# Whats new in Grafana v8.3
Grafana 8.3 is an exciting release for Grafana Labs. This release includes the new Candlestick Panel, a new visualization suggestions engine and, for enterprise users, Recorded Queries.
For Open Source users it also marks the first time Grafana Alerting, formerly unified alerting, is enabled by default for new Grafana installations. Grafana Alerting in 8.3 is the flexible, single pane of glass for all your alerts. Included in this release is expanded provisioning support for notifiers, contact points, and alert rules, alongside auditing and fine-grained access control for our Enterprise customers.
Weve summarized whats new in the release here, but you might also be interested in the announcement blog post as well. If youd like all the details you can check out the complete [CHANGELOG.md](https://github.com/grafana/grafana/blob/master/CHANGELOG.md).
# Grafana OSS
## Accessibility
Weve continued to make progress on improving Grafanas accessibility. In Grafana 8.3 weve updated the main menu with improved keyboard navigation. Weve also improved Grafanas behavior when navigating through elements with the tab key (tab stops) and finished our work to make Grafanas 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.
## Dashboards and Visualizations
### Panel Suggestions
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].
# Grafana Enterprise
## Recorded Queries
Recorded queries turn “point in time” data into time series.
Recorded queries allow you to export the results of certain non-time series queries to the Enterprise backend in order to store data over time and allow customers to construct their own time series.
This new feature is especially helpful for Enterprise customers using plugins because many new plugins, like ServiceNow and Jira, dont return time series so customers werent able to plot historical data over time. With recorded queries, now they can! For more information
## Assign fine-grained permissions directly to users with the new role picker (beta)
Sometimes the Viewer, Editor, and Admin roles just dont 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)
Weve 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 Grafanas 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/).
## Get your encryption key from a Key Management Service
Grafanas database contains secrets, like the credentials used to query data sources, send alert notifications and perform other functions within Grafana. These secrets are encrypted using keys, which are usually stored in Grafanas configuration file. Now you can get your encryption key from Amazon KMS, Azure Key Vault, or Hashicorp Vault. This allows you to centrally manage your Grafana encryption key and reduce the chances it will leak.
In order to support this, weve upgraded Grafana Enterprise to use envelope encryption, which complements the KMS integration by adding a layer of indirection to the encryption process. Instead of encrypting all secrets with a single key, Grafana uses a set of keys called data encryption keys (DEKs) to encrypt them. These data encryption keys are themselves encrypted with a single key encryption key (KEK). With envelope encryption, you can store a KEK in your KMS, and still quickly encrypt and decrypt data using DEKs stored within the Grafana database.
## Pay the same for all users, regardless of their permissions
Are you tired of managing user permissions because your license only allows a certain number of Viewers and Editors or Admins? So were we. Weve 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.
## Review audit logs for more services, like alerting
[Audit logs](https://grafana.com/docs/grafana/latest/enterprise/auditing/) are a record of the actions users perform in Grafana, which you can investigate in case of a security incident or to understand Grafana usage better. Weve added audit logs for new actions performed against plugins, data sources, library elements, and Grafanas new alerting service. This ensures that if a user makes a change anywhere in Grafana Enterprise, youll have a record of it. For details, refer to the [Auditing docs](https://grafana.com/docs/grafana/latest/enterprise/auditing/).
