Kubernetes v1.35: Fine-grained Supplemental Groups Control Graduates to GA
Kubernetes v1.35: Fine-grained Supplemental Groups Control Graduates to GA Motivation: Implicit group memberships defined in /etc/group in the container image What's wrong with it? Fine-grained supplemental groups control in a Pod: supplementaryGroupsPolicy Attached process identity in Pod status Strict policy requires up-to-date container runtimes Getting involved How can I learn more? On behalf of Kubernetes SIG Node, we are pleased to announce the graduation of fine-grained supplemental groups control to General Availability (GA) in Kubernetes v1.35! The new Pod field, supplementalGroupsPolicy , was introduced as an opt-in alpha feature for Kubernetes v1.31, and then had graduated to beta in v1.33. Now, the feature is generally available.

Kyverno at ContribFest: Community, collaboration, and the power of open source in action
Why ContribFest matters for open source Sharing the Kyverno story Three groups, three journeys Learning together, across experience levels Community, sustainability, and the role of supporting organizations Looking ahead to Europe Posted on December 23, 2025 by Cortney Nickerson, CNCF Ambassador and Head of Community at Nirmata CNCF projects highlighted in this post A few weeks ago at KubeCon + CloudNativeCon North America in Atlanta, the Kyverno community had the opportunity to participate in ContribFest , one of the most energizing and community-driven initiatives in the cloud-native ecosystem. While ContribFest sessions are listed on the official event calendar, many people across the broader community still don’t realize these experiences exist—let alone understand how impactful they can be for networking, learning, and truly “finding your place” within open source.

Kubernetes 1.35: In-Place Pod Resize Graduates to Stable
Kubernetes 1.35: In-Place Pod Resize Graduates to Stable What is in-place Pod Resize? How can I start using in-place Pod Resize? How does this help me? Changes between beta (1.33) and stable (1.35) What's next? Integration with autoscalers and other projects Feature expansion Improved stability Providing feedback This release marks a major step: more than 6 years after its initial conception, the In-Place Pod Resize feature (also known as In-Place Pod Vertical Scaling), first introduced as alpha in Kubernetes v1.27, and graduated to beta in Kubernetes v1.33, is now stable (GA) in Kubernetes 1.35! This graduation is a major milestone for improving resource efficiency and flexibility for workloads running on Kubernetes. In the past, the CPU and memory resources allocated to a container in a Pod were immutable.
