+
+
 #### v0.8.27
 - A little optimization in method `meico.audio.Audio.convertSpectrogramToImage()`. In addition, this method has been extended with a new argument `normalize` to give applications the possibility to decide whether the spectrogram values should or should not be normalized for rendering.
 - Internal Verovio update to v3.7.0-dev-e93a13d.
