-0.6.5 ()
+0.7.3 (28 February 2001)
+* Several bugfixes and minor performance tunings.
+* Added a section to the tutorial about adding new algebraic classes to GiNaC.
+* Closed many in-source documentation gaps.
+
+0.7.2 (17 February 2001)
+* Several bugfixes in power series expansion, one of them critical.
+
+0.7.1 (7 February 2001)
+* Fix problems with Cint that were caused by CLN's overloaded operator new.
+* Fix compilation errors with GCC3.
+* normal() handles large sums of fractions better and normalizes the exponent
+ of power expressions.
+* expand() always expands the exponent and transforms x^(a+b) -> x^a*x^b.
+* Some bugfixes of series expansion around branch cuts of special functions.
+
+0.7.0 (15 December 2000)
+* Requires CLN 1.1 now. Class numeric doesn't use an indirect pointer to the
+ actual representation any more. This is a speedup.
+* mul::expand() was reengineered to not allocate excess temporary memory.
* Non-integer powers of a symbol are treated as constants by (l)degree() and
- coeff(). Using these functions on an expression containing such powers used
- to fail with an internal error message. The side-effect is that collect()
+ coeff(). Using these functions on an expression containing such powers used
+ to fail with an internal error message. The side-effect is that collect()
can be used on expressions which are not polynomials.
+* Added a man page for the ginac-config script.
+* Ctor of numeric from char* honors Digits.
0.6.4 (10 August 2000)
* Complete revamp of methods in class matrix. Some redundant (and poor)
