Update — Earlier this week we began testing the first release candidate on a variety of systems. We found three major bugs that needed to be fixed before release — one lingering issue related to the bug in my previous comment, and two problems involving Apple's code-signing (which is a real challenge for an application like Vuo that generates code). We're now testing fixes to those issues and continuing the overall testing.
Not sure where you are getting that from Benedikt, as I understand it the Vuo Team is currently preparing one of the next releases to fully support compatibility with new Apple Silicon / ARM64 / M1 Macs, not just under Rosetta. They've added several new nodes and updates back in October and followed with a stability release just before Christmas. Vuo has often had longer waits between releases when they are implementing big new features or making core changes that require longer development cycles.
The Vuo Team can speak better into this, but I see no reason to jump to the conclusion you made.
