This message announces the availability of JACAL release jacal1a8.

New in jacal1a8 are:

	* builtin.scm (equatecoeffs): added.
	* builtin.scm (equate-coeffs): Remove duplicates.
	* hensel.scm (remove-duplicates): Moved to SLIB.
	* combin.scm (del): Moved from "ff.scm".
	* ext.scm, elim.scm, poly.scm, norm.scm: promote -> poly:promote
	* builtin.scm (coeff coeffs): added to properly process
	polynomials with rational coefficients.
	* hensel.scm (mri): Added global state `ideal:prngs' to reduce
	chance of reentrant random calls.

	* rw.math: updated.  The previous version had some errors.

JACAL is a symbolic mathematics system for the simplification and
manipulation of equations and single and multiple valued algebraic
expressions constructed of numbers, variables, radicals, and algebraic
functions, differential, and holonomic functions.  In addition,
vectors and matrices of the above objects are included.

JACAL is written in Scheme.  A version of Scheme (IEEE P1178 and R4RS
compliant) written in C is available with JACAL.  SCM runs on Amiga,
Atari-ST, MacOS, MS-DOS, OS/2, NOS/VE, Unicos, VMS, Unix and similar
systems.

Documentation is included in the distribution.  Documentation is also
online at:
