 You can create new annotation queries that fetch annotations from the native annotation store via the `-- Grafana --` data source and by setting *Filter by* to `Tags`. Specify at least
 one tag. For example create an annotation query name `outages` and specify a tag named `outage`. This query will show all annotations you create (from any dashboard or via API) that have the `outage` tag. By default, if you add multiple tags in the annotation query, Grafana will only show annotations that have all the tags you supplied. You can invert the behavior by enabling `Match any` which means that Grafana will show annotations that contains at least one of the tags you supplied.
 
-In 5.4+ it's possible to use template variables in the tag query. So if you have a dashboard showing stats for different services and an template variable that dictates which services to show, you can now use the same template variable in your annotation query to only show annotations for those services.
