Some deprecations in GNU Radio 3.8 


Modules gr-comedi, gr-fcd and gr-wxgui have been removed.


Gr-comedi has been removed as it had 0 active code contributions in the 3.7 lifecycle.


Gr-fcd is getting removed as it is currently untestable by the CI and as there were no code contributions.

It seems few users are excited to experiment with GNU Radio 3.8 in the near future. A user commented on HackerNews, “GNU Radio is one of those examples of free software being hyper-niche yet super successful. It’s something I want to start playing with in the near future.”
