+v2.3.0: libdlf and scooby
+-------------------------
+
+**2024-03-01**
+
+The digital linear filters are outsourced to libdlf, reducing the lines of code
+of empymod by over 50%. In addition to the new requirement libdlf, scooby is
+added as a requirement. Most user questions can be adressed much better if they
+provide the output of ``empymod.Report()`` - however, most users do not have
+scooby installed. Having it as a requirement will make support smoother. Both
+new requirements are very lightweight modules, having at most numpy as a
+dependency.
