 ### New Logs Panel
-A new panel specifically to show logs is added in this release. It’s in early alpha state so you have to enable alpha panels (in config file) to be able to try it out.
+The logs panel shows log lines from datasources that support logs, e.g., Elastic, Influx, and Loki. Typically you would use this panel next to a graph panel to display the log output of a related process.
+<img src="/img/docs/v64/logs-panel.png" />
+Limitations: Even though Live tailing can be enabled on logs panels in dashboards, we recommend using Live tailing in Explore. On dashboards, the refresher at the top of the page should be used instead to keep the data of all panels in sync. Note that the logs panel is still beta and we're looking to get feedback.

+## Series override to turn constant into a line
+Some graph query results are made up only of one datapoint per series but can be shown in the graph panel with the help of [series overrides](/features/panels/graph/#series-overrides).
+To show a horizontal line through the Y-value of the datapoint across the whole graph, add a series override and select `Transform > constant`.

 ## Share query results between panels
 Grafana 6.4 continues the work started in 6.3 of creating a data model and query execution lifecycle that can support robust analytics and streaming.  These changes are mostly structural and lay the foundation for powerful features in future releases.

 You can read more about the grafana-toolkit [in the Readme](https://github.com/grafana/grafana/blob/master/packages/grafana-toolkit/README.md) and play with it by trying out our [react panel](https://github.com/grafana/simple-react-panel) or [angular panel](https://github.com/grafana/simple-angular-panel) templates.
-## Query over multiple resources in Azure Monitor
-Up until now it has only been possible to query over one resource in one subscription in the Azure Monitor datasource. In Grafana 6.4, the Azure Monitor query editor contains a new option called Query Mode which allows for querying over multiple resources in multiple subscriptions. This can be very useful in many situations, e.g cpu credits consumed by all virtual machines over many subscriptions.
-Alerting is yet to be implemented for Multiple Resources queries.
 ## PhantomJS deprecation
 [PhantomJS](https://phantomjs.org/), which is used for rendering images of dashboards and panels, have been deprecated and will be removed in a future Grafana release. A deprecation warning will from now on be logged when Grafana starts up if PhantomJS is in use.
