The first version was a Lisp with [[object-oriented programming|object-oriented]] extensions for computers with limited power. The second version (XLISP 2.0) moved toward [[Common Lisp]], but was by no means a complete implementation. After a long period of inactivity, the author released a new version based on [[XSCHEME]], his Scheme implementation. The most current version follows the [[Scheme (programming language)|Scheme]] R3RS standard.{{fact|date=January 2016}}
