The MUI development team is proud to announce the immediate release of version 5.0-2019R4 of the Magic User Interface for AmigaOS4/PPC and AmigaOS3/m68k. The new release of MUI5 for AmigaOS3/m68k is definitely targeted at powerful systems with a fast CPU and a fast graphic board. Although it is still possible to run this release on a real 68k machine, emulation packages such as WinUAE are very recommended. Also colour-mapped screens with 256 colours are still supported, but MUI5 makes heavy use of fancy truecolour images and effects which cannot be provided on colour-mapped screens with the full range of possibilities. Like all former releases a keyfile is required to enable all available settings. Old keyfiles from MUI 3.8 can be used without any restriction.
