Dear freshmeat.net subscriber,

witharr just announced version 1.5.8 of GiNaC on freshmeat.net.

The changes are as follows:

The default behavior of conjugate() for user-defined functions was changed to
avoid wrong evaluations. A user-defined conjugate_func must now be explicitly
registered. The parser now handles abbreviations as advertised in the manual.
Two bugs were fixed in the GCD code (one infinite loop, one miscalculation).
Dangerous iterator use was fixed. A memory leak in excompiler was fixed. 
Several
syntax issues with respect to gcc 4.5 and with respect to compile option
-std=cxx0x were fixed. A wrong URL and a texinfo problem in the manual were
fixed. The degree_vector() utility function was added.

Project description:

GiNaC (GiNaC is Not a CAS (Computer Algebra System)) is a C++ library for
symbolic calculations. It is designed to allow the creation of integrated
systems that embed symbolic manipulations together with more established areas
of computer science (like computation-intense numeric applications, graphical
interfaces, etc.). Contrary to other CASes it does not try to provide 
extensive
algebraic capabilities and a simple programming language but instead accepts a
given language (C++) and extends it by a set of algebraic capabilities.
