+
+## Highlights
+
+Grafana 6.6 comes with a lot of new features and enhancements:
+
+- **Panels:** New Stat panel
+- **Panels:** New News panel
+- **New time picker**
+- **User-configurable units**
+- [**Alerting enhancements**]({{< relref "#alerting-enhancements" >}})
+- **Explore:** Added log message line wrapping options for logs
+- **Graphite:** Added Metrictank dashboard to Graphite datasource
+- **Loki:** Support for template variable queries
+- **Postgres/MySQL/MSSQL:** Added support for region annotations
+- **Explore:** Added ability to specify step with Prometheus queries
+- [**Security:** Added disabled option for cookie samesite attribute]({{< relref "#cookie-management-modifications" >}})
+- **TablePanel, GraphPanel:** Exclude hidden columns from CSV
+
+More details will be added as we're getting closer to the stable release.
+
+## Alerting enhancements
+
+ - We have introduced a new configuration for enforcing a minimal interval between evaluations, to reduce load on the backend. 
+ - The email notifier can now optionally send a single email to all recipients. 
+ - OpsGenie, PagerDuty, Threema, and Google Chat notifiers have been updated to send additional information.
+
+## Cookie management modifications
+
+In order to align with a [change in Chrome 80](https://www.chromestatus.com/feature/5088147346030592), a breaking change has been introduced. The `[security]` setting `cookie_samesite` configured to `none` now renders cookies with `SameSite=None` attribute contrary to the previous behavior where no `SameSite` attribute was added to cookies. To get back the old behavior, you must set `cookie_samesite` to `disabled`.
