What's new ?

This page describes the improvements of Melody and Harmony Assistant.
How does our version notation system work?
The version looks like this :
  • When we make a major change we add one to X.
  • When a new feature is added, we add one to Y
  • When a bug is fixed or a cosmetic detail is corrected, we add one to Z
Melody version 1.0 matches Harmony version 3.0.
If you own Melody, subtract 2 from the Harmony's major version number to know the changes made in your version.
