# Amazon EMR 4.x release versions
<a name="emr-release-4x"></a>

This section contains application versions, release notes, component versions, and configuration classifications available in each Amazon EMR 4.x release version.

When you launch a cluster, you can choose from multiple releases of Amazon EMR. This allows you to test and use application versions that fit your compatibility requirements. You specify the release number with the *release label*. Release labels are in the form `emr-{{x.x.x}}`. For example, `emr-7.13.0`.

New Amazon EMR releases are made available in different Regions over a period of several days, beginning with the first Region on the initial release date. The latest release version may not be available in your Region during this period.

For a comprehensive table of application versions in every Amazon EMR 4.x release, see [Application versions in Amazon EMR 4.x releases](emr-release-app-versions-4.x.md).
