Welcome to the Kubernetes v1.36 release, codenamed Haru (ハル), a name that evokes spring, clear skies, and distant horizons. This release, arriving as 2026 begins, brings a fresh breeze to the cloud native landscape with 70 enhancements. The consistent delivery of high-quality updates reflects the strength of the Kubernetes development cycle and the vibrant community support. From stable graduations to new alpha features, and from deprecations to a beautiful release theme inspired by Hokusai's iconic prints, there's much to explore. Here are the 10 things you need to know about Kubernetes v1.36 Haru.

1. The Spring Theme: Haru, Mount Fuji, and Clear Skies

The v1.36 release theme draws from the Japanese word Haru, which signifies spring, clear weather, and the far-off. The logo, created by artist avocadoneko (Natsuho Ide), reimagines Katsushika Hokusai's famous print Fine Wind, Clear Morning (also known as Red Fuji). The mountain stands illuminated in a summer dawn, bare of snow after the long thaw. The Kubernetes helm is placed in the sky alongside the peak, with two cats named Stella and Nacho acting as komainu (guardian lions) at the mountain's base. The calligraphy reads "hare ni kake" — "soar into clear skies" — embodying the hope that this release carries everyone toward a brighter future.

2. 70 Enhancements: Stable, Beta, and Alpha Graduations

This release packs 70 enhancements in total, continuing the trend of steady innovation. Among them, 18 features have graduated to Stable, marking them as production-ready. 25 features are entering Beta, meaning they are enabled by default and well-tested. Another 25 features debut as Alpha, offering early access to experimental capabilities. This balanced mix ensures that Kubernetes remains both robust and forward-looking, catering to users at every stage of adoption.

3. Key Stable Features: What's Now Production-Ready?

The 18 features that reached Stable in v1.36 include improvements to workload management, security, and networking. For example, enhancements to Pod Security Policies have been fully replaced by the more flexible Pod Security Standards, giving cluster operators finer-grained control. Additionally, the CSI Volume Snapshot functionality is now stable, allowing administrators to back up and restore persistent volumes reliably. These stable features are battle-tested and recommended for production clusters.

4. Notable Beta Features: Enabled by Default

The 25 features entering Beta bring practical improvements that will soon become the norm. One standout is the Node Swap feature, which allows pods to utilize swap memory on nodes, improving resource efficiency for memory-intensive workloads. Another is the Dynamic Resource Allocation update, which simplifies how pods request and access hardware accelerators like GPUs. Beta features are enabled by default but can be toggled via feature gates if issues arise.

5. New Alpha Features: Experimental Innovations

Among the 25 alpha features, several promise to reshape Kubernetes operations. The In-Place Pod Vertical Scaling alpha allows CPU and memory requests to be adjusted without restarting the pod, a boon for stateful applications. Another alpha, Storage Capacity Tracking, helps the scheduler make smarter decisions by considering available storage space on nodes. These features are behind feature gates and invite community testing and feedback.

6. Deprecations and Removals: What's Being Phased Out

With every release, some components retire. In v1.36, several deprecated APIs and features have been removed. Notably, the Ingress API version networking.k8s.io/v1beta1 is no longer served, and users must migrate to the stable v1 API. The NodeStatus.NodeAddress field has been streamlined, and legacy PodSecurityPolicy resource is completely absent (superseded by Pod Security Standards). Check the full deprecation notes to ensure your manifests are up to date.

7. The Logo: Inspired by Hokusai's Thirty-Six Views

The v1.36 logo pays homage to Katsushika Hokusai's Thirty-six Views of Mount Fuji, specifically the print Fine Wind, Clear Morning (Red Fuji). The number 36 aligns with the release number. The artwork features the Kubernetes helm as a celestial presence, while two guardian cats — Stella and Nacho — represent the many contributors (SIGs, working groups, maintainers, translators, and release teams) who safeguard the project. The calligraphy "hare ni kake, asu yo ake" (soar into clear skies, toward tomorrow's sunrise) captures the spirit of continuous progress.

8. Community and Contributors: Many Hands Make Light Work

The release of v1.36 is a testament to the global Kubernetes community. Editors Chad M. Crowell, Kirti Goyal, Sophia Ugochukwu, Swathi Rao, and Utkarsh Umre led the effort, supported by countless SIG members, first-time contributors, and long-time veterans. The theme's guardian cats, Stella and Nacho, symbolize this collaborative spirit — nothing is guarded alone. Whether you're a developer writing code, a doc writer clarifying concepts, or a translator broadening access, your work is celebrated.

9. Release Cadence and Quality: Steady as the Seasons

Kubernetes v1.36 follows the project's reliable quarterly release cycle. The consistent delivery of high-quality releases underscores the maturity of the development process. Each enhancement undergoes rigorous review, testing, and graduation criteria. The community's dedication ensures that even as the project scales, stability remains paramount. This release cycle allows enterprises to plan upgrades with confidence, knowing they receive predictable improvements.

10. Looking Ahead: Spring into the Future

As the v1.36 logo suggests, the dawn breaking over Red Fuji is not an ending but a passage. Hokusai, after his initial 36 views, added 10 more — a reminder that innovation doesn't stop. Kubernetes v1.36 carries us to the next release, and that one to the one after, on toward horizons far beyond what any single view can hold. For now, soar into clear skies with Haru, and embrace the spring of cloud native computing.

In summary, Kubernetes v1.36 Haru delivers 70 enhancements (18 stable, 25 beta, 25 alpha), deprecations, a beautiful Hokusai-inspired logo, and a reaffirmation of community strength. Whether you're upgrading a cluster or exploring new features, this release offers a fresh start. For more details, refer to the enhancements breakdown or the deprecations list. Happy spring!
