  • New: “Monkey Forest” SPK measurement files can now be loaded.
  • New: “Reset” button on all tables and lists.
  • New: When “Normalise magnitude to max” is set, the “Magnitude offset (dB)” field displays the normalisation gain.
  • New: Millisecond (ms) graph option now on all time graphs except for the Wavelet view.
