#What happened

We upgraded our diagram rendering backend to support additional diagram types. The upgrade introduced a problem with interactive diagrams: Mermaid and PlantUML diagrams containing links.

The problem appeared when using the zoom controls on a diagram with interactive elements, and when viewing such a diagram as a thumbnail in the browser.


#How you would have known

  • Zoom controls behaving oddly on a diagram containing links

  • Interactive diagrams rendering incorrectly as thumbnails


#Customer data


#Resolution

We identified the cause and shipped a fix. No action was needed from customers.
