Changes for version 2.22

  • Fix handling of graph attributes which are for clusters but not for subgraphs. See scripts/sub.graph.frames.pl for sample code. See the demo page for the output of that script. See the new FAQ item 'How do I specify attributes for clusters?' for details. Many thanx to Bill Hollingsworth (private email) for prompting me to investigate this bug.
  • Document method default_subgraph().
