-### Easily Switch Visualization with Panel Edit UX Update
-
-The UX for editing a panel has gotten an update and the major feature is being able to easily switch visualization using the new Visualization option. This means you can quickly switch from a Graph visualization to a Table visualization or any other visualization without having to create a new panel.
+Grafana v6.0 has a completely redesigned UX around editing panels. You can now resize the visualization area if you want
+more space for queries & options and vice versa. You can now also change visualization (panel type) from within the new
+panel edit mode. No need to add a new panel to try out different visualizations! Checkout the
+video below to see the new Panel Editor in action.

+### Gauge Panel
+
+We have created a new seperate Gauge panel as we felt having this visualization be a hidden option in the Singlestat panel
+was not ideal. When it supports 100% of the Singlestat Gauge features we plan to add a migration so all
+singlestats that use it become Gauge panels instead. This new panel contains a new **Threshold** editor that we will
+continue to refine and start using in other panels.

+### React Panels & Query Editors
+
+A major part of all the work that has gone into Grafana v6.0 has been on the migration to React. This investment
+is part of the future proofing of Grafana and it's code base and ecosystem. Starting in v6.0 **Panels** and **Data
+source** plugins can be written in React using our published `@grafana/ui` sdk library. More information on this
+will be shared closer to or just after release.
