# 6.7.0-beta1 (2020-03-12)
## Breaking changes
- **Slack**: Removed _Mention_ setting and instead introduce _Mention Users_, _Mention Groups_, and _Mention Channel_. The first two settings require user and group IDs, respectively. This change was necessary because the way of mentioning via the Slack API [changed](https://api.slack.com/changelog/2017-09-the-one-about-usernames) and mentions in Slack notifications no longer worked.
- **Alerting**: Reverts the behavior of `diff` and `percent_diff` to not always be absolute. Something we introduced by mistake in [6.1.0](https://github.com/grafana/grafana/commit/28eaac3a9c7082e8c496005c1cb66b4b70a4f82f). Alerting now support `diff()`, `diff_abs()`, `percent_diff()` and `percent_diff_abs()`. [#21338](https://github.com/grafana/grafana/pull/21338)
### Notice about changes in backendSrv for plugin authors
In our mission to migrate away from AngularJS to React we have removed all AngularJS dependencies in the core data retrieval service `backendSrv`.
Removing the AngularJS dependencies in `backendSrv` has the unfortunate side effect of AngularJS digest no longer being triggered for any request made with `backendSrv`. Because of this, external plugins using `backendSrv` directly may suffer from strange behaviour in the UI.
To remedy this issue, as a plugin author you need to trigger the digest after a direct call to `backendSrv`.
Another unfortunate outcome from this work in `backendSrv` is that the response format for `.headers()` changed from a function to an object.
To make your plugin work on 6.7.x as well as on previous versions you should add something like the following:
```typescript
let responseHeaders = response.headers;
if (!responseHeaders) {
return null;
}
// Support pre 6.7 angular HTTP rather than fetch
if (typeof responseHeaders === 'function') {
responseHeaders = responseHeaders();
}
```
You can test your plugin with the `master` branch version of Grafana.

## Breaking changes
- **CloudWatch**: Pre Grafana 6.5.0, the CloudWatch datasource used the GetMetricStatistics API for all queries that did not have an ´id´ and did not have an ´expression´ defined in the query editor. The GetMetricStatistics API has a limit of 400 transactions per second. In this release, all queries use the GetMetricData API. The GetMetricData API has a limit of 50 transactions per second and 100 metrics per transaction. For API pricing information, please refer to the CloudWatch pricing page (https://aws.amazon.com/cloudwatch/pricing/).
- **CloudWatch**: The GetMetricData API does not return metric unit, so unit auto detection in panels is no longer supported.
- **CloudWatch**: The `HighRes` switch has been removed from the query editor. Read more about this in [upgrading to 6.5](https://grafana.com/docs/installation/upgrading/#upgrading-to-v6-5).
- **CloudWatch**: In previous versions of Grafana, there was partial support for using multi-valued template variables as dimension values. When a multi-valued template variable is being used for dimension values in Grafana 6.5, a [search expression](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/using-search-expressions.html) will be generated. In the GetMetricData API, expressions are limited to 1024 characters, so you might reach this limit if you are using a large number of values. Read our [upgrading to 6.5](https://grafana.com/docs/installation/upgrading/#upgrading-to-v6-5) guide to see how you can use the `*` wildcard for this use case.

- **CloudWatch**: Pre Grafana 6.5.0, the CloudWatch datasource used the GetMetricStatistics API for all queries that did not have an ´id´ and did not have an ´expression´ defined in the query editor. The GetMetricStatistics API has a limit of 400 transactions per second. In this release, all queries use the GetMetricData API. The GetMetricData API has a limit of 50 transactions per second and 100 metrics per transaction. For API pricing information, please refer to the CloudWatch pricing page (https://aws.amazon.com/cloudwatch/pricing/).
- **CloudWatch**: The GetMetricData API does not return metric unit, so unit auto detection in panels is no longer supported.
- **CloudWatch**: The `HighRes` switch has been removed from the query editor. Read more about this in [upgrading to 6.5](https://grafana.com/docs/installation/upgrading/#upgrading-to-v6-5).
- **CloudWatch**: In previous versions of Grafana, there was partial support for using multi-valued template variables as dimension values. When a multi-valued template variable is being used for dimension values in Grafana 6.5, a [search expression](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/using-search-expressions.html) will be generated. In the GetMetricData API, expressions are limited to 1024 characters, so you might reach this limit if you are using a large number of values. Read our [upgrading to 6.5](https://grafana.com/docs/installation/upgrading/#upgrading-to-v6-5) guide to see how you can use the `*` wildcard for this use case.

## Breaking changes
### Annotations
There are some breaking changes in the annotations HTTP API for region annotations. Region annotations are now represented
using a single event instead of two separate events. Check breaking changes in HTTP API [below](#http-api) and [HTTP API documentation](https://grafana.com/docs/http_api/annotations/) for more details.
### Docker
Grafana is now using Alpine 3.10 as docker base image.
### HTTP API
-`GET /api/alert-notifications` now requires at least editor access. New `/api/alert-notifications/lookup` returns less information than `/api/alert-notifications` and can be access by any authenticated user.
-`GET /api/alert-notifiers` now requires at least editor access
-`GET /api/org/users` now requires org admin role. New `/api/org/users/lookup` returns less information than `/api/org/users` and can be access by users that are org admins, admin in any folder or admin of any team.
-`GET /api/annotations` no longer returns `regionId` property.
-`POST /api/annotations` no longer supports `isRegion` property.
-`PUT /api/annotations/:id` no longer supports `isRegion` property.
-`PATCH /api/annotations/:id` no longer supports `isRegion` property.
-`DELETE /api/annotations/region/:id` has been removed.
## Deprecation notes
### PhantomJS
[PhantomJS](https://phantomjs.org/), which is used for rendering images of dashboards and panels, is deprecated and will be removed in a future Grafana release. A deprecation warning will from now on be logged when Grafana starts up if PhantomJS is in use.
Please consider migrating from PhantomJS to the [Grafana Image Renderer plugin](https://grafana.com/grafana/plugins/grafana-image-renderer).

### Removal of old deprecated package repository
5 months ago we deprecated our old package cloud repository and [replaced it](https://grafana.com/blog/2019/01/05/moving-to-packages.grafana.com/) with our own. We will remove the old depreciated
repo on July 1st. Make sure you have switched to the new repo by then. The new repository has all our old releases so you are not required to upgrade just to switch package repository.

### Breaking changes
- **Text Panel**: The text panel does no longer by default allow unsanitized HTML. [#4117](https://github.com/grafana/grafana/issues/4117). This means that if you have text panels with scripts tags they will no longer work as before. To enable unsafe javascript execution in text panels enable the settings `disable_sanitize_html` under the section `[panels]` in your Grafana ini file, or set env variable `GF_PANELS_DISABLE_SANITIZE_HTML=true`.
- **Dashboard**: Panel property `minSpan` replaced by `maxPerRow`. Dashboard migration will automatically migrate all dashboard panels using the `minSpan` property to the new `maxPerRow` property [#12991](https://github.com/grafana/grafana/pull/12991)
