<a name="release-2021-12-21-linux"></a>

**Release date:** December 21, 2021

## Changes
<a name="release-2021-12-21-linux.changes"></a>

The following table lists the changes included in this release.

**Important**  
Elastic Beanstalk installs Log4j from the Amazon Linux default package repositories in its Tomcat platforms for Amazon Linux 1 and Amazon Linux 2. The versions of Log4j available in the Amazon Linux 1 and Amazon Linux 2 repositories are not affected by [CVE-2021-44228](https://www.cve.org/CVERecord?id=CVE-2021-44228) or [CVE-2021-45046](https://www.cve.org/CVERecord?id=CVE-2021-45046) in their default configuration.  
*If you've made configuration changes to your application’s use of log4j, or installed newer versions of log4j, then we recommend that you take action to update your application’s code to mitigate this issue.*  
Out of caution, Elastic Beanstalk is releasing new platform versions that use the latest Amazon Linux default package repositories, which include the [Log4j hotpatched JDK](https://aws.amazon.com/blogs/opensource/hotpatch-for-apache-log4j/), in today's release. If you've customized log4j installation as your application dependency, we recommend that you upgrade to the latest Elastic Beanstalk platform version to mitigate CVE-2021-44228 or CVE-2021-45046. You can also enable automated managed updates as part of normal update practices.  
For more information about security-related software updates for Amazon Linux, see the [Amazon Linux Security Center](https://alas.aws.amazon.com/).

**Notes**  
These release notes focus on changes to currently supported platform branches. For full version information of Elastic Beanstalk retiring (deprecated) platform branches, see [Elastic Beanstalk platform versions scheduled for retirement](https://docs.aws.amazon.com/elasticbeanstalk/latest/platforms/platforms-retiring.html) in the *AWS Elastic Beanstalk Platforms* guide.
Be aware that at the time these release notes are published, the new platform versions might not yet be available in all the AWS Regions that Elastic Beanstalk supports. It might take a few hours for the release to complete.
