+
+1.3.2 (10 July 2005)
+* GCD avoids to produce expanded expressions.
+* Fixed bug in expanding expressions containing dummy indices.
+* Fixed static initialization order bug.
+* collect_common_factors now works with powers.
+* Modernized configuration scripts.
+
+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
