PE 2023.8.12

Released October 2026

Puppet Enterprise (PE) 2023.8.12 expands platform support, resolves an issue that could cause orchestrator tasks to return incorrect results after an orchestrator reboot, and includes fixes for multiple security vulnerabilities.

Puppet Enterprise® lifecycle update

Starting in August 2026, Puppet Enterprise transitioned its software support model from Long-Term Support (LTS) and Short-Term Support (STS) to the Latest and Latest-1 model. This change applies to both PE and PE Advanced. To learn more, see Puppet Enterprise Platform Support Lifecycle.

Puppet Enterprise (PE) 2023.8.x is the final release series under Puppet Enterprise's Long-Term Support (LTS) model. Future major releases follow the Latest / Latest - 1 support model introduced with PE 2026.0.
To access the release notes for the Puppet® platform, including Puppet agent, Puppet Server, Facter, and PuppetDB, see Platform release notes.

Platform support

Agent platforms added

This release adds support for the Puppet agent on the following operating system platforms:

  • AlmaLinux 10

  • Rocky Linux 10

  • Ubuntu 26.04 AMD

  • Ubuntu 26.04 ARM

Resolved issues

Orchestrator tasks no longer return incorrect results

In previous versions of PE, after an orchestrator reboot, agents could return cached data instead of running the requested task. This could cause jobs to report inaccurate results. This issue is resolved in PE 2023.8.12, 2025.12.0, and 2026.0. [PE-46864]
