-0.8.2 (<date>)
+0.8.3 (11 May 2001)
+* color and clifford classes are functional and documented.
+* New "spinidx" class for dotted/undotted indices.
+* Predefined spinor metric tensor (created by spinor_metric()).
+* Symbols can have a LaTeX name, e.g. symbol s("s", "\\sigma");
+* LaTeX output of indexed objects is much nicer.
+* Fix some build-problems (with recent libreadline).
+* Semantics of arithmetic operators now follows the C++ rules more strictly.
+
+0.8.2 (24 April 2001)
 * degree(), ldegree(), coeff(), lcoeff(), tcoeff() and collect() work with
   non-symbols as the second argument in ginsh.
 * the argument to collect() can be a list of objects in which case the
   result is either a recursively collected polynomial, or a polynomial in
   a distributed form with terms like coeff*x1^e1*...*xn^en, as specified by
   the second argument to collect().
+* Several bugfixes (including a nasty memory leak in .normal()).
+* class matrix: solve() doesn't call algorithms redundantly any more and
+  inverse() falls back to solve() which works in more general cases.
