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.
