Lisp is a family of languages, there hasn't been a single Lisp language since the 1960s. The different dialects of Lisp add new features.

  However, the major ANSI dialect hasn't changed since 1994, so OP has a fair point.

    Common Lisp is a standard, but the various implementations of that standard have added non-standard features. For example, I believe Unicode support was added to SBCL around 2004.
