This file records noteworthy changes.
-0.9.4 (<date>)
-* interface cleanups and bugfixes.
+1.1.0 (<date>)
+* Removed deprecated macros is_ex_a, is_ex_exactly_a and friends for good.
+* Made the hashing more simple and efficient.
+* The scalar_products mechanism allows the specification of an index dimension.
+
+Backlog from 1.0.n:
+* 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).
+* Added some limited support for subspaces in the idx and tensor classes.
+* Fixed a bug in canonicalize() (antisymmetric canonicalization of an already
+ sorted list containing two or more equal objects failed to return 0).
+* 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.
+* Fixed LaTeX output of indexed and matrix objects and powers thereof.
+* Fixed matrix::pow(n) for n==0.
+* "(x+1).subs(x==x-1)" now returns the correct result "x" instead of "x-1".
+* (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).
+* Speedup in expand().
+* Faster Bernoulli numbers (Markus Nullmeier).
+* Fixed a bug where quo() would call vector::reserve() with a negative
+ argument.
+* Several small bugfices in code generation, output and documentation.
+
+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)
+ works now.
+* Fixed small bug in dummy index renaming which could cause it to not
+ recognize renamable indices in some cases.
+* power::degree() and power::ldegree() throw an exception when encountering
+ a non-integer exponent.
+* Add output-support for Python bindings.
+
+1.0.1 (22 November 2001)
+* Function sqrfree() handles a few more cases now.
+* Class relational has real canonical ordering now.
+* Handle obscene libreadline version numbers when building ginsh.
+
+1.0.0 (6 November 2001)
+* Some internal reorganization resulting in a general speed-up.
+* The last 3 evaluated expressions in ginsh are now referred to with the
+ tokens '%', '%%' and '%%%'. The old '"', '""' and '"""' remain for
+ compatibility but may be removed in a future version of GiNaC.
+
+0.9.4 (20 September 2001)
+* Functions have better support for external scripting languages.
+* Interface cleanups and bugfixes.
+* Fix silly bug in evalf() that prevented things like 2^Pi being computed.
0.9.3 (16 August 2001)
* series expansion now much more consistent for small order expansion.
