Why this commit and not just the latest release 1.3.2?

> +      (description "liquid-dsp is a free and open-source digital signal

> +embedded platforms. The aim is to provide a lightweight DSP library that does
> +not rely on a myriad of external dependencies or proprietary and otherwise
> +cumbersome frameworks. All signal processing elements are designed to be
> +flexible, scalable, and dynamic, including filters, filter design,
> +oscillators, modems, synchronizers, complex mathematical operations, and much
> +more.")

Please remove “free and open-source” — all software in Guix is free
software, so we don’t need to state it.  Please also use double spacing
after each sentence.
