5.10.0 Release Notes

Overview

Official Support for Java 17

Rundeck and Enterprise Runners on version 5.10.0 now support Java 17 runtime (JRE), bringing significant advantages to enterprise customers through its Long Term Support (LTS) status and enhanced performance capabilities. With Java 17 LTS support extending until September 2029, organizations can confidently deploy Rundeck knowing they have a stable, supported foundation for years to come. The upgrade delivers notable performance improvements through enhanced G1 Garbage Collection, resulting in more predictable pause times and better memory management. Users will experience faster startup times and reduced memory footprint, particularly beneficial for containerized deployments and cloud environments. Existing Rundeck deployments running on Java 11 can be upgraded seamlessly to Java 17, maintaining backward compatibility with existing automation workflows and custom plugins.

Note: Building from source still requires Java 11 JDK

Enhanced Runner Install Experience

Enterprise Runners provide the crucial mechanism for securely dispatching automation to infrastructure within your environments. As Runners are regularly created by both new and existing users, the installation experience is critical for reducing the time to get up and running with Runbook Automation. With this latest release, we have significantly improved the process to create and install new Runners. Users now select the platform type for their Runners – such as Linux, Windows, Docker or Kubernetes – and then they are presented with the necessary commands to immediately install the Runner of the chosen type. This significantly reduces the steps required to stand up new Runners and enables new teams to get started within their Runbook Automation Projects with greater ease.
