Kubernetes v1.37: Garhwal

Kubernetes v1.37 is named Garhwal (गढ़वाल, pronounced gaṛhvāl), after the Himalayan region of Uttarakhand, India. Inspired by its snow-capped peaks, deodar forests, terraced fields, rivers, and mountain paths, the theme celebrates a community in which every layer, route, and contribution is connected.

Imagined as a window into Garhwal, the logo shows terraced fields rising towards snowy peaks and a river gathering mountain streams. Together, they represent contributions from many SIGs and communities flowing into one project, while the deodar forest reflects an ecosystem where distinct projects share common ground and grow side by side.

A frame inspired by ringaal basketry surrounds the landscape, showing how individual contributions gain strength when woven together. Within it, the colourful Himalayan monal represents the community’s many skills and perspectives, while red buransh flowers carry Kubernetes helm symbols at their centres. A mountain house marked १.३७ (1.37 in Devanagari numerals) grounds the release in Garhwal.
