PE 2025.10

Puppet Enterprise^® (PE and PE Advanced) lifecycle update—Puppet is transitioning its Puppet Enterprise^® software support offerings from the “Long Term Support” and “Short Term Support” model to the "Latest" and "Latest - 1" model.

Starting August 6, 2026, Puppet Enterprise^® will adopt a new software support model using the following nomenclature of “Latest” and “Latest - 1” that will accelerate product innovation and simplify the product lifecycle management.

What’s changing?

Under the new model:

• “Latest” series: Receives full software support and maintenance (new features, fixes, security updates) for 12 months from the date of the latest major version release.

• “Latest - 1” series: Receives limited software support and maintenance (security updates, defect fixes, and minor changes only) for an additional 12 months after being superseded by the “Latest” version of the Puppet Enterprise^® software.

The new model will replace the previous Long-Term Support (“LTS”) model, which offered up to twenty-four (24) months of limited software support and maintenance with limited feature delivery.

Impact on current release streams:

• PE 2023.8.z series (LTS): This is the final series supported under the LTS support model. Maintenance releases will continue until August 2026, when the series reaches end of life (“EOL”). This timing coincides with the launch of the new software and support lifecycle model. Customers should begin planning upgrades to remain supported.

• PE 2025.y series (Current “latest”): This series will continue receiving the latest updates until August 2026, when the next major PE version is released. At that point, 2025.y will transition to “Latest -1” and receive security updates, defect fixes, and minor changes only until its EOL in August 2027.

This change is designed to:

• Deliver continuous access to new features

• Improve security through more frequent updates and patches

• Provide a predictable, simplified support timeline

Further documentation and upgrade guidance will be provided ahead of the August 2026 transition.
