You can now choose to have your AWS Elastic Beanstalk environments automatically update to the latest version of the underlying platform running your application during a specified maintenance window. Elastic Beanstalk regularly releases new versions of supported platforms (i.e., Java, PHP, Ruby, Node.js, Python, .NET, Go, and Docker) with operating system, web & application server, and language & framework updates. Previously, you had to manually initiate updates to your Elastic Beanstalk environments using the Elastic Beanstalk console, command line interface (CLI), or API. Now, you can simply select a weekly maintenance window and have Elastic Beanstalk automatically update the platform version of your environment during that window.
