For those of you who have already installed M5.0.39 you can use the 'Quick Patch' links to grab the newest app patches. That's easier and faster than having to download the complete new package and copy your user settings.
What's changed since M5.0.39:
- Fixed a crash bug when doing "Close All Module Editors" when VST editors are open.
- Fixed a problem when replacing a VST plugin by another VST plugin while having opened a generic VST editor for that plugin.
- Increased stability of the VST plug-in interface.
- OSX: Fixed a problem with drag-dropping external files into MuLab / MUX.
