-0.8.1 (15 April 2001)
+0.8.3 (<date>)
+* 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).
+
+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.
+
+0.8.1 (16 April 2001)
 * degree(), ldegree(), coeff(), lcoeff(), tcoeff() and collect() can now
   be used with constants, functions and indexed expressions as well, so you
   can use it to collect by powers of Pi or sin(x), or to find the coefficient
