-1.4.0 (<date>)
+1.5.0 (17 February 2009)
+* Added polynomial factorization.
+* New, faster (recursive descent) expression parser.
+* Faster GCD computation.
+* gcd() now allows the user to override (some of the) heuristics.
+* Writing extensions classes is simpler now:
+  - Replaced custom RTTI by standard C++ RTTI.
+  - Definition of archiving methods now optional when declaring a new GiNaC class.
+* Fixed recursion in polynomial divide that caused a significant slowdown in
+  sqrfree().
+* Improved lsolve() of systems containing non-numeric coefficients.
+* Removed implicit conversions from cl_N to numeric.
+* Improved configuration and compatibility.
+
+1.4.4 (7 Nov 2008)
+* Fixed a bug in the multiple polylogarithms Li/G that caused imaginary parts
+  of the arguments to be ignored. 
+* Fixed archiving of complex numbers.
+* Made the behaviour of class function more consistent with respect to
+  ncmul::eval().
+* Fixed bug in power::is_polynomial.
+* Improved heur_gcd() so it can handle rational polynomials.
+* Improved build scripts.
+
+1.4.3 (04 April 2008)
+* Fixed bug in numerical evaluation of multiple polylogarithms and
+  alternating multiple zeta values introduced in version 1.4.2.
+* Nielsen polylog now invalidates its lookup tables in case the precision
+  (Digits) has been changed.
+* Added new checks for recent bugs in the numerical evaluation of Li and zeta.
+
+1.4.2 (03 April 2008)
+* Fixed VPATH building of documentation.
+* Fixed bug in numerical evaluation of multiple polylogarithms for arguments
+  equal to certain roots of unity (thanks to Jianqiang Zhao).
+* Fixed check for memory leakage in parser.
+* Made internal function coerce() standard compliant.
+* Improved lsolve() of systems containing non-numeric coefficients.
+* Improved automatic test programs. Now they work on MinGW and Cygwin as well.
+
+1.4.1 (21 November 2007)
+* Fixed memory leak in ginac_yylex().
+* Fixed memory leaks in mul::eval() and power::eval().
+* Fixed macro checking for version of libreadline (Mac OS X).
+* Fixed broken preprocessor instruction in excompiler.cpp.
+* Fixed broken module loading in excompiler.cpp.
+* info(info_flags::has_indices) now works for sums and products.
+* Improved mul::expand().
+* Improved CLN output.
+
+1.4.0 (31 August 2007)
 * New tinfo mechanism.
 * Removed rtt from class symbol.
 * Faster archiving by adding a map from strings to indices in the atoms vector.
