You can now use the AWS Elastic Beanstalk ListPlatformBranches API action that lists available Elastic Beanstalk platform branches and provides summary information about each platform branch. You can use the API action to query the platform state (Supported, Beta, Deprecated, Retired) of your Elastic Beanstalk environment. For more information on Platform Branch state, see Elastic Beanstalk Platforms Glossary in the AWS Elastic Beanstalk Developer Guide. For details about the ListPlatformBranches API action, see ListPlatformBranches in the AWS Elastic Beanstalk API Reference. See Release Notes for additional details.
