 ## Accessibility
 
 We’ve continued to make progress on improving Grafana’s accessibility. In Grafana 8.3 we’ve updated the main menu with improved keyboard navigation. We’ve also improved Grafana’s behavior when navigating through elements with the tab key (tab stops) and finished our work to make Grafana’s viewer roles compatible with assistive technologies such as screen readers. You can read our accessibility statement here and reach out to us with accessibility issues using our community Slack or our community forums.

 Grafana will now make suggestions for visualization types based on the current data surfaced by a query or queries in a panel. This makes seeing available, possible interpretations of your data more straightforward and can be a useful jumping-off point when building panels and dashboards with specific goals in mind.

 ### Candlestick Panel (Beta)
 
-Grafana 8.3 is shipping with a new Candlestick panel that is so much more. Beyond candlesticks and open, high, low, high, close, behaviors, it includes customizable up/down colors, bar color determined by intra-period or inter-period movement of the data, volume histogram with matching colors, and the ability to detach or create a separate volume histogram to allow for more flexible dashboard design. You can read more about it here [link to do].

+### Geomap updates
+
+The Geomap panel has been updated to support multiple data layers. The panel can now be configured with multiple markers, heatmaps & GeoJSON layers. The layers can be individually configured, named, and re-ordered to create rich, multidimensional visualizations. Please see the documentation for details on how you can set up and configure these new configuration options.

+## Grafana Alerting
+
+Grafana Alerting is now the default alerting experience for all new Open Source installations of Grafana 8.3. Grafana Alerting in 8.3 includes the ability to test contact points and notification routing. Grafana 8.3 also adds the ability to configure and use external, Prometheus-style alert managers from within the Grafana Alerting workflow.

 Sometimes the Viewer, Editor, and Admin roles just don’t fit what a certain user needs to do in Grafana. Now you can assign fine-grained roles directly to users, so they can create reports, use Explore mode, create data sources, and perform other specific actions in Grafana. The role picker can be access from the Grafana Admin user management page.

 ## Use fine-grained access control for Organizations and Licensing (beta)
 
 We’ve added new permissions to fine-grained access control to help you specify actions that users can perform. Now you can assign permissions to manage Organizations and License functions in Grafana, in addition to Users, Data Sources, Reports, and other resources. Fine-grained access control remains in beta and we will continue to add new permissions until all of Grafana’s endpoints are covered. For a complete list of the actions you can permit using fine-grained access control, see the [reference](https://grafana.com/docs/grafana/next/enterprise/access-control/fine-grained-access-control-references/).

 Are you tired of managing user permissions because your license only allows a certain number of Viewers and Editors or Admins? So were we. We’ve added support for combined user pricing, where all users cost the same and fall into the same license bucket in Grafana Enterprise. This is a specific license option and must be updated in your contract. To learn more, refer to our [licensing docs](https://grafana.com/docs/grafana/latest/enterprise/license/license-restrictions/). To switch to combined user pricing, contact your Grafana Labs account team.

 ## Author dashboards faster with resource caching
 
 Your query editor just became faster. [Query caching](https://grafana.com/docs/grafana/latest/enterprise/query-caching/) improves query performance and sometimes reduces cost, by reducing the number of repetitive queries performed against data sources. Resource caching does the same thing but for resource calls, like retrieving the list of applications in the AppDynamics editor, the list of metrics from Datadog, or the list of values in a template variable dropdown. This makes for a zippier user experience for everyone writing queries in Grafana.
