Kubernetes v1.36 'Haru' Released: Spring, Clear Skies, and a Nod to Hokusai

Overview of the Kubernetes v1.36 Release

Kubernetes v1.36, codenamed Haru, marks the first release of 2026 and brings a total of 70 enhancements to the popular container orchestration platform. Among these, 18 have graduated to Stable, 25 are entering Beta, and 25 have moved to Alpha. The release also includes a number of deprecations and removals, which users should review carefully. As always, the consistent delivery of a high-quality release underscores the strength of the Kubernetes development cycle and the vibrant support from the community.

The Theme and Logo of v1.36

Inspiration from Hokusai's Masterpiece

The theme for v1.36 draws inspiration from Katsushika Hokusai's iconic series Thirty-six Views of Mount Fuji (富嶽三十六景). The logo reimagines one of the series' most celebrated prints, Fine Wind, Clear Morning (凱風快晴), also known as Red Fuji—the mountain lit red in a summer dawn, bare of snow after a long thaw. The choice of "thirty-six views" aligns perfectly with the v1.36 milestone, and serves as a reminder that even Hokusai didn't stop there (he later added ten more prints). Created by artist avocadoneko / Natsuho Ide, the logo places the Kubernetes helm in the sky alongside the mountain, watching over the scene.

Symbolism of the Guardians and Calligraphy

At the foot of Fuji sit two cats named Stella (left) and Nacho (right), wearing Kubernetes helm collars. They stand in for the traditional komainu—the paired lion-dog guardians that protect Japanese shrines. Paired because nothing is guarded alone. Stella and Nacho represent the many paws behind the release: Special Interest Groups (SIGs), working groups, maintainers, reviewers, documentation authors, bloggers, translators, the release team, first-time contributors, and lifelong contributors returning season after season.

Brushed across Red Fuji in the logo is the calligraphy 晴れに翔け (hare ni kake), meaning "soar into clear skies." This is the first half of a couplet: "Soar into clear skies; toward tomorrow's sunrise" (晴れに翔け、未来よ明け, hare ni kake, asu yo ake). The full couplet captures the wish for v1.36—and for the entire Kubernetes project—to soar into clear skies and move toward a bright future.

Key Enhancements in v1.36

Stable Graduations

Of the 70 enhancements, 18 have graduated to Stable. While the original release announcement does not list each feature by name, stable features represent mature capabilities that have been through extensive testing and field use. Users can expect these to be enabled by default and fully supported.

Beta and Alpha Features

25 enhancements are entering Beta, meaning they are now enabled by default and likely to become stable in future releases after further validation. Another 25 enhancements are entering Alpha, giving users early access to experimental features that may change significantly. These numbers reflect the community's ongoing innovation and careful iteration.

Deprecations and Removals

As with every release, v1.36 includes some deprecations and removals. Users should review the official release notes for details on any features that are being phased out. Keeping your cluster updated and understanding deprecation timelines is essential for maintaining a healthy Kubernetes environment.

Community and Acknowledgments

The release was made possible by many hands. The editors—Chad M. Crowell, Kirti Goyal, Sophia Ugochukwu, Swathi Rao, and Utkarsh Umre—led the effort alongside countless contributors across SIGs and working groups. The logo was contributed by avocadoneko / Natsuho Ide, and the calligraphy was designed as part of the release theme.

First-time contributors and lifelong veterans worked side by side to deliver v1.36. This spirit of collaboration, embodied by the paired guardians, ensures that Kubernetes continues to evolve robustly. The release team and the broader community remain dedicated to the project's health and progress.

Conclusion

Kubernetes v1.36 offers a balanced mix of stability, new capabilities through beta and alpha features, and necessary cleanup through deprecations. The theme of Haru—spring, clear skies, and far-off horizons—invites users to soar into the future with confidence. For a full list of changes, including detailed notes on every enhancement, deprecation, and removal, be sure to read the official changelog. As the dawn breaks over Red Fuji, this release carries us toward tomorrow's sunrise.
