The first Alpha for Helm v4 has been released. Now that Helm v4 development is in the home stretch, we wanted to share the details on what's happening and how the broader community can get involved.

If you are installing helm with Apt, be aware that the Debian/Ubuntu Helm Apt repository is moving.

It's that time of the year again – the Helm team is headed to KubeCon + CloudNativeCon EU '25 in London, UK this week from April 1 - 4! Helm 4 is in the works for later this year so be sure to join the conversation with our maintainers during our talk sessions and at our Helm booth in the Project Pavilion! See below for more details on all Helm-related activies throughout the week.

Have you ever wondered what it takes to perform a software release of one of the most popular tools in the Kubernetes community? While you may envision a series of complex steps or maybe even some black magic (some of which may be true), the release process is much more organized and streamlined than you may have envisioned. However, until you see it for yourself firsthand, these types of questions will continue to go unfulfilled. Seeing it really is believing it!

Helm is going to be at KubeCon / CloudNativeCon North America in Salt Lake City. There will be something happening each day of the main conference, including:

Over four years ago, we introduced Helm 3, a major evolution in Helm's development. And we announced at that time that Helm 2 would receive patches and security updates for a year. We also provided a migration path to Helm 3 from Helm 2 and a tool helm-2to3 to automate migration.

We have been saying it for a while now – Helm is "stable software". That should not come as a surprise to anyone familiar with Kubernetes and the surrounding ecosystem as many within the Kubernetes community consider Helm to be the de-facto package manager. The use of Helm is far reaching: from open source community projects, to startups, to Fortune 500 organizations. Helm has become an essential component of build and deployment workflows that handle mission critical workloads.

CVE-2019-25210 was recently filed against the Helm project. This action was completed without engaging the Helm project and working through the documented security process and team. The Helm project was given no notice before the disclosure was released which resulted in the inability to provide an appropriate statement beforehand. This post serves as the response from the Helm project.

Helm 3.13 brings some significant and useful changes for Helm users. This ranges from longtime bugs being fixed to some new features that can have an impact on performance.

Helm introduced full support for storing charts within OCI registries as a distribution method beginning in version 3.8, and while this feature has been available for some time now, there is more underneath the hood than one may realize to make this capability all possible. A number of concepts, working in unison, make it possible to store content aside from traditional container images within OCI registries. This article will explore one of these important concepts, Media Types, their purpose, and how Helm’s own set of Media Types make it possible to extend the storage of charts beyond standard chart repositories to OCI registries.
