[Puppet Product Updates]

Puppet Core 8.18.0 is now available

We’re pleased to announce the availability of Puppet Core 8.18.0. This release brings new macOS platform support alongside important security updates that help ensure a stable, well maintained automation foundation. 

Puppet Core releases are designed to help you stay current without adding operational overhead. Version 8.18.0 continues that approach by pairing platform coverage updates with tested dependency upgrades delivered through vendor-backed builds. 

What’s new  

Support for macOS 15 
Puppet Core now supports macOS 15 on both x86_64 and ARM architectures. This enables continued management of macOS systems using the same automation controls and policies you already rely on. 

Security focused dependency updates 
This release includes updates to several bundled components to address recently disclosed security vulnerabilities. By delivering these updates as part of hardened Puppet Core builds, you reduce dependency risk without tracking, validating, or rebuilding components independently. 

Why upgrade? 

Upgrading to Puppet Core 8.18.0 helps you: 

• Take advantage of the latest platform support. 
• Reduce exposure to dependency related security risk. 
• Rely on vendor tested packages instead of managing updates yourself.
