+Changes in Sonic Visualiser 2.4 since the previous release 2.3:
+
+ - Make the octave numbering system in the GUI a configurable option,
+   and change the default. Previously Sonic Visualiser labelled
+   middle-C as "C5"; now it labels middle-C as "C4", a more common
+   standard in the world outside MIDI sequencer software. The previous
+   system available as an option in the Preferences. This affects only
+   the visible labels: there is no change to analysis or to the file
+   format
+
+ - Sonify time-value layers. Any time-value curve whose scale unit is
+   set to Hz will now acquire a playback toggle control; this control
+   is off by default, but if it is switched on, the curve will be
+   played back using a variable-frequency sound generator
+
+ - Add support for playback of note layers with non-MIDI frequencies
+   (formerly the note playback was limited to exact MIDI pitch)
+
+ - Change the default playback sample for note layers from piano to an
+   electric piano with sustain. The piano sample is still available,
+   and any sessions saved using it should continue to use it
+
+ - Shade the start and end of the main audio file, to make them easier
+   to see for files that start or end in silence
+
+ - Speed up rendering and scrolling in time-value layers
+
+ - Make it possible to import CSV files directly into Note layers by
+   adding Pitch as a data type in the CSV file import dialog
