- Upon first use the old settings are converted to styles and sensible defaults are set for the new features.
- The "Draw Band Background" option has been removed. It has been replaced by the color source of the dark and light band color.
- The "Artwork & Dominant Color" background mode has been removed. It has been replaced by the Dominant Color source.
- New: The background and curve peak line and area can be styled.
- Changed: X-axis mode 'Octaves' shows only 'C' notes; Mode 'Notes' shows all notes.
- Improved: Minor performance optimizations due to styles.
- Improved: Optimized the calculation of the Curve visual.
- Fixed (Beta 4 regression): Removed the DirectComposition code that enabled transparent child windows. It was fun while it lasted.
