| "# Changelog\n", | ||
| "\n", | ||
| "## New features\n", | ||
| "* Support a configurable node-to-cell mapping that is considered by the automatic layout algorithms such that nodes are placed in the given grid cell. Typical use cases may be to highlight a critical path structurally by aligning these nodes in a row/column.\n", | ||
| "* Added `circular_straight_line` as new layout option that creates a circular layout with straight connections, instead of the bundled connections of the existing `circular` layout.\n", | ||
| "\n", | ||
| "## Improvements\n", | ||
| "* Adjusted the interactive organic layout settings to make the result more airy.\n", | ||
| "* Saved the executed Google Colab state in the example notebooks such that the widget can be tried without executing the notebook in Google Colab.\n", | ||
| "\n", | ||
| "## Bugfixes\n", | ||
| "* Fixed widget resizing issue after switching from map-view to the normal graph view." | ||

| "\n", | ||
