 ### Improvements in Usability:
 
+- 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.
 - Avoid segmentation faults in the flow graph connection and/or starting due to
   some common inconsistencies in the configuration file.
 - Provide hints to the user in case of failed flow graph connection due to
