Zephyr 2025: Roadmap, Milestones, and Strategic Priorities
From new members to our focus areas for 2025, this blog written by Amy Occhialino, 2025 Governing Board Chair for the Zephyr Project, outlines the project’s strategic plan for the year. She breaks down each goal - security, safety, developer experience, connectivity, sustainability, and dependability - and shares updates. Learn more.
Zephyr RTOS 4.1 Now Available
Zephyr 4.1 is now available with major updates including performance improvements, support for the IAR toolchain, and experimental Rust integration. This release introduces a USB MIDI 2.0 device driver, support for 70+ new boards such as Raspberry Pi Pico 2, and enhanced tools like smarter shell commands and a searchable board catalog. Performance gains since Zephyr 3.7 close the gap with other RTOSes, while expanded toolchain and language support bring new possibilities for developers. Read more.
Pathways to Cybersecurity Best Practices in Open Source
This Linux Foundation report investigates the impacts of the Cyber Resilience Act on open source software, including new cybersecurity obligations and the role of manufacturers and stewards. The report recommends investing in security tools, fostering collaboration, and addressing emerging threats such as AI-driven risks. The Zephyr Project is among the few Linux Foundation projects that provides tried-and-tested pathways for the rest of the open source community to consider when preparing for this new regulatory landscape. Read the full report here.
Doulos, Honda, Hubble Network, IAR, inovex and Microchip Technology join the Zephyr Project
In January 2025, the Zephyr Project welcomed Doulos, Honda, Hubble Network, IAR, inovex, and Microchip Technology as new Silver members, expanding our robust ecosystem. The project continues progressing toward functional safety certification, having received concept approval for IEC 61508 compliance. This certification supports Zephyr's commitment to safety, traceability, and reliability in embedded systems. Read more.

foss-north is a free / open source conference covering both software and hardware from the technical perspective. Hosted in Gothenburg between Copenhagen, Oslo, and Stockholm, the conference provide a meeting place for the Nordic foss communities and will bring together great speakers with a great audience. There will be Zephyr RTOS based talks at the event. Remember to add these talks to your schedule and attend.
Doulos recently hosted a webinar exploring Zephyr RTOS, with Percepio and NXP. This webinar addressed practical considerations for adopting Zephyr RTOS in embedded system projects. It covered Zephyr's modular and highly portable architecture, key features, licensing, and its capability in supporting connected and future-proof device development. The webinar also showed application examples featuring the NXP MCX N FRDM Development Board with Percepio Tracealyzer. Watch the webinar on demand to learn more.
