Project Talk: Maintenance Update
summary
Maintainers report an active strategy: a quarterly cadence of releases, tracking master while selectively backport to 3.9 and 3.8, keeping PR backlog around 20–30 and naming unreviewed PRs the main bottleneck. Tooling enforces clang-format, signed GitHub releases, CI on multiple container targets, and contributor sign-offs. Concrete upstream work includes SoapySDR integration, gr-iio and grpdu modules, removing log4cpp in favor of spdlog, an experimental zero-copy accelerator buffers PR, and a new scheduler prototype aimed at multi-core mappings that shows up to 3× speedups.
