This file records noteworthy changes.
-0.9.1 (<date>)
+0.9.5 (<date>)
+* 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.
+* lsolve() accepts algorithmic hint as parameter.
+
+0.9.2 (31 July 2001)
+* Epsilon tensor is more functional.
+* simplify_indexed() is better at detecting expressions that vanish for
+ symmetry reasons.
+* Several little bugfixes and consistency enhancements.
+
+0.9.1 (27 June 2001)
+* Ctors of class numeric are not explicit any more. All built-in callers for
+ pseudofunctions are now templated and default to ex arguments which relaxes
+ the need for explicit ctors.
* New functions/methods:
- - remove_first() and remove_last() for lists
+ - find()
+ - remove_first(), remove_last(), sort() and unique() for lists
- symmetrize_cyclic()
- decomp_rational()
* Instead of just totally symmetric or antisymmetric, complex symmetries
take the trace on both sides, using diff() on a matrix differentiates every
element etc.
* diff() works properly with non-commutative products and indexed objects.
+* New option flag "expand_function_args" for expand().
* Supplement some (now deprecated) macros by inlined template functions:
- is_of_type(foo, type) -> is_a<type>(foo)
- is_ex_of_type(foo, type) -> is_a<type>(foo)
- is_exaclty_of_type(foo, type) -> is_exaclty_a<type>(foo)
- is_ex_exaclty_of_type(foo, type) -> is_exaclty_a<type>(foo)
- ex_to_foobar(baz) -> ex_to<foobar>(baz)
-* rem(c, p[x], x) erroneously returned p[x] instead of c.
+* rem(c, p[x], x) (c: numeric, p[x]: polynomial) erroneously returned p[x]
+ instead of c.
+* Small bugfixes in pattern matching.
+* Updated libtool to version 1.4.
0.9.0 (7 June 2001)
* In the output and in ginsh, lists are now delimited by { } braces, and
