+- Added a new `Fifo_Signal_Source` implementation that allows using a
+  [Unix FIFO](https://en.wikipedia.org/wiki/Named_pipe) as a signal source, thus
   allowing to multiplex signal streams outside of `gnss-sdr`, letting another
   program holds access to the receiver, or allowing signal sources that are not
   supported by `gnss-sdr` but can dump the signal to a FIFO.
