Updates one or more properties of an annotation that matches the specified id.
This operation currently supports updating of the `text`, `tags`, `time` and `timeEnd` properties. It does not handle updating of the `isRegion` and `regionId` properties. To make an annotation regional or vice versa, consider using the [Update Annotation](#update-annotation) operation.

## Delete Annotation By RegionId
`DELETE /api/annotations/region/:id`
Deletes the annotation that matches the specified region id. A region is an annotation that covers a timerange and has a start and end time. In the Grafana database, this is a stored as two annotations connected by a region id.
**Example Request**:
```http
DELETE /api/annotations/region/1 HTTP/1.1

If you have text panels with script tags they will no longer work due to a new setting that per default disallow unsanitized HTML.
Read more [here](/installation/configuration/#disable-sanitize-html) about this new setting.
## Upgrading to v6.4
One of the database migrations included in this release will merge multiple rows used to represent an annotation range into a single row. If you have a large number of region annotations the database migration may take a long time to complete. See [Upgrading to v5.2](#upgrading-to-v5-2) for tips on how to manage this process.
