    Dear All,

    We are happy to announce a new edition of
    the Dogelog Player:

    - Enhanced core (IEEE Comparisons):
    The special value 0rNaN received comparison
    drawn from IEEE. The built-in (=\=)/2 now
    implements not quiet, while the built-ins
    (=:=)/2, (<)/2, etc. now implement quiet.
    The built-ins (@<)/2, etc. now implement
    quiet ordered, while the built-ins min/3
    and max/3 now implement number.

    - Goal Inlining/Outlining:
    We noticed performance problems of negation
    as failure (\+)/2 when the argument is a
    complex goal. Many Prolog systems don't
    suffer from this problem. We implemented
    a form of goal expansion, but with reversibility,
    so that rewritten (\+)/2 calls are seen
    again in listing/[0,1] and trace/0.

    - Just-in-Time Indexing:
    The scope is currently MAX_INDEX = 2
    indiscriminantly for static and dynamic
    predicates. The system can dynamically
    allocate 1st or 2nd argument indexes when
    needed, and even create combined 1st+2nd
    argument indexes. The enhancement comes
    with a new jiti_list/[0,1] utilitiy.

    Have Fun!
