Subject: Announce: FriCAS 1.2.1 has been released

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

Notable changes (compared to version 1.2.0):

-- Improvements to 'integrate': a new routine for integration
in terms of Ei, better handling of algebraic integrals.

-- Implemented 'erfi'.

-- Derivatives of 'asec', 'asech', 'acsc' and 'acsch' use different
formula so that numeric evaluation of derivative will take
correct branch on real axis.

-- Linear dependence package is changed to be consistent with
linear solvers.

-- It is now possible to extract empty submatrices.

-- Changed default style of 3D graphics.

-- Support for building Mac OS application bundle.

Bug fixes, in particular:

-- fixed few cases of wrong or unevaluated integrals.

-- better zero test during limit computation avoids division
by zero.

-- fixed buffer overflow problems in view3D.

-- 'reducedSystem' on empty input returns basis of correct size.
