This file records noteworthy changes.
-1.0.5 (<date>)
+1.0.10 (<date>)
+* Powers of indexed objects are now parenthesized correctly in LaTeX output.
+* Input parser handles indices (they have to be specified in the same list
+ as the symbols).
+
+1.0.9 (11 June 2002)
+* simplify_indexed() now raises/lowers dummy indices to canonicalize the index
+ variance. This allows some simplifications that weren't possible before,
+ like eps~a.b~c~d*X.a*X~b -> 0 and X.a~a-X~a.a -> 0.
+* Implemented relational::subs().
+* Fixed bug in simplify_ncmul() for clifford objects.
+
+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 2001)
+1.0.4 (24 January 2002)
* Speedup in expand().
* Faster Bernoulli numbers (Markus Nullmeier).
* Some minor bugfixes and documentation updates.
