This note outlines some of the changes in the new XLISP-STAT release from Release 2. There are a large number of minor changes, mostly in the basic XLISP system. These changes move the basic XLISP closer to Common Lisp , and include the addition of packages, multiple values, other improvements from XLISP-PLUS 2.1g , and a byte code compiler. Wherever possible, changes have been made in such a way as to maintain backward compatibility. In a few, hopefully minor, cases this was not possible; these cases should be noted below.
If you notice anything that has changed and is not mentioned here, please let me know. If any change causes exceptional grief, please let me know as well.
