Puppet 2023.0 is the latest release following 2021.7, now using updated versioning. It’s a backward-compatible release that contains enhancements and resolved issues from our previous major release.

Here are the highlights of Puppet Enterprise 2023.0:

  • NIST compliance: Puppet 2023.0 ensures that sensitive information is cleared when a session times out. You can customize the timeout to specify a default value and issue a confirmation message. In this way, you reduce compliance risk for InfoSecOps and administrators. This feature is designed for compliance with National Institute of Standards and Technology (NIST) guidelines.¬†

  • Authenticate users in multiple Lightweight Directory Access Protocol (LDAP) domains: Use a prioritized list of LDAP servers to get credentials. In this way, you reduce compliance risk and increase operational efficiency for administrators.¬†

  • Streamlined user interface for tasks and plans:¬†Increase observability, throughput, fault tolerance, and operational efficiency with new job and task queue status, task concurrency fine-tuning, default job timeouts, and the capability to stop stalled jobs. View and edit task parameters, targets, and other details. The new functionality is designed to benefit users, operators, and managers.¬†

  • Scalability performance improvements to deploy and manage more nodes: Increase operational efficiency and accelerate time to value with new orchestrator task concurrency defaults and improvements. Reporting, database performance, and agent certificate regeneration improvements are provided as well to benefit all users.¬†
