"cgroup v2 is no longer “experimental”. Most modern Linux distributions and Kubernetes releases are moving to it by default.

As Kubernetes clusters evolve, upgrading the underlying container runtime like containerd becomes essential for accessing new features and maintaining security. Containerd 2.0, released in 2024, introduces enhancements while removing deprecated elements from v1.x.

Kubernetes Ingress handles external HTTP/HTTPS access but lacks advanced features like traffic splitting. Gateway API is its successor, offering better portability, extensibility, and role separation for teams. This guide covers migration steps, tools, and changes.

The Ingress-NGINX controller, a popular open-source implementation for Kubernetes Ingress resources, has been a cornerstone for managing external access to services in Kubernetes clusters since its inception. However, in November 2025, the Kubernetes community announced that the project would enter retirement mode, with active maintenance ceasing by March 2026. This decision marks a significant shift in Kubernetes networking, pushing users towards more modern and sustainable solutions. In this article, we'll explore the motivations behind this deprecation, available alternatives, and a detailed look at migrating to the Gateway API, including its advantages and practical examples.

This article dives into the key new features, architectural changes, breaking updates, and what they mean for users. Whether you're a DevOps engineer, developer, or Kubernetes administrator, understanding Helm 4 will help you leverage its capabilities for more efficient application deployment and management.

Kubernetes 1.35, dubbed "Timbernetes (The World Tree Release)," was released on December 17, 2025, marking another significant milestone in the evolution of the container orchestration platform. This version includes 60 enhancements: 17 features graduating to stable, 19 in beta, and 22 in alpha. It focuses on strengthening the core foundations of Kubernetes, improving scalability, security, and efficiency for diverse workloads.
