+# PaleoSpec 0.3
+
+* Add FilterSpec and FilterSpecLog as replacements / alternatives to LogSmooth
+
+ FilterSpec and FilterSpecLog uses ApplyFilter to (optionally) avoid loosing the
+ highest and lowest frequencies when smoothing a spectrum. Default behaviour is 
+ method 3: min roughness (reflect and invert ends). Avoids the artefact seen at 
+ high freqs with LogSmooth.
