 * **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).
