In this video, Nitish (Software Engineer at Akuity and Argo CD maintainer) walks through the Argo CD 3.4 release and highlights what’s new, what’s changing, and what you need to watch out for when upgrading. The focus of this release is “day-2 operations” — helping teams operate Argo CD at scale in real production environments. You’ll learn about key new features like cluster-wide reconciliation pause for incident response, ApplicationSet UI improvements, Microsoft Teams workflow migrations, Helm value file globbing, and major application list filtering upgrades. The video also covers important breaking changes, including cluster version formatting updates and behavioral changes in health reporting. Key Takeaways Argo CD 3.4 focuses on operating safely in production with features like cluster-wide reconciliation pause, better incident response controls, and improved observability for large environments. ApplicationSet now has a UI panel (behind a feature flag), Helm value file glob patterns simplify environment management, and application filtering is significantly more powerful. Teams must migrate Microsoft Teams notifications to Power Automate workflows, and adjust to Kubernetes version format changes and updated health status behavior to avoid automation issues.
