CHANGES

@@ -21,6 +21,7 @@ added features:
  o Introduced `--pykat=pipename` flag. This opens a pipe between Finesse and whatever else (typically Pykat) so that data can be sent and requested between the two.
   
 bug fixes:
+ o noxaxis no longer tries to call gnuplot/python plotting
  o fixed roundtrip gouy phase sign 
  o fixed bug with frequency signal/noise, i.e. when applying fsig
    to a laser frequency
