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:

jacal-2a1 news:

 * init.math (exp, %expt, log, %e, tan, atan, %pi, cot, sec, cos, sin,
   csc, acot, asec, acos, asin, acsc, %W): defined as differential
   equations and inverse functions; %W is the Lambert-W function.

   This support for transcendental functions is a major increase in
   Jacal's abilities!

 * (::~): 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>
