Amazon AppConfig User Guide document history
The following table describes the important changes to the documentation since the last release of Amazon AppConfig.
Current API version: 2019-10-09
| Change | Description | Date |
|---|---|---|
New version of Amazon AppConfig Agent Lambda extension | The agent has been updated to support feature flag targets, variants, and splits. To view the new Amazon Resource Names (ARNs) for the extension, see Available versions of the Amazon AppConfig Agent Lambda extension. | July 23, 2024 |
New feature: Multi-variant feature flags | Multi-variant feature flags enable you to define a set of possible flag values to return for a request. You can also configure different statuses (enabled or disabled) for multi-variant flags. When requesting a flag configured with variants, your application provides context that Amazon AppConfig evaluates against a set of user-defined rules. Depending on the context specified in the request and the rules defined for the variant, Amazon AppConfig returns different flag values to the application. For more information, see Creating multi-variant feature flags. | July 23, 2024 |

Amazon CloudFormation support for new Amazon AppConfig resources and a feature flag example | Amazon CloudFormation now supports the AWS::AppConfig::Extension and AWS::AppConfig::ExtensionAssociation resources to help you get started with Amazon AppConfig extensions. The AWS::AppConfig::ConfigurationProfile and AWS::AppConfig::HostedConfigurationVersion resources now include an example for creating a feature flag configuration profile in the Amazon AppConfig hosted configuration store. | April 12, 2023 |
Amazon AppConfig integration with Amazon Secrets Manager | Amazon AppConfig integrates with Amazon Secrets Manager. Secrets Manager helps you to securely encrypt, store, and retrieve credentials for your databases and other services. Instead of hardcoding credentials in your apps, you can make calls to Secrets Manager to retrieve your credentials whenever needed. Secrets Manager helps you protect access to your IT resources and data by enabling you to rotate and manage access to your secrets. When you create a freeform configuration profile, you can choose Secrets Manager as the source of your configuration data. You must onboard with Secrets Manager and create a secret before you create the configuration profile. For more information about Secrets Manager, see What is Amazon Secrets Manager? in the Amazon Secrets Manager User Guide. For information about creating a configuration profile, see Creating a freeform configuration profile. | February 2, 2023 |
Amazon AppConfig integration with Amazon ECS and Amazon EKS | You can integrate Amazon AppConfig with Amazon Elastic Container Service (Amazon ECS) and Amazon Elastic Kubernetes Service (Amazon EKS) by using the Amazon AppConfig agent.

The agent enhances containerized application processing and management in the following ways:
For more information, see Amazon AppConfig integration with Amazon ECS and Amazon EKS. | December 2, 2022 |
New extension: Amazon AppConfig extension for CloudWatch Evidently | You can use Amazon CloudWatch Evidently to safely validate new features by serving them to a specified percentage of your users while you roll out the feature. You can monitor the performance of the new feature to help you decide when to ramp up traffic to your users. This helps you reduce risk and identify unintended consequences before you fully launch the feature. You can also conduct A/B experiments to make feature design decisions based on evidence and data. The Amazon AppConfig extension for CloudWatch Evidently allows your application to assign variations to user sessions locally instead of by calling the EvaluateFeature operation. A local session mitigates the latency and availability risks that come with an API call. For information about how to configure and use the extension, see Perform launches and A/B experiments with CloudWatch Evidently in the Amazon CloudWatch User Guide. | September 13, 2022 |

Each Jira issue includes the flag name, application ID, configuration profile ID, and flag values. After you update, save, and deploy your flag changes, Jira updates the existing issues with the details of the change. For more information, see Amazon AppConfig integration with Atlassian Jira. | April 7, 2022 |
General availability of feature flags and Lambda extension support for ARM64 (Graviton2) processors | With Amazon AppConfig feature flags, you can develop a new feature and deploy it to production while hiding the feature from users. You start by adding the flag to Amazon AppConfig as configuration data. Once the feature is ready to be released, you can update the flag configuration data without deploying any code. This feature improves the safety of your dev-ops environment because you don't need to deploy new code to release the feature. For more information, see Creating a feature flag configuration profile. General availability of feature flags in Amazon AppConfig includes the following enhancements:
