GNU Radio Beyond 3.8 - A Technical Outlook
summary
Release 3.8 is out and master becomes the primary development branch while bug fixes get backported, with a cadence of roughly two releases a year. The roadmap specifically drops Python 2, upstreams device stacks like G and G IIO, and prototypes a new scheduler that maps blocks to workers with a single queue per worker to improve cache locality. gr-scet benchmarking already shows throughput gains in the tens of percent and the refactor aims to enable zero-copy accelerators and cleaner message/stream blending.
