+Revision history for Perl module Tree::DAG_Node.
+
+2007-12-02 David Hand cogent@cpan.org
+
+ * release 1.06 -- new maintainer. No code changes.
+
+2004-12-29 Sean M. Burke sburke@cpan.org
+
+ * release 1.05 -- just repackaging. No code changes.
+
+2001-02-23 Sean M. Burke sburke@cpan.org
+
+ * Release 1.04 -- bugfix: Olegt@dreamtime.net notes a bug in
+ depth_under that apparently always makes it return 0. Fixed.
+
+2000-05-13 Sean M. Burke sburke@cpan.org
+
+ * 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).

+2000-03-05 Sean M. Burke sburke@netadventure.net
+
+ * 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.
+
+1998-10-28 Sean M. Burke sburke@netadventure.net
+
+ * 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.
