-0.7.1 (--date--)
+0.7.3 (<date>)
+* Added a section to the tutorial about adding new algebraic classes to GiNaC
+
+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 temporary excess memory.
+* 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()
