A brand-new RAR engine derived by Shay Green from the latest UnRAR sources means all RAR files including ones created with the latest versions of RAR and WinRAR should now work fine.
Added engines for .COP, .ORC, .PSF, .QSF, .S3M, and .S98 formats.
MOD engine has greatly improved compatibility and now auto-analyzes MODs in an attempt to better support common types. Big thanks to MLD from the UADE project (http://uade.ton.tut.fi/). If you need perfect MOD playback on non-Amiga hardware, look no further than UADE.
(Mac) The application can now be quit by closing the main window.
(Mac) Reduced CPU usage substantially when music playback is paused.
(Mac) Disabling the oscilloscope has a much more dramatic effect on performance now.
