 This file records noteworthy changes.
 
+1.0.8 (31 March 2002)
+* Improvements in memory usage of the expand() methods.
+
+1.0.7 (18 March 2002)
+* Fixed LaTeX output of indexed and matrix objects.
+* Fixed matrix::pow(n) for n==0 and added helper functions to create unit
+  matrices "ex unit_matrix(unsigned, unsigned)".
+
+1.0.6 (4 March 2002)
+* "(x+1).subs(x==x-1)" now returns the correct result "x" instead of "x-1".
+
+1.0.5 (27 January 2002)
+* (l)degree(s), coeff(s, n) and collect(s) were extended to accept expressions
+  of any class (except add/mul/ncmul/numeric) for "s". They should even work
+  if "s" is a "power" object, as long as the exponent is non-integer, but with
+  some limitations. For example, you can "collect(a*2^x+b*2^x, 2^x)" to get
+  "(a+b)*2^x", but "degree(2^(3*x), 2^x)" yields 0 instead of 3).
+* Fixed a small output bug.
+
+1.0.4 (24 January 2002)
+* Speedup in expand().
+* Faster Bernoulli numbers (Markus Nullmeier).
+* Some minor bugfixes and documentation updates.
+
+1.0.3 (21 December 2001)
+* Fixed a bug where quo() would call vector::reserve() with a negative
+  argument.
+* Fix several bugs in code generation.
+
 1.0.2 (19 December 2001)
 * Input parser recognizes "sqrt()", which is also used in the output.
 * divide(a,b,q) only modifies q if the division succeeds; also, divide(a,b,a)
