* Added polynomial factorization.
* Added an additional (recursive descent) expression parser.
* gcd now allows the user to override (some of the) heuristics.
+* Replaced custum 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 (<DATE>)
+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
