Helm Celebrates a Decade of Innovation With Launch of Version 4 Upgrade
Helm Celebrates 10 Years with Helm Version 4 Launch
On November 12, 2025, the Cloud Native Computing Foundation (CNCF) unveiled Helm Version 4, commemorating the project's tenth anniversary. This significant update, the first in six years, aims to streamline and enhance the deployment and management of Kubernetes applications, addressing many of the complexities faced by users in the cloud-native landscape.
As Kubernetes has evolved, so too have the challenges of deploying applications at scale. Data from the CNCF's 2024 Annual Survey revealed that a notable 40% of users see CI/CD complexity as a major obstacle, while 37% consider security a critical barrier to wider adoption. Helm 4 is positioned to tackle these pressing issues head-on by offering improved testing automation, enhanced chart signing, better performance, and streamlined chart distribution. These upgrades are essential in assisting development teams to deliver software more rapidly and securely.
Chris Aniszczyk, the CTO of CNCF, emphasized the significance of this update, stating, "Helm 4 is the result of ten years of community insight and real-world deployment lessons. As teams embrace cloud-native scale, AI workloads, and platform engineering, Helm continues to ensure they can deploy applications confidently and flexibly."
Key Features of Helm 4
1. Enhanced SDK for Developers: The Software Development Kit (SDK) in Helm 4 has been significantly upgraded, simplifying integration into various applications. This includes modern Go logging, enabling support for multiple loggers, and embeddable commands that can be utilized directly in other applications. Additionally, it features support for modern Kubernetes capabilities like server-side apply.
2. Improved Plugin System: With the introduction of a robust new plugin system, Helm 4 supports more powerful and portable plugins. Notably, plugins can now be written in WebAssembly (WASM), making them portable across different operating systems and architectures, while still maintaining compatibility with existing plugins for ease of extensibility.
3. Future-Ready Chart Features: Helm 4 sets the stage for future advancements in chart features, ensuring compatibility with previous versions. This allows for significant updates and enhancements without disrupting current user experiences. It effectively allows the introduction of groundbreaking features while supporting users who rely on established functionalities.
4. Community-Driven Development: The developments in Helm 4 are attributed to community feedback and real-world deployment experiences over the past decade. Matt Butcher, one of Helm's co-creators, reflected on the journey, stating that it is gratifying to see Helm still addresses the fundamental challenges of application deployment, albeit on a much larger scale today.
Conclusion
Helm 4 not only maintains the familiar interface and behavior that existing users rely on but also introduces substantial upgrades that cater to the modern requirements of Kubernetes environments. The release of Helm 4 coincides not just with its tenth anniversary but also with the ten-year milestones of both CNCF and Kubernetes, highlighting the rapid growth in the cloud-native ecosystem.
To learn more about the latest features in Helm 4, attendees can visit the CNCF's booth (8B) at KubeCon + CloudNativeCon North America for live demonstrations and deeper technical insights.
For those interested in leveraging cloud-native technologies, Helm 4 underscores the commitment to continuously improving the tools developers and operations teams rely on in an increasingly complex technological landscape. As cloud-native technology further integrates into the fabric of enterprise infrastructure, Helm remains a cornerstone for simplifying the deployment and management of applications in Kubernetes, enhancing the overall developer experience.
