Release Notes

About KLANG Updates

KLANG releases major updates approximately 1–2 times per year, introducing new features and improvements.
A major version step is indicated by a change such as 4.x → 5.x or 5.5.x → 5.6.x.
These updates include simultaneous releases of both KLANG:app and KOS.

In addition, there are minor updates (e.g., 5.5.x → 5.5.y) for both KOS (KLANG Operating System) and KLANG:app.
These contain important fixes related to:

  • Changes in operating systems (iOS, Android, macOS, Windows)
  • Support for newly released smartphones or tablets
  • Compatibility with third-party hardware, such as DiGiCo consoles

Minor updates are released more frequently — sometimes several app versions per month — to ensure the best possible user experience and compatibility with the latest platforms and devices.
