GNU Radio 4.0.0 Release Candidate 3 (RC3) is now available! While this release brings significant improvements to the runtime, expanded signal processing capabilities, and continued progress on developer tooling, it also marks an important milestone for the GNU Radio project: RC3 is the first GNU Radio 4 release candidate maintained by the broader GNU Radio community.

Software-defined radio (SDR) has become a foundational technology across radar, electronic warfare (EW), spectrum monitoring, counter-UAS, and advanced wireless communications systems. Its flexibility allows engineers to rapidly develop, test, and refine new capabilities without being constrained by fixed-function hardware. Yet while SDR enables rapid innovation in the lab, transitioning those capabilities into deployed systems introduces a distinct set of challenges that can impact performance, development timelines, and long-term adaptability.

We have been working hard getting GNU Radio 4 ready for an official release. Part of this endeavor has been restructuring and refactoring the repositories for future maintainability, better build and CI efficiency, and the flexibility to support different licensing models across the ecosystem. GNU Radio 4 is now organized around a super-repo builder capable of pulling together foundational projects such as the core runtime and key DSP libraries, modules containing both official and experimental blocks, and applications built on top of them.
The European GNU Radio Days will be held in Rennes, France, from November 16 to November 18, 2026. The event aims to bring together the European SDR community around scientific presentations, technical feedback, tutorials, demonstrations, educational materials for students, and discussions on the evolution of open radio technologies. This new edition of the European GNU Radio Days will focus on cybersecurity with SDR.
As of Monday, Google Summer of Code, 2026 edition, has been in its hot phase!

Today, GNU Radio is reaffirming that GNU Radio 4 will continue as an officially community-maintained release line under the GNU Radio project’s established governance structure. Development will proceed from the official GNU Radio 4 GitHub repository, which contains the MIT-licensed core code base, and we encourage users and contributors to follow and participate.

GNU Radio 4.0 RC1: A New Foundation for High-Performance Signal Processing GNU Radio 4.0 has reached its first release candidate (RC1)—a major milestone that signals the transition from active development to near-production readiness. See the tag for all the details. At this stage, the core architecture is stable, the execution model is well-defined, and the API is no longer expected to undergo major breaking changes.
Hooray! GNU Radio has once again been accepted as a mentoring organization for Google Summer of Code 2026. This means that we will soon be accepting proposals from students/contributors who want to spend their summer hacking on GNU Radio. While we have updated our ideas list with projects ranging from GPU acceleration to GNU Radio 4 ports, we encourage you to propose your own project ideas!
Enjoying Some Publicity You’ll find GNU Radio being featured in thousands of scientific publications, you can find it featured in books, university curricula, space, on railroad tracks and dedicated conferences on at least three continents. But frankly, I’ve been missing the time where I could venture out on the internet and just find someone just writing something about GNU Radio out of the sheer fun of bringing new concepts to people who would otherwise have missed a whole world of such things.
Originally published on libvolk.org Hi everyone! This is the VOLK v3.3.0 release! We want to thank all contributors. This release wouldn’t have been possible without them. We received a lot of improvements to existing kernels, new kernels, and optimized support for a lot of existing kernels. Moreover, a lot more implementations make use of AVX512 now, as well as more optimizations for RISC-V, and more NEON implementations.
