Welcome to our deep dive into Kubernetes v1.36, code-named Haru (ハル). This release marks a milestone in 2026, arriving as the seasons change and bringing a wealth of new features, enhancements, and community spirit. With 70 total enhancements—18 stable, 25 beta, and 25 alpha—v1.36 continues Kubernetes' tradition of steady, high-quality releases. This Q&A explores the meaning behind the name, the artwork, the numbers, and the people who make it all possible. Let's dive into the skies of Haru.
What is the significance of the name Haru?
The release name Haru (ハル) is a Japanese sound that carries multiple meanings, chosen to reflect the release's spirit. Among the most important are 春 (spring), 晴れ (hare, clear skies), and 遥か (haruka, distant). These three concepts capture the essence of this release: a season of renewal, clear skies for progress, and a horizon full of possibilities. The theme draws inspiration from the changing seasons and the journey of continuous improvement. Just as spring follows winter, v1.36 represents a fresh start and a moment to reflect on how far Kubernetes has come. The name also connects to the logo and the artwork, grounding the technical release in a poetic vision of ascent and exploration.
How many enhancements are in v1.36, and what are their statuses?
Kubernetes v1.36 delivers a total of 70 enhancements, a testament to the community's dedicated work. Of these, 18 have graduated to Stable, meaning they are now production-ready and fully supported. Another 25 are entering Beta, where they are enabled by default and have undergone extensive testing. The remaining 25 enhancements are coming in as Alpha, offering new functionality that is still experimental and gated behind feature flags. This balanced mix ensures that the project continues to evolve while maintaining stability. Additionally, there are several deprecations and removals in this release that users should review carefully to plan their upgrades. The enhancement breakdown reflects Kubernetes' mature release cycle, with a strong focus on graduating proven features while still innovating at the alpha stage.
What does the logo represent, and how does it tie to Hokusai?
The v1.36 logo, created by artist avocadoneko (Natsuho Ide), draws direct inspiration from Katsushika Hokusai's iconic series Thirty-six Views of Mount Fuji (富嶽三十六景). The artwork reimagines one of the most celebrated prints from that series: Fine Wind, Clear Morning (凱風快晴), also known as Red Fuji (赤富士). This particular print shows Mount Fuji bathed in red light at dawn, with little snow after the long thaw. The number 36 was chosen deliberately—it mirrors both Hokusai's original 36 views and the release version. The logo features the Kubernetes helm set into the sky alongside the mountain, symbolizing the project's watchful presence. At the base of Fuji, two cats named Stella and Nacho stand like komainu (guardian lion-dogs) at a shrine, representing the community that protects and drives Kubernetes forward.
Who are Stella and Nacho, and what do they symbolize?
In the release logo, the two cats Stella (left) and Nacho (right) serve as modern-day komainu—the paired lion-dog guardians traditionally found at Japanese shrines. These cats wear collars with the Kubernetes helm, indicating their role as protectors of the project. Their presence emphasizes that nothing is guarded alone; they stand in for the entire Kubernetes community: the SIGs, working groups, maintainers, reviewers, docs writers, translators, release team members, first-time contributors, and lifelong contributors. The message is clear: the success of v1.36—and of Kubernetes as a whole—rests on the collective effort of many hands. Stella and Nacho are a warm invitation to recognize the human side of open-source development, where collaboration and guardianship go hand in hand.
What is the meaning behind the calligraphy 'Soar into clear skies'?
Emblazoned across the Red Fuji in the logo is the calligraphy 晴れに翔け (hare ni kake), which translates to "soar into clear skies." This phrase is only the first half of a couplet that was too long to fit on the mountain. The full couplet reads: 晴れに翔け、未来よ明け (hare ni kake, asu yo ake)—"Soar into clear skies; toward tomorrow's sunrise." This poetic message encapsulates the release's optimistic spirit: a wish for the release itself, for the Kubernetes project, and for everyone who ships it together. The dawn breaking over Red Fuji is not an ending but a passage—it carries us from this release to the next, from one season to another, continually moving toward horizons far beyond any single view. It's an invitation to embrace the journey of continuous improvement.
What deprecations and removals should users be aware of?
As with every Kubernetes release, v1.36 includes a set of deprecations and removals that users must consider before upgrading. While the exact list is detailed in the official release notes, common areas include older API versions that are being removed, features that have reached end-of-life, and flags or annotations that are no longer supported. For example, some beta APIs may transition to stable while the earlier beta versions are removed. Additionally, certain deprecated features from previous releases are now fully removed, which could affect workloads that still rely on them. The Kubernetes community strongly recommends reviewing the release theme and checking the changelog for specific deprecations. Proper planning ensures a smooth upgrade and avoids disruptions. The release team emphasizes reading the deprecation notes early, especially since some removals require configuration changes or updates to manifests.
How does v1.36 reflect community involvement and contributions?
Kubernetes v1.36 is a shining example of community-driven development. The 70 enhancements came from contributors across many SIGs and working groups, from first-timers to long-time maintainers. The release team, including editors Chad M. Crowell, Kirti Goyal, Sophia Ugochukwu, Swathi Rao, and Utkarsh Umre, worked to coordinate this complex effort. The logo and theme itself were inspired by community artwork—artist avocadoneko contributed the design. The inclusion of Stella and Nacho as guardians symbolizes the collective stewardship that makes Kubernetes thrive. The release notes highlight the contributions of countless individuals who handle documentation, blogs, translations, and testing. Moreover, the release continues the tradition of acknowledging that every release is held up by many hands. The v1.36 cycle demonstrates that open-source collaboration remains Kubernetes' strongest asset, and that each release builds on the shoulders of the previous one.
