 ## v9.15.0
 
-Version 9.15.0 updates View Componment instrumentation to use a default metric name when one is unavailable, adds a configuration option to associate the AWS account ID with the DynamoDB calls from the AWS SDK, resolves a bug in rdkafka instrumentation when using the karafka-rdkafka gem, resolves a bug in the ruby-kafka instrumentation, fixes a bug with Grape instrumentation, and addresses a bug preventing the agent from running in serverless mode in an AWS Lambda layer.

 - **Feature: New configuration option cloud.aws.account_id**
 
-  A new configuration option has been added, `cloud.aws.account_id`, that will allow New Relic to provide more details about certain calls made using the AWS SDK. One example, is that relationships between AWS services instrumented with New Relic's CloudWatch Metric Streams will have relationships formed in the service map with APM applications. Currently, the DynamoDB instrumentation is the only instrumentation that will make use of this configuration option, but this will be used in future instrumentation as well. [PR#2904](https://github.com/newrelic/newrelic-ruby-agent/pull/2904)

             That configuration example uses YAML array syntax to specify both methods. Alternatively, you can use a comma-delimited string:

             Whitespace around the comma(s) in the list is optional. When configuring the agent with a list of methods via the `NEW_RELIC_AUTOMATIC_CUSTOM_INSTRUMENTATION_METHOD_LIST` environment variable, use this comma-delimited string format:
