FriCAS is an advanced computer algebra system. Its capabilities
range from calculus (integration and differentiation) to abstract
algebra. It can plot functions and has integrated help system.

FriCAS 1.1.8 builds on Linux and many Unix like systems (for example
Mac OSX and Solaris 10). FriCAS is build on top of Common Lisp; several
Lisps can compile and run FriCAS -- currently supported are GCL,
SBCL, Clisp, ECL, Closure CL.

Notable changes (compared to version 1.1.7):

- Improvements of pattern matching integrator, it can now integrate
in terms of Fresnel integrals and better handles integrals in terms
of Si and Ci.

- Better integration of symbolic derivatives.

- Better normalization of Liouvillian functions.

- New package for computing limits using Gruntz algorithm.

- Faster removal of roots from denominators.

- New domains for mutivariate Ore algebras and partial differential
operators.

- New package for noncommutative Groebner bases.

- New domain for univariate power series with arbitrary exponents.

- New special functions: Shi and Chi.

- New package for noncommutative Groebner bases.

- New domain for univariate power series with arbitrary exponents.

- New special functions: Shi and Chi.

- Several aggregates (in particular tables) allow more general
parameter types.

- New domain for hash tables using equality from underlying
domain.

Bug fixes, in particular:

- Fixed problem with gcd failing due to bad reduction.

- Fixed series of 'acot' and Puiseux series of several special functions.

- Fixed wrong factorization of differential operators.

- Fixed build problem on recent Mac OS X.
