Revision history for Perl module Tree::DAG_Node. 1.12 Wed Jul 3 16:38:00 2013 - Change text in README referring to licence to match text in body of source, since it was in conflict with the Artistic Licence V 2.0. This was requested by Petr Pisar who packages stuff for Red Hat. - Rename CHANGES to Changes as per CPAN::Changes::SPEC. - Various spelling fixes in the docs, as kindly reported by dsteinbrunner. 1.11 Mon Feb 4 09:50:00 2013 - Correct the date (2012 -> 2013) in this file used for V 1.10. - Correct the text at L<Tree::DAG_Node/AUTHOR> so it refers to Artistic License 2.0, which now matches what it says in Build.PL and Makefile.PL. Resolves RT#83088. 1.10 Fri Feb 1 08:53:00 2013 - Change t/pod.t to look for Test::Pod 1.45, but comment out Test::Pod in Build.PL and Makefile.PL. This means Test::Pod is not used at all if it is not installed. As per RT#83077. 1.09 Thu Nov 8 12:38:00 2012 - No code changes. - Oops. The changes in V 1.08 we made in the other 10 distros, but not in this one. My apologies. 1.08 Thu Nov 8 12:38:00 2012 - No code changes. - For pre-reqs such as strict, warnings, etc, which ship with Perl, set the version # to 0. Reported as RT#80663 by Father Chrysostomos for Tree::DAG_Node. 1.07 Thu Nov 1 12:47:00 2012 - New maintainer: Ron Savage - Pre-emptive apologies for any changes which are not back-compat. No such problems are expected, but the introduction of new methods may disconcert some viewers. - Fix RT#78858, reported by Gene Boggs. Audit code for similar problems. - Fix RT#79506. reported by Ron Savage. - Rename ChangeLog to CHANGES, and add Changelog.ini. - Replace all uses of cyclicity_fault() and Carp::croak with die. - Remove unused methods: decommission_root(), cyclicity_allowed(), cyclicity_fault(), inaugurate_root(), no_cyclicity() and _update_links(). OK - cyclicity_fault() was called once. It just died. - Add methods: format_node(), hashref2string(), is_root(), node2string(), tree2string(). tree2string($opts, $node) - unlike draw_ascii_tree() - can optionally print the tree starting at any node. Override format_node(), hashref2string(), and node2string() if desired. - Reformat the POD big-time. - Add Build.PL. - Re-write Makefile.PL. - Remove use vars(@ISA $Debug $VERSION). Replace latter 2 with 'our ...'. - Rename t/00_about_verbose.t to t/about.perl.t. - Add scripts/cut.and.paste.subtrees.pl. Warning: Some trees get into an infinite loop. - Add t/cut.and.paste.subtrees.t. Warning: Some trees get into an infinite loop. - Document the options (discouraged by Sean) supported in the call to new($hashref). 1.06 Sun Dec 2 12:00:00 1998 - New maintainer: David Hand. - No code changes. 1.05 Wed Dec 29 12:00:00 1998 - Just repackaging. - No code changes. 1.04 Fri Feb 23 12:00:00 1998 - Bugfix: Olegt@dreamtime.net notes a bug in depth_under that apparently always makes it return 0. 1.03 Sat May 13 12:00:00 1998 - 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). 1.02 Sun Mar 05 12:00:00 1998 - 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. 1.01 Fri May 14 12:00:00 1998 - 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. 0.75 Tue Nov 3 12:00:00 1998 - 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. 0.74 Wed Oct 28 12:00:00 1998 - Whoops, forgot to bundle the README. - No change in the code. 0.73 Tue Oct 27 12:00:00 1998 - First release.
