### Deprecations
AngularJS plugin support is now in a deprecated state, meaning it will be removed in a future release. Currently, that is planned for version 10 (in 2023). The documentation site has an [article](https://grafana.com/docs/grafana/next/developers/angular_deprecation/) with more details on why, when, and how.
