• Release 1.04 -- bugfix: Olegt@dreamtime.net notes a bug in depth_under that apparently always makes it return 0. Fixed.

• Release 1.03 -- superficial changes:
• Minor doc spiffing-up.
• Noting my new email address.
• In order to keep its symbol table clean, DAG_Node no longer imports routines from Carp and UNIVERSAL. Should have no effect on existing code.
• I went and commented out all the places where I have asserts for non-cyclicity. I once had the idea that DAG_Node could be a base class for graphs that /could/ allow cyclicity, or something like that, so those assertions would apply for methods that work only for acyclic networks. But, in time, I realized that almost everything in DAG_Node would have to have such assertions. Moral of the story: DAG_Node has nearly no code that it could share with a class for anything but DAGs. And since DAG_Node does everything it can to /keep/ you from making cyclicities, there's no point in constantly having assertions of noncyclicity (especially when these assertions are rather expensive to check).

• Release 1.02 -- minor bugfixes:
• Fixed a typo in the docs: corrected one "right_sisters" to "right_sister"
• Initialized a variable to '' to avoid warnings under -w. Thanks to Gilles Lamiral.

1999-05-14 Sean M. Burke sburke@netadventure.net

• Releass 1.01 -- major additions:

        Scads of new methods.  Still (as far as I know) backward
        compatible with all previous versions.  Some minor changes in
        coding, not affecting the interface.

        Hopefully more friendly to users that use -w (warnings).

        Cautionary tale: I started making big changes to this right around
        mid-November 1998.  But I kept thinking "oh, ONE MORE change and
        then I'll release it."  Famous last words!  Other things came up,
        I forgot what was new and what was different in this module
        (which is why you don't see a detailed list of differences here),
        altho apparently somehow I managed to document all the new
        methods.

1998-11-03 Sean M. Burke sburke@netadventure.net

• Release 0.75 -- minor changes:

New methods new_daughter, new_daughter_left.

$obj->new constructor syntax now documented.

        Internal accesses to "daughter" and "mother" attribs
        are now direct, for efficiency's sake.

        Minor improvements to the docs.

• Release 0.74 -- whoops, forgot to bundle the README. No change in the module.

1998-10-27 Sean M. Burke sburke@netadventure.net

• Release 0.73 -- first release version.
