This topic includes the release notes for the Grafana v6.7. For all details, read the full [CHANGELOG.md](https://github.com/grafana/grafana/blob/master/CHANGELOG.md).
Query history is a new feature that lets you view and interact with the queries that you have previously run in Explore. You can add queries to the Explore query editor, write comments, create and share URL links, star your favorite queries, and much more. Starred queries are displayed in Starred tab, so it is easier to reuse queries that you run often without typing them from scratch.
Grafana v6.7 comes with a new OAuth integration for Microsoft Azure Active Directory. You can now assign users and groups to Grafana roles from the Azure Portal. Learn how to enable and configure it in [Azure AD OAuth2 authentication]({{< relref "../auth/azuread/" >}}).
Allowing a low dashboard refresh interval can cause severe load on data sources and Grafana. Grafana v6.7 allows you to restrict the dashboard refresh interval so it cannot be set lower than a given interval. This provides a way for administrators to control dashboard refresh behavior on a global level.
Refer to min_refresh_interval in [Configuration]({{< relref "../administration/configuration#min-refresh-interval" >}}) for more information and how to enable this feature.
A Stackdriver data source in Grafana is configured for one service account only. That service account is always associated with a default project in Google Cloud Platform (GCP). Depending on your setup in GCP, the service account might be granted access to more projects than just the default project.
In Grafana 6.7, the query editor has been enhanced with a project selector that makes it possible to query different projects without changing datasource. Many thanks [Eraac](https://github.com/Eraac), [eliaslaouiti](https://github.com/eliaslaouiti), and [NaurisSadovskis](https://github.com/NaurisSadovskis) for making this happen!
This release adds a new white labeling option to customize the application title. Learn how to configure it in [White labeling]({{< relref "../enterprise/white-labeling/" >}}).
### Configure reporting for timeout and concurrency
This release adds more configuration for the reporting feature rendering requests. You can set the panel rendering request timeout and the maximum number of concurrent calls to the rendering service in your configuration. Learn how to do it in [Reporting]({{< relref "../enterprise/reporting/" >}}).
This feature allows you to export a dashboard as a PDF document. All dashboard panels will be rendered as images and added into the PDF document. Learn more in [Export dashboard as PDF]({{< relref "../enterprise/export-pdf/" >}}).
