An alpha-level new release of XLISP-STAT, Release 3.47, is now
available for anonymous ftp from umnstat.stat.umn.edu (128.101.51.1)
in

	pub/xlispstat/Alpha

UNIX sources, Macintosh and MS Windows executables are provided.

This is not intended as a general release. I am making this
preliminary release to get some help working out any kinks introduced
by a large number of internal changes I made. Most of the changes
should be under the hood and have no visible effect on user code. (At
lest that is the theory). If you do try this version, please let me
know how it works out, in particular if you run into problems.

This release does add some functionality at the Lisp level, such
handling of 'apply' place forms in setf, BOA constructors in
defstruct, and a simple version of symbol-macrolet. It also includes
changes in the linear algebra routines that should speed up regression
and glim computations for larger models (10 variables, 100 cases and
up at least). The internal changes to the linear algebra system are
not yet documented since they are not completely finalized, but if you
are interested you can look at linalg.lsp to get an adea of where
things are headed.

There is one important change, however:

	    **** ALL .FSL FILES NEED TO BE RECOMPILED ****

for use with this release. Old files may in fact still work if they do
not use any of the features that changed, but if they don't work, the
nature of failure is not predictable. Old .fsl files did not contain
version information to use for signaling a possible incompatibility,
but ones prodced by this and future releases will contain such
information.

Changes:

3.44 - 3.45:

	Fixed bug in window size and location messages in MS Windows
	version (only seemed to affect Win16 version).


3.45 - 3.46:

	Added debug option to MSDOS makefile.

	Added blas tests and tests for matmult and sweep stuff to test files.

	Reimplemented matmult, sweep code, and other matrix code to use
	C arrays and BLAS/LINPACK/EISPACK. Added direct interface to some
	LINPACK, EISPACK, BLAS Level 2 and BLAS Level 3 routines.

	Added some utility functions to support using C arrays.

	Added THE macro.

	Changed regression-model-proto compute, :fit-values, and :x
	methods to use internal C arrays and to use diagonals from
	sweep matrix in tolerance assessment.

	Added +Onolimit to UCFLAGS for HP so xlbcode.c gets optimized.

	Fixed macro version of in-package to avoid core dump if
	package does not exist.


3.46 - 3.47:

	Added test for System V matherr function to configure.in; added
	matherr function to stuff files for handling errors signaled
	with matherr.

	Fixed bug in simplifier for VALUES and VALUES-LIST to find
	bound continuation.

	Made complex math stuff local to xlmath2.c. Cleaned up complex
	math code; changed to use f2c and SLAPACK routines.

	Made handling of infinities, NaN's in format standard.

	Reimpelemted defstruct as macro. New version allows BOA
	constuctors. Also defines compiler macro for accessors -- may
	not be optimal.

	Added version check for FSL files.

	Added limit on number of backtrack steps in newtonmax to avoid
	NaN problems

	Dropped STRCAT entry from xlisp.hlp; updated SUBSEQ entry.

	Fixed destructuring-bind to work on list arguments other than
	only the first

	added several internal setf methods; new opcodes for car and
	cdr setf methods

	Added environment functions variable-information,
	function-information, etc..  Added macro-function.

	Modified macroexpand and macroexpand-1 to look for FSUBR
	macros in the MACRO property of a symbol.

	Fixed up order of &whole and &environment processing.

	Changed macro expander functions to be as specified in CLtL2.

	Changed setf to macro.

	Added macro version of locally and function special-form-p.

	Added define-compiler-macro.

	Split Common Lisp code into three files, common.lsp,
	common2.lsp and common3.lsp.

	Added some more setf methods for things handled by the
	internal version.

	Changed compile-file's macrolet handler to use parse-macro.

	Fixed macrolet handler in compiler to use parse-macro.

	Added macro definitions for some non-standard special forms.

	Added symbol-macrolet as autoload.

	Added *simplify-setf* variable for controlling setf expansion.

	Added function definition for complement replacing internal
	FSUBR.

	Patched SunOS 4.1.3 printing problem. Internal version of
	memmove is now used if none is found in standard libraries by
	configure.

	Added opcode for %INITIALIZE-0 to handle initialization for
	functions with only required args.

	Added apply setf method.

	Changed to have oscheck checked on every do_goto in byte code.
