Puppet 8 was released in April 2023, with Puppet 7 reaching end-of-life on February 28, 2025. Key updates include improvements in developer tools, agent compatibility, and the deprecation of legacy facts in Facter. Notable enhancements in Puppet Server include support for machines with over 2TB, a new bulk certificate signing endpoint, and the dropping of Java 8 support in favor of Java 17.
