 - **Removed PhantomJS**: PhantomJS was deprecated in [Grafana v6.4](https://grafana.com/docs/grafana/latest/guides/whats-new-in-v6-4/#phantomjs-deprecation) and starting from Grafana v7.0.0, all PhantomJS support has been removed. This means that Grafana no longer ships with a built-in image renderer, and we advise you to install the [Grafana Image Renderer plugin](https://grafana.com/grafana/plugins/grafana-image-renderer).
