1.2.0

• Improved flowchart and state-diagram connections with simpler curves, better spacing between edges, and clearer arrowheads and labels.
• Flowcharts preserve the order of nodes as written when rearranging them would not reduce crossings.
• Stepped flowchart connections use separate tracks and rounded corners.
• Added --pele-critical for critical Gantt tasks and high Kanban priorities. Low Kanban priorities use the muted color. Gantt task labels have more space beside their bars.
• XY chart lines render over bars regardless of declaration order. When showDataLabel is enabled, bar values appear outside the bars; showDataLabelOutsideBar no longer changes their position.
• Added the linkRel render option to set the rel attribute on every diagram link, including internal links. It defaults to noopener. Use noopener nofollow to add nofollow, or an empty string to omit the attribute.
• Expanded the website’s examples with a page for each diagram type, including Mermaid’s documentation examples and additional layout examples. Example cards adapt to their container width.
