  "account": "Anaheim, California – September 21, 2026 – Canonical has announced the upcoming release of Zephyr 26.04 LTS, an enterprise-ready distribution of the Zephyr RTOS. This long-term support version builds on the upstream Zephyr project with additional support for device management and microcontroller components. The distribution is available as part of an Ubuntu Pro for Devices subscription and is aimed at silicon vendors and ODMs/OEMs building and maintaining MCU-grade embedded products.\n\nZephyr 26.04 LTS brings enterprise-grade reliability and security to the microcontroller ecosystem, addressing the growing pressure on device manufacturers to maintain firmware over extended lifecycles. With tighter regulations and higher device deployment scaling, Zephyr 26.04 LTS provides the predictability of Ubuntu's release cycles and enterprise-grade security to the microcontroller environment. This enables manufacturers to source support for both Linux-class and microcontroller-class devices from a single vendor.\n\nCanonical has invested over two decades in earning trust in open source, starting with Ubuntu. The new long-term support model for microcontrollers is a natural extension of that commitment. As someone deeply involved in the Zephyr community, Jonathan Beri, Head of Product, IoT at Canonical, is excited about the project's maturity and proud to contribute.\n\nThe EU Cyber Resilience Act entered into force, mandating a minimum of 5 years of security maintenance for devices. Zephyr 26.04 LTS exceeds this requirement, offering up to 15 years of security maintenance. This provides manufacturers with a stable foundation for compliance without disruptions. Stability is achieved not only through extended patching but also through a stable release cycle. Zephyr 26.04 LTS follows the same release cadence as other Canonical products, with LTS releases every two years and interim releases every six months.\n\nThe Zephyr 26.04 LTS commitment extends beyond Zephyr itself to include essential tooling from the microcontroller ecosystem, such as West, a widely adopted meta-tool for managing repositories, building, and flashing firmware. This mirrors Canonical's comprehensive maintenance and provenance model for Linux-class devices via Ubuntu Pro.\n\nCanonical's new support offering addresses the complex requirements of embedded developers and manufacturers, including new cybersecurity regulations like the EU Cyber Resilience Act. This long-term solution helps organizations confidently integrate open source technology into production. Avnet, a key partner, is excited to expand its partnership with Canonical, providing customers with an enterprise-grade RTOS option backed by long-term support and reliability.\n\nZephyr 26.04 LTS also natively supports Golioth Cloud's software update capabilities, including secure software updates directly to microcontrollers in the field. This complete delivery pipeline satisfies CRA field-update requirements without the burden of building custom tools. Canonical is introducing support for Zephyr LTS releases within Canonical Workshop, a containerized development environment that allows developers to access a ready-to-use Zephyr LTS environment on any hardware, streamlining onboarding and collaboration.\n\nRenesas Electronics, another partner, sees the combination of Renesas' long-lifecycle embedded processing products with Canonical's enterprise-grade long-term support for Zephyr as a powerful combination. This will accelerate the adoption of Zephyr for long-lived commercial products, providing hardware longevity, software stability, and security maintenance across the entire product lifecycle.",
