## 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. Also the GetMetricData API pricing is different from GetMetricStatistics. While GetMetricStatistics qualified for the CloudWatch API free tier, this is not the case for GetMetricData calls. For more information, please refer to the CloudWatch pricing page (https://aws.amazon.com/cloudwatch/pricing/). Read more about GetMetricData limits in [upgrading to 6.5](https://grafana.com/docs/installation/upgrading/#upgrading-to-v6-5).
* **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 template variables as dimension values. When a multi 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 it might be the case that this limit is reached when a multi template variable that has a lot of values is being used. Read about the suggested workaround in [upgrading to 6.5](https://grafana.com/docs/installation/upgrading/#upgrading-to-v6-5).

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 (TPS). In this release, all queries use the GetMetricData API which has a limit of 50 TPS and 100 metrics per transaction. We expect this transition to be smooth for most of our users, but in case you do face throttling issues we suggest you increase the TPS quota. To do that, please visit the [AWS Service Quotas console](https://console.aws.amazon.com/servicequotas/home?r#!/services/monitoring/quotas/L-5E141212). For more details around CloudWatch API limits, [see CloudWatch docs](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/cloudwatch_limits.html).
Each request to the GetMetricData API can include 100 queries. This means that each panel in Grafana will only issue one GetMetricData request, regardless of the number of query rows that are present in the panel. Consequently as it is no longer possible to set `HighRes` on a per query level anymore, this switch is now removed from the query editor. High resolution can still be achieved by choosing a smaller minimum period in the query editor.
The handling of multi template variables in dimension values has been changed in Grafana 6.5. When a multi template variable is being used, Grafana will generate a search expression. In the GetMetricData API, expressions are limited to 1024 characters, so it might be the case that this limit is reached when a multi template variable that has a lot of values is being used. If this is the case, we suggest you start using `*` wildcard as dimension value instead of a multi template variable.
