This message announces the availability of JACAL release jacal-2a1.

JACAL is an interactive symbolic mathematics program. JACAL can
manipulate and simplify equations, scalars, vectors, matrices, and
tensors of (single and multiple valued) algebraic expressions
containing numbers, variables, radicals, and transcendental functions.

JACAL is written in Scheme and works with Scheme implementations which support the SLIB Scheme Library. The (download and) installation instructions at <https://www.gnu.org/software/jacal/html/jacal-2a1/Installation.html>
include the SCM Scheme implementation optimized for use with JACAL.

JACAL is free software and part of the GNU project. It is released
under the GNU General Public License (GPL).

Documentation and distributions in several formats are linked from
JACAL's home page:

<https://www.gnu.org/software/jacal/>

jacal-2a1 news:

* The transcendental functions exp, %expt, log, tan, atan, cot,
sec, cos, sin, csc, acot, asec, acos, asin, acsc, and %W (the
Lambert-W function) are now supported!

* (::~): Added inverse-function operator.

* (::): Now defines differential recurrences (ODE).

* types.scm (math:equal?): safe replacement for equal? yields
significant performance improvement.

* repair of many bugs. Variable names and some code reorganized.

* Jacal's home page has changed to <https://www.gnu.org/software/jacal>

Thank you Jacal. You don't mind if I just print out your theory papers,
for which I've also included comp.theory, and implement my own mathema-
tics software?

Details at <http://cvs.savannah.gnu.org/viewvc/*checkout*/jacal/jacal/ChangeLog>

Best wishes, and happy symbolic mathematics!
