Puppet Enterprise support lifecycle

Puppet Enterprise (PE) follows the Latest and Latest-1 support model. This model replaces the previous Long-Term Support (LTS) and Short-Term Support (STS) release tracks.

The Latest release series is the leading-edge PE release stream and contains the most recent major version of Puppet Enterprise.

For detailed information about Puppet Enterprise release tracks, support status, maintenance timelines, upgrade recommendations, end-of-maintenance dates, and component support lifecycles, see the Puppet Enterprise lifecycle policy.

If the latest release with the most up-to-date features is right for you, download or try the latest PE release, or download an older supported release from the Previous Releases page. We recommend following our Install guide and understanding the System requirements before downloading the installation package.

Open source tools and libraries

PE uses open source tools and libraries. We use both externally maintained components, such as Ruby, PostgreSQL, and JVM, and projects we own and maintain, such as Facter, Puppet agent, Puppet Server, and PuppetDB.

Projects we own and maintain are "upstream" of our commercial releases. Our open source projects move faster and have shorter support life cycles than PE. We might discontinue updates to our open source platform components before their commercial EOL dates. We vet upstream security and feature releases and update supported versions according to customer demand and our Security policy.
