As part of the new alert changes, we have introduced a new data source, Alertmanager, which includes built-in support for Prometheus Alertmanager. It is presently in alpha and it not accessible unless alpha plugins are enabled in Grafana settings. For more information, refer to [Alertmanager data source]({{< relref "../datasources/alertmanager.md" >}}).
> **Note:** Out of the box, Grafana still supports old Grafana alerts. They are legacy alerts at this time, and will deprecated in a future release.

### State timeline visualization (beta)
The State timeline visualization shows discrete state changes over time. Each field or series is rendered as a unique horizontal band. This panel works well with string or boolean states, but it can also be used with time series data. When used with time series data, the thresholds are used to turn the numerical values into discrete state regions.

### Status grid visualization (beta)
This new visualization is designed to display periodic status history.
A sister panel to the state timeline is the new Status grid panel visualization. It can display periodic state in a grid. Works with both numerical, string or boolean state.

### Histogram visualization (beta)
This release introduces a new histogram panel visualization.
This hidden feature of the old Graph panel is now a standalone visualization. It combines a histogram transformation and bar chart visualization into a single, integrated, easy-to-use panel. There is also a new standalone histogram transformation that can be paired with any visualization.

- Better Jaeger search in Explore
- Show trace graph for Jaeger, Zipkin, and Tempo
### Plugin catalog
You can now use the Plugin catalog app to easily manage your plugins from within Grafana. Install, update, and uninstall plugins without requiring a server restart.
[Plugin catalog]({{< relref "../plugins/catalog.md" >}}) was added as a result of this feature.
### Performance improvements

### Fine-grained access control
You can now add or remove detailed permissions from Viewer, Editor, and Admin org roles, to grant users just the right amount of access within Grafana. Available permissions include the ability to view and manage Users, Reports, and the Access Control API itself. Grafana will support more and more permissions over the coming months. See the [Fine-grained access control docs]({{< relref "../enterprise/access-control/_index.md" >}}) for more details.

[Fine-grained access control docs]({{< relref "../enterprise/access-control/_index.md" >}}) were added as a result of this feature.
### Data source query caching
Grafana will now cache the results of backend data source queries, so that multiple users viewing the same dashboard or panel will not each submit the same query to the data source (like Splunk or Snowflake) itself. This results in faster average load times for dashboards and fewer duplicate queries overall to data sources, which reduces cost and the risk of throttling, reaching API limits, or overloading your data sources. Caching can be enabled per-data source, and time-to-live (TTL) can be configured globally and per data source. Query caching can be set up with Redis, Memcached, or a simple in-memory cache. See the [Data source query caching docs]({{< relref "../enterprise/query-caching.md" >}}) for more details.

### Reporting updates
When creating a report, you can now choose to export Table Panels as .csv files attached to your report email. This will make it easier for recipients to view and work with that data. You can also link back to the dashboard directly from the email, for users who want to see the data live in Grafana. This release also includes some improvements to the Reports list view. See the [Reporting docs]({{< relref "../enterprise/reporting.md" >}}) for more details.

### License restrictions clarification in the docs
The docs have been updated to describe more specifically how licensed roles are counted, how they can be updated, and where you can see details about dashboard and folder permissions that affect users' licensed roles. Visit the [License restrictions docs]({{< relref "../enterprise/license/license-restrictions.md" >}}) for details.
