1.9.0

• Customization request tracing - AFT now includes both the target account ID and a unique request ID in logs emitted during during Lambda-based account customization workflows. AFT also provisions 2 new CloudWatch Log Insights queries that can be used to find logs related to a customization request by the account ID or the customization request ID. These queries reduce troubleshooting effort by making it easier to identify where a failure is occurring.
• Concurrent account provisioning - AFT now supports provisioning new AWS accounts concurrently. The maximum concurrency is configurable via the new concurrent_account_factory_actions parameter. (default: 5, the default limit for AWS Control Tower Account Factory concurrent provisioning).
• Remove unneeded Lambda Layer dependencies, reducing build processing time by ~20%
• Bugfix: AFT now ignores unsupported Control Tower Events instead of sending failure notifications to the SNS topic
• Bugfix: Resolve an issue where the “aft-customizations-get-pipeline-executions” Lambda function did not have permissions to emit exceptions to the failure SNS topic.
