Support Lifecycle

The Puppet Support Lifecycle policy provides guidelines throughout the lifecycle of each version of Puppet Enterprise. Puppet Enterprise versions are in one of three phases of the Puppet Support Lifecycle. These phases are:

  • Mainstream support: Puppet Enterprise versions in this phase receive security updates, bug fixes and technical support as defined in the support plan. Customers on current support plans can access all services from Customer Support, including the authenticated FAQ, the customer support portal and other customer-facing resources.
  • Limited support: Puppet Enterprise versions in this phase are no longer eligible for security updates and bug fixes. Customers on valid support plans can access services from Customer Support, receive SLA response times and utilize the other customer-facing resources listed above. Puppet assists customers in upgrading to the current mainstream supported version(s).
  • End-of-life (EOL): Puppet Enterprise versions in this phase are no longer eligible for security updates, bug fixes, or anything other than "commercially reasonable" assistance from Customer Support. Customers in the process of upgrading to a fully-supported version may contact support and utilize other support resources. 

Puppet produces a standard release approximately every three months. Mainstream support for standard releases ends when the next version is released.  

Puppet releases a new long term support (LTS) release every 18 months. An LTS release receives mainstream support for 24 months after launch. This includes a series of "z" or maintenance releases so customers always have access to the latest security updates.

Projects which Puppet owns and maintains, like Facter, the Puppet Agent and Server, and PuppetDB will move faster and have shorter maintenance lifecycles than Puppet Enterprise. We may discontinue updates to the open source versions of platform components before their Puppet Enterprise EOL dates. 

Puppet provides either mainstream or limited support for the versions of Puppet Enterprise listed below. All versions older than Puppet Enterprise 3.8 are now End-of-life (EOL) and we encourage upgrading to the latest version.
