Amazon is updating the TLS configuration for all Amazon API endpoints to a minimum version of TLS 1.2. Amazon EMR release 4.0.0 only supports TLS 1.0/1.1 connections. After December 4, 2023, you won't be able to create clusters with the emr-4.0.0 release label.

If you use Amazon EMR 4.0.0, we recommend that you immediately test and migrate your workloads to the latest Amazon EMR release. For more information, see the Amazon Security Blog.

Release notes

Component versions

The components that Amazon EMR installs with this release are listed below. Some are installed as part of big-data application packages. Others are unique to Amazon EMR and installed for system processes and features. These typically start with emr or aws. Big-data application packages in the most recent Amazon EMR release are usually the latest version found in the community. We make community releases available in Amazon EMR as quickly as possible.

Some components in Amazon EMR differ from community versions. These components have a version label in the form CommunityVersion-amzn-EmrVersion. The EmrVersion starts at 0. For example, if open source community component named myapp-component with version 2.2 has been modified three times for inclusion in different Amazon EMR releases, its release version is listed as 2.2-amzn-2.
