### Cloudwatch data source enhancements
- Support for region eu-south-1 has been added to the CloudWatch data source. New metrics have also been added to the namespaces AWS/Timestream, AWS/RDS (RDS Proxy metrics), AWS/NetworkFirewall, AWS/GroundStation, and AWS/DDoSProtection. Many thanks to [relvira](https://github.com/relvira), [ilyastoli](https://github.com/ilyastoli), and [rubycut](https://github.com/rubycut) for contributing!
- Added a page limit to the List Metrics API call to improve speed and reduce memory consumption. You can change this limit by entering a higher value in [list_metrics_page_limit]({{< relref "../administration/configuration.md#list-metrics-page-limit" >}}) in the Grafana configuration file.
- You can now enable or disable authentication providers and assume a role other than default by changing the [allowed_auth_providers]({{< relref "../administration/configuration.md#allowed-auth-providers" >}}) and [assume_role_enabled]({{< relref "../administration/configuration.md#assume-role-enabled" >}}) options in the Grafana configuration file. By default, the allowed authentication providers are _AWS SDK Default_, _Access && secret key_, and _Credentials File_, and role is _Assume role (ARN)_.
- You can now specify a custom endpoint in the CloudWatch data source configuration page. This field is optional, and if it is left empty, then the default endpoint for CloudWatch is used. By specifying a regional endpoint, you can reduce request latency.
[AWS Cloudwatch data source]({{< relref "../datasources/cloudwatch.md#endpoint" >}}) was updated as a result of this change.
