Version 0.2.1
------------------------------------------------------------------------------

* Update to fix outstanding R CMD check issues.

Version 0.2 (2010-11-11)
------------------------------------------------------------------------------

NEW FEATURES

  * Memoised functions now have an attribute memoised=TRUE, and
    is.memoised() tests whether a function is memoised. (Contributed by
    Sietse Brouwer.)

IMPROVEMENTS

  * Documentation is now more elaborate, and hopefully more accessible to
    newcomers. Thanks to Sietse Brouwer for the verbosity.
