### Breaking changes
Grafana v8.2.0-beta1 caused data loss for users having enabled `ngalert` in 8.0.x - 8.1.x and created alerts using the new alerting system. This issue is now fixed except if the deployment has multiple organizations and the feature flag was enabled in the previous version (8.0.x - 8.1.x).
In this scenario (upgrade from 8.0.x - 8.1.x with multiple organizations and `ngalert` enabled to 8.2.0-beta2), the migration will assign existing notification policies and contact points to the first organization and then apply the default alertmanager configuration to all organizations. This will effectively reset notification policies for _all_ organizations. Issue [#39541](https://github.com/grafana/grafana/issues/39541)
### Deprecations
`ngalert` feature toggle it has been deprecated it will be removed in a future release. To enable Grafana 8 alerts, modify your configuration and:
- in the `unified_alerting` section set the `enabled` property to `true`
- in the `alerting` section set the `enabled` property to `false` Issue [#38746](https://github.com/grafana/grafana/issues/38746)
