[Download]

Bugfixes

  • Shortest Path and Heatmap tools not working for Undirected Graphs (bug 559866 )
  • Colors not imported in DOT (bug 559846)
  • Can't import a CSV (bug 557305)

  • Settle command not working for Yifan Hu layouts (bug 562822)

Usability

  • Heatmap tool description snippet corrected

API

  • In PreviewAPI, the background color has been put in the PreviewModel. The PreviewController has been updated as well.
  • Change FilterController.filter() to FilterController.filterVisible() and FilterController.select() to FilterController.selectVisible(). The controller is managing this process in a separate thread, with progress, and takes care of properties change. A more simple direct way to filter is required for headless access. The FilterController.filter() has been created and return the GraphView builded by the filter process.
  • Expose basic visualization features in a newly created Visualization API. No proper visualization API exists but its creation is necessary to avoid implementation module dependencies.
