We are very pleased to announce the release of Graphcanvas 4.1.0. This minor release includes several improvements including:

• A mostly complete test suite
• Improved node and edge rendering (and nicer arrows for directed graphs)
• Python 3 compatibility
• A new GraphNodeDragTool

We are very thankful for the contributions and PR reviews from Mark Dickinson, Ioannis Tziakos, Joris Vankerschaver, and Corran Webster.
