- updated to 1.11
       - 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.
       - 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.
       - 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.
       - 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). (forwarded request 177506 from coolo)
