## Update license restrictions
To increase the number of licensed users within Grafana, extend a license, or change your licensed URL, contact [Grafana support](https://grafana.com/profile/org#support) or your Grafana Labs account team. They will update your license, which you can activate from within Grafana.

Grafana 7.5 comes with alerting support for Loki. With LogQL you can wrap a log query with the functions that allow for creating metrics out of the logs, such as "rate()". Metric queries can then be used to calculate things such as the rate of error messages. [When combined with log parsers](https://www.youtube.com/watch?v=H9z2V0Ib1q0), they can be used to calculate metrics from a value within the log line, such latency or request size.
With alerting support for Loki, you can now create alerts on Loki metrics queries. Alert rules can be set up easily in the graph panel and you can learn more about the process of creating alerts in the Alert documentation.

### Cloudwatch data source enhancements
- Support for region eu-south-1 has been added to the CloudWatch data source. New metrics have also been added to the namespaces AWS/Timestream, AWS/RDS (RDS Proxy metrics), AWS/NetworkFirewall, AWS/GroundStation, and AWS/DDoSProtection. Many thanks to [relvira](https://github.com/relvira), [ilyastoli](https://github.com/ilyastoli), and [rubycut](https://github.com/rubycut) for contributing!
- You can now specify a custom endpoint in the CloudWatch data source configuration page. This field is optional, and if it is left empty, then the default endpoint for CloudWatch is used. By specifying a regional endpoint, you can reduce request latency.
### Increased API limit for CloudMonitoring Services
In previous versions, when querying metrics for Service Level Objectives (SLOs) in the CloudMonitoring data source, only the first 100 services were listed in the **Service** field list. To overcome this issue, the API limit for listing services has been increased to 1000.
## Enterprise features
These features are included in the Grafana Enterprise edition.
### Query caching
When caching is enabled, Grafana temporarily stores the results of data source queries. When you or another user submit the same query again, the results return from the cache instead of from the data source (such as Splunk or ServiceNow).
Query caching advantages:
- Faster dashboard load times, especially for popular dashboards.
- Reduced API costs.
- Reduced likelihood that APIs will rate-limit or throttle requests.
Caching currently works for all backend data sources. You can enable the cache globally or per data source, and you can configure the cache duration per data source. The cache is currently in-memory.
### Use template variable in reports
If you have created dashboards with template variables, then you can choose which values are selected when rendering a report. This makes it easier to tailor reports to their audience or generate multiple reports from the same dashboard.
Enable this feature in configuration settings using the `templateVariables` flag.
### Active user limits
If a Grafana instance has exceeded its licensed number of active users, then non-active users who try to sign in to Grafana will be prevented from doing so. Active users are users who have logged in to Grafana in the past 30 days. The total number of users registered in Grafana does not affect this rule. This enforcement is applied separately for Viewers and for Editor/Admins, so if you reach your active Viewer limit, new Editor/Admins will still be able to sign in. This rule also includes a 10% buffer, meaning that you need to exceed your limit by 10% before users are prevented from signing in.

### Query caching
If you enable this feature, then Grafana hashes and caches data source queries and serves cached versions of hashed queries if applicable.
### Use template variable in reports
If you enable the feature, then you can use template variables in reports.
### Tempo as a backend data source
We have converted Tempo to a backend data source and dropped support for tempo-query's (Jaeger) response. To configure, you can now point to the port that is set in Tempo's configuration file.
