Announce: FriCAS 1.2.0 has been released

[Waldek Hebisch]

This is copy of annoucement that I posted in the newsgroups:

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 1.2.0 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 1.1.8):

- New MatrixManipulation package.

- New ParallelIntegrationTools package.

- Gruntz algorithm in now used also for finite one-sided limits.

- FriCAS has now true 2-dimensional arrays (previously they were
emulated using vectors of vectors).

- Speedups in some matrix operations and in arithmetic with
algebraic expressions.

- FreeModule is now more general, it allows Comparable as second
argument.

- Changed Spad parser, it now uses common scanner with interpreter.
Spad language is now closer to interpreter language and Aldor.
'leave' is removed, 'free', 'generate' and 'goto' are now keywords.
Pile rules changed slightly, they should be more intuitve now.
Error messages from Spad parser should be slightly better.

Bug fixes, in particular:

- Fixed a few build problems.

- Eliminated division by 0 during 'normalize'.

- 'nthRootIfCan' removes leading zeros from generalized series
(this avoids problems with power series expanders).

- Fixed corruption of formal derivatives.

- Fixed two problems with fortan output.

- Fixed ')untrace' and ')undo'. Fixed ')trace' with ECL.

- Fixed problem with calling efricas if user default shell is (t)csh.

Sorry.

For most lisps, init files are not loaded when building fricas (and this
is good). Let's be consistent:

Actally, I find it sad that due to various problems we have to
skip init files.

OK, applied.
