 This file records noteworthy changes.
 
-1.5.0 (<date>)
+1.5.6 (28 January 2010)
+* Fixed compile problem with gcc 3.4.
+* Improved excompiler: The ginac-excompiler script will only be installed if
+  excompiler is supported and enabled.
+
+1.5.5 (04 November 2009)
+* Correct libtool versioning.
+
+1.5.4 (02 November 2009)
+* Default parser now can again read in user defined classes.
+* Add mul::info() and add::info() support for numeric info_flags (GiNaC now can
+  detect that the sum or product of a number of positive expressions is again a
+  positive expression).
+* Fixed cast that caused compile error on 64bit machines.
+* Fixed incorrect uses of STL iterators.
+* Removed subdirectory debian.
+* Output LaTeX-symbols using \mathrm, instead of \mbox.
+
+1.5.3 (30 July 2009)
+* The parser now understands user-defined functions by default. The identifier
+  names can now contain underscores.
+
+1.5.2 (10 July 2009)
+* Fixed documentation of return_type_info()
+* Fixed cstdio include issue.
+* GiNaC now requires at least version 1.2.2 of cln.
+
+1.5.1 (25 February 2009)
+* Fixed compiling problems with GNU g++ 3.4.
+* Work around weird C++ RTTI behaviour on woe32 so GiNaC works on MinGW again.
+
+1.5.0 (17 February 2009)
 * Added polynomial factorization.
-* Added an additional (recursive descent) expression parser.
-* gcd now allows the user to override (some of the) heuristics.
+* 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 (<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
